High-res audio

The future is now…and very affordable

Game-changing surround sound technology doesn't come around often – and rarely at such an affordable price. The Onkyo TX-NR636 can make sound rain down with Dolby Atmos® technology (available with a firmware update) and a set of in-ceiling speakers or Atmos enabled up-firing speakers.  We shouldn't be surprised – Onkyo's been delivering a lot of home theater bang for our customers' bucks for many years.  Beyond Dolby Atmos, this receiver offers other forward-looking features like HDMI 2.0 connectivity and Marvell Qdeo™ 4K video processing, for Ultra HD video quality. Plus, it's compatible with the latest HDCP 2.2 copy protection, so you'll be ready to watch 4K broadcasts when they're available.

Dolby Atmos adds a new dimension to sound

Dolby's latest surround sound technology was designed to bring a new level of immersion to your home theater. By employing in-ceiling speakers or special Dolby-enabled upward-firing speakers that reflect sound off your ceiling, Dolby Atmos offers a greater sense of space for sound that's more three-dimensional. Already at work in film production studios and many movie theaters, Dolby Atmos represents a huge step in putting more "theater" into your home theater.

The TX-NR636 lets you add two overhead or up-firing speakers (sometimes called "height" or "top" speakers) to a conventional five-channel system — this is referred to as a 5.1.2 Dolby Atmos setup. You can use either one or two subwoofers with this setup.

Wi-Fi and Bluetooth offer lots of music choices

Music is increasingly delivered from sources other than shiny discs. Smartphones, tablets, computers, Internet radio, and subscription services offer a wealth of listening options. You can take advantage of all of them with the TX-NR636. Stream music from smartphones and tablets over Bluetooth, to play audio from any app through your home theater speakers. If you have a digital music library stored on a networked PC or storage drive, Wi-Fi lets you play those tunes over your home network. There's also built-in support for Spotify®, Pandora® Internet radio, SiriusXM, and free Internet radio streams via TuneIn radio. With so many choices, you'll never have trouble finding something to listen to. Plus, Onkyo's Music Optimizer helps restore musical enjoyment to compressed files and Bluetooth streams.

Emphasis on sound

The 'NR636 is about more than just convenience and versatility. Onkyo has always put a premium on sound quality. This receiver features their Wide Range Amplifier Technology, which provides plenty of current to ensure smooth sound even during large swings in dynamics. This reduces distortion while ensuring music and movie soundtracks have plenty of punch. Phase-Matching Bass Enhancement keeps low-frequency tones from muddying the midrange, so you get plenty of deep bass while vocals and dialogue remain clear and detailed. And if you've downloaded high-resolution music from sites like HDtracks, you'll appreciate this receiver's ability to decode high-res files like FLAC, WAV, Apple Lossless, and even DSD.

Add music to a second room

If you'd like to add speakers to an adjoining bedroom, kitchen, or porch, you can plan ahead with the 'NR636. There are powered Zone 2 outputs, so you can connect an additional set of speakers for use in another room. While the rest of the family enjoys a movie in 5.2-channel surround sound in the home theater, you can chill out on the porch and listen to music from Spotify® or your networked computer. There's also a second HDMI output, just in case you'd like listen to music in the main room and send the kids to another room to watch their movie.

Simple setup and control

The tiny microphone that's included with the TX-NR636 is your key to properly calibrated home theater sound. Plug it into the front of the receiver, and let Onkyo's AccuEQ optimize your system for your room and speaker setup. This ensures you'll get the best possible sound in your room, even if its odd layout forces you to place speakers in less than ideal locations. Before you start exploring this receiver's features, be sure to download the Onkyo remote app to your Apple® or Android™ smartphone. It offers easy control of the receiver's most important functions, as well as giving you instant access to Internet radio and other online music choices.

    Avoid - not reliable

    Written by: Joe S from Danville, CA on February 6, 2016

    Ordered this receiver in December 2014. All was working well until a few weeks ago when it would turn on and off constantly. After messing around with it for a while, yanking out speaker connections, etc. it might start working again. But the next day, same thing. Reviews on other sites confirmed my fear... very low quality capacitors are used that end up shorting out and triggering a receiver shutdown. The fix? Spend close to $75 to send it to Onkyo for repair where they swap out the system board/capacitors with the same exact junk. After a few months, the same thing happened again. I decided not to invest further and ended up buying a different brand. My advice would be to avoid Onkyo products as a result.

    Pros: Great sound Solid features Easy setup

    Cons: Not reliable Aggravating

    Very good value

    Crutchfield Customer Review (What's this?)

    Hands down the best receiver/amplifier I've owned in my lifetime, and I'm 66. The previous one was in 1987 and I paid three times as much.

    Pros: Exceptional sound for the price-point.

    Cons: When using at first as just an audio amp/receiver, had to drag in a monitor for the set up.

    Awesome product

    Written by: Chris from Pennsylvania on September 8, 2015

    One of the best receivers I've purchased thus far. Replaced this from a previous receiver pioneer vsx-1124-k. The difference is Night and Day. As for the heating issue, buy a on fan that can be used for a notebook/laptop. Problem solved. Wifi was simple, I use it everyday through my server to watch movies and listen to music from my computer. Every input/output works perfect with my setup. Sound quality is superb and I haven't even used this receiver to its full potential yet. Currently I have a 5.1 set up with BIC America Speakers and an Acoustech subwoofer..

    Pros: Quality, Sound, Versatility, price.

    Cons: Only con is the zone 2 feature which could have had more thought put into it. Other than that a must buy receiver for the price.

    Onkyo is not what it used to be, Do Not Buy!

    Crutchfield Customer Review (What's this?)

    So bad. I don't really know where to start. Before I begin I want to say that I am an electronics technician/network administrator with 20+ years of experience with all types of electronic devices and setups. After one night with my new 636 amp I can honestly say that I have never worked with a more defective and poorly engineered piece of electronics in my entire career.

    First of all, the amp runs hot, I mean really hot. Like it hurts to touch the top of the amp for more than a second or two after only about 10 minutes of it being powered on (not even playing audio, just being turned on and sitting idle). I would consider it a fire hazard. Next, the hdmi board flickers, cut-out, and in general just struggles to display anything correctly...and this was only after about 20 minutes of usage, and probably related to the ridiculous amount of heat this amp puts out. The optical audio input did not work... all assignments were made and outputs correctly set, but still no audio. My other amps can play from the same optical cable, but not this Onkyo. How fantastic. I also could no get the amp's WiFi to connect to my router, despite my 20+ years of experience in computer networking and network administration. The remote doesn't register all key strokes, and seems to lag when entering multiple commands in succession. Essentially, this is an expensive self-igniting paperweight that performs like a off-brand A/V receiver.

    Pros: I dunno, still trying to think of some. I did learn to never purchase anything from Onkyo again, so there's that.

    Cons: Everything. Onkyo is not what it used to be. This was the single worst experience i have ever had buying/installing electronics. Nothing about this amp is worth the price tag.

    Nice reciever

    Crutchfield Customer Review (What's this?)

    Replaced an old reciever that did not have enough HDMI inputs. Crutchfield rep asked a lot of questions and recommended this one. Switching receivers was very straight forward. All is working very nicely. The old reciever was installed by professionals. I would up having to trace wires and discard a few. Crutchfields labels were a great help. Tech support was excellent. Recommended I use optical cable for the smart TV functions. Could not be happier with the reciever or Crutchfields

    Pros: Easy straightforward setup. Easy to follow instructions

    Cons: None so far. I should have switch receivers sooner

    Excellent receiver for the price

    Great reciever. The only problem is that it takes a little time when turning on TV for picture and sound. Called and was told that it was because the stereo and tv had to communicate with each other. Hook up was fairly easy.

    Pros: Great stereo.

    Cons: The time it takes to communicate with each other.

    The reciever came in on time and was a great price. The set up was easy and fast due to the fact I was up grading from one Onkyo reciver to this one. Great power and use the internet too. I am now using Spotify.

    Only had it for a few days, but seems to be a good piece of equipment. I bought it to replace my 10 year-old TX-SR602 which had no HDMI connections.

    Pros: Ease of connecting other components. Easy to set up and operate.

    Cons: Only one digital optical audio input.

    Onkyo TX-NR636

    Written by: Steve from Arizona on May 18, 2015

    Crutchfield Customer Review (What's this?)

    This was purchased as a 'fill-in' for my Yamaha RX-A2020 that was in the shop. This is a great piece of equipment and will make you wonder why you didn't give it a shot to begin with. Although it is not as feature-laden as the A2020, the Onkyo TX-NR636 is fantastic. It has plenty of power, enough that it fills my entire home with music. The availibility of the Dolby Atmos option blows us away and Onkyo's AccuEQ will optimize your system for your room and speaker setup in minutes. Add to this the built-in Bluetooth and WiFi, allowing access to Pandora, Spotify, SiriusXM, et al, and then the Apple apps are the icing on the cake! I was thinking of retiring the NR636 to the bedroom when my Yamaha is repaired, but.... Well, it may have found, no, it may have EARNED its place in the front room instead!

    Pros: Its an ONKYO!

    Cons: Not happy with the 'slip-on' antenna connection most of these receivers have, they sometimes tend to slip-off, although it does seem a bit more secure on this unit than others.

    Nice Receiver

    Crutchfield Customer Review (What's this?)

    I was looking for a receiver that was easy to setup and had good support for digital music. I found it with this one. The sound quality is really good too. My wife has always had a hard time understanding words in songs. One evening after setting this receiver up she was fiddling on her phone while I was playing Mr. DJ picking music from my PC resident digital collection I thought she would like. She appreciated my selection and then said, I can clearly hear the words to these songs. Anyways I found this receiver very easy to setup and learn about through experimentation. The sound is good and it has all of the features I was looking for. I like the Android App you can download for it too. The only problem I had with setup was I accidently shutoff the receiver video output and since I was so new to the device couldn't figure out how to turn it back on. At first I thought it had gone bad but then after looking up how to do a factory reset, started over again and was careful not to repeat that mistake again.

    Pros: Good variety of features including digital music. Very good sound quality which you obviously want in a receiver unit. Nice Android App. Includes the new 4K video encryption standard.

    Cons: Equalizer could have a little more banding but didn't make me regret the purchase.

    Crutchfield Customer Review (What's this?)

    After much research and advice from Crutchfield I decided on the this receiver. Shipping was very fast to Hawaii and free. Set up was pretty much straight forward although I did call tech support for help on some settings (great guys, always very knowledgeable and courteous). I also bought the Onkyo Atmos speakers for my front high speakers. My old amp did not have HDMI connections or internet capabilities, this thing is amazing. The sound quality from Pandora blows me away. Still learning some of the functions and settings. The video up conversion is not what I expected, I may have to make some adjustments. Well worth the money!

    Pros: Ease of set up, sound quality and of course customer support from Crutchfield.

    Cons: None right now.

    Great value but component video conversion at 480i

    Written by: Craig from Central Ohio on March 30, 2015

    Crutchfield Customer Review (What's this?)

    For the money, this is a great value considering Dolby Atmos and HDCP 2.2 compliant. I found the set-up very easy and intuitive and the video source switching works great with my Viewsonic projector (the Yamaha 1040 I previously purchased had all sorts of compatibility issues with the projector so I returned that one). I also like the ease with which I can customize the 2 HDMI outputs. The only negative thing I can say, but for me it's a big negative, is the HDMI conversion of component video. The receiver will not convert anything over 480i so while my original Xbox has component video cables and some games that run (and look pretty good) at 480p and 720p, the receiver requires that you "downscale" video to 480i if you wish to output it through HDMI. Given that my projector does not have component video inputs, that means my original Xbox looks pretty weak on the big screen. The only other possible negative is that there is no built-in Apple Airplay but just buy Apple TV and your problem is solved (I also think Apple Airplay through Apple TV may be better anyway). So with the exception of the component video conversion issue, I think this is a great receiver, especially at this price point..

    Pros: Easy and intuitive set-up, Dolby Atmos, HDCP 2.2 compliant.

    Cons: Component Video Conversion limited to 480i.

    Outstanding!

    Crutchfield Customer Review (What's this?)

    Have had this receiver for over a week and have put it through its paces. Invest the 10 minutes to auto calibrate the sound; it made a huge improvement. This unit delivers all that it promised, and more. The sound is clear and rich on any input. Plenty of power for my typical 2000 square foot house. Crutchfield technical help before the purchase was awesome. Definitely coming back for my next electronic purchase. Enjoy!

    Pros: Crutchfield service and technical expertise, the unit delivers all that it claims and definitely compares nicely to the upgraded model (that is $700 more). The auto calibration system works very well and is worth the ten minutes after you think you've achieved optimal results. I suspect the auto calibration will improve your settings.

    Cons: None so far.

    Crutchfield Customer Review (What's this?)

    So far, I am very pleased. Great number of features, especially at this price. I wanted Dolby Atmost, which in other receivers started at $1,500 and up. Installation was fairly easy with on-screen prompts. The remote is a little confusing and not the easiest to use, but everything else is great - audio sounds great and video is enhanced over what I was previously getting.

    Pros: Lots of features. Easy set-up. Looks and sounds great.

    Cons: Remote could be better designed. Otherwise, no cons so far.

    Crutchfield Customer Review (What's this?)

    I used this receiver to replace a Marantz 1403. I was happy with Marantz but wanted more features (thank you Crutchfield for your return policy). After installing this Onkyo, I bi-amped my front speakers, wow, what a difference. I am very pleased with the change. I replaced an older model Onkyo with no HDMI inputs so I was familiar with Onkyo products. I am still fine tuning the speaker settings but am very happy with the sound and power this receiver produces. I can definitely tell a difference in the power to the speakers. I am somewhat disappointed because I wanted to replace my front towers, B & W DM 603 S2's, to match my new Martin Logan Electromotion C2 center channel and Martin Logan LX16 surrounds but I am so happy with the sound, I no longer want to buy new towers. I also have an older model Velodyne CT120 subwoofer that just impresses me every time I watch a movie. The ARC feature is cool as once you get the settings right (I had to turn off the CEC setting on my TV and turn on HDMI control on receiver) one remote turns all your equipment on and off. This receiver seemed to complete my home theater set up. Happy with receiver and recommend it highly.

    Pros: Great sound, easy to set up, great power.

    Cons: none at this time

    Crutchfield Customer Review (What's this?)

    I've had this unit for about 2 months. Needed to replace my A/V Receiver after purchasing a UHDTV. The unit was recommended to me by a Crutchfield rep because it supported 4K, HDMI connections and 100 watts per channel. The rep was right on with his recommendation. I'm extremely satisfied with this unit. It's easy to set up and use, and has all the features I wanted. No need to replace my current speaker system since it met my 8 ohm, 100 watt requirement. With the addition of 2 height speakers, it will allow me to upgrade from my current 5.1 to a 7.1 channel system in the future.

    Pros: Just about everything. This product meets my expectations and it's a great value.

    Cons: Although my Samsung UHDTV and this receiver both have ARC, it doesn't work and didn't eliminate the need for a separate audio connection. The Crutchfield rep even recommended this set-up over using ARC. ? ? ?

    Excellent Value, Great Sound

    Crutchfield Customer Review (What's this?)

    I bought this receiver to replace an 8 year-old Denon 887 that was showing age (still souded amazing but lacked advanced HDMI inputs and lossless audio codecs). I use the receiver as part of home theater system solely (no CD music, no streaming audio or radio) and I very much liked the idea of this receiver in that ecosystem because: (1) it has a copyright compliant 4K HDMI input and output, making it somewhat future-proof for video; (2) it supports lossless codecs, including Atmos; (3) Onkyo can update the firmware periodically via internet, keeping the receiver useful for a longer period of time; (4) by all reports I read it has the power to produce a satisfying home theater experience. I have not been disappointed with the receiver. In addition to all the features above the receiver has surprised me other respects. Not only is it capable of updating its firmware via WiFi (I read it could only do this via USB or ethernet), it has more than enough HDMI inputs to support all of my home theater clients - Chromecast, Roku, PS3, BD Player (this had been a limitation on my old Denon). Some people don't like the user interface but I don't mind it at all. The receiver has more than enough power to operate my KEFs plus the Onkyo Atmos speakers I paired with the system. Atmos is subtle but noticeable on the Transformers BD. Very pleased, over all - especially at this price point (given all receivers will eventually need updating again).

    Pros: Great sound, nice future-proofing, lots of inputs. I loved that I could update firmware via WiFi.

    Cons: ARC seems touchy (might be my older TV), I wonder whether I will need more than one HDCP 2.2 input in the future (this receiver only has one compliant input), I've read the 2014 model won't be able to support the latest DTS codec when it is released (hardware issue not surmountable via firmware update). Note: there is not much Atmos content at this time. To hear the lossless codecs you need to playing Blue Ray discs - streaming TV is still lossy, apparently.

    OK, not fabulous.

    Crutchfield Customer Review (What's this?)

    Bought TX-NR636 in Feb 2015. Really needed a phono input and Onkyo is one of few to offer it. Also has several other features often missing from units in this price range, notably HDMI 2.0, WiFi, and Bluetooth. The sale price pushed me to decide on the 636 vs the 737 (737 has same features and higher wattage, but double the price). My giving only three stars is due to two things: low wattage (95) and a lame remote. I wish that sales where more common on higher end units vs lower end units. Paying the price for a 636 is an easy decision (among competitors) if that's your budget. But I would have liked to put another couple of hundred toward more wattage. To my ear, getting past the 100 watt mark makes a big difference in the sound. However, as noted above, Onkyo's price at the next level unit is at the higher end, or double my sale price on the 636. Why not also discount other units? It makes me question whether HIFI sales are meant to offer an incentive that pulls in new long-term customers, or to dump low performing models...well, actually, I think that I know the answer. So, the TX-NR636 retains 3 stars. IMO the best unit in this price range if you need phono, HDMI 2, WiFi, or some other upgrades, but not enough wattage for solid sound and a 20th century remote. For example, my Harmony One remote can't seem to correctly learn the Onkyo 636 IR language. Something weird there. Works perfectly on all my other AV equipment, but now I need to ALSO use my Onkyo remote.

    Pros: Good feature set for the price.

    Cons: 95 watts is too low for the sound I was hoping to have. Remote unit and (I think) Onkyo's IR language set are underwhelming.

    Wow! You definitely get more than what you pay for!

    Crutchfield Customer Review (What's this?)

    I recently decided to upgrade my receiver to give the punch my speakers deserve. I had a Yamaha RX-V375 that had great sound, all of the HDMI hookups and modern touches, but it lacked the power. 80 watts RMS. I have 2 Klipsch RB-62s, RC-42 center, 2 RS-52s and a KSW-12 sub. The TV is an LG 48" 1080p, and 240 refresh. The RBs can handle 400 watts, which are bi-amp speakers and I did hook them up that way thanks to the receiver, and the others up to 300 and 200 watts respectively. The sub puts out 350. After changing out the receivers and updating the software via Ethernet or wifi, and going through the sound calibration, which by the way is much better than the Yamahas, I was blown away by the sound. Clarity, power, punch and crispness. The speakers were alive! Even with my oddly shaped living room. The picture quality with its up conversion made a significant difference to a trained eye, I have AT&T Uverse that puts out 1080i (ugh), and converted it to 1080p. The Bluetooth connection works flawlessly as well as the Internet connection. My other connections, Apple TV, Bluray player, Xbox and a Wii. All are perfect. I highly recommend this product to someone that wants that extra little punch, quality and modern tech that will last a decade, thanks to 4k tech and free software updates. And of course, thank you Crutchfield. The online compare charts, great price and fast 3 day shipping! Good job ONKYO and Crutchfield.

    Pros: Sound, picture, connectivity via Bluetooth and wifi.

    Cons: Wire connections are really close together. Remote takes some getting used to.

    Crutchfield Customer Review (What's this?)

    Must start with a "shout out" to my product advisor at Crutchfield. When I called with questions about another product, he accessed my purchase history and noted that I had recently purchased a 4K TV. He quickly noted that this was one of the few receivers that is compliant with the new 4K copy protection scheme (HDCP 2.2) which means that it will handle 4K content if it ever becomes available! So going to Crutchfield for one stop shopping is like choosing one pharmacy to coordinate all your prescriptions - a good idea. The unit also has Dolby Atmos capability via a firmware upgrade (easily accomplished) if we ever get decent films using Dolby Atmos. But the unit also has a phono amp so it pays attention to the past as well as the future. And its not so long ago that Onkyo pioneered Internet, bluetooth, and PC connectivity - I've used all so far and they work. Note that you do have four choices with tradeoffs that must be made in a 7.2 setup. First, you can use the extra two channels in a 7.2 system; second, you can send sound to a second zone but this will disable the two extra channels in the main zone; third, you can biamp your front speakers; and fourth, you can use the two channels for Dolby atmos if you add two speakers that fire up or are mounted in your ceiling. I'll choose this fourth option if we ever get decent Dolby atmos content. I would choose one of the more expensive Onkyos in this series for multi-zone if I were interested in that feature.

    Pros: Features. Future proof. Bluetooth. DACs for high-rez audio and USB playback.

    Cons: Manuals need to be written in English for this market. Setup pretty useless aside from speaker calibration which seems accurate though basic. Protection mode kicks in at relatively low volumes, esp. when using Bluetooth or an Internet program source.

    So far it's exactly what I needed.

    Pros: Updated with HDMI 2.0, Dolby Atmos, Great Sound, easy setup

    Cons: Remote Control can be confusing

    On second impression - AWESOME!

    Written by: Wallyman from Washington on February 14, 2015

    Crutchfield Customer Review (What's this?)

    This is an awesome Receiver-awesome sound, features, and affordability. Not awesome-the set up process. If you have a matched speaker set and an optimal listening environment-cool-if not, you may struggle to get the most out of your speakers with the 636-but stick with it. The results are well worth it. After using the AccuEQ Room Calibration on the 636 there wasn't ANY low end signal being fed to my sub-even when I cranked the volume knob on the sub's internal amp to full! I did a factory reset, firmware update and tried AccuEQ Room Calibration again. Same result. I even (gasp!) read the directions in the manual-twice! Eventually I manually set the front speakers removing the crossover points and setting the gain to 0. Then I found a setting called "Double Bass". Once I clicked on this, Amazing things happened. Real low end came pouring out of my sub! The manual says that "Double Bass" duplicates all the low end content from the mains and center and sends it to the sub too. My mains are a really nice set of old school KLH's with 12 woofers. I think maybe the AccuEQ Room Calibration thought I had enough bass already and decided not to send anything to the sub. Recently, Onkyo had some overheating issues in the 636. I understand these issues have been addressed. I haven't fully tested all of the other features like Bluetooth and internet radio playback. But my first impressions-make that my second impressions-are fantastic! And Crutchfield is clearly the place to buy it!

    Pros: The feature set/price point can't be matched. HDCP 2.2 inclusion. I highly recommend the Onkyo 626.

    Cons: If I could add one thing to the 636 it would be old school pre out/main in RCA's so I could insert my graphic EQ. This seems to be a thing of the past. But for me an EQ is almost a necessity. I found a decent work around - for music playback at least. If you use a computer playing your music through iTunes, there's a built-in software EQ in iTunes. Not as handy as a true graphic EQ with sliders but it does the trick. For audio from any other source you only have Bass and Treble controls.

    Crutchfield Customer Review (What's this?)

    After my 2 year old Onkyo tx-nr509 lost audio. Onkyo offered to either repair or trade in the receiver on a new Onkyo receiver. I chose to trade it in on the Onkyo tx-nr636 and am glad I did. The 636 has much cleaner power with better surround sound separation. And that is with just 5.1, I have yet to try the 7.1 since I will need 2 more Polk surround speakers. The atmos feature is another feature I am looking forward to trying out. I have it connected to the Internet via Wi-Fi. I have not used Bluetooth yet but will soon.

    Pros: Plenty of power, packed with features of a much more expensive receiver.

    Cons: Remote control is confusing to use.

    Crutchfield Customer Review (What's this?)

    I wanted to replace my 9 year old Yamaha RXV666 receiver. I spoke with Kramer of Crutchfield to review what current specs and features to look for. He was very helpful. I intended to buy another Yamaha but I wanted features like HDMI 2.0 and HDCP 2.2 for the future. After some research I decided on the Onkyo NR636. I hooked it up to my Samsung 55" HDTV, my Verizon Fios cable box/DVR, Apple TV, and Samsung Blu Ray Player. I use Boston Acoustic bookshelf speakers and use Polk center, surround sound and subwoofer. Set up was straight forward and pretty easy. I admit I did read the basic start up manual but also reviewed the main, more detailed manual, that Onkyo has on line. Everything worked as I hoped for. I was surprised and very pleased with the audio quality for my music. Better and fuller sound that my old Yamaha. The video picture, both from cable and Blu Ray, were outstanding. I am very pleased with this purchase and really feel it offers a great value with all the features it provides for the price. I also was very satisfied with the over all Crutchfield experience. Knowledgable advice, easy ordering and quick deliver. (ordered Thursday AM and received it the next day in the afternoon!)

    Pros: Great features, HDMI 2.0 and HDCP 2.2 for 4k video. Very good sound quality and depth, with excellent video transmission. Very simple to operate.

    Cons: As others have mentioned, no back lighted keypad on remote. Front panel has very small print over it's control functions. These are minor points compared to the over all ease of set up and performance vs. value.

    Item was delivered in 2 days. Sounds great. Some of the components I was connecting were older technology.Directions for setting up were confusing after 2 days I called Onkyo service and it took 2 hours on the phone to get everything connected. I will say the person from Onkyo was very patient and helpful. Remote is cluttered and difficult to read some of the buttons. The display on the front of the receiver is also hard to read, need a flashlight to see the words. Once set up the unit sounds great and all connected components work fine. Would like to have been able to directly set up zone 2 speakers without having to sacrifice the two height speakers when zone 2 is playing

    Pros: Great sound and picture upconverting to HDMI

    Cons: Crowded remote Front panel difficult to read

    Great RCVR

    Written by: CR from Marlton, New Jersey on January 20, 2015

    New Speakers are next on list. Right now using with... Samsung Smart TV Sony CD Player Onkyo DVD Player Audio Technica Turntable X Box Apple and Blackberry phones

    All items listed work great. Set up is fairly easy. Make sure everything is connected before powering up. I use a LAN cable from router to RCVR but you can enter your code for WiFi during set up

    My Cable Box is RCA into RCVR than I have HDMI cable out to TV

    The ARC feature works great. So content from TV can generate back though the RCVR. I called Onkyo help line and turning on this feature was so simple (TV has to have a ARC port, HDMI port 2 is ARC on my TV or you will have to purchase an Optical cable). As well I then downloaded the complete manual form Onkyo online. (instructions there) I think volume gets a little diminished when watching content from TV to RCVR (ie, netflix). Maybe its me... idk, still learning all the ins and outs of this unit.

    For the Turntable to sound clear I had to turn off the Turntables preamp (preamp on/off sw) as the RCVR has one built in. Now Page, Beck and Blackmore sound clear and amazing!!! from my vinyl...:)





    Do yourselves a favor and download the complete manual.

    Honestly I thought the Marrantz and Pioneer Elite I looked into had a richer/fuller sound but this RCVR has more features and more inputs (RCA and HDMI). I'm sure the Onkyo NR838 is more full in sound but for few less watts output and several hundred bucks less this RCVR ROCKS.

    Pros: Features ports, ports, ports Price Sound WiFi, Bluetooth Ability to enjoy new technology and old tech too !!!

    Cons: Miss the switched outlet, my old RCVR had one Would like a little more adjusting of sound levels, bass, treble, mid range...etc

    This was an upgrade from an Onkyo TX-NR503 that I've had for about 10 years. I have to say, while I did expect an increase in sound quality, I didn't expect it to be that noticeable. Well, it's pretty much night and day difference if sound quality. Very crisp, very accurate sound reproduction, more than enough power to fill large rooms. For the price and options on this reciever, nothing really comes close.

    Pros: *Bluetooth *Wifi *Dolby ATMOS *Every streaming music service you need *Supports 4K/60Hz + HDCP 2.2 (HDMI 2.0)

    Cons: *No backlit remote *That's about it.....

    Crutchfield Customer Review (What's this?)

    Easy out of the box set-up for the basics. I haven't tried any of the other special hook-ups - I pod, turn table, lap top, and so on yet. Found the lack of back lighting on remote to be an issue when trying to make adjustments while watching a movie in low room light. Picture feeding from the DirecTV box through the receiver to the TV was not as sharp I though it could be, even after making some manual adjustments to the TV picture parameters.

    Pros: Easy set-up, good quality sound, well balanced sound distribution through the speakers, handled one powered and one unpowered sub-woofer quite well.

    Cons: Remote is not back lit, Instruction manual leaves a lot to be desired as it relates to details, if you have to do anything to the speaker wires, you always have to remove the HDMI cables first because there is not enough space to reconnect the wires if you feed them thru the sides of the wire nuts. AM antenna doesn't bring in much very clearly, even the local station that is only about 7 miles away. FM antenna is much better, but not so much for stations below 95.1.

    Selected for the Phono Option!

    Written by: RecordLover from Detroit, Michigan on January 19, 2015

    Disclaimer - I am not a trained audio guy. Just a music lover with your average home stereo-theater knowledge. This receiver is exactly what I needed for a flat screen TV, PS4, cable box, & my record player. I'm a lifelong record collector, so I wanted an actual PHONO input for my turntable not just an AUX port to serve the purpose. I added some center-pin Rocket Fish banana clips on the wire going from my vintage Kenwood JL-703 floor speakers (big, heavy & solid wood!). Everything plugged into the TX-NR636 flawlessly. My TV, PS4 & cable box are connected with HDMI cables so it is super tidy and clean behind the shelf. I've still got a ton of open ports which is awesome for future expansion possibilities. What blew me away was how easily I synced both my iMAC and my iPod with the Bluetooth function so I am now rocking all my music through this receiver! For me the tipping point over all the other closely similar receivers (regardless of brand) was the massive number of HDMI ports and for me personally it was seeing a dedicated PHONO button right on front. Again - I'm I vinyl record lover, so that was one of those options that hooked me. TIP: the very 1st time you power the receiver up, make sure your TV is connected. The "manual" is pretty basic, but initial receiver setup is not impossible for an average Joe as long as you read and follow the On-Screen instructions. Oh, and have a perfectly quite room for initial speaker/sound field setup & you'll be fine. Happy Rocking! \m/

    Pros: Ease of setup, variety of HDMI ports, bluetooth sync, and PHONO input!

    Cons: User Manual is pretty basic.

    Crutchfield Customer Review (What's this?)

    This receiver is better in every way than I expected it to be. Setting it up is very straightforward, you can get all your remotes to satisfactory be replaced by the Onkyo one. The output video quality improvement in movies is very real, both streaming and DVDs when compared to significantly older Sony receiver with the same home setup. You can get an application that easily doubles as a remote for the receiver. The audio output quality and power is well above sufficient for what I anticipated. Overall very impressed, I hope it impresses me further with the years of service I will get out of it.

    Pros: excellent audio and video output many inputs and outputs easy setup hardware buttons for most functions- you can use it without remote if need be somewhat future proof for 'Athmos' and 4K upgrade feature Android app

    Cons: somewhat outdated screen The manual is unclear at number of places and it takes some interpretation

    Crutchfield Customer Review (What's this?)

    I researched receivers to death before I purchased this one. There were some reviews on another site that gave me some concerns but I figured with the excellent return policy at Crutchfield I would pull the trigger. I'm glad I did. With a firmware update I was able to unlock the full potential of this machine. I upgraded from an older yamaha receiver that was running a bose accoustimass 6 system. After I performed the EQ test with the included microphone I was blown away. Night and day. I've since upgraded to some nice polk bookshelf speakers, a klipsch center speaker, and polk bipole surrounds and this thing rocks. I'm currently running a [offsiteUrl] setup and it's deafening at times. Shakes the house when a helicopter passes overhead. I'm falling back in love with movies that I haven't watched in years. The bluetooth function works like a charm. Everything was easy to setup and any questions that I had were answered in the manual and the advanced online manual. The network function hooked up immediately. I haven't really utilized any functions except for the bluetooth and the surround functions. I should also mention that I route all of my hdmi inputs through the receiver now and there is a passthrough function that is perfect for some members of my family that aren't as "savvy" as I am. This way they don't even have to turn on the receiver to watch the cable box. This receiver is everything that I wanted and more. Chose over a pioneer and sony cuz of atmos

    Pros: Bluetooth, Dolby Atmos, Wireless, 7.2

    Cons: Non that I can think of. It is a little big but it doesn't really bother me. There is a lot "under the hood" so it makes sense.

This one was easy to set up and the sound is great! I love the wifi and bluetooth features. My only negative is that I have a smart tv and the smart hub side doesn't get sound through the receiver. In doing some research it seems like you need to hook this up via optical to get it to work. Seems very impractical and we are not destroying our wall or running another cord from the tv to receiver. We will just use Roku :(

    Only had the product for a short time, but it sounds great with my speaker system and does a good job with the other components in my system. Love it.

    Pros: Great sound and video quality. More than enough connectivity for my needs.

    Cons: As with most other A/V receivers on the market, there are a lot of connections in a relatively small area on the back of the unit, making it hard to get to some of the connections, like the speaker binding posts. Minor, I know but it was my only concern to date.

    Crutchfield Customer Review (What's this?)

    Purchased a 4k television only to discover my 8 year old receiver wasn't allowing me to access all it's functions. Did my research on receivers that are compatible with ultra high def (4K) televisions and decided on this one. It does everything you need it to do and more. Set up was a breeze for ARC hookup and wi-fi set up. Has phono output, 2nd zone and dual sub outputs if you need it. Great price for a great piece of equipment.

    Pros: Price. Versatility. Ease of set up.

    Cons: None that I can think of.

    Do not buy

    I do not usually give such low ratings but this product deserves it. Video output cuts out spontaneously in DVD mode! I switched cables, tv's, DVD players and it still will randomly occur. Will happen 15 minutes or sometimes after 1-2 hours. Audio is fine. It occurred while under warranty so I was able to get another receiver and it still occurred! Geek squad hooks it up for 10 minutes states they can't reproduce the problem and says there is nothing they can do. I did the firmware update and it still happens. I have given up watching DVDs or Netflix with this device! I believe the problem is in the video upconverter but who knows! I will set up the Video directly from my DVD player to TV now but why should I pay extra money for a receiver with an HDMI output that doesn't work!

    Pros: Audio is good

    Cons: Good luck finishing a movie when the video cuts out!

    First Onkyo I've owned and I am impressed! Always heard good things about Onkyo so I decided to try them, after lighting hit by my house disabling my older Yamaha. The set up guide was easy to use and I was up and running in no time. The Dolby Atmos sound is Great, matched up with my new Energy TK-CLASSI-5-1 home theater surround system! One might think that you're sitting in a movie theater. This system is Perfect for my home theater setup. Getting up online either wired or wirelessly is a Plus and thru DLNA I can stream all my music from my computer, it's a nice touch. I am pleased with the savings from Crutchfield also!

    Pros: Easy setup for GREAT sound!

    Cons:

    This receiver does everything I wanted and it does it easily.

    Pros: Easy, quick setup and intuitive configurationization. (my new word) My wife likes the "pass-thru" feature so that she can easily watch TV without dealing with the receiver.

    Cons:

    Almost good enough

    Written by: Pete D from Norfolk,VA on August 16, 2014

    Crutchfield Customer Review (What's this?)

    The unit was received in good condition and was easy to install. All screen menus were easy to follow and all peripherals worked (have not hooked up the turntable but plan to shortly) Power is decent and clear - paired with Energy Take Classic 5.1 speakers. so good sound and depth as expected. The biggest gripe is that the FM rec5eption is very weak below 95 FM. did not matter where i put the wire or the unit. Noticed that in the specs the FM antenna detail was missing. Very disappointing. Will try a powered FM antenna and if that does not work, it will go back.

    Pros: Clean sound, capable of accepting a turntable, good network connectivity. Remote decent

    Cons: Included FM antenna is worthless and does not find channels below 95fm. And the idea of having to buy an externally powered antenna is disappointing at best.

    Great Receiver!!!

    This is very high performance receiver. Installation and the initial setup is nicely explained and user friendly. For best results, I would recommend it to be connected with Bose Acoustimass 10 Home Theater System.

    Pros: Easy Installation User Friendly Operation High Performance Audio/Video output

    Cons: None

    Crutchfield Customer Review (What's this?)

    Purchased this for my brother, whom is not into all the new things electronically, but after we hooked it up, we were both smiling when watching a 3D movie, with the sound cranking, I was pleased to have given him this as a gift. He probably will not take advantage of the streaming and IPOD/USB, but is proud of the way, he can enjoy TV, movies, music in surround sound. I only rated it 4 stars, because when watching the 3D movie, I had it cranked to the max volume the entire movie, now, it could be his cheap, onkyo speakers. They sounded good and loud, but I thought max volume was a bit concerning? I do not regret my purchase and believe most average or better folks who appreciate movie theatre sound will also like/love this receiver. My brother is happy with his speakers and sound, therefore, so am I.

    Pros: Easy to hook up and get acquainted with how to use, sounded really good!

    Cons: No operator manual, had to call Crutchfield for simple advice, but got excellent service and answers to questions in seconds, which got me on my way to setting the receiver up, and enjoying.

    Works as advertised but a little hard to program. I haven't tried to add a internet station yet.

    Pros: Good sound & remote does control all my equipment.

    Great for Android users

    Written by: Scott from Raleigh, NC on July 6, 2014

    Crutchfield Customer Review (What's this?)

    Great so far! I upgraded from my ~10 year old Sony 5.1 receiver, which couldn't decode DD+ and didn't have HDMI. I chose Onkyo over the other ~$500 receivers because of the great android support.

    I currently use the receiver in 5.1 + 2 speakers in zone 2 and it works very well besides some small issues noted below. I have a projector as my main output and not had a chance to see how the 2nd HDMI output works, but I'll update my review (if Crutchfield will let me) when I do.

    Pros: Great streaming audio files from my phone or tablet to the speakers in my living room or zone 2. More HMDI ports than competing models, although switching from one to another is a tad on the slow side.

    Cons: 2 band fix frequency bass/treble control. My 10 year old Sony had a 3 band EQ and you could adjust the freq of each band, which let me really tweak the overall sound for my speakers. The bass/treble adjustments, to me, don't sound good. Onkyo's AccuEQ only sets the crossover frequency and speaker distance, it doesn't actually create a 12 band EQ for your room, like Onkyo's higher end "Intregra" receivers.

    Audio Features

    7 Channel Amplifier: The Onkyo TX-NR636 AV receiver features a 7-channel amplifier rated at 95 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). The AV receiver's amplifier employs WRAT, 3-Stage Inverted Darlington Circuitry, H.C.P.S, and Optimum Gain Volume Circuitry for dynamic, detailed, clear sound.

    • WRAT (Wide Range Amplifier Technology): WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. A "closed ground-loop circuit" design is employed, in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers to immediately cancel the speakers' reflex energy and instantaneously send out the next signal. The same high current better manages speaker impedance fluctuations, which can negatively affect performance.
    • 3-Stage Inverted Darlington Circuitry: The AV receiver incorporates 3-Stage Inverted Darlington Circuitry into the front & center channels. This core Onkyo technology employs a low-NFB (negative feedback) design that makes the sound more natural.
    • H.C.P.S. (High Current Power Supply): Under the anti-resonant cover of any Onkyo receiver, you'll instantly notice the High Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power supply design and high-capacity filter capacitors, it delivers the large amounts of power necessary for reproducing the wide dynamics of movie soundtracks and the detail and clarity of your music.
    • Optimum Gain Volume Circuitry: Optimum Gain Volume Circuitry adjusts the gain so that less than half the amount of attenuation is needed, ensuring the signal never comes close to the noise floor. This protects the signal against noise, resulting in a dramatically clearer sound.

    Amplifier Assignment: The 7-channel amplifier can be configured in a variety of ways to match your type of speaker setup.

    • Normal (7.2ch): The Onkyo TX-NR636 provides 7.2ch surround in your main listening area. You can choose either Surround Back or Front Height speakers (but not both).
    • Front Bi-Amp (5.2ch): The Surround-Back/Front-High speaker terminals can be reassigned and used along with the Front terminals to bi-amp the front speakers, providing improved bass & treble performance. When bi-amping the front speakers the receiver is limited to a 5.2ch speaker system in the main room (no Surround Back or Front Height speakers)
    • Powered Zone 2 (7.2ch + Zone 2): In this configuration, you can connect Front, Center, Surround, Surround Back (or Front Height), and Zone 2 speakers to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back (or front height) channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power.
    • Dolby Atmos (w/ Firmware Update): The Surround-Back/Front-High speaker terminals are assigned to power a pair of overhead ceiling speakers or a pair of Dolby Atmos-enabled speakers to create 5.2.2ch Dolby Atmos surround sound. Zone 2 speaker can still be powered by the receiver in the configuration. When Zone 2 is off, all seven channels will be used in the Main Zone for Dolby Atmos. However, when Zone 2 is on, power to the Dolby Atmos channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power without Dolby Atmos.

    192kHz/24-bit DACs + 32-Bit DSP Processing: This Onkyo TX-NR636 is equipped with 192kHz/24-bit Burr-Brown DACs to decode and playback high-resolution recordings with less jitter and  clearer sound. The receiver also employs a powerful and highly accurate 32-bit processing DSP (Digital Signal Processor) for better surround sound reproduction.

    AccuEQ Room Calibration: Calibrating the sound to suit your room's acoustics is simple with Onkyo's AccuEQ auto-room calibration. Once you've connected your speakers, plug-in the included mic and wait a few moments as the TX-NR636 measures things such as speaker distance, type, crossover, and output, taking into account any reflections from your walls and floor. The system is designed specifically to by-pass your front left and right speakers. The system then optimizes the frequency response of the remaining speakers so you can enjoy balanced surround sound regardless of room shape or furnishing while retaining the characteristics of your front left and right speakers for optimum enjoyment

    Multi-Channel Decoding Formats: The Onkyo TX-NR636 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Dolby Atmos: The TX-NR636 receiver is Dolby Atmos (5.2.2ch) compatible through a firmware update from Onkyo's website. Dolby Atmos combines traditional home theater speaker layouts with either ceiling-mounted speakers or new Dolby Atmos-enabled speakers to create a plane of sound above the listener. The impact of either in-ceiling or Dolby Atmos-enabled speakers is breathtaking. Your room fills with realistic, multidimensional sound that places you directly in the center of the entertainment experience.

    • Ceiling Mounted Speakers: Ceiling speakers are used for maximizing effects in Dolby Atmos listening mode. Install these speakers midway between the position just above the listening position and the position just above the front speakers, or simply install them just above the listening position.
    • Dolby Enabled Speakers: There are two types of Dolby Enabled Speakers; one is to be placed on the top board of other
      speakers such as front speakers and surround speakers; the other is integrated within the front or surround speakers. Dolby Enabled Speakers are designed with their output facing toward the ceiling to create an elevated audio effect in the Dolby Atmos mode by providing sounds echoing off the ceiling.
    Note: Globally, more than 100 cinema blockbusters have been released featuring Dolby Atmos soundtracks in the past two years, and many more are on the way. Major Hollywood studios are partnering with Dolby to create home video versions of both current box office releases and previously released favorites for release starting in 2014.

    Dolby Surround: Dolby Surround offers an enhanced cinema experience to your Dolby Digital (Plus/TrueHD) and DTS (ES/HD) movie soundtracks using your existing 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".

    Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:

    • Orchestra: For classical or operatic music.
    • Unplugged: For acoustic instruments, vocals, and jazz.
    • Studio-Mix: Suitable for rock or pop.
    • TV Logic: Adds realistic acoustics to TV shows.
    • Game: The receiver offers four different Gaming modes - RPG, Action, Rock, and Sports.
    • All Ch Stereo: Stereo sound from all speakers. Ideal for background music.
    • Full Mono: All speakers output the same sound in mono.
    • Theater-Dimensional (T-D): Theater-Dimensional circuitry takes the complexity out of conventional surround-sound setups and lets you experience the excitement of surround sound from as few as two ordinary speakers. Theater-Dimensional's unique multi-speaker modes let you place up to five speakers conveniently by the TV, for the most realistic virtual-surround sound possible.

    Direct Mode: In Direct mode, audio from the input source is output without surround-sound processing. This mode delivers pure sound with minimum sound quality adjustment and filtration.

    Surround Parameters: The Onkyo TX-NR636 lets you tweak and fine tune specific surround sound modes to suit your preference.

    • Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust; Panorama: (broadens the front stereo image to the surround speakers to provide a wraparound effect), Dimension (allows you to move the sound field forward or backward), and Center Width (allows you to adjust the width of the center channel).
    • Center Image: In the Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
    • Pro Logic IIz Height Gain: The Height Gain Control in Dolby Pro Logic IIz enables the listener to select how much gain is applied to the front high speakers. There are three settings, "Low", "Mid" and "High", and the front high speakers are accentuated in that order. While "Mid" is the default listening setting, the listener may adjust the Height Gain Control to their personal preference.
    • Listening Angle: While listening in the Theater Dimensional mode you can adjust the listening angle to either Wide (if listening angle is 40°) or Narrow (if listening angle is 20°).

    Audio Enhancements: The Onkyo TX-NR636 receiver provides various audio enhancements to deliver a high-quality listening experience every time.

    • CinemaFilter: Using the CinemaFilter you soften overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
    • Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz and analog input signals.
    • Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.

    Bass Management: The Onkyo AV receiver offers Tone Control and Phase Matching Bass technology to get the most bass impact out of your system.

    • Tone Controls: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-NR636 from -10 to +10 dB.
    • Phase Matching Bass: Onkyo's Phase-Matching Bass optimizes low frequencies while preserving mid-range clarity. This means that powerful bass plays back with clear vocals; it doesn't overpower them.
    • Double Bass: You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer.

    Volume Setup: The Onkyo AV receiver provides the following volume settings.

    • IntelliVolume: With IntelliVolume, you can set the input level for each input (+/-12dB) selector individually. This is useful if one of your source components is louder or quieter than the others. This function does not work in Zone 2.
    • Maximum Volume: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 30-79 (max), or Off (disabled).
    • Power On Volume: Use this feature to set the volume level when the power is turned on. You can choose between Last (same as the volume when the unit was turned off), Min (0), or 1-79.
    • Headphone Level: With this setting, you can specify the headphone volume (+/-12dB) relative to the main volume. This is useful if there's a volume difference between your speakers and your headphones.

    Audio Inputs/Outputs: The Onkyo AV receiver offers a variety of analog and digital audio inputs/outputs.

    • Assignable Digital Inputs: The Onkyo receiver is equipped with one optical digital input and two coaxial digital inputs. All three digital inputs are assignable. You can choose auto decoding , PCM, or DTS for the digital audio inputs. Auto will decode the signal in its original form (Dolby Digital, DTS, PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS formatted sources.
    • Phono Input: The Onkyo AV receiver is fitted with a Phono input and ground terminal for connection of a turntable (MM).
    • Binding-Post Speaker Terminals: There are color-coded binding-post terminals for all speaker connections - Front, Center, Surround, Surround Back/Front Height, and Zone 2. The binding post terminals will accept bare-wire, pin-connectors, and banana plugs (single/dual). Use 6- to 16-ohm speakers.
    • Dual Subwoofer Outputs: The receiver is fitted with two subwoofer outputs to connect dual powered subs for extra bass. The dual outputs share the same input signal and are not discrete.
    • Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.

    Video Features

    7 HDMI Inputs/2 HDMI Outputs: The TX-NR636 has seven assignable HDMI inputs (6 rear/1 front) and two HDMI outputs for connecting Blu-ray/DVD players, Satellite/Cable boxes, Game Consoles, and other video components to your TV. The dual HDMI outputs can simultaneously output the same audio/video signal to two TVs (video is output at the resolution supported by both TVs). The HDMI jacks can accept and switch 480i, 480p, 720p, 1080i, 1080p, or 4K video signals to a HDTV (depending on input/output). All HDMI jacks will also support uncompressed standard or high definition digital video along with the following audio signals; 2-channel linear PCM, Multichannel linear PCM (up to 7.1ch), and Bitstream (Dolby Digital/DTS, etc.). Additional HDMI features include -

    • 4K/60Hz + HDCP 2.2 (HDMI 2.0): The TX-NR636's HDMI 3 input and main HDMI output are version 2.0 compliant; supporting 4K/60Hz video signal, 21:9 display format, and HDCP 2.2 DRM copy protection compatibility. By implementing these new HDMI technologies, the TX-NR636 will be able to support future 4K streaming content from internet service providers (like Netflix) and UHD terrestrial/satellite broadcasts (not yet available). The AV receiver's HDMI 2-4 inputs are also version 2.0 and support 4K/60Hz video signal, but do not support HDCP 2.2 DRM copy protection. The receiver's HDMI 5-7 inputs and sub HDMI output are version 1.4 and support up to 1080p video.
    • 3D-Ready: All HDMI jacks will accept 3D video from your 3D-ready Blu-ray player and output the video signal in 3D to your 3D-ready flat-panel television.
    • ARC (Audio Return Channel): The receiver's main HDMI output features ARC (Audio Return Channel). This feature allows audio to be sent from your compatible HDTV to your receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television. The sub HDMI monitor output does not support this feature.
    • Auto Lip-Sync: The Lip-Sync function can automatically synchronize HDMI audio and video (for any HDMI jack) that has gotten out of sync due to the complex digital video processing being performed by your HDMI-compatible TV. With HDMI Lip-Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the AV receiver. You can also manually correct the audio delay from 0 (no delay) to 400 milliseconds; in 10 millisecond steps.

    Marvel Qdeo Video Chip for 4K Upscaling: The Onkyo TX-NR636 utilizes a Marvel Qdeo Video Chip for 4K upscaling and video processing. The Marvel Qdeo Video Chip produces quiet and natural video, free from noise and artifacts. Analog component/composite video signals are converted to HDMI, so you only need one cable to connect the receiver to your TV. 480i video from the receiver's component/composite video inputs and any HDMI video signal can be scaled to a higher resolution set in the menu. You can set the AV receiver to upscale analog and HDMI video to 480p, 720p, 1080i, 1080p, 4K, Auto (automatically scaled to the highest resolution supported by the display), or Through (no scaling). Upconversion and upscaling is only supported by the main HDMI video output.

    MHL-Compatible HDMI Port: The front-panel HDMI input is MHL compatible. This MHL compatible HDMI port provides easy, direct connection of MHL compatible Android smartphones. Playback of up to 1080p video and multi-channel audio from the phone is supported. The receiver will also charge your connected phone. Play, Stop, and other basic operations can be controlled from the AV receiver's remote control. Check here for a list of compatible MHL-enabled Android phones.

    Note: The front-panel HDMI input, along with the receiver's front-panel USB port can also be used to connect your Lightning or 30-pin connector Apple iOS device via Apple's Lightning Digital AV adapter or 30-pin digital AV adapter; you'll also need the USB cable that came with your Apple iOS device, and a HDMI cable (sold separately). This type of connection provides "screen mirroring", audio/video playback, and charging of your Apple iOS device through the Onkyo receiver and your HDMI-connected TV. All control of your Apple iOS device will be done through its own touchscreen (not the receiver). See AV adapter links for specific Apple iOS compatibility.

    HDMI Through: When enabling the HDMI Through function, regardless of whether the AV receiver is "on" or in "standby" both audio and video streams from an HDMI input will be output to your television, via the receiver HDMI monitor output. You can select between 3 HDMI Through functions modes.

    • Auto: Detects the signal and automatically selects the input sources.
    • Source: Selects the input source (BD/DVD, VCR/DVR, CBL/SAT, Game, PC, Aux, TV/CD, Port) for which the HDMI Through function in enabled.
    • Last: The HDMI Through function is activated on the input source selected at the time of setting the AV receiver to the "standby" mode.

    InstaPrevue: InstaPrevue technology provides a live video thumbnail of the available content on your devices connected to the receiver via HDMI. As a result, you can preview audio/video streams coming from up to five HDMI inputs previously assigned to input selectors on your HDMI connected TV. Even with multiple components connected to receiver through HDMI, you can easily switch between inputs as their previews are displayed on a single screen on your television. You can even use the InstaPrevue feature for Picture-in-Picture. You can specify the number of preview thumbnails, as well as their positioning on-screen.

    Note: If no video signal are present, the thumbnails will be filled in black. With 3D video signals, the image may not be properly rendered on the preview thumbnails of InstaPrevue.

    Analog Video Inputs: The receiver features three composite video inputs and one composite video monitor output which support 480i video signals only. There is one component video input and one component video output which support up to 1080i video signal. You must connect the receiver to your TV via composite and/or component video to view incoming video from the receiver's composite/component inputs.

    Picture Adjust: Using the Picture Adjust feature, you can adjust the picture quality and reduce any noise appearing on your TV screen.

    • Wide Mode: Auto, Full, Zoom, Wide Zoom, or 4:3.
    • Picture Mode: Custom (Brightness/Contrast/Hue/Saturation/Color Temp), Cinema (for movies), Game (for gaming), Through (changes resolution), Direct (no adjustment).

    Convenience Features

    On-Screen Menu w/ Setup Assistance: The Onkyo AV receiver offers an on-screen (GUI) menu system through its HDMI output. The simple on-screen display combines text and graphics that make setup and other operations extremely easy. The initial setup assistant takes you step-by-step through speaker configuration, source connection, remote programming, and network connection. If your TV is connected to the composite video or component video monitor output, you will need to use the AV receiver's front-panel display when changing settings.

    Dual-Zone: In addition to the main listening room, you can also enjoy audio playback from a different source in another room of your home using the receiver's Dual-Zone function (Zone 2). The receiver features Zone 2 line-outputs, as well as Zone 2 speaker terminals. By using the line-level outputs on the TX-NR636 you can connect an external receiver or integrated amplifier in a second room, allowing you to listen to 7.1ch surround in the main room and play a different audio source in another room of your home. By using the speaker-level outputs on the TX-NR636, you can directly connect a secondary pair of speakers in another room of your home, allowing you to listen to 5.1ch surround sound in your main room and play a different audio source in the other room. The volume of Zone 2 is controlled from the receiver when using the speaker outputs and from your add-on integrated amp when using the line-level outputs.

    • Compatible Zone Sources: Only Tuner, analog, USB, Network, and Bluetooth audio sources can be sent to Zone 2.
    • Incompatible Zone Sources: Optical/coaxial digital and HDMI audio sources are not output to Zone 2. You cannot output any video signal to Zone 2.
    Note: As for Network, USB, and Bluetooth sources; you cannot select different inputs for the main room and Zone 2. For example, if a Network source been selected in the main room and then a USB is selected as playback source in Zone 2, the input in the main room will also change to the USB source. When listening to AM/FM radio, you cannot select different stations for the main room and Zone 2.

    Name Edit: You can enter a custom name for each individual input selector and radio preset for easy identification. When entered, the custom name will appear on the display. This function cannot be used for the AM/FM, Network, USB, and Bluetooth input selectors.

    Customer Q&A

    34 questions already asked

    Brian, for a low to moderate priced (around $1,000) speaker system, with a lot of great sound, I've been very happy with the following Polk Audio speakers and my TX-NR636. Polk TSi400 front towers, Polk TSi CS10 Center channel, Polk TSi 100 rear surrounds on Sanus NF30 stands, Polk RC60i in ceiling speakers, and a Polk PSW108 Subwoofer. My front floor standing speakers are approx. 8' apart, rear surrounds are just slightly to the rear of the listening area approx. 12' apart, and the ceiling speakers are just above the listening area approx. 8' apart. I also found it best to manually set the "speaker level calibrations", in the speaker setup of the receiver, to adjust levels of each speaker for your preference. Hope this helps. [ JESSE T  Oct 05, 2015 ]
    I have Bose speakers and in a typical surround sound placement. [ TOM  Oct 05, 2015 ]
    I used jl audio in wall speakers and jl ceiling speakers. The sound awesome [ Matt  Oct 05, 2015 ]
    IM using Polk audio tower speakers all around with Polk subs. Ceiling best for atmos [ ANTHONY  Oct 05, 2015 ]
    I am using 5 speaker system. 1 center, 2 front and 2 surround which are placed up and behind the listeners. I like the way it sounds, hope this helps. [ TOM  Oct 05, 2015 ]
    I placed my two ceiling speakers directly over the couch. [ Matt  Oct 05, 2015 ]
    You know that is a good question - I have never been interested in Sirius radio - but then if I ever do have an interest - hmmm? I really have no idea - try and find it for free is my suggestion on the internet? [ GROVER  Jun 29, 2015 ]
    It is not free. I have a xm account for my car. For $4 per month I upgraded it to include an Internet account. I stream that through the onkyo. [ KENNETH  Jun 29, 2015 ]
    Not free, google Sirius XM radio fees. [ MICHAEL  Jun 28, 2015 ]
    I believe it is only an app to access a paid subscription. It you do not have a subscription with the (extra) internet add on then there is no access. [ SCOTT  Jun 28, 2015 ]
    No [ Douglas  Jun 28, 2015 ]
    Gary, Only if all of your peripherals will work with it. i.e. speakers. It's component based. I love it [ ERIC M  Jun 27, 2015 ]
    yes [ ANTHONY  Jun 22, 2015 ]
    Darren, The short answer is yes, the main power draw is the sub and you have that covered with the powered Polk. Front, mid and center speakers are close to viewer as compared to the rears. The rears are important as well, especially if you watch sports and action movies. We found that with our 7.1 setup the auto balance feature doesn't work well in all situations. So manual setup is required and that is very easy. Hope this helps. John [ JOHN  Jun 20, 2015 ]
    Yes they can go through the HDMI digital connection. I had an issue with the sound so added an optical cable. I since have been told there are single and dual directional HDMI cables and I may have a single directional cable [ MICHAEL  May 18, 2015 ]
    I forwarded your question to an Advisor and they responded with the following: I checked the specs for the KEF Q700 speakers online and they seem like they should match well with the Onkyo receiver. They handle a good amount of wattage and have a pretty decent sensitivity. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  May 19, 2015 ]  Staff
    Easiest way to fix this, add a digital to analog converter, i do this with the same receiver you have [ CEATC  Jun 07, 2015 ]
    You can play internet streams, USB, Bluetooth, and AM/FM plus anything connected via analog inputs in Zone 2. You can't play anything connected to an HDMI or digital input jack. [ P  May 12, 2015 ]
    I Use zone 2 outside. Works good. [ Almon  May 12, 2015 ]
    Yes it does :( [ DENNIS  May 12, 2015 ]
    I forwarded your question to an Advisor and they responded with the following: All great questions. The manufacturers are giving us the 95 watts per channel at their .08% THD; so when listening to just 2 speakers on a stereo source that's how much power you get clean. When you get a 7 channel receiver the power gets divided down but now evenly because when watching a movie the center channel uses the majority of the power and the front left and right and surround left and right only need about 10 watts to reproduce the sound affects coming from them. Making all of this a little more crazy is adding Atmos which basically is 5.2.2; 5 speakers that are 3 in the front and 2 surround, then 2 outputs for subwoofers THEN 2 channels for the Atmos sound but Zone 2 can't be played when this is happening because Zone 2 and the Atmos speakers are using the same output power. The 165 watts at 6 ohms with one channel driven is "bunk". it's a marketing tool to make their amp sound more powerful. All speakers can be 6 ohm Except Zone 2. they need to be 8 ohm per the manufacturer. Will you get more power when using 6 ohms? Yes, but nothing notable so it's not something worth publishing since it become inaudible when you're running home theater. Tower speakers as the front left and right usually do fine as long as they can run off of 50 watts RMS because that's all they'll get when in surround mode. They'll get the full 95 when listening to stereo music. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Apr 07, 2015 ]  Staff
    I strongly disagree with other answerers. The iPhone/iPad app absolutely *does* allow you to control Zone 2. You can switch between Main and Zone 2. I do it all the time. [ smallmountain  May 30, 2015 ]
    No. App is very basic, no controls for 2 [ MICHAEL G  Mar 28, 2015 ]
    Sorry, but I do not have an iPhone or use such - and I have not set up any zone 2 yet - just very happy with zone 1 thank you :) so I know nothing to help this person - sorry again [ GROVER  Mar 28, 2015 ]
    I believe that it did when I first measured to make sure it would fit on my skinny shelf. [ GREGORY  Mar 25, 2015 ]
    It doesn't pull any more power than expected. We have the components spread out over several circuits, and do not notice any power problems when being used. We bought this system this January and have been quite pleased with it. [ PAUL W  Mar 24, 2015 ]
    Hello I'm sorry I can't answer your question. We have our unit plugged into a surge protector, along with the tv, internet modem/router, cable box. Even with all these items, the surge protector is showing 1.0 Hopefully, someone can give you a better answer. Don't know if this gives you an idea but thought I'd add it. [ DARLENE  Mar 24, 2015 ]
    How much power does the unit pull from the wall? I have no clue, other than thats a question that I personally didn't need answered. It will not pull any crazy amount of power, incase you were worried about your electric bill? Make sure area (shelf should be well ventilated) is clear of anything else nothing should be on top because unit needs to vent thru that area [ CHRISTOPHER  Mar 24, 2015 ]
    They will work, but you will not likely be happy with the sound. Money spent on speakers is worth every penny, for the most part you get what you pay for. I would opt for a powered sub ( ~ 200watt) and run a 7.1 system if you have the space. 5.1 is fine as well, the key is to tune the system to your position in the room. You also need to consider the type of listening you plan on, we use our system mainly for movies and sports viewing. [ JOHN  Mar 23, 2015 ]
    I would not suggest that you use these speakers. They are only rated for 60 watt. The receiver will put out way more power, so you will likely blow them. [ Jess  Mar 23, 2015 ]
    Yes it is 4k compatible, that's why I bought this unit over a Bose system. [ KENNY  Mar 10, 2015 ]
    No but there is a zone 2 selection for listening in a second room. [ DAVID  Mar 05, 2015 ]
    Yes [ DAN G  Mar 04, 2015 ]
    It has a zone 2 option which allows for a second pair of stereo speakers. [ PATRICK  Mar 04, 2015 ]
    Technically no. It does have two separate zones that you can control independently. [ CHARLES  Mar 04, 2015 ]
    If you are referring to a "B" speaker switch, then no it does not. It has a separate zone for additional speakers. [ William  Mar 04, 2015 ]
    You can turn it up on the initial set up and my sub has a volume control on the speaker also . On the bluetooth ? I am more of a movie and TV man dont have mine hooked up bluetooth. [ BRYAN  Feb 26, 2015 ]
    The only way I can turn the sub volume up is with a knob on the side of it - at any volume - I know of no way to remotely do it - but I am not real good at remotes. There are LOTS of buttons on the remote? Set the TV sound to go to the receiver (Onkyo) and you can then play anything you want Bluetooth - DVD - CD - by selecting the appropriate button on the Onkyo for it to play - the TV sound will go to the Onyko but it will not be played when you are using it in bluetooth with some other gadget - source - we use and iPhone for iTunes.... probably want to listen to classical music and watch basketball games? Can do. [ GROVER  Feb 26, 2015 ]
    Using Speaker Calibration, you can turn up/down the subwoofer. That said, using auto-calibration works very well. When switched to Bluetooth (or Network), the receiver takes over the TV and shows song information, etc, so you can't have the TV playing on mute while Bluetooth music is playing UNLESS you set it up as Zone 2. However, you would need to have additional speakers connected to Zone 2. [ HEBERTO  Feb 26, 2015 ]
    Figured out the subwoofer problem. Jus need know other question thx [ dj  Feb 25, 2015 ]
    I have had mine for 3 months and have not had any problems. I like my receiver [ JACK  Feb 25, 2015 ]
    Haven't experienced anything of the sort. This receiver has done everything I purchased it for thus far. [ Russell  Feb 23, 2015 ]
    I've owned this for 4 months without issues. I have a small USB fan pulling heat from the back of the unit but honestly, I'm not sure i need it. No issues whatsoever so far.......(knock on wood). Very happy with the product. Using it with the last great Plasma, Samsung 8500 series, Dish Hopper, Apple TV and an Oppo BDP 103 DVD Player Easy to set up, works well. Happy.... [ RICHARD  Feb 23, 2015 ]
    I haven't had a problem, and my daughter runs it all of the time for her Disney movies...admittedly not loud or anything but still pushing sound. [ NIRAV  Feb 22, 2015 ]
    I have not seen this issue with HDMI But all high power receivers heat up. You need proper ventilation or use a small fan. [ EBENEZER  Feb 22, 2015 ]
    Mine has been working great. It's on 24/7 since I bought it in Nov '14. [ MARTIN  Feb 22, 2015 ]
    I can honestly say that I have not experienced either of these issues with mine. Aside from a minor issue with using the ARC with my LG smart TV, the Onkyo has performed well. I only have a Cable DVR and DVD player connected and the HDMI pass thru is a great feature. [ FRANK J  Feb 22, 2015 ]
    I returned two of them for different reasons. I returned one because the WIFI didn't work and the second because it over-heated. Instead, I got ONKYO's TX8050 which is a no-nonsense stereo unit which also has WIFI capability. I am very pleased with this unit. [ FRED  Feb 22, 2015 ]
    I've heard the same thing, but I've been using it daily for about 6 months with no trouble. I too love the features. As a side note, I recently put it in a new cabinet. I noticed it was getting hot in there, so I drilled a few extra ventilation holes in the back (of the cabinet, not the receiver!) and it's been keeping much cooler. [ P  Feb 22, 2015 ]
    My receiver has been in operation for only about 2-months and have not experienced any operational issues...works perfectly so far. [ RICHARD H  Feb 22, 2015 ]
    I forwarded your question to an Advisor and they responded with the following: On the Onkyo TX-NR636 if your source was not recorded in Dolby Atmos format then you'd select the Dolby surround mode on the receiver which would give you a simulated surround sound. Atmos is designed to give you a more enveloping three-dimensional effect, so yes it's a noticeable difference. For example in a movie that a plane is suppose to be flying overhead instead of it coming out of one of the floor speakers, those sounds are sent to the in-ceiling speakers, so it actually sounds like the plane is overhead. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Feb 19, 2015 ]  Staff
    I use my reciever to play music in side my house and outside at two different volumes from one source. So short answer is "YES" [ DAVID A  Feb 10, 2015 ]
    Not sure but believe you can. [ ANTHONY  Feb 10, 2015 ]
    The answer is yes [ MICHAEL  Feb 10, 2015 ]
    Yes, from the same source or from different sources. Note that the volume of each zone is controlled independently, but the equalization is not. [ Nicholas  Feb 10, 2015 ]
    Yes [ Matt  Feb 10, 2015 ]
    I am sorry I can't be of any help but I do not know what a 9.2.4 setup is. I purchased this receiver because the Crutchfield rep I spoke to suggested this unit because it was simple to set up and was affordable. [ KENNY  Jan 26, 2015 ]
    I'd be inclined to say no. If it is possible you could only do it by having a preamp or computer that could do the processing and use the receivers basically as nothing but amps. Even if the primary receiver could pass the unused channels on to another receiver you'd have to remap the extra channels to the l/r front, c, l/r rear on the 2nd receiver. The receiver itself will never decide to play the surround back or any other through the 5 conventional channels. It can only be spoofed by an outside source if at all. Media Player Classic on PC will allow you to reassign channels, although what form its able to output it I don't know. The 2nd hurdle here is that the processor has to put out 2 streams. One for the first 7 channels and first receiver and one for the last 6 channels and completely spoofed onto the 2nd receiver. Hope you find a better answer. [ JASON  Jan 25, 2015 ]
    You will be limited by the range of the Bluetooth standard. In my experience, typical range is about 30 feet unobstructed, 15 feet with walls, maybe less with a floor. [ WENDY  Jan 24, 2015 ]
    It should work if the distance is less than 30 ft or so. Obstacles could decrease range though. [ DAVID  Jan 24, 2015 ]
    Not likely.. You can try it.. I get approx. 30 ft and it starts to break up.. Bluetooth is a poor transport protocol for hi-fi audio to begin with and unpredictable when connecting.. But it works ok when connected and witin range. [ Bryan  Jan 23, 2015 ]
    haven't tried the bluetooth feature, so don't know [ George  Jan 23, 2015 ]
    I have a very large one story home and I can lay in my master bedroom and connect with Bluetooth (which causes the recover to turn on! Super cool) from my phone and play it fine. BT is only about 50 feet or so range but it goes through walls very well. [ Ryan  Jan 23, 2015 ]
    Does not run hot whatsoever. Also, i'm not sure how it would run hot or overheat anyway as it does have a built in cooling fan. Ive only seen the fan kick on once, and I do keep the volume fairly high. [ WENDY  Jan 24, 2015 ]
    I've had this for about a month and haven't had any heat issues. [ DAVID  Jan 24, 2015 ]
    I have not noticed my 636 running hot under normal to loud conditions. However, in my setup I do not have anything on top of my 636 to ensure proper ventilation. Hopefully this helps. Overall I am extremely happy with my 636. [ STEVEN  Jan 23, 2015 ]
    I have not had any issues thus far. However, I have only had mine about two months. [ PATRICK  Jan 23, 2015 ]

    So far, so good. I ran all the speaker wire out, updated to banana tip connectors, and plugged in all my HDMI cables before firing up the receiver for the first time. Initial setup was easy. The sound with just the 4 Kenwoods rocking is amazing. I'll have to get the other 2 wired in and pick up a subwoofer next. Pretty satisfied thus far. [ RecordLover  Jan 18, 2015 ]
    I am not an expert for sure - but yes it would work - I would recommend a separate sub woofer - I also had an old system - we went all in and got new speakers as well - as for handling the many different components - yes it will easily handle that what you asked plus more - but again we are just getting settled in with the new system and loving it - be careful with the mixing - is all I advise - - love our Onkyo! [ GROVER  Jan 18, 2015 ]
    Recomend a sub and Klipsch center channel . Very good unit [ BRYAN  Jan 18, 2015 ]
    This receiver has two subwoofer outputs. Also has phono input. Sony 1050 has no phono input. [ JACK  Jan 18, 2015 ]
    Thanks for the response Jeff, you are correct, they can't be bi-amped. [ Customer  Jan 12, 2015 ]
    The chances are pretty good that bookshelf speakers will not have the ability to be bi-amped. You can find out more about bi-amping in our Labs section here: http://www.crutchfield.com/learn/blogs/av_tips/archive/2008/04/23/are-you-sitting-on-a-wealth-of-untapped-power.aspx?showAll=N You're best bet will probably be to either allow the extra channels to remain dormant, or possibly to use them to power a 2nd zone with audio.

    Sorry, not able to give a solution since I don't use apple product In that mannet. [ Mr.  Jan 22, 2015 ]
    I bought this unit in Nov. 2014 and sync an iPad Air to it to stream music with no problem. [ MADELENE  Jan 15, 2015 ]
    don't have an iphone or apple device [ ELLIOT  Jan 13, 2015 ]
    I was able to connect to it through Bluetooth no problem. I have a(n) 5s [ MR PAUL E  Jan 12, 2015 ]
    Hi - First, I play my iPod through it without a problem via bluetooth. It paired just fine. I have not tried my iPhone or iPad yet, but don't see any reason that they would not work. My mac does not have bluetooth, so I ran a connection from my mac's audio out to the rca post on the back of the 636 (I used the one marked 'pc'. Now I can play any of my iTunes selections. [ JACK  Jan 12, 2015 ]
    I have connected both an iPhone 4 and iPhone 6 via bluetooth without issue. Connecting TV via one of the HDMI inputs would also work for a wider range of devices and from a sounds quality it definitely comes through with more power and clarity that way. [ DANIEL  Jan 12, 2015 ]
    I was able to sync my IPad through bluetooth. [ FRED  Jan 12, 2015 ]
    When I played a CD in Stereo it only used the left, center, right and sub woofer. When I played pandora it used all 7. I'm guessing it depends on the format in use. [ TYLER  Dec 31, 2014 ]
    Yes, it can be set for stereo mode for all 7 speakers . [ Michael  Dec 31, 2014 ]
    Yes. I get sound through all my speakers in certain Dolby modes and the all channel stereo mode. Be sure to use the music optimizer. [ Jess  Dec 31, 2014 ]
    Jason, Yes, there is an "all stereo" sound field mode that works very well for programs that do not broadcast with their original full Dolby soundtrack. This also works really well on music, but there are other modes for music that will enhance the sound through the 7.1 system as well. Hope this helps, J [ JOHN  Dec 31, 2014 ]
    Yes, the Onkyo TX-NR636 has many different listening modes, including All Channel Stereo. A complete list of all listening modes can be found in the "Listening Modes" section of the advanced user manual (page 16). The manual can be found on the onkyo web site. [ DENNIS  Dec 31, 2014 ]
    Yes it will Jason Michael [ MICHAEL  Dec 31, 2014 ]
    No, if you can, change setting to music or dolby, then it will play in all speakers. [ ANTHONY  Dec 31, 2014 ]
    Yes it can play stereo on all speakers. [ PAUL  Dec 31, 2014 ]
    It can only power 7 channels at any given time. So if you have a Zone 1 setup with 7 speakers, then if you activate Zone 2, it will deactivate your surround back/height channels and use that to power Zone two, leaving you with a Zone 1 at 5 channels. [ NIRAV  Dec 20, 2014 ]
    No pre-amp needed, just plug in works fine. [ SCOTT  Dec 15, 2014 ]
    The unit should have the ability to power the 2nd zone without the need of a pre-amp. [ DAVID JAMES  Dec 13, 2014 ]
    Zone 2 works without adding an amp. Note that Zone 2 uses an analog signal and can take some care to set up. I now have mine set up. I have zone two sending a signal to my speakers switcher, which then plays into the kitchen, extra room, and deck. I can play whatever is playing on bluetooth, a cd player, AM/FM, and I have even run a line from my Mac to play iTunes. To do this I connected the rca posts on the back to the cd player, and the mac (and the tv so that I can send out audio and follow something on tv in another spot without actually watching it). The tech guys at Crutchfield are helpful with this kind of thing. All that said, you still can connect a powered amp for zone 2s rca posts if you prefer. [ JACK  Dec 13, 2014 ]
    No pre-amp is required for zone 2. It only plays analog inputs to zone 2 when it is different that the primary zone selections. [ DANIEL  Dec 13, 2014 ]
    Haven't set it up yet. However, I believe so and bought this receiver with that intention. [ GREGORY  Dec 12, 2014 ]
    No pre-amp needed in my solution. Just plug them in, turn Zone 2 on and it works. [ Patrick  Dec 12, 2014 ]
    You do not need a pre-amp and can connect directly to zone 2. However, 5.1 will be the maximum in the main room when the zone is on . [ LISA  Dec 12, 2014 ]
    I have not used the zone 2 feature, however the basic manual that came with the unit shows a direct connection to the stereo speakers in zone 2. This will use 2 of the 7 channels so you can only have 5 in the main room. The second zone input seems to be restricted to only one set of analog inputs and/or a line level pre-amp output which I guess would allow you to have a separate power amp for the other zone. Sorry I couldn't be more help. Onkyo does have the advanced manual available on line which may give you more details. Good luck. [ FRANK J  Dec 12, 2014 ]
    no [ ELLIOT  Dec 12, 2014 ]
    The unit will be used in a house still under construction so it's still in the box. Sorry. [ PHYLLIS  Dec 12, 2014 ]
    Sorry cannot answer this question b/c I do not use zone 2. [ Mr.  Dec 12, 2014 ]
    I haven't used zone 2 but I've read through the manual and I don't see anything that would suggest that it does. [ FRED  Dec 12, 2014 ]
    No, just speakers. The "ready" aspect is because it ships without support, but once you do the free firmware update it's all set. [ Nicholas  Nov 24, 2014 ]
    Whats the resistance of the speakers? You need to get between 6-16ohms total, if you going to drive both speakers from the center channel [ JOHN  Nov 14, 2014 ]
    Can't do it with this receiver. I would use a speaker selector to split it to both speakers then you wont burn out the center channel on the receiver. [ PAUL  Nov 14, 2014 ]
    You would have to tie 2 fronts in to same channell [ ANTHONY  Nov 14, 2014 ]
    I have it hooked up wireless and it works good. [ DAVID A  Sep 15, 2014 ]
    The front of mine reads Wireless, Wifi Certified and Bluetooth. [ RON  Sep 15, 2014 ]
    It works both wired and wirelessly. Need to be wired however for fimware updates. [ CARL  Sep 14, 2014 ]
    Works wirelessly but you may need a repeater if your router is far away. [ Anthony  Sep 14, 2014 ]
    My zone 2 with this unit runs outdoor speakers. The unit is in a built-in in my living room. Using the bluetooth source outside with my phone being paired keeps me distance limited. How would I hook up a bluetooth range extender to this unit and which one would be compatible? thanks in advance [ Mike  Sep 28, 2014 ]
    I forwarded your question to an Advisor and they responded with the following: The Onkyo definitely wants to see an 8ohm load. The speakers from the old Yamaha system would make the amp in this receiver heat up and go into protect mode. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Aug 11, 2014 ]  Staff
