When music is encoded into a digitally compressed format like MP3, the frequency response suffers. Yamaha’s Compressed Music Enhancer employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should.

HIGH QUALITY PARTS

High Slew Rate Amplifier

The slew rate measures how quickly an amplifier can respond to a rapid change of input level, which contributes to delivering a precise signal transmission and is especially effective with high resolution audio signals. This newly designed circuit achieves both a high slew rate and stable signal transmission, allowing it to handle each audio signal with precision and accuracy.

High-Quality Digital Components

The Qualcomm® QCS407 is designed to provide truly superior audio performance, with support for Dolby Atmos and DTS:X immersive home audio, as well as a dedicated high-performance audio DSP.

It features ESS’s state of the art 32-bit SABRE PRO Premier DAC ES9026PRO. ESS’s patented 32-bit Hyper Stream, Total Harmonic Distortion (THD) compensation function works to minimize noise levels. In combination with the Yamaha original D.O.P.G. (DAC On Pure Ground) concept, which eliminates the potential difference between audio circuit stages to reduce ground noise, it dramatically enhances silence and resolution over the entire audio range for rich and expressive reproduction of even the most delicate sounds.

CRAFTSMANSHIP

Anti-Resonance Technology Wedge

The Anti-Resonance Technology (A.R.T.) Wedge is a fifth foot in the center of the chassis unit base. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers — providing dynamic sound and focused, accurate reproduction.

Newly Designed Mechanical Structure

The highly logical and symmetrical internal layout of parts and totally renewed circuit boards are designed to keep the signal paths on each board as short as possible. The new H-cross frame improves rigidity of the receiver body and sound stability, allowing for clearer, sharper and more transparent reproduction. Also the newly redesigned mechanical structure contributes to avoiding the transition of vibration from the transformer to the amplifier circuit. Sound noises are reduced to improve clarity.

MOVIES AND GAMES LIKE NEVER BEFORE

HDR and HDR10+*

HDR (high dynamic range) video provides incredible contrast, smooth tone and rich, bright colors—giving you full, high-definition enjoyment with an exceptionally realistic and natural picture quality.

HDR10+ greatly improves dynamic range (the ratio of light to dark) of video content on a scene-by-scene (or even frame-by-frame) basis. Also, using frame-by-frame metadata, it improves the scene characteristics between bright and dark so that important detail can remain. This enables displays to reproduce images more realistically, adhering to the creator's intent.

* HDR10+ is available via a future update
