Onkyo TX-RZ730 / TX-RZ830 9.2 wireless multi-room A/V receivers

Onkyo promises your home cinema set-up will be able to challenge your local commercial cinema thanks to their new Onkyo TX-RZ730 and TX-RZ830 9.2-channel A/V receivers with 175 W/Ch and 180 W/Ch respectively (measured at 6ohms, 1kHz, 1% THD, 1-ch driven).

These THX-Certified Select A/V receivers deliver cinema-reference sound in rooms of up to 57m3 (2,000 ft3). We are told that this has been proven by 2,000 bench-tests in 75 categories, covering 14,000 data points at THX Labs.

Onkyo TX-RZ730 and TX-RZ830

Both of the new Onkyo receivers are equipped with 11.2-multichannel pre-outs and processing. This means you can enjoye Dolby Atmos and DTS:X soundtrack reproduction through speaker layouts of up to 7.2.4-ch (with an outboard stereo amp).

Furthermore, you can optionally power digital and analogue audio through speakers in Zone 2 and Zone 3 with a 5.2-ch speaker layout in the media room. Alternatively, you can enjoy object-based audio through a 5.2.2-channel layout with powered audio distribution in Zone 2. Both receivers include Zone 2 and Zone 3 pre-/line-outs to share audio to hi-fi systems in other rooms.

Thanks to the Dynamic Audio Amplification’s custom-fabricated, high-output transformer and large customised block capacitors, they also boast class-beating current flow. This is the secret to instantaneous dynamic response and precise control.

Additionally, the patented VLSC (Vector Linear Shaping Circuitry) on Front L/R channels eliminates digital noise for source-faithful audio playback.

With wide 5Hz-100kHz frequency response and deep reserves of high-current power, both receivers produce the earth-shaking bass and crystal clarity that’s essential for thrilling audio entertainment.

AccuEQ

The TX-RZ730 and TX-RZ830 feature AccuEQ Advance room acoustic calibration technology.

As well as setting parameters such as speaker distance, SP level, and crossover, AccuEQ Advance uses multi-point measurement to eliminate standing waves from the listening space.

The technology also detects and compensates for subtle background noise. AccuReflex technology aligns the phase of directional and non-directional sounds for comfortable playback through Dolby Atmos-enabled speaker systems.

Dolby and DTS

Both receivers feature Dolby Surround and DTS Neural:X upmixing solutions. These cross-compatible technologies re-map legacy soundtracks commonly encoded on DVD, Blu-ray Disc, and streaming video. This leads to you to being presented with a highly realistic listening environment.

Multi-room audio

Both receivers enjoys Chromecast built-in. This enables you to stream any music from Chromecast-enabled apps for iPhone, iPad, Android phone or tablet, Mac and Windows PC, or Chromebook. Playback can be controlled by voice with a smart speaker featuring the Google Assistant, such as Google Home.

DTS Play-Fi technology enables high-quality music playback from online services, media servers, and mobile devices to any number of compatible products using Onkyo Music Control App. DTS Play-Fi technology can synchronise music in every room and is easily used by any family member.

Proprietary FlareConnect technology shares audio from network sources and external audio inputs between compatible components. Enjoy effortless multi-room playback of LP records, CDs, network music services, and more with supported components and speaker systems.

Amazon Music can be accessed via the Onkyo Music Control App. You can get TIDAL, TuneIn, Deezer, and Spotify through Onkyo Controller.

Onkyo Controller presents local and network audio for streaming together with remote-control functionality.

The receivers also include Bluetooth wireless technology for streaming virtually any audio from apps running on PC and mobile. Finally, AirPlay network audio streaming technology is built in.

Analogue and digital audio

Analogue enthusiasts are treated to a discrete, low-noise phono pre-amplifier for turntable connection.

The TX-RZ830 adds Pure Audio mode to minimise unwanted interference, with both supporting Hi-Res Audio via network and USB storage devices.

The TX-RZ730 plays DSD5.6 MHz/2.8 MHz while the TX-RZ830 supports direct playback of DSD11.2 MHz files. Both support 24-bit audio up to 192kHz in FLAC, WAV (RIFF), AIFF, and ALAC formats.

On the video side, the TX-RZ730 and TX-RZ830 are ready for the latest premium content with HDMI pass-through of HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision formats. Additionally, 4K/60p, BT.2020, 4:4:4, 24-bit, and HDCP 2.2-protected video are also catered for.

Six rear HDMI inputs, Main Out, Zone 2 Out (Sub Out on the TX-RZ730), and a front HDMI input are included on both models.

As well as ample digital and analogue audio inputs, plus assignable component and composite video inputs for legacy devices, the receivers have a 12v trigger output and IR input.
