    The immersive audio format of DTS:X can naturally present sound effects in its corresponding space, thereby producing a lifelike listening effect. DTS Neural:X™ brings a higher level of immersion and presence to all your favorite movies.

    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.

    When music is encoded into a digitally compressed format such as MP3, the frequencies are damaged. Yamaha's music compression enhancer uses an elegant digital signal processor to restore the lost content with an exclusive actuarial program, allowing the music to maintain its original quality.

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

    Workmanship quality

    ART Anti-Vibration Technology (Anti Resonance Technology), a fifth wedge-shaped foot is set in the center of the bottom of the fuselage. It reduces vibrations caused by power transformers, power transistors, heat sinks, and speaker sounds—showing dynamic sound effects and accurately reproducing the original sound.

    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.

    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.
