Unparalleled sound effects

This original Yamaha sound field creation technology is created by combining actual measured sound field data and digital signal processing technology. Yamaha collects sound field data from the world's leading concert halls and music performance clubs, leveraging its extensive experience in concert halls, public spaces and mixing fields. Digitize and integrate huge information database into dedicated LSI devices. Through home theater equipment, the sound field of the concert hall space is accurately reproduced, allowing you to experience the immersive presence and shocking theater sound effects.

This will help with accurate signal transmission, especially for high-resolution audio. Usually, high slew rate amplification causes unstable signal transmission, but Yamaha's newly designed circuit can achieve high slew rate with stable signal transmission.

When music is encoded in a digitally compressed format, such as MP3, frequency response is affected. Yamaha's Compressed Music Enhancer uses sophisticated digital signal processing with exclusive algorithms to repair lost data, keeping the played music as it should be.

Unprecedented movie and game experience

HDR10+ signals not only signal the dynamic range (ratio of light and dark) of video content on a per-scene basis (or even per-frame), but also provide scene characteristics between light and dark with a small amount of metadata to preserve important details. This allows the display to more faithfully reproduce the image as intended by the creator.

*This feature requires a firmware update.

Supports end-to-end 8K/4K resolution and higher refresh rate image quality, and can be seamlessly integrated through an upgraded single HDMI cable. 8K has twice the horizontal and vertical resolution of 4K and has 4 times the pixels; combined with a 60Hz update rate, you can watch high-speed action content smoothly and clearly. 4K/120Hz allows UHD images with ultra-fast motion to achieve a clear and sharp viewing experience; making sports events, action movies, high-performance games, and VR entertainment experiences smoother.

*This feature requires a firmware update.

Enhanced gaming and multimedia functions, effectively improving the smoothness and transition effects of games, movies and videos. Enhanced features include: Auto Low Latency Mode (ALLM) automatically sets the ideal latency mode for smooth, lag-free and uninterrupted viewing and interactivity. Variable Refresh Rate (VRR) can reduce or eliminate delays, interruptions and screen tearing, creating a smoother and more detailed gaming experience. Quick Media Switching (QMS) is specially designed for movies and videos to eliminate blank screen delays before content is played. Quick Frame Transport (QFT) reduces latency issues, enabling a smooth gaming experience and an instant interactive virtual reality experience.
