Welcome to Ultra HD 8K with the Latest HDMI

The HDMI 2.1 standard offers a multitude of features, such as transmitting 8K/60p signals to a compatible screen. HDR10 and HLG, HDR10+, and Dolby Vision formats optimize the image by adjusting brightness, contrast, and colors frame by frame. HDCP 2.3 is supported by all HDMI terminals, while the main eARC output allows multichannel audio (including Dolby Atmos or DTS:X) to be transmitted from the TV to the amplifier for decoding and amplification. Additionally, the QMS (Quick Media Switching) function reduces the blank screens that can occur when changing HDMI sources.

IMAX Enhanced Mode

Recreate the theatrical experience in the comfort of your home by reproducing IMAX content as the filmmakers intended. The TX-RZ70 meets the strict quality standards set by IMAX to reduce noise and grain, producing brighter and clearer images, as well as immersive sound for the ultimate cinematic experience. IMAX Enhanced mode also offers a stretched aspect ratio, allowing up to 26% more image on your screen.

THX Certified

In 1993, Onkyo became the first consumer electronics brand for home theater to achieve THX certification after passing thousands of tests. Regardless of the input used, the combination of built-in features, the preamplifier, or the amplifier, there can be no alteration or suppression of the source material. The TX-RZ70 also offers four distinct THX listening modes: cinema, gaming, music, and surround EX.

Superb amplifier, recommended for a 7.2.4 Klipsch setup, it does the job perfectly.
Control via the mobile app or full programming through a computer is just excellent. I recommend it!

Superbe Ampli, conseillé compte tenu d'une configuration 7.2.4 Klipsch, il fait parfaitement le travail.
Le pilotage via l'application mobile ou encore la programmation complète via un ordinateur est juste superbe. Je recommande!

Very good product, works very well in 5.1 with Klipsch speakers. A big advantage is Dirac Live for adjusting the sound.
