Product Information

Immense power for unparalleled speaker control

 

A glance at the TX-RZ840’s imposing front panel reveals a component built for one purpose: making your smile wider as the volume goes higher. Its thick chassis is loaded with custom parts tested and tuned to THX® Certified Select™ reference standards, handling massive current flows for the sound you feel emotionally and physically. Beyond 3D surround supporting IMAX® Enhanced*1 content up to 11.2 channels, and a finessed touch that breathes life into stereo music, the receiver forms a hub for house-wide entertainment with Next-Generation Network Audio integrating AirPlay 2, Works with Sonos, Chromecast built-in*2, and moreover 802.11ac Wi-Fi®*3. Three-zone powered D/A audio distribution is easily managed from your smartphone. With state-of-the-art connectivity and custom-installation interfaces included, it’s the TX-RZ840’s visceral presence you’ll find most difficult to resist.  

 

*1 Enabled with a future firmware update. *2 The unit may automatically download and apply an Over-the-Air software update during setup. *3 Some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.

 

 

Experience IMAX® Enhanced 

This Onkyo A/V receiver is released under the IMAX Enhanced* program, which features DTS:X immersive audio decoding that is optimized to properly reproduce the full dynamic range of IMAX theatrical sound mixes available in digitally re-mastered IMAX Enhanced content. The IMAX Mode reproduces lMAX Enhanced content at the highest levels, just as the filmmakers intended. IMAX Enhanced versions of films, from Hollywood blockbuster movies to documentary films, are scheduled for 4K HDR streaming and Ultra HD Blu-ray™ release.

* Enabled with a future firmware update.

 

THX® Certified Select™ cinema-reference sound 

THX Certified Select guarantees the same reference volume level of a commercial cinema in rooms where the viewing position is about 3.5 m 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® and DTS:X® 

Dolby Atmos and DTS:X formats map sound in 3D space, allowing them to move around the room and immersing your audience in the film. With 11.2-ch pre-outs and 11-ch processing, you can enjoy 3D sound through a 7.2.4 layout (external power amp required), or use built-in amps for a 5.2.4 or 7.2.2 layout. Enjoy classic titles through your height-enabled speaker system with Dolby Surround® and DTS® Neural:X finding cues in legacy soundtracks and upmixing for spatial playback.

 

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 speakers.

* Enabled with a future firmware update.

 

Dynamic Audio Amplification – RZ Series Build 

DAA stabilizes power delivery for accurate control and spectacular dynamics. High-Current Low-Noise Power Transformer and custom 15,000 μF high-current smoothing capacitors deliver instant power while non-phase-shift amps capture a 5 Hz–100 kHz frequency response. To keep them cool, an extruded aluminium heat-sink with black anodized paint controls resonance frequencies while more effectively cutting thermal distortion. Behind the aluminium front panel are hand-selected audio parts. DAA produces a visceral musicality that makes every note an emotionally moving experience. 

 

New upgrades reduce noise and boost power 

Additional refinements control noise, boost power, and improve S/N performance. A new HDMI® board has shorter signal-paths and large, well-finished grounds for A/V signal integrity. SoC is isolated to reduce interference noise. The power-supply line is reinforced in pursuit of smooth power delivery. These contribute to punchier bass and improved localization on an expanded sound-stage. 

 

Next-Generation Network Audio 

Access streaming content from Amazon Music, Spotify®, TIDAL, Deezer, and TuneIn and share sound as part of a multi-room system via Works with Sonos, Chromecast built-in*, AirPlay 2, DTS Play-Fi®, and FlareConnect™.  

* The unit may automatically download and apply an Over-the-Air software update during setup.

 

Works with Sonos 

The TX-RZ840 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*.  

* Sonos Connect sold separately. Sonos app is available free for iPad, iPhone, and Android™ at the App Store and Google Play. Please confirm device and OS compatibility before installation.

 

Chromecast built-in with the Google Assistant

Stream any music from your smartphone, laptop, or PC to the receiver with ease. Control playback with Chromecast-enabled apps you know and love from your iPhone, iPad, Android phone or tablet, Mac or Windows® laptop, or Chromebook. If you have a smart speaker featuring the Google Assistant, you can cue, play, and control music playback by voice.  

Note: The unit may automatically download and apply an Over-the-Air software update during setup.

 

Whole home audio: just add speakers

Orchestrate audio playback in up to three rooms at once using the Onkyo Controller app. The TX-RZ840 has two extra DACs to distribute unique or synced D/A audio sources via Zone 2 and Zone 3 speaker outputs, including HDMI®/SPDIF/NET/Bluetooth®. With nine amps, you can enjoy a 5.2.2-ch layout in Main with powered Zone 2 audio, or a 5.2-ch surround system in Main with powered audio distribution to Zone 2 and Zone 3.

 

Quad-core SoC supports 802.11ac Wi-Fi®

A powerful SoC (System on a Chip) processes multiple tasks at once. It evolves network functions and supports the latest high-speed 802.11ac (2x2 MIMO) specification while compatible with 802.11 b/g/n dual-band routers.

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

 

Clarify voice dialogue in-program instantly

Vocal Enhancer solves inaudible dialogue in TV programs and movies. DSP technology identifies voice frequencies so you can conveniently adjust them using remote-control keys or controls on the front panel.

 

Versatile Zone 2/Zone B line-out

Connect your supported hi-fi system via analogue RCA input to the AVR’s Zone 2/Zone B line-out. In Zone 2 mode, you can play the same or different analogue/digital sources (including SPDIF and HDMI) in either or both rooms at the same time. Zone B mode is an ideal match for a supported wireless transmitter. Listen to any source through wireless headphones for disruption-free late-night TV entertainment.

 

AccuEQ Advance with AccuReflex™

AccuEQ Advance room acoustic calibration uses nine-point 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 the native quality.
