Works with Sonos
This Onkyo receiver can join your existing Sonos Home Sound System, or be the start of a new one, just by pairing it with a Sonos Connect. The AVR ties into the Sonos ecosystem, waking, changing inputs, and playing at the desired volume on command from the Sonos app.

THX Certified Select Theater-reference Sound
THX Certified Select guarantees the same reference volume level of a commercial theater in rooms where the viewing position is about 10–12 ft. from the screen. To gain certification for reference sound within strict THX sound quality parameters, receivers must pass 2,000 bench-tests in 75 categories covering 14,000 data points.

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.

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.

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.

Dynamic Audio Amplification
Refined over 70 years to deliver emotion in high fidelity, DAA features a custom High-Current Low-Noise Power Transformer, customized capacitors, and discrete amp output stages. Unique topology prevents phase-shift while high current improves speaker control for true dynamic speed. Driving 4-ohm loads through all channels, DAA has power to move.

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.

Apple AirPlay 2
Apple AirPlay 2 lets you effortlessly stream music or podcasts to multiple audio devices throughout your home using any Apple device or by asking Siri - and it all stays in perfect sync. Create multi-room groups or stream to just one device. (Apple Airplay 2 available via future firmware update. )

Easy Bluetooth Volume Control
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.

AccuEQ Room Acoustic Calibration with AccuReflex
AccuEQ Advance room acoustic calibration uses ninepoint mic measurement to calibrate and EQ speakers and subwoofers and remove standing waves that arise when sound from the speakers resonates with sound reflecting off the walls, compromising its proper expression. During the process, background noise is ignored to ensure accurate equalization. AccuReflex optimizes 3D sound through height speakers by resolving phase-shift, resulting in a cohesive sound-field.

Connections for Custom Installation
The TX-RZ840 features a 12 V trigger output for an external component and an IR input for remote-control range extension. It supports IP control, RS-232C, and OSD output for custom installers. An optional rack-mount kit (IRK-180-4C) is available.

Supports eARC Audio Transmission
HDMI Main Out features eARC supporting HD audio transmission from an eARC-compatible TV to the A/V receiver via HDMI cable. It works with 3D audio formats such as Dolby Atmos and DTS:X as well as Dolby TrueHD and DTS-HD Master Audio lossless codecs. High bit-rate and object-based audio featured in videos streamed via Smart TV or smartphone app and a connected network media dongle can now be decoded and amplified by the A/V receiver at native quality.
