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.
