The Onkyo TX-RZ70 AV Receiver is an 11.2-channel network receiver for an advanced 7.2.4 home cinema system. Eleven amplified channels can power this layout without a separate power amplifier. Built-in Dirac Live Full Bandwidth correction adapts the sound to the speakers and room. Seven HDMI inputs, three outputs and 4K/120 support connect cinema and gaming sources.
The Onkyo TX-RZ70 AV Receiver is an 11.2-channel network receiver designed for an advanced home cinema system. Its eleven amplified channels can power a complete 7.2.4 setup without requiring a separate power amplifier.
Amplification and audio formats
The stated amplifier rating is 140 W × 11 into 8 ohms, but the frequency range, distortion limit and number of simultaneously driven channels are not specified. This should not be interpreted as a promise of continuous 140 W output from every channel at the same time.
Room calibration
Built-in Dirac Live Full Bandwidth measures and calibrates the system for the connected speakers and the listening room. Dirac and Onkyo AccuEQ cannot operate simultaneously. Available under a separate licence, Dirac Live Bass Control is intended for calibrating one or more subwoofers.
Dirac correction is bypassed when a THX mode is enabled. THX modes are also unavailable while playing Dolby Atmos, DTS:X or Auro-3D content. Klipsch Optimize Mode applies a model-specific crossover setting for compatible Klipsch Reference and Reference Premiere speakers.
Video source connections
The receiver has seven HDMI inputs, including one on the front panel, and three HDMI outputs with eARC support. Compatible technologies and signals include 8K/60 Hz, 4K/120 Hz, Dolby Vision, HDR10+, HDCP 2.3, VRR, QFT and ALLM.
Discrete Zone 2 HDMI switching allows different Ultra HD sources to be used in two rooms. When two different sources are selected, 8K/60 is available only in Zone 1, while Zone 2 is limited to 4K/120.
Audio and legacy equipment connections
A dedicated RCA phono input accommodates a compatible turntable, while conventional line-level sources connect through the stereo RCA inputs. Two independent subwoofer outputs make it easier to configure a system with multiple subwoofers.
Networking and wireless audio
Chromecast built-in, AirPlay 2 and the listed music services operate through the home network. Service availability varies by country and may change. Two-way Bluetooth can receive audio from a source and transmit it to compatible wireless headphones.
Works with Sonos integration requires a separately purchased Sonos Port. Up to three Ports can be used, with one assigned to each independent zone.
Placement and setup
The receiver weighs 22 kg, so it needs a strong shelf, suitable ventilation and additional space behind the rear panel for cables to bend without strain.
Before completing the final calibration, update the receiver software so that the latest available fixes and feature updates are installed. Then select either Dirac or AccuEQ and take the measurements with the speakers in their final positions.

FAQ
Does a 7.2.4 system require an additional power amplifier?
No. The eleven built-in amplification channels can power the complete 7.2.4 layout. An external amplifier can be connected through the preamp outputs if the system is expanded.
Is Dirac Live Bass Control included as standard?
No. Dirac Live Full Bandwidth room correction is built in, but subwoofer management requires a separate licence for either one or multiple subwoofers.
How do I connect a games console?
Use an HDMI input and a compatible television. To use 4K/120, VRR or ALLM, the source, receiver, display and HDMI cable must all support the selected feature.
How much space should I allow inside the cabinet?
Choose a shelf that can safely support a 22 kg load. Allow room for air circulation and for the HDMI, speaker and other cables to bend behind the rear panel.
