Surround:AI

     This artificial intelligence analyzes the DSP parameters and optimizes the surround effect of distinct sound elements such as background music, dialogue, and sound effects. It's like having a professional sound engineer tune the sound according to the scene. 64-bit processing is achieved with the Qualcomm QCS407.

Crafted for Clarity

     The newly designed Anti-Resonance Technology (A.R.T.), H-shaped cross frame, and mechanical structure are a rock-solid defense against internal and external vibrations that affect the sound. Experience crystal-clear sound that moves you, all while your A/V receiver stays perfectly still.

High-Quality Digital Components

     The Qualcomm QCS407 takes the receiver's surround sound to the next level with support for Dolby Atmos and DTS:X. With the ESS SABRE ES9007S Premier Audio DAC, you get extraordinary signal-to-noise ratio and up to 120 dB of dynamic range for professional quality audio.

Cinema DSP HD3

     This unique Yamaha proprietary sound field playback technology was created by combining actual measured sound field data with cutting-edge digital signal processing technology. The revamped CINEMA DSP HD3 features new signal processing algorithms and maximizes sound effects, accurately reproducing a new dimension of realism.
