Enjoy UHD, HDR, and 3D support via HDMI with the Onkyo TX-RZ730 9.2-Channel Network A/V Receiver. It produces up to 100W of power per channel at 8 Ohms for room-filling sound. AccuEQ Advance sound calibration allows you to tailor the sound to your room's specific acoustics.

Built-in Bluetooth connectivity lets you listen to music wirelessly from your favorite Bluetooth-capable devices, while built-in Wi-Fi connectivity provides access to your Spotify, TIDAL, and other online services. Chromecast built-in enables the receiver to be controlled with your voice with your Google Assistant-enabled device. The TX-RZ730 is equipped with seven HDMI inputs and two HDMI outputs. One of the HDMI outputs supports ARC for the reproduction of TV-based audio, such as your TV's built-in apps.

Access to certain Internet-based content may require a subscription to a service. Not all services are available in all areas.

THX Certified Select Theater-Reference Audio

THX Certified Select virtually guarantees theater-reference sound in your home. To gain certification, amplifiers must pass bench tests covering every aspect of performance. THX Certified Select components are designed to suit rooms where the screen-to-seat distance is about 10' and volume 2000 cubic feet.

Engineered for Quality

The TX-RZ730 uses a custom high-current transformer and block capacitors, among other premium parts, to deliver a 5 Hz to 100 kHz frequency response range for enhanced bass, treble, and dynamics. The TX-RZ730 supports a variety of home theater and multi-room layouts to suit you, while details such as a 12 V trigger, RS-232 port, IP control, and IR input help simplify home integration.

Dynamic Audio Amplification (DAA)

Dynamic Audio Amplification places less emphasis on lab measurements and more on how the sound feels in real life. High-current architecture and fine-tuning help deliver natural transient response, the key to lifelike sound. This reserve of power is designed to arrive instantly when action happens on the screen, which helps to create a more exciting movie experience. Control is maintained with the transformer and capacitors, non-phase-shift amp circuitry, and discrete output transistors. Rated to drive up to nine four-ohm speakers simultaneously, and with VLSC (Vector Linear Shaping Circuitry) digital noise filtering for source-faithful clarity, DAA helps provide sound with both power and sensitivity.

Dolby Atmos and DTS:X at up to 7.2.4 Channels

With 7.2.2-channel or 5.2.4-channel Dolby Atmos and DTS:X compatibility, individual sounds aren't tied to a specific channel and seem to move above and around you with enhanced realism. Connect an outboard power amp via the 11.2-channel pre-outs for virtually seamless front-to-back, side-to-side, and floor-to-ceiling coverage with four in-ceiling speakers and seven floor-standers.

Dolby & DTS Solutions for 3D Sound

DTS Neural:X technology and Dolby Surround are designed to find spatial cues in legacy soundtracks and upmix them for playback through speaker systems with height channels. Since these decoding options are cross-compatible with other sound formats from Dolby and DTS, you can enjoy spatially realistic sound from your existing DVD and Blu-ray library, or via a movie streaming service.

Chromecast built-in Works with the Google Assistant

Stream music from your compatible smartphone, laptop, or computer to the receiver. Control playback with Chromecast-enabled apps from your iOS or Android phone or tablet, Mac or Windows computer, 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 music from your online services, media server, and mobile device to any number of compatible products using the 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. Multi-room functionality requires additional equipment.

FlareConnect Wireless Multi-Room Audio

FlareConnect shares audio from network and external audio input sources between compatible components. Enjoy simple multi-room playback of 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.

Powered Sound in Three Zones

With a 5.2-channel layout in Zone 1, the remaining four channels can drive speakers in Zone 2 and Zone 3. Along with analog distribution, dedicated DACs enable digital sources (except HDMI and S/PDIF audio in Zone 3) 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 well suited for sharing sources to an existing hi-fi system.

AccuEQ Advance Sound Calibration

AccuEQ sets speaker distance, SP level, and crossover. In addition, AccuEQ Advance employs multipoint 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 help ensure accurate equalization.

Wi-Fi and Bluetooth Wireless Connectivity

Built-in dual-band 5 / 2.4 GHz Wi-Fi helps provide network stability for streaming, the Onkyo Controller app, and multi-room audio. Bluetooth wireless technology is also on-board for simplified mobile or laptop connection.

AirPlay, Streaming Services, and Internet Radio Built-In

Music lovers have easy access to their iTunes library. Find and stream music from your iPad, iPhone, Mac, and Windows computer over the Apple AirPlay wireless audio platform. Additionally, Amazon Music, Spotify, TIDAL, Deezer, Pandora, and TuneIn are all built into the system GUI, making selection easy using the Onkyo Controller or the Onkyo Music Control app.

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

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.
