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 or 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.

    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.

    Delivered to Hawaii in 2 business days Awesome. Easy to install and so far trouble free performance.

    Pros: Easy to hook up, a lot of HDMI options, visually improved the picture on my Samsung 53" Flat screen and does a great job of balancing the sound for the room.

    Cons: none

    Great receiver!

    Written By JimC, Bargersville, IN on Monday, December 15, 2014

    Crutchfield Customer Review (What's this?)

    This receiver came recommended to me by a guy I work with. Others also recommeded Onkyo to me. We have a Harmon Karden and have had all kinds of issues with it. 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 :(

    Pros: Great sound and features!

    Cons: Smart Hub on tv needs to be run via Optical to work.

    Crutchfield Customer Review (What's this?)

    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.

    UHD TV Must!

    Written By Russ M, Orlando, FL on Monday, December 08, 2014

    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

    Written By Bill, West palm beach, florida on Thursday, October 30, 2014

    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!

    Replaced my Yamaha

    Crutchfield Customer Review (What's this?)

    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!

    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.

    Almost good enough

    Written By Pete D, Norfolk,VA on Saturday, 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

    I am a neophyte in setting up a stereo system, but had no problems at all with installation of this receiver. Everything was explained well in the documentation, and the receiver itself is very easy to use. The sound is terrific.

    Cons: Can't rename keys to indicate equipment actually hooked up

    Onkyo TX-NR636

    Written By BillW, Utica, Ky on Friday, August 01, 2014

    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.

    Great for Android users

    Written By Scott, Raleigh, NC on Sunday, July 06, 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.

    Questions & Answers Ask the community. Share your knowledge.

    7 questions already asked

    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

    I forwarded your question to an Advisor and they responded with the following: This receiver will not support a 4 ohm speaker for center channel. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  May 28, 2014 ]  Staff
