Works with Sonos

With Sonos Connect, the awesome home theater you’ve built around your Onkyo receiver can now be part of your existing Sonos Home Sound System, or the start of a new one. Instantly upgrade the music streaming capability of your home theater with Sonos Connect and a free firmware update. After a simple set up, your Onkyo A/V receiver will seamlessly tie into Sonos, instantly waking, changing inputs and playing at the volume you command through the familiar Sonos app.

THX® Certified Select™ Theater-reference Audio

THX Certified Select guarantees theater-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 10 ft. (3 m) and volume 2,000 cubic feet (57 m3).

Dolby Atmos® and DTS:X™ at up to 7.2.4 Channels

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 and enjoy seamless top-to-bottom, side-to-side, and front-back coverage with four in-ceiling speakers and seven floor-standers. Individual sounds aren't tied to channels and move naturally around your audience.

Dolby® and DTS® Solutions For 3d Upmixing

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 works with the Google Assistant

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-RZ730 by voice.

Ready for DTS Play-Fi® Multi-room Audio Technology

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 synchronize music in every room.

Supports 4K HDR, BT.2020, 4K/60 Hz, 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.

AccuEQ Advance for 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 equalization.

AccuReflex

AccuReflex technology aligns the phase of up-firing "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object-based soundtracks.

Powered Sound In Three Zones

With a 5.2-ch theater 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* to be synced across rooms simultaneously, or a unique source to be played in every zone at once. Zone 2 and Zone 3 line-level outputs are ideal for sharing sources to existing hi-fi systems.

Manage Music with Onkyo Controller APP

Onkyo Controller app collects streaming services and network-attached audio into one interface. Select sources, control playback, and distribute audio.

Wi-Fi® and Bluetooth® Wireless Connectivity

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.

AirPlay, Streaming Services, And Internet Radio Built In

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

FlareConnect™ Wireless Multi-Room Audio

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.

Dynamic Audio Amplification (DAA)

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.

Onkyo's dynamic audio amplification delivers massive power at 225 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)/ 100 W/Ch (8 Ohms, 20 Hz-20 kHz, 0.08% THD, 2 Channels Driven).

Smooth Analog Signal

Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the audio signal to its original form following processing. Unlike conventional filters, VLSC removes pulse noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity for a smooth analog signal.

Limitless Performance. Installation Friendly.

The Onkyo RZ Series was designed for home theater integration and performance above and beyond your expectations. From multi-zone audio and video options to dedicated RZ Series phone support and a three-year product warranty, the Onkyo RZ Series delivers superior audio performance in the configurations you want with the support you should expect from the leader in home audio.
