After a simple set up, your Onkyo A/V receiver will seamlessly tie into Sonos, instantly waking, changing inputs and playing at the volume you command through the familiar Sonos app.

THXCertified Select theater-reference audio
THX Certified Select guarantees theater- reference sound in your home. To gain certification, amplifiers must pass severe bench-tests covering every aspect of performance. THX Certified Select components suit rooms where screen-to-seat distance is about 10 ft. (3 m) and volume 2,000 cubic feet (57 m3).

Dolby Atmosand DTS:X at up to 7.2.4 channels
Hear Dolby Atmos and DTS:X soundtracks through 7.2.2 or 5.2.4 channels. Connect an outboard power amp via 11.2-multichannel pre- outs and enjoy seamless top-to-bottom, side-to- side, and front-back coverage with four in- ceiling speakers and seven floor-standers. Individual sounds aren't tied to channels and move naturally around your audience.

Dolbyand DTSsolutions for 3D upmixing
DTS Neural:X technology and Dolby Surround find cues in legacy soundtracks and upmix for playback through systems with height channels. Cross- compatible with Dolbyand DTSformats, enjoy spatially realistic and natural sound from your existing DVD and Blu- ray Disc library or streaming service.

Chromecast built-in works with the Google Assistant
Stream any music from your smartphone, laptop, or PC to the receiver with ease. Control playback with Chromecast-enabled apps from your iPhone, iPad, Android phone or tablet, Mac or Windows laptop, or Chromebook.

Ready for DTS Play-Fimulti-room audio technology
DTS Play-Fi technology allows you to enjoy quality music from online services, media server, and mobile device to any number of compatible products using Onkyo Music Control App. DTS Play-Fi technology can synchronize music in every room.

AccuEQ Advance for Accurate Calibration
AccuEQ sets speaker distance, SP level, and crossover. In addition, AccuEQ Advance employs multi-point measurement to remove standing waves from your listening space, which compromise audio quality and bass response. The technology also detects and compensates for background noise, such as the hum from an HVAC, to ensure accurate equalization.

AccuReflex
AccuReflex technology aligns the phase of up- firing "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object- based soundtracks.

Powered sound in three zones
With a 5.2-ch theater layout in Zone 1 (Main), the remaining four channels can drive speakers in Zone 2 and Zone 3. As well as analog distribution, dedicated DACs enable digital sources* to be synced across rooms simultaneously, or a unique source to be played in every zone at once. Zone 2 and Zone 3 line-level outputs are ideal for sharing sources to existing hi- fi systems.

Manage Music with Onkyo Controller app
Onkyo Controller app collects streaming services and network-attached audio into one interface. Select sources, control playback, and distribute audio.

Dynamic Audio Amplification (DAA)
The DAA philosophy places less emphasis on lab measurements and more on how the sound actually feels in real life. High-current drive and expert tuning deliver natural transient response, the key to involving sound. A deep power reserve arrives instantly when action explodes on screen, adding adrenaline to the film experience. Accuracy and control is maintained with custom transformer and custom block capacitors, aluminum heat sink, non-phase-shift amp circuitry, and discrete output transistors. With VLSC noise filtering (Front L/R) for improved fidelity, DAA is built for compelling sound. Onkyo's dynamic audio amplification delivers massive power at 225 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)/ 100 W/Ch (8 Ohms, 20 Hz-20 kHz, 0.08% THD, 2 Channels Driven).

Supports 4K HDR, BT.2020, 4K/60 Hz, and HDCP 2.2
Welcome film-like 4K video bursting with bright and vibrant colors enabled by High Dynamic Range (HDR) to your supported TV display or projector. The receiver's HDMIinputs, Main Out, and Sub/Zone 2 Out pass HDR10, HLG, and Dolby Vision formats through to compatible displays. These terminals support the BT.2020 4K video standard, 4K/60 Hz playback, and HDCP 2.2.
