AVENTAGE AV Receivers: Designed to Deliver the Highest Levels of Audio Performance
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 Concept for the Finest 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 a fully discrete power amplifier that helps to minimize distortion. They also adopt independent pure power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heatsinks 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

Anti-Resonance Technology Wedge Helps to Ensure that Vibrations Do Not Affect Sound Quality
The Anti-Resonance Technology Wedge (A.R.T. Wedge) is a fifth foot in the center of the unit. It dampens vibrations from the power transformer, power transistors and heatsinks, as well as vibrations that might be caused by the sound from the speakers.

Aluminum Front Panel Offers Visual and Aural Benefits
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.
