Welcome to 8K Ultra HD with the latest HDMI®

Features defined in HDMI 2.1 enable 8K/60p passthrough to a compatible display. As well as HDR10 and HLG, HDR10+ and Dolby Vision™ formats optimize brightness, contrast, and color frame-by-frame. All HDMI terminals support HDCP 2.3, while eARC on Main Out passes multichannel audio (including Dolby Atmos® or DTS:X) from TV to AVR for decoding and amplification. QMS (Quick Media Switching) reduces screen blanking when switching HDMI sources.

Note: features defined in HDMI 2.1 supported on HDMI inputs 1–6, Main Out, and Sub/Zone 2 Out in Sub Mode output.

Experience lag-free gameplay

Transform virtual worlds with 3D sound and get a competitive edge with all-new HDMI features for gamers. VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and QFT (Quick Frame Transport) eliminate lag, stutter, and frame-tearing for more fluid and responsive gameplay.

Note: features supported on HDMI inputs 1–6, Main Out, and Sub/Zone 2 Out in Sub Mode output.

Dolby Atmos and DTS:X

Dolby Atmos and DTS:X formats map sound origins as they are perceived in real life and transpose them around your audience for a captivating entertainment experience. Enjoy 3D sound through a 5.2.4 or 7.2.2 layout or connect a stereo amp and expand to 7.2.4 channels. Rediscover classic titles through your height-enabled system with Dolby Surround® and DTS® Neural:X. These technologies analyze legacy soundtracks for spatial cues and upmix for immersive 3D playback.

Dolby Atmos Height Virtualizer

Dolby Atmos Height Virtualizer enhances Dolby® formats for a more immersive experience. It creates virtual surround and height effects using a traditional speaker layout.

Exclusive refinements for clear soundy

HDMI board has short signal-paths and well-finished grounds that suppress noise. SoC board is isolated from audio circuitry, reducing interference. Reinforced power-supply line and refined power-amp grounds with copper bus bar reduce circuit noise for thick, clear, and detailed sound.

SMART AV Receiver™ multi-room entertainment

SMART AV Receiver is the heart of your home entertainment system. Access streaming content from Amazon Music HD*, Spotify®, TIDAL, Deezer, and TuneIn and share sound as part of a multi-room system via Works with Sonos, Chromecast built-in, AirPlay 2, and DTS Play-Fi®.

Works with Sonos

Add this receiver to your Sonos Home Sound System just by pairing it with a Sonos Connect or Port*. The AVR ties into the Sonos ecosystem, changing inputs and responding to volume commands from the Sonos app*.

*Sonos Connect and Port sold separately. Connection of 1–3 Sonos devices is supported. Sonos app is available free for compatible iPad, iPhone, and Android™ devices at the App Store and the Google Play Store.

Chromecast built-in™ works with Ok Google

Stream music from your smartphone, laptop, or PC to the receiver via Chromecast built-in and control playback from Chromecast-enabled apps from iPhone, iPad, Android™ phone or tablet, Mac or Windows® PC, or Chromebook™. Cue, play, and control audio on this and other supported devices just by using your voice.

Works with Alexa

Use your voice to control the AVR by issuing commands through an Alexa device. Whether you want to listen to music, radio stations, or podcasts, all you have to do is ask. It also supports multi-room music* played on multiple devices.

*Multi-room music may require a firmware update.

Connect speakers for powered multi-room sound

Powered Zone 2 and Zone 3 outputs connect passive speakers in two other rooms with a 5.2-ch speaker system in your main listening space. Together with MAIN, Zone 2 and Zone 3 DACs support D/A audio playback (including HDMI, SPDIF, and NET) in three rooms. You can sync the same track or play different songs in each room using Onkyo Controller to manage your entertainment.

Note: Zone 3 supports analog/NET only. Zone 2 HDMI audio available via inputs 1–3. HDMI and SPDIF support PCM only.

5 GHz/2.4 GHz Wi-Fi® supports 802.11ac standard

Isolated 1.8 GHz quad-core SoC performs multiple processing tasks at once. It evolves network functions and supports the 802.11ac (2x2 MIMO) standard for stable multi-room audio streaming.

Note: some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.

Bidirectional Bluetooth® wireless technology

Send or receive audio via Bluetooth wireless technology. Stream from your laptop, digital audio player, or mobile to the receiver over SBC or AAC, or share what’s playing in the main zone* to a pair of wireless headphones using SBC, aptX™, or aptX HD codecs.

*Audio via Chromecast built-in and Works with Alexa excluded.

Convenient Zone 2 and Zone B pre-/line-out

RCA pre-/line-out has two modes: Zone 2 supports connection of active speakers or a hi-fi system, and can sync D/A audio in MAIN and Zone 2 or play a different source in each. Zone B plays MAIN audio through compatible wireless headphones via a connected headphone dock.

Note: Zone 2 mode supports HDMI audio via inputs 1–3. SPDIF and HDMI support PCM only. Zone B mode is line-level only and supports encoded or PCM signals (all inputs) in MAIN and Zone B.

Dirac Live® Room Correction

Dirac Live analyzes your audio system and listening environment by examining acoustic data measured with a setup mic. It corrects both the timing and amplitude aspects of sound coloration using a mixed-phase correction filter throughout the listening area, not just a particular zone. Correction is performed automatically using a proprietary app for smartphone or tablet*. Dirac Live improves staging, localization, clarity, voice intelligibility, and bass response.

*Mobile device and AVR must be connected to the same local network.

Flexibility for customized setups

Connect an external power amp or motorized projector screen via the AVR’s 12 V trigger output and power them up automatically with your AVR, with CEC performing the same task for media players over HDMI. An IR repeater input lets you conceal the AVR away from the screen, ideal for bespoke cinemas. Ethernet and RS-232 terminals integrate the AVR into your automation system, with the former supporting setup and web browser control via PC.
