Bring the next-generation entertainment to your home
The TX-NR636 serves up revolutionary Dolby Atmos surround-sound complete with liquid 4K video at 60 frames per second. Dolby Atmos moves the sound around your theater more realistically to place you in the center of the action, creates a plane of sound over the listener’s head, and more accurately locates surround effects mixed for discrete channels. This receiver has HDMI supporting 4K/60 Hz and 21:9 display format 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). TX-NR636 paves the way for Ultra HD video playback at a liquid-smooth 60 frames per second. This is great news for PC gamers who can now add wall-shaking surround sound to their 4K/60 Hz experience.

Dolby Atmos multidimensional sound

The format adapts to any home theater layout incorporating height channels for a more enveloping soundfield with extremely accurate directional and overhead effects.

Hi-fi power and fidelity
WRAT (Wide Range Amplifier Technology) is all about current. Receivers need a lot of current to not only handle the sudden explosive actions scenes but also to reproduce the detail of quiet passages. We use a massive high-power transformer to drive discrete amps that help eliminate distortion and preserve the energy of music and movies. Delivering 165 watts per channel, the TX-NR636 packs a colossal punch for movies but still retains the pure musicality you need for two-channel playback. Also, Phase-Matching Bass Enhancement optimizes low frequencies while preserving mid- range clarity. It counters phase shifting by synchronizing the timing of different frequencies. The result is deep, well-defined bass that won’t blur vocals or strings.

Exclusive AccuEQ room calibration
Calibrating the sound to suit your room’s acoustics is simple with AccuEQ. 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.
