Onkyo TX-SR494 7.2 Ch. 4K UHD AV Dolby Atmos Receiver with DTS: X.


Escape the everyday with spatial surround-sound. From easy Bluetooth wireless streaming to the heart-pounding thrills of Dolby Atmos and DTS:X soundtracks, the TX-SR494 deepens enjoyment of daily life with great sound and smart features. Seven channels of high-current power give you freedom to choose a speaker layout that suits. Dolby Atmos Height Virtualizer* or DTS Virtual:X place sound overhead or behind if you don’t want height or surround speakers and both Dolby Surround and DTS Neural:X are on board. Rear surrounds, bi-amped front speakers, or Powered Zone B audio are also an option. AccuEQ with subwoofer EQ and AccuReflexTM for 5.2.2-ch Dolby Atmos-enabled systems clarify sound in any space. As the heart of your home theater, the TX-SR494 has HDMI terminals supporting HDR and 4K/60p video, while the GUI with OSD over HDMI, Zone B pre-/line-out, and Vocal Enhancer function make this receiver a joy to use as well as hear.

    Dolby Atmos and DTS:X formats allow engineers to map sound anywhere in 3D space, effects moving from speaker to speaker all around the room and wrapping your audience in the latest films and games. You can also enjoy your 3D speaker layout with classic titles. Dolby Surround and DTS Neural:X find overhead cues in legacy soundtracks and upmix for awesome spatial realism.

    Dolby Atmos Height Virtualizer

    When playing any Dolby format, engaging Dolby Atmos Height Virtualizer* enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.

    Ready for 4K HDR entertainment

    Enjoy support for HDR (High Dynamic Range) video including HDR10, HLG, Dolby Vision, and BT.2020. The 4:4:4 color space is also supported. Six HDMI inputs, ARC-ready MAIN OUT, and SUB OUT pass 4K/60p and HDR video from player to compatible TV and projector and all terminals are HDCP 2.2 compliant.

    Smooth and easy Bluetooth streaming

    Whatever audio is playing on your phone, tablet, or PC app can be streamed to the receiver with Bluetooth wireless technology. Once the receiver has paired with and remembered your device, it will start playback automatically whenever it detects an incoming Bluetooth audio stream.
