Choose a speaker layout to suit your room, from a space-saving 2.1-ch setup enhanced with 3D surround-sound courtesy Dolby Atmos Height Virtualizer* or DTS Virtual: X® to a 3.2.2-ch system for native object-audio playback. Whatever way you play it, dynamic power is ready to thrill thanks to authentic high-current analog amps backed by a thumping custom transformer. For true-to-life video, the AVR supports 4K/60p and HDR video passthrough. If all this tech sounds scary, relax: every aspect of this product is designed to erase frustration, from the automated AccuEQ system calibration to a quick connection guide. The receiver integrates your players and TV and adds practical features such as a Vocal Enhancer for clear dialog. There’s even a Zone B line-out to distribute all your home theater sources to a component with an analog RCA line-in, such as a wireless headphone dock or hi-fi system. Or just sit back and stream from apps via Bluetooth® technology and let Advanced Music Optimizer™ enrich every note of the golden Onkyo sound.

Dolby Atmos® and DTS:X® – setting sound free

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.


Outfitted with the latest Bluetooth technology, this receiver gives you the freedom to choose how loud you experience your music, movies, and games. Listen quietly through your Bluetooth headphones without sacrificing sound quality or waking your kids. Or, while the rest of the family enjoys the speakers at a moderate volume, accommodate one person who may need help hearing via Bluetooth headphones.
