The AVENTAGE Advantage

Craftsmanship in engineering design. The AVENTAGE line of high-performance AV receivers is based on the audio design concept of providing a massive, full-bodied sound for movie sound effects and the accurate reproduction of music sources. By expertly harmonizing traditional and advanced technologies, every factor that affects sound quality, from materials and parts to construction, layout, vibration damping (unique foot) and “fine-tuning” the sound, is handled with no other thought than to achieve the best possible audio quality. As a result, every AVENTAGE model has the ability to reproduce the most subtle details of high-definition sound, so that listeners can enjoy a truly high-class sound studio experience at home.

Total Purity

Total Purity

Enjoy fine sound quality. The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity preamplification, anti-vibration technology and independent pure power supplies. All models have fully discrete power amplifiers that help minimize distortion. They also adopt pure independent power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heat sinks are designed to suppress vibration from transistors and sound pressure. Independent power supplies for the DACs are designed to further eliminate noise on certain models. Down to every detail, these AV receivers are designed with full emphasis on the highest possible sound quality.

High Quality Parts for Optimum Performance

The whole is greater than the sum. Every single part in an AV receiver affects the sound quality. For AVENTAGE models, extra time is taken to find (or develop) the exact parts needed to achieve the highest performance possible. Sound technicians go through a testing process to, in effect, “tune” the receiver’s sound.

High Quality Parts for Optimum Performance

Anti-Resonance Technology Foundation

Anti-Resonance Technology Foundation

A firm foundation. The Anti-Resonance Technology Wedge is a fifth foot in the center of the unit. 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.

Advanced Design Feet

Foot fetish. The feet of the receiver feature a newly designed, high-density structure which utilizes two different kinds of interior ribs — straight and curved — to enhance strength and damping performance. Installation stability is improved and chassis resonance is dispersed, effectively eliminating external vibration. The low-range response is enhanced, while resonance peaks in the mid- and high-range are reduced, providing dynamic sound and accurate reproduction.

Advanced Design Feet

Aluminum Front Panel

Aluminum Front Panel

Shielded from noise. All of the AVENTAGE components feature the same sleek, clean design, with an elegant aluminum front panel and silky touch volume/selector knobs. The aluminum front panel is used to effectively shield sensitive circuitry from external noise and electronic radiation generated by dimmer switches, fluorescent lighting, video monitors and so on. This ensures optimum sonic performance in the widest range of installation environments.

Discrete Amp Configuration

Designed for sound. This AV receiver was designed with a strong focus on achieving exceptionally high sound clarity. It employs a discrete amp configuration and a low jitter PLL circuit, which contribute to its excellent audio performance.

4K Ultra HD Full Support

Darker blacks, whiter whites, and more vivid colors. This AV receiver completely supports with latest HDMI® standards. Thanks to transmission of 4K video at 60 frames per second pass-through, you can fully enjoy the high definition video quality of 4K without degradation. It also adheres to the HDCP 2.2 copyright protection standard for 4K video transmission. It also supports HDR (High Dynamic Range) Video including Dolby Vision and Hybrid Log-Gamma which provides incredible contrast, smooth tone and rich, bright colors. Furthermore it supports the wider color gamut of BT.2020 pass-through. This AV receiver is also compatible with 3D, Audio Return Channel and CEC for easy operation.

*Dolby Vision and Hybrid Log-Gamma will be available via future firmware update.

It is also compatible with high-resolution audio codecs such as DSD/AIFF/FLAC/WAV/Apple® Lossless. You will enjoy the excellent sound quality of these various high-resolution audio codecs from the USB input on the front panel or from network connected devices.

Zone B Output

Second room sound. Zone B output capability allows the receiver to send 2-channel sound to a second zone, so the main zone now has 5-channel output. This means that users can enjoy stereo sound in a second room. The same source will play in both zones (cannot use two sources).

YPAO™ Sound Optimization

Sound optimized. YPAO analyzes the room acoustics and adjusts various audio parameters for optimum sound in just a few minutes. It’s like having a professional installer calibrate your system.

Rich Bass Reproduction

Feel your lows. This exclusive low-range enhancement technology delivers richer bass than you would expect from smaller sized speakers while maintaining good localization and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers, but also enhancing the bass from the subwoofer. You'll enjoy video and music with sound that has exceptional power and presence.

Subwoofer Trim

Improved sound imaging. The Subwoofer Trim Control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused soundstage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim Control takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound.

Subwoofer Trim

Compressed Music Enhancer

Hear more. When music is encoded into a digitally compressed format like MP3, the frequency response suffers. The Compressed Music Enhancer from Yamaha employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should.

Compressed Music Enhancer

Gapless Playback

Gapless Playback
