Benefits of Onkyo TX-RZ840 9.2-Channel Network A/V Receiver:
Experience IMAX® Enhanced
This Onkyo A/V receiver is released under the IMAX Enhanced* program, which is feature-packed with DTS:X immersive audio decoding that is optimized to effectively 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 top-notch levels, just as the filmmakers set out to. IMAX Enhanced versions of films, from Hollywood blockbuster movies to documentary films, are scheduled for 4K HDR streaming and Ultra HD Blu-ray™ release.
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 sounds in 3D space, allowing them to move around the room and rendering an immersive experience for 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 spectacularly immersive aural 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 aluminum heat-sink with black anodized paint controls resonance frequencies while radically cutting thermal distortion. Behind the aluminum front panel are hand-selected audio parts. DAA produces a visceral musicality that makes every note a riveting experience
Ready for DTS Play-Fi®* Multi-room 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.
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 side-lined 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 also 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.
