The Reference Standard in AV Receivers
AVENTAGE AV receivers are the reference standard to which all others are compared. Passionate engineering and meticulous attention to detail produce the Yamaha hallmark of True Sound. You can feel the quality in the design and fabrication ? from every electrical path, component and piece of material. Each element was scrutinized with intense detail to produce the finest, first-class performance. The AVENTAGE AV receiver is a work of visual and acoustic art.

BREATHTAKING SOUND

Dolby Atmos and Dolby Atmos Height Virtualization
Feel every dimension in Dolby Atmos. Enjoy a 5.1 surround speaker system and two additional overhead speakers or two Dolby Atmos elevation speakers, delivering dramatic overhead effects for truly enveloping audio.

For those without in-ceiling or upward firing speakers in their system, Dolby Atmos Height Virtualization technology can simulate the Atmos experience. Configure up to five speakers to replicate the effect of two in-ceiling speakers, or utilize all seven channels to simulate the powerful effect of four overhead speakers.

DTS:X
DTS:X immersive audio formatting places sound where it would naturally occur in space, creating life-like, multi-dimensional audio. The included spatial remapping engine of DTS Neural:X offers improved immersion and heightened realism in all your favorite movies.

CINEMA DSP 3D for Movie, Music and Game
This unique Yamaha proprietary sound field creation technology, was created by combining measured sound field data with digital signal processing. Yamaha collected sound field data from famous concert halls and music clubs around the world, utilizing its wealth of experience in the fields of concert hall design, public address and mixing. By digitizing this vast trove of information and incorporating it into dedicated LSI devices, it effectively reproduces the spaces of concert halls and music clubs in your home. Immerse yourself in the astounding realism of your movies, and enter a world of profound theater sound.

Compressed Music Enhancer
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 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.

TRUE SOUND
Make every night movie night. In fact, feel like you’ve entered the story. The Yamaha approach to tonal balance delivers incredibly detailed and accurate timbre in each voicing. Dynamism is found in the emotive contrast between the stillness and motion in the movie. The urgency and suspense between action scenes is palpable through the sound field that is created.

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.

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.

4K120AB, 8K60B and 4K60
This receiver supports end-to-end 8K/4K resolutions and higher refresh rate solutions with a single upgraded cable for seamless integration within the HDMI eco-system. 8K delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels; and combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action. 4K120 enables ultra-fast motion UHD images to be crisp and razor sharp; allowing sports, action movies, high-performance gaming and VR to benefit significantly. It also supports Dolby Vision? and Hybrid Log-Gamma.

Enhanced Media and Gaming (ALLM and VRR)
Enhanced media and gaming features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include: Auto Low Latency Mode (ALLM), which enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity; Variable Refresh Rate (VRR), which reduces or eliminates lag, stutter and frame tearing for more fluid and detailed gameplay.

DESIGNED FOR YOUR SPACE

YPAO automatic room calibration with R.S.C. and Multipoint
YPAO (Yamaha Parametric room Acoustic Optimizer) analyzes your room acoustics, measures speaker characteristics and adjusts unwanted reflected sounds to optimize every channel of your home theater. R.S.C. (Reflected Sound Control) analyzes room acoustics and measures various speaker characteristics, then calibrates audio parameters to achieve optimum sound at any of eight listening positions.

Simply by placing the supplied microphone at your listening position and switching YPAO on, the system is automatically calibrated ensuring your home theater room has the best sound.

Compelling Design
Yamaha AV receivers are crafted with meticulous design and craftsmanship to produce a work of visual and acoustic art.

The immaculate chassis construction further solidifies the alignment of stability in performance. It offers a beautiful form that deepens the AVENTAGE uniqueness and continues to further enhance key acoustic authority.

Inspired by tradition and incorporating fresh new design principles, the new look of AVENTAGE exhibits engineering at its most innovative and awe-inspiring best.
