With 7 HDMI 2.1 inputs and 3 outputs (including a dedicated Zone 2 output), the TX-RZ70 gives you the connectivity to run a sophisticated home audio, theater, and gaming system.

You deserve an AVR that adapts to your life, not the other way around. With built-in Dirac Live® Room Correction Full Bandwidth, the TX-RZ70 uses advanced measurement and machine-learning algorithms to perfectly adapt and calibrate your audio settings to your unique speaker system and room layout. Big bass fans can also upgrade their system with Dirac Live Bass Control on multiple subwoofers, for optimal calibration of the lowest tones.
In 1993, Onkyo became the first consumer home theater electronics brand to be THX-certified. The TX-RZ70 carries that legacy forward with THX Select certification and four dedicated THX listening modes: Cinema, Gaming, Music, and Surround EX. No matter what input or combination of features you use, nothing is added and nothing is taken away from the source material.
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 for brighter, clearer pictures, paired with 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.
Dolby Atmos®, DTS:X®, and Auro-3D® formats allow engineers to map sound anywhere in 3D space, effects moving from speaker to speaker all around the room and wrapping your audience in the latest films and games. With 11 channels of onboard amplification, you can run a full 7.2.4 immersive layout without external amps. Dolby Surround® and DTS® Neural:X find overhead cues in legacy soundtracks and upmix for awesome spatial realism.
This receiver can join your existing Sonos Home Sound System, or be the start of a new one, just by pairing it with a Sonos Port.* This Works With Sonos Certified AVR offers a best-in-class tie-in to the Sonos ecosystem, waking, changing inputs, and playing at the volume you want using the Sonos Volume-Pass Through feature from the Sonos app. The TX-RZ70 can work with up to three Sonos Ports — one for each of three independent zones — each playing a completely different stream.
Klipsch and Onkyo teamed up to implement the precise crossover values for specific Klipsch Reference and Reference Premiere speakers. Simply select the model of speaker for each channel, and the optimized crossover setting will be automatically applied — no guesswork, no manual tuning.
Access to Spotify®, TIDAL, Deezer, TuneIn, Pandora®, Apple AirPlay 2, and Chromecast built-in are baked into the system. Use dedicated apps (where available) or the free Onkyo Control App for Apple and Android devices to find and play music. Roon Ready certification rounds out a streaming feature set built for serious listeners.
DTS Play-Fi allows you to enjoy high-quality music from connected online services, networked media servers, and your device library over Wi-Fi® to any number of compatible products using the Onkyo Music Control App for iPad, iPhone, and Android smartphones/tablets. Each member of your family can use their own device to listen to their music in a room or group of rooms, structuring a comprehensive multi-room ecosystem that satisfies virtually any need.
Set up different UHD entertainment options in up to three independent zones — watch a movie in the home theater while the kids enjoy cartoons in another room and music streams in a third. Zone 2 HDMI switching means high-resolution video isn't confined to the main listening space.
Refined over 70 years to deliver emotion in high fidelity, DAA features a custom High-Current Low-Noise Power Transformer, customized capacitors, and discrete Class AB amp output stages.
