HDMI 2.1 with 8K

HDMI® 2.1 is the latest update to the HDMI® specification, supporting eARC along with higher video resolutions and refresh rates such as 8K60 and 4K120, plus Dynamic HDR formats. With 8K providing twice the horizontal and vertical resolution of 4K and four times the pixel count, combined with a 60Hz refresh rate, you get sharp, smooth playback of fast-moving content. HDMI 2.1 with 8K and eARC ensures your system delivers the cleanest, most precise picture quality both today and well into the future.

Ultimate 4K Gaming Experience

4K/120 delivers ultra-fast motion with UHD images that remain crisp and razor-sharp, making it especially beneficial for sports, action films, and high-performance gaming where smooth clarity is essential.

Additional Features

Built-In Streaming Services
Spotify®, TIDAL, Deezer, TuneIn, and Pandora® are integrated into the system. Use dedicated apps (where available) or the free Onkyo Control App for Apple and Android devices to browse and play music.

Works with Sonos Certified
This receiver can connect to your existing Sonos Home Sound System, or serve as the starting point for a new one, by pairing it with a Sonos Port.* As a Works With Sonos Certified AVR, it provides seamless integration with the Sonos ecosystem, automatically waking, switching inputs, and playing at the set volume using the Sonos Volume-Pass Through feature from the Sonos app.

AccuEQ Calibration Ready
AccuEQ simplifies the initial setup of your home theater system by properly calibrating your receiver and speakers for optimal performance in your listening environment. It measures speaker distance from the listening position, adjusts sound pressure levels, and sets crossovers to route low-frequency content to the subwoofer. The result is balanced, clear, and full-spectrum surround sound.

Dolby Atmos® and DTS:X® – Setting Sound Free
Dolby Atmos® and DTS:X® formats let engineers position sound anywhere in 3D space, moving effects between speakers around the room to immerse your audience in movies and games. These formats also enhance classic titles, with Dolby Surround® and DTS® Neural:X extracting overhead cues in legacy soundtracks for heightened spatial realism.

Dolby Atmos® Height Virtualizer
When playing any Dolby® format, activating Dolby Atmos Height Virtualizer creates a more immersive experience by simulating virtual surround and overhead sound effects from traditional speaker layouts, without the need for extra speakers.

Ready for DTS Play-Fi®
DTS Play-Fi lets you stream high-quality music from online services, networked media servers, or your device library over Wi-Fi® to multiple compatible products using the Onkyo Music Control App for iPad, iPhone, and Android devices. DTS Play-Fi synchronizes music across every room, or allows each family member to play their own selection in a room or group of rooms, creating a versatile multi-room audio system.

Dynamic Audio Amplification
Refined over 70 years, DAA combines a custom High-Current Low-Noise Power Transformer, specially selected capacitors, and discrete amp output stages. Its unique topology prevents phase shift, while high current improves speaker control for true dynamic speed. Designed to drive 4-ohm loads across all channels, DAA delivers both finesse and power.
