Seven channels of high-current power give you the freedom to choose a speaker layout that suits you.

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.
