Sound improvement for digitally compressed music (Compressed Music Enhancer)

When encoding music into a digital, compressed format, such as MP3, the frequency response is affected. Yamaha's Compressed Music Enhancer uses exclusive algorithms in digital signal processing that restore lost quality. This way the music sounds the way it should! Fresh and balanced.

Advantages of high slew rate amplifiers

A new circuit that doubles the slew rate produces precise signal transmission and is particularly suitable for high-resolution audio signals. Often, high slew rate amplifiers cause unstable signal transmission, but Yamaha's newly developed circuit achieves a high slew rate with stable signal transmission.

High-quality digital components are built into the Yamaha RX-A4A

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

The Yamaha RX-A4a uses the SABER ES9007S Premier Audio DAC to achieve professional sound reproduction of digital audio signals with an exceptional signal-to-noise ratio and a dynamic range of up to 120 dB.

Wedge with anti-resonance technology

The newly developed Anti Resonance Technology (ART) wedge forms a fifth foot in the center of the chassis base. This dampens much more of the vibrations generated by power transformers, power transistors and heat sinks, as well as the vibrations that can be caused by the sound emitted by the speakers, providing dynamic sound and focused, precise reproduction.

Redesigned mechanical structure in RX-A4A

The highly logical and symmetrical internal layout of components and completely redesigned boards are designed to keep the signal paths on each board as short as possible. The new H-cross frame improves the rigidity of the receiver body and sound stability, enabling clearer, sharper and more transparent reproduction.

In addition, the newly designed mechanical structure helps to avoid the transfer of vibrations from the transformer to the amplifier circuit. Noise is reduced to improve clarity.

HDR10+*

HDR10+ not only stands for a dynamic spectrum (light-dark ratio) in video content from scene to scene (or even from frame to frame). With a small amount of metadata, it also represents the scene characteristics between light and dark, preserving important details. This allows the images - and therefore the filmmaker's intentions - to be reproduced more realistically on the screen.

* This feature is available via firmware update.

8K/60 Hz, 4k/120 Hz possible with RX-A4A

Supports end-to-end 8K/4K resolutions and higher refresh rate solutions with a single redesigned cable for seamless integration into the HDMI ecosystem. 8K creates a super-immersive moving image with twice the horizontal and vertical resolution of 4K and four times as many pixels.

In combination with the refresh rate of 60 Hz, the result is a smooth, sharp motion image even when changing images quickly. Thanks to 4K/120 Hz, ultra-fast moving images in UHD can be reproduced with high contrast and razor-sharp, making sports, action films, high-performance gaming systems and VR much more pleasant to watch.

* This feature is available via firmware update.

The Yamaha RX-A4A offers special gaming functions (ALLM, VRR, QMS, QFT)*

The expanded gaming and media functions ensure even more seamless movements and transitions when playing games, films and videos. The Auto Low Latency Mode (ALLM) enables the ideal latency to be automatically set for a smooth, delay-free and uninterrupted motion image with interactivity. Variable Refresh Rate (VRR) reduces or eliminates lag, stuttering images and screen tearing to create a smooth, detailed gaming experience.

Quick Media Switching (QMS) for movies and videos eliminates delays that can result in black screens before content playback. Quick Frame Transport (QFT) reduces gaming latency to enable smooth, lag-free gaming with real-time interactive VR.
