Best-in-class movie realism with THX Certified Select Image

Best-in-class movie realism with THX® Certified Select™

THX Ltd. was founded by legendary filmmaker George Lucas to improve the entertainment experience at commercial theaters and at home. To gain THX Certified Select certification, home theater receivers must pass 2,000 severe THX laboratory bench-tests in 75 categories covering 14,000 data points to assure reference performance in every respect. With uncompromising sound-quality exceeding world-class standards, you can feel theater sound as the filmmaker intended.

High current. Thrilling dynamics. Image

High current. Thrilling dynamics.

Dynamic Audio Amplification delivers emotionally rich sound for real, not just on paper. Based on our high-current amplification philosophy, the design leverages accurate power stability for superior speaker control. Massive customized transformer and two custom 15,000 μF capacitors featuring vibration-resistant coiled sleeves enable instant transient response for thrilling audio reproduction. Capacitors are connected to the power amps via high-conductivity copper bus plates, which serve as a solid and stable base for the amp circuitry. Any part not up to standard is fabricated and tested in-house. The result is pure musical dynamism that defines our sound.

Detailed, nuanced, noise-free sound Image

Detailed, nuanced, noise-free sound

Vibration has a significant impact on sound. To help eliminate it, the TX-RZ830 features a thick extruded aluminum heat sink that controls the length and pitch of resonance frequencies. The heat sink cools discrete power transistors at the heart of the system and is attached to the chassis with copper screws, the highly rigid structure preventing noise transmission from the transistors into adjacent circuitry. The chassis is coated in special black paint that helps to reduce subtle surface vibrations and contributes to smooth and clear audio reproduction.

Precision AKM (AK4458) 384 kHz/32-bit DAC Image

Precision AKM (AK4458) 384 kHz/32-bit DAC

Central to achieving such powerful yet nuanced sound is the TX-RZ830’s digital circuit board, which features radically reduced signal-path lengths to minimize the chance of noise and playback errors. The digital audio board includes AKM’s acclaimed AK4458 384 kHz/32-bit D/A converter, a device noted for its low out-of-band noise and excellent S/N performance. Two 384 kHz/32-bit DACs from Texas Instruments complement the main DAC, while two 32-bit DSPs perform bit-perfect decoding for the latest audio formats.

AccuEQ Advance for Accurate Calibration Image

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.

Freedom to tailor your entertainment lifestyle Image

Freedom to tailor your entertainment lifestyle

With 9.2 channels of amplification to play with, you can choose a home entertainment layout that maximizes enjoyment of daily life. Get the full Dolby Atmos® and DTS:X® experience through a 5.2.4-ch or 7.2.2-ch layout; distribute amplified stereo signals to pairs of speakers in Zone 2 and Zone 3 with a 5.2-ch surround-sound setup in the main room; or select a 5.2.2-ch speaker layout in the theater room with powered audio for Zone 2—just add speakers and use Onkyo Controller to control playback from anywhere.

Dolby Atmos and DTS:X at up to 7.2.4 channels Image

Dolby Atmos® and DTS:X® at up to 7.2.4 channels

Enjoy state-of-the-art Dolby Atmos and DTS:X movie and game soundtracks through 7.2.4 channels with a stereo amp connected via 11.2-multichannel pre-outs. Get more seamless coverage through a 7.2.2 or 5.2.4 channel layout. Be at the center of the movie with complete top-to-bottom, side-to-side, and front-back coverage provided by in-ceiling speakers and floor-standers. Individual sounds aren’t tied to channels and move naturally around your audience. Furthermore, cross-compatible Dolby Surround and DTS Neural:X™ upmixing solutions can remap legacy soundtracks encoded on DVD, Blu-ray Disc™, and streaming video for spatial playback through any speaker layout.

A wider choice of wireless multi-room platforms with stable 5 GHz/2.4 GHz Wi-Fi connection Image

A wider choice of wireless multi-room platforms with stable 5 GHz/2.4 GHz Wi-Fi® connection

The TX-RZ830 features DTS Play-Fi® technology to share high-quality music from connected online services, media servers, and your device library to any number of compatible products using the Onkyo Music Control App for iPad, iPhone, and Android™ smartphones/tablets. DTS Play-Fi technology easily synchronizes music playback in every room. With Chromecast built-in, you can stream any music from your smartphone, laptop, or PC to the TX-RZ830 and other supported components via Chromecast-enabled apps you know and love from your iPhone, iPad, Android phone or tablet, Mac or Windows laptop, or Chromebook™.

Works with Sonos Image

Works with Sonos

Welcome your new A/V receiver into the Sonos Home Sound System family—just pair it with a Sonos Connect and let Onkyo sound join the party. “Works with Sonos” means a product is designed to fit seamlessly into the Sonos ecosystem, and will wake from standby, switch inputs, and commence playback at your desired volume whenever selected from the Sonos app. Just by adding a Sonos Connect, you upgrade the streaming capabilities of your Onkyo home theater, and thanks to RCA and optical/coaxial digital audio outputs, both setup flexibility and sound quality are outstanding. The Sonos app, meanwhile, gathers all your favorite streaming sources into one beautiful interface so you can orchestrate entertainment all over the home. Even guests can join in by installing the Sonos app on their devices.

*Note: Requires a free firmware update. Sonos Connect sold separately (includes RCA cable). Sonos app is available free from App Store or Google Play.

FlareConnect technology expands enjoyment of music Image

FlareConnect™ technology expands enjoyment of music

FlareConnect shares audio from network and external audio input sources between supported components. Connect your audio systems to Wi-Fi to enjoy high-quality reproduction of music stored on mobiles using Onkyo Controller app on single or grouped speakers. Relax with a huge variety of music via streaming services and internet radio channels. You can also play from any component’s external audio inputs. Your favorite tunes, even LPs, can be mirrored on speakers in other rooms. Music selection, speaker grouping, and playback are built into the Onkyo Controller app. For external input availability, click here.

Pure Audio Mode shows the soul of your music Image

Pure Audio Mode shows the soul of your music

Enjoy the personality of your Front L/R loudspeakers in Pure Audio Mode, a selectable playback environment that’s designed to preserve original signal integrity by shutting down sources of potential interference. Pure Audio Mode complements the TX-RZ830’s short-signal-path design by powering-off all non-essential circuitries, such as the front-panel display and analog video circuitry, to reduce interference and enable pristine reproduction of audio sources including LPs, CDs, and Hi-Res Audio.

Custom fan for whisper-quiet cooling Image

Custom fan for whisper-quiet cooling

Details such as the custom-fabricated cooling fan reveal the lengths we go to in preventing noise from compromising audio fidelity. The fan’s resin base dampens resonance while rubber cushions and felt pads absorb vibrations before they can enter the chassis. Fan housing features a unique structure that eliminates need for bracing and associated squeal. The fan itself has wide blades designed for effective yet whisper-quiet cooling at low speeds.
