    With SURROUND:AI, the AI ​​integrated in the DSP creates a surround sound effect for the content scene. Instantly analyze scenes, focusing on sound elements such as dialogue, background music, ambient sounds and sound effects, and automatically optimize surround sound effects in real time. It's like hiring a professional sound engineer to adjust the sound according to the real-time scene changes to create a realistic sense of reality. And Qualcomm® QCS407 features 64-bit high-precision processing to deliver precise surround sound.

    Designed for movies, music and games CINEMA DSP 3D

    Yamaha's flagship 3D sound field technology is created by combining measured sound field data with digital signal processing. The improved CINEMA DSP HD3 features new signal processing algorithms and drastically improves cinema sound effects, accurately reproducing a new dimension of sound field realism with rich presence and borderless sense. By using front, center and surround speakers to create rear virtual speakers, CINEMA DSP HD3 can play up to 11.1 channels* even when using a 7.1 channel speaker configuration.

    *Requires connection to Front Presence Speaker

    Dolby Atmos® with Height Virtualizer (virtual overhead sound effect)

    If your theater system does not have ceiling speakers or front overhead speakers, you can still simulate the Atmos experience through Dolby Atmos' Height Virtualization Technology. Configure five speakers to create the effect of two in-ceiling speakers, or use all seven channels to simulate the powerful effect of four in-ceiling speakers.

    Enjoy the stunning surround effects of a 5.1 surround speaker system with two in-ceiling speakers or two Dolby Atmos reflective speakers—including classic content with Dolby Surround Upmixer.


    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.


    The magic of AURO-3D® technology is its ability to transform any space and any content. AURO-3D will deliver a purer, breathtaking immersive audio experience every time. AURO's unique vertical stereo field allows sound to travel throughout our daily lives, ensuring powerful soundscapes that transport us into the world of our chosen content.

    Hear more and feel more with AURO-3D.

    Compressed music enhancement device

    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.

    High quality parts

    High Conversion Rates Expand Advantages

    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.

    High quality components

    Qualcomm® QCS407 is designed to provide truly outstanding audio performance, supporting Dolby Atmos and DTS:X immersive cinema effects, using a dedicated high-performance audio DSP chip and ESS's advanced 32 SABER PRO Premier DAC S9026PRO chip. ESS's patented 32-bit HyperStream, total harmonic distortion (THD) compensation function can reduce noise levels to an even lower level. At the same time, the updated design of the transformer part and the dual current and voltage shunt technology make the power supply purer and achieve professional-quality audio.


    Redesigned fifth foot position

    The representative fifth pin that guarantees high-quality sound quality has been scientifically redesigned to meet the changes in the position of the transformer and in order to meet higher earthquake resistance requirements. Moving to the front of the amplifier to a better position reduces the vibration of the chassis to an almost unmeasurable value, making the sound imaging more realistic and the sense of low-frequency control enhanced. Brass is also added to the "fifth foot" of the RX-A8A.

    Brand new structure

    The newly designed anti-resonance technology (ART), H-shaped cross frame and mechanical symmetry structure, compared with the previous generation, double the anti-deformation ability, have a solid defense effect on the internal vibration of the machine that affects the sound quality, and can maintain the stability of the audio-visual amplifier of static. The 4-layer preamplifier circuit design achieves stable low impedance and signal transmission, allowing you to experience clear 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.

    *Will be updated via Firmware

    8K/60Hz, 4k/120Hz*

    Supporting 8K/4K resolution and higher refresh rate solutions, only one upgrade cable is needed to achieve seamless integration in HDMI energy-saving mode. 8K provides an ultra-immersive viewing experience, with twice the horizontal and vertical resolution and four times the pixels of 4K; coupled with a 60Hz refresh rate, content can be viewed smoothly and clearly under high-speed operation. 4K/120Hz can make fast-motion UHD images clear and sharp, making the entertainment experience of sports programs, action movies, and high-performance games smoother.

    *Will be updated via Firmware

    Game-specific functions (ALLM, VRR, QMS, QFT)*

    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.

    *Will be updated via Firmware

    Designed for your space

    YPAO™-RSC (with 3D, Multi-Point Measurement and 64-bit High Precision EQ)


    Calibrate room sound by analyzing the room's sound field and measuring speaker characteristics. This feature also optimizes sound parameters to take full advantage of the outstanding performance of CINEMA DSP, Dolby Atmos® and DTS:X®. Provides a new YPAO low-frequency mode to solve the problem of low-frequency standing waves, conforms to the acoustics of the living room, and makes the shock feel everywhere.

    Compatible with wireless rear speakers

    An audio-visual amplifier and MusicCast 50 or MusicCast 20 wireless streaming speakers, combined with wireless rear speakers, can give you a top-notch home theater experience. On top of that, you can enjoy realistic sound effects with a clean and simple setup. Quickly turn your current living room into an audio-visual entertainment place where you can watch movies and listen to music.

    Attractive design

    Yamaha's precise design and craftsmanship result in masterpieces of visual and acoustic art.

    The thick chassis design can stabilize the overall body structure and produce the best sound effects. The beautiful appearance can show the uniqueness of AVENTAGE and further enhance its authority in the field of acoustics.

    AVENTAGE combines classic elements with the latest designs, demonstrating innovative and high-quality engineering technology.

    SCENE function key, with preset song and radio functions

    There are four SCENE function keys in total. You can preset these to different output and sound field programs, Music Enhancer, HDMI output and other options. Inputs can be set to specific sources, such as FM or Internet radio stations, stations from a streaming service, USB devices, or any song stored on a PC or NAS (network hard drive). After setting the function keys, simply press the main unit or remote control to turn on the amplifier and listen to the music you want. This function can be reset at any time.


    Easy operation with MusicCast App
