Product Description

Onkyo TX-RZ830 9.2-Channel Network AV Receiver brings a high-end approach to build and sound to the middle of the brand's AV receiver range. Onkyo's top-of-the-line high-current digital architecture is deployed with spectacular results: fluency, frequency range, transient response, and detail resolution are unbeatable at the price.

With sheer high-current power needed for edge-of-the-seat movie thrills and joyful stereo listening, the TX-RZ830 presents as a high-fidelity reference component loaded with connections needed for a custom install lasting well into the future.

At a Glance

Onkyo’s premier mid-class AV receiver unlocks complete 7.2.4-ch object-based audio coverage (outboard stereo amp required), universal 4K HDR pass-through and custom Dynamic Audio Amplification housed in a robust aluminum-fronted chassis, ideal for high-resolution music including Direct DSD 11.2 MHz, LPs via phono pre-amp, SACD from Blu-ray player or music streamed over AirPlay.

THX Certified Select

THX Certified Select guarantees cinema-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 3 meters and volume 57 cubic meters.

Dynamic Audio Amplification

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.

Dolby Atmos and DTS:X

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 for even more expansive 7.2.4-ch playback. Enjoy seamless top-to-bottom, side-to-side, and front-back coverage with in-ceiling speakers and floor-standing speakers. Individual sounds aren’t tied to channels and move around your audience.

3D Sound Solutions

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

Chromecast Built-in

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. If you have a device with the Google Assistant built-in, you can control music on the TX-RZ830 by voice.

Ready for DTS Play-Fi

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 synchronise music in every room.

FlareConnect Multi-room

FlareConnect shares audio from network and external audio input sources between compatible components. Enjoy effortless multi-room playback of LP records, CDs, network music services and more with supported components and speaker systems. Music selection, speaker grouping, and playback management across the home are built into the Onkyo Controller app.

Powered in 3 Zones

With a 5.2-ch cinema 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 (audio via HDMI inputs and S/PDIF audio not supported in Zone 3), to be synced across rooms simultaneously, or a unique source to be played in every zone at once. Zone 2 and Zone 3 pre-/line outputs are ideal for sharing sources to existing hi-fi systems.

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 equalisation.

Wi-Fi and Bluetooth

Built-in 5 GHz/2.4 GHz Wi-Fi provides network stability for streaming, Onkyo Controller app, and multi-room audio. Bluetooth wireless technology is also on board for easy mobile or laptop connection.

Streaming Services

Find and stream music from iPad, iPhone, Mac, and PC over the Apple AirPlay wireless audio platform. Further, Amazon Music, Spotify, TIDAL, Deezer and TuneIn are all set into the system GUI making selection easy using Onkyo Controller or Onkyo Music Control App.

4K 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 HDMI inputs, 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.
