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.

Onkyo's free remote app for Apple and Android

Listen to music from smartphones and networked computers using Onkyo's free remote app for Apple and Android.

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.

    I've had this connected for only 24 hours, but so far I'm very impressed. -Very easy to setup. Calibration is quick. The on-screen display walks you through everything. -Sound is very sharp and clear. -Though somewhat basic, the Onkyo app is quick and easy to use.

    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.

    Pros: Crutchfield is # one in my book for price and product Thanks

    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.

    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.

Have to get used to the remote and working all of the features .It was super easy attaching everything.My router is in a upstairs bedroom I have to get it down in the living room because my internet connection was only at 59%.I did not use the microphone attachment to fine tune anything. I may do that in the future if I feel there is a need .

    First new receiver in 15 years. Amazed at features and sound quality. Input output options perfect well organized. Only thing would have liked would be a master output AC plug to get full control of powder to all inputs from receiver via a panamax line conditioner type device

    Pros: everything

    Cons: none so far

    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, Central Ohio on Monday, 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.

    Excellent receiver

    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

    Great Value

    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.

    Talked with rep from Crutchfield. He suggested this product to replace my 10yr old Yamaha receiver. The reason I checked into Onkyo is my installer and repair person recommended it because it was so easy to install and set up. So far I am very satisfied with it. I'm not a hi tech guy and it appears to have way more features than I will use but sound is great and picture on tv is more than adequate. I think it will be good choice. Have had it 2 weeks now

    I'm a great Onkyo fan. Have had their receivers for many years. I bought this one for a new living area and have it attached to my Samsung 65" 4K TV. Awesome sound. Have never had any issues in the last 12 years with any of my Onkyo products.

    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, Washington on Saturday, 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.

Onkyo tells me its going into protection mode. Really? On a brand new unit with little use and connected to a high end power conditioner? Sadly I am findind others with this exact problem.

    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, Marlton, New Jersey on Tuesday, 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, Detroit, Michigan on Monday, 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.

    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: 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.

    Almost good enough

    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

    User-Friendly Receiver

    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.

    Cons: non so far

    Great for Android users

    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 d
