HDMI® 2.1 with 8K
HDMI® 2.1 is the most recent update of the HDMI® spec and supports eARC, a range of higher video resolutions and refresh rates including 8K60 and 4K120, and Dynamic HDR formats. 8K delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels; and combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action. HDMI 2.1 with 8K and eARC ensures your system is ready for the clearest and cleanest picture available both now and down the road.
Ultimate 4K Gaming Experience
4K/120 enables ultra-fast motion UHD images to be crisp and razor-sharp; and sports, action movies, and high-performance gaming benefit significantly.
Additional Features
BUILT-IN STREAMING SERVICES
Access to Spotify®, TIDAL, Deezer, TuneIn, and Pandora® are built into the system. Use dedicated apps (where available) or the free Onkyo Control App for Apple and Android devices to find and play music.

WORKS WITH SONOS CERTIFIED
This receiver can join your existing Sonos Home Sound System, or be the start of a new one, just by pairing it with a Sonos Port.* This Works With Sonos Certified AVR offers a best-in-class tie-in to the Sonos ecosystem, waking, changing inputs, and playing at the volume you want using the Sonos Volume-Pass Through feature from the Sonos app*.

ACCUEQ CALIBRATION READY
AccuEQ streamlines the initial setup of your home theater system and ensures your receiver and speakers are properly calibrated for the best performance in your listening space. AccuEQ calculates speaker distance from the listening position, adjusts speaker sound pressure level, and sets the speaker crossover. The latter selects the correct point to roll off low-frequency sound to the subwoofer. The result is clear and balanced full-spectrum surround 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 DTS PLAY-FI®
DTS Play-Fi allows you to enjoy high-quality music from connected online services, networked media servers, and your device library over Wi-Fi® to any number of compatible products using the Onkyo Music Control App for iPad, iPhone, and Android smartphones/tablets. DTS Play-Fi can synchronize the music in every room. Each member of your family can use their own device to listen to their music in a room or group of rooms. DTS Play-Fi lets you structure a comprehensive multi-room ecosystem that satisfies virtually any need.
