  • The TX-NR636 is one of the only A/V receivers to feature the latest HDMI 2.0 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.

    Onkyo's acclaimed WRAT (Wide Range Amplifier Technology), which provides the backbone that delivers Onkyo's classic sound, is coupled with Three-stage inverted Darlington Circutiry to the LCR channel to provide a big soundstage, superb timing, brilliant definition, and enough low-end grunt to make your speakers sing. The TX-NR636 packs a colossal punch for movies but still retains the pure musicality you need for two-channel playback.

    Built-in Wi-Fi® for universal hi-res streaming from PC, NAS, and smartphone is just the beginning. 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 built in Bluetooth. An HDMI/MHL terminal connects smartphones to display 1080p video with 7.1 channels of surround sound. Throw in a dedicated phono input, 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.

    Feel Every Dimension in Dolby Atmos

    Enter a new world of sound with Dolby Atmos®. It transports you from an ordinary moment into an extraordinary experience with captivating, multidimensional sound that fills your room with amazing richness and depth. Music, people, and objects come alive in breathtaking detail and flow in precise choreography all around you, making you feel like you are truly there.

    This Onkyo receiver features Dual 32-bit DSP engines to decode and scale Dolby Atmos to your home theater layout. With 7 channels of high-current amplification, you can unlock the full experience with in-ceiling height channels or Dolby Atmos-enabled speakers to augment a standard surround sound home theater setup for stunningly detailed sound that comes alive from all directions, including overhead. Additionally, a new Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system.

    Welcome to a new world of sound that delivers the full impact of entertainment. It will move your mind, body, and soul.

    Hi-Fi Power and Fidelity   Exclusive AccuEQ Room Calibration
    WRAT (Wide Range Amplifier Technology) is all about current. Receivers need a lot of current not only to 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. 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.   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.
