The new generation in high-definition entertainment is here in the shape of HDMI v2.0. The new guidelines have been set by the HDMI organisation with support for higher frame rates than are possible with the current 1.4 specification. Don't worry, it's unlikely you'll need to replace your entire HDMI cable system; High Speed cables in general will have enough bandwidth to support 4k and in some cases 8k video resolutions. The Onkyo TX-NR636 also supports the data rates necessary for super-HD video. A definitive future-proof home theatre amplifier.
The TX-NR636 wins prime position on your gear rack for three reasons. Firstly, it’s one of the only A/V receivers to support future Ultra HD movie streaming as well as 4K gaming at 60 fps with 4K/60 Hz-compatible HDMI inputs and HDCP 2.2 copy-protection compatibility. Qdeo upscaling technology also converts low-res DVDs and games into pin-sharp Full HD or 4K (if you have an Ultra HD display). Secondly, it sounds incredible, with Three-Stage Inverted Darlington Circuitry on the front and center channels for all-enveloping surround sound and musical two-channel audio. Thirdly, it’s extremely easy to use, with inbuilt Wi-Fi for universal hi-res streaming from PC, NAS, and smartphone. You can select from a wild variety of music streaming services and locate your network-attached libraries using the remote app, or stream almost any audio via Bluetooth. Overlaid menus with InstaPrevue technology make loading content fast and simple. Throw in an MM phono stage, room equalization, and powered Zone 2 and you’ve got a value-packed 7.2-channel powerhouse ready for the next wave of high-resolution entertainment.
Imagine playing the latest RPG blockbuster on your Ultra HDTV at a breathtaking 60 frames per second. Now add thunderous 7.2-channel surround sound from Onkyo. With HDMI terminals on your TX-NR636 receiver supporting 4K/60 Hz, this dream can be your reality. Even if you’re not planning on upgrading your current display right away, it’s good to know your receiver is ready for the future.
With Hollywood studios, satellite TV broadcasters, and video streaming services announcing a move to HDCP 2.2 copy protection for future 4K and Full HD releases, it’s important that your A/V receiver can handle this new standard. The TX-NR636 is one of the first A/V receivers to support HDCP 2.2, making it ready for next-generation Ultra HD streaming and broadcasting.
The TX-NR636 features Qdeo technology from Marvell to upscale low-res video to liquid-smooth 1080p (for HDTV) and 4K (3840 x 2160 pixels) with a compatible display. This means video from older gaming consoles and DVD players looks clean and sharp, giving old favorites a new lease on life.
The TX-NR636 has Wi-Fi and Bluetooth technology built in. Complete the setup, download our control app, and you’ve got a graphic remote control and range of streaming features in the palm of your hand. Or pair your Bluetooth-capable device and stream almost any audio to your home cinema. With Advanced Music Optimizer enhancement, music via Bluetooth has never sounded so good.
For lossless audio streaming, just tap on the Onkyo Remote App icon on your smartphone to find your music loaded and ready to stream with all the controls you’re used to. The receiver can switch on and select your preferred playback mode automatically.
Onkyo A/V receivers are engineered for universal hi-res compatibility and ease of use. Use the remote app to locate your 192/24 and 96/24 albums (including 5.6 MHz DSD playback) on PC or NAS and bask in the clarity, depth, and detail of high-resolution music.
If you can think of it, you’ll most likely be able to stream it. The receiver includes Spotify, AUPEO!, TuneIn, and now Deezer, the music subscription service available in over 200 countries and boasting a library of 25 million songs. You can search for available music using your free Onkyo remote app.
The front-panel USB port also plays almost any audio format from mass-storage-class drives. As well as compressed files, there’s support for FLAC, WAV, ALAC, Dolby TrueHD (48 kHz), and DSD. You can also connect a PC, smartphone, or music player using one of the many digital and analog inputs.
WRAT (Wide Range Amplifier Technology) is all about high current. You need it to stay in control when speaker impedance fluctuates, and to grip without clipping as the soundtrack explodes into action. We use a massive high-power transformer driving ultra-low-distortion Three-Stage Inverted Darlington Circuitry. Combined with high-resolution processing, the TX-NR636 packs a colossal punch for movies while retaining musicality for two-channel playback.
An HDMI/MHL terminal is included to connect smartphones and other electronic devices, allowing you to display 1080p video and other media on your HDTV with 7.1 channels of surround sound.
Dolby Pro Logic IIz adds height to the soundstage with two Front Height channels immersing you deeper into the film. The system upmixes stereo or 5.1 sources to 7.1 channels, and offers a number of optimized listening modes.
Powered Zone 2 speaker terminals (and a Zone 2 line-out) let you power audio in another room equipped with stereo speakers. You can also assign surround back channels to bi-amp your front loudspeakers.
The free Onkyo Remote App gets your system up and running in moments. All major playback controls, speaker adjustments, listening mode/input source selections are at your fingertips. Tap the music icon for internet radio or to hear the music stored on your smart mobile, PC, or NAS.
If you want to quickly adjust a speaker level, switch DSP modes, or change inputs, the “Q” remote control button does it in seconds by overlaying a simple transparent menu on screen. Use InstaPrevue technology to preview content playing on any HDMI-connected component—the overlaid video thumbnails are great for keeping an eye on a cable channel while you’re watching a Blu-ray, for example, and also make video switching very clear and simple.
AccuEQ optimizes surround-sound and two-channel audio to suit your listening space. In particular, AccuEQ extracts the best possible performance from your front speakers to make stereo listening more dynamic and exciting. The system analyzes speaker setup and room acoustics from one listening position (which simplifies the calibration process) and optimizes frequency response and output levels for maximum clarity.

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.
Onkyo’s RI system lets you operate multiple RI-compatible components through a single remote control.
192 kHz/24-bit DACs enable the best possible reproduction of standard and high-definition audio formats.
Select Onkyo A/V receivers offer integrated system control with certain HDMI-compatible high-definition displays, DVD and hard-disk recorders, and Blu-ray Disc players. With one remote control, you can control certain functions, including Standby, Volume and Direct Change.
