The Onkyo TX-RZ70 is a flagship 11.2-channel (7.2.4 / 9.2.2) THX Certified Select AV Receiver, built to deliver a premium home theater experience. Boasting 140 Watts per channel of Class AB amplification, it provides robust power for dynamic audio. A key feature is the included Dirac Live Room Correction (Full Bandwidth), which precisely calibrates the audio to your unique room and speakers, revealing hidden detail and tightening bass. An optional Dirac Live Bass Control upgrade further refines subwoofer performance. Equipped with HDMI 2.1, the TX-RZ70 supports 8K/60Hz and 4K/120Hz video, along with HDR formats (Dolby Vision, HDR10+, HLG) and gaming enhancements like VRR and ALLM. It decodes all major immersive audio formats, including Dolby Atmos, DTS:X, IMAX Enhanced, and supports Auro-3D via firmware. Advanced streaming capabilities (AirPlay 2, Chromecast, DTS Play-Fi, Works with Sonos, Roon Ready) and Klipsch Optimize Mode complete this feature-rich receiver, making it a powerful and versatile hub for any high-performance home entertainment system.

Features

Studio Grade Processing
Built by and for audiophiles, but intuitively built for the everyman. Utilizing the very latest audio technology including ESS Sabre DACs, THX® Certification, and eARC functionality, the Onkyo TX-RZ70 overdelivers on premium home theater performance.

Dirac Live Technologies
You deserve an AVR that adapts to your life, not the other way around. With built-in Dirac Live® Room Calibration Full Bandwidth, the Onkyo TX-RZ70 uses machine learning to perfectly adapt and calibrate your audio settings to your unique speaker system and room layout. And big bass fans can upgrade their system with Dirac Live Bass Control Single/Multi Subwoofer for optimal calibration of the lowest tones.

IMAX Enhanced Mode
Bring the theater experience to your home by recreating IMAX content just as filmmakers intended. The TX-RZ70 meets the precise quality standards established by IMAX to reduce noise and grain to produce brighter, clearer pictures, plus immersive sound for the ultimate cinema experience. IMAX Enhanced Mode also provides a stretched aspect ratio for up to 26% more picture on your screen.

THX Certified
In 1993, Onkyo became the first consumer home theater electronics brand to be THX-certified, after thousands of tests. No matter what input is used, what combination of built-in features are used, what preamplifier or amplifier, there can be absolutely nothing added, nothing taken away from the source material. And the TX-RZ70 offers four distinct THX listening modes: cinema, gaming, music, and surround EX.

Klipsch Optimize Mode
Klipsch and Onkyo teamed up to implement the precise crossover values for specific new speakers, so you can easily and seamlessly integrate your Klipsch Reference and Reference Premiere speakers with your new Onkyo AVR. Simply select the model of speaker for each channel, and the optimized crossover setting will be automatically applied.
