The High-Current A/V Hub That Makes Life Better

Dynamic Audio Amplification has upgraded parts for earthquake bass and flawless treble: check out the 5Hz – 100kHz frequency response.

Introducing the Premium Onkyo RZ Series

Onkyo's RZ Series takes performance and build quality to the next level for a reference-level experience. The custom high-current transformer, block capacitors, and other upgraded parts deliver 5 Hz–100 kHz frequency response for wall-shaking bass, clean treble, and fast dynamics. The RZ Series supports a variety of home theater and multiroom layouts to suit you, while details such as 12 V trigger, RS-232C, IP Control, and IR input make home integration easy.

Dynamic Audio Amplification

The design philosophy behind Dynamic Audio Amplification places less emphasis on lab measurements and more on how the sound feels in real life. Unique high-current architecture and expert tuning deliver natural transient response, the key to life-like sound. This deep reserve of power arrives instantly when action explodes on screen, adding pure adrenaline to the film experience. Control is maintained with custom transformer and huge block capacitors, non-phase-shift amp circuitry, and discrete output transistors. Rated to drive nine four-ohm speakers simultaneously, and with patented VLSC digital noise filtering (Front L/R) for source-faithful clarity, DAA has muscle and sensitivity for emotionally compelling sound.

Dolby Atmos and DTS:X Without Compromise

Experience Dolby Atmos and DTS:X soundtracks as they were meant to be felt, with complete coverage assured through 5.2.4 or 7.2.2-ch speaker layouts. Individual sounds aren’t tied to a specific channel and move in space above and around your audience with life-like realism.

Dolby and DTS Solutions for 3D Sound

DTS Neural:X technology and Dolby Surround find spatial cues in legacy soundtracks and upmix for playback through speaker systems with height channels. Cross-compatible with popular sound formats from Dolby and DTS, you can enjoy seamless front-to-back, side-to-side, and floor-to-ceiling coverage with your existing DVD and Blu-ray Disc library or video 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-RZ630 by voice.

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 line-level output is ideal for sharing sources to an existing Hi-Fi system.

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.

Ready for DTS Play-Fi Multiroom 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, and family members can use their own device to listen in a room or group of rooms.

FlareConnect Wireless Multiroom 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.

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.

Manage Playback with Onkyo Controller

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

AirPlay, Streaming Services, and Internet Radio Built In

Music lovers have easy access to their iTunes library. 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.

Supports 4K HDR, BT.2020, 4K/60 Hz, and HDCP 2.2

Welcome film-like 4K video bursting with the 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.

Really nice sound & features!
First, the sound is really great. There are 3 equalizer settings that can be set up, plus there is a simple bass/treble tone control that can be used in addition to or instead of the equalizer. This is good for temporary adjustments such as to compensate for a higher or lower bass level on a particular song without changing your equalizer settings.

Second, some of the great features include Bluetooth and the support of internet apps like Pandora and Amazon Music. A “Mini Player” feature allows for you to shrink down the internet app to 2 lines at the bottom of the screen while you watch baseball or football, for example, on the TV.

There are many sound modes such as 4-channel stereo and Dolby including Atmos support. Also, there is built-in Chromecast audio support to cast music from your cell phone or tablet.

So far, I'm satisfied and pleased with my purchase. I'm adjusting to user interface after having Yamaha for many years. Only had it for a week, so we'll see about dependability.

Love this receiver. So many features.
My only complaint is that the provided paperwork is somewhat lacking. I recommend downloading the pdf manual as it is much better.

Upgrade to Atmos and DAC for Zone 2 - the latter is the most important so that digital inputs into the receiver are able to be passed on either in HDMI or RCA line level through Zone 2 to another receiver to power whole home speaker system.

What does that mean when the company rates this can play up to 6 ohm? Can I hook up 8 ohm speakers up to this receiver?
A shopper on Aug 23, 2019
  Manufacturers typically rate the minimum speaker impedance the amplifier can drive. The Onkyo will easily drive a speaker rated 8 ohms.
Will this support 4 to 8 obms?
William D on Jun 20, 2019
  The manufacturer rates this receiver's down only to 6 ohms.
does this receiver support airplay2?
A shopper on Mar 27, 2019
  The receiver supports Airplay but not Airplay2
