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.
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 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
Vibration has a significant impact on sound. To help eliminate it, the TX-RZ730 features a thick extruded aluminum heat sink that controls the length and pitch of resonance frequencies by design. Further, the high quality of components and parts used throughout the receiver contributes to its heft. Heavy weight and high strength work with robust feet in the furthest corners of the chassis, where rigidity is highest, to virtually wipe out vibrations that cause distortion. Together, these aspects of build quality contribute to smooth high-fidelity performance.

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
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.

A wider choice of wireless multi-room platforms with stable 5 GHz/2.4 GHz Wi-Fi® connection
Built-in Wi-Fi supports 5 GHz and 2.4 GHz frequency bands so your components can connect to the channel with the least amount of congestion. Stable connectivity delivers a more satisfying multi-room experience on your choice of network audio platform. The TX-RZ730 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-RZ730 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™.

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.

Spectacular 4K HDR with BT.2020, 4K/60 Hz, and HDCP 2.2
HDR reveals what’s been missing from high-definition video with improved detail resolution in shadows and sparkling highlights as the eye sees them naturally. HDR also expands the color gamut to about 75 percent of the visible color spectrum. Colors are infinitely richer and more natural on HDR-compliant TVs, with smoother tonal gradation. The TX-RZ730 has seven HDMI inputs, Main Out, and Sub/Zone 2 Out to support pass-through of 4K HDR video in HDR10, HLG, and Dolby Vision™ formats. Selected inputs handle the BT.2020 4K Video Standard, 4K/60 Hz video, and unlock HDCP 2.2-protected premium content.

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.

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.

Enrich life with a wider choice of music streaming services, internet radio, audiobooks, and more
Amazon Music can be easily accessed via Onkyo Music Control App, and TIDAL, TuneIn, Deezer, and Spotify with Onkyo Controller (note a service subscription may be required). Install the Onkyo apps on iPhone or Android™ devices to perform different operations, such as switching inputs, selecting music, and controlling volume. The remote app also lets you cue and play music in Zone 2. You can play the same source in both rooms or different sources in each. Network Standby powers up the sleeping receiver for playback using the remote app. Visit App Store or Google Play to download free.
