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 harmonising 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.

Advanced Design Feet Enhance Strength and Vibration Resistance

The feet of the RX-A870 feature a newly designed, high-density structure which utilises 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 focused, accurate reproduction.

YPAO-R.S.C. (Reflected Sound Control) Sound Optimisation with Multi-Point Measurement

YPAO-R.S.C. analyses room acoustics and measures various speaker characteristics, then calibrates audio parameters to achieve optimum sound at any of eight listening positions. It employs Reflected Sound Control to correct early reflections for studio-quality sound. It also provides DSP Effect Normalisation, which varies the CINEMA DSP parameters according to the reflected sounds.

YPAO Volume to Ensure Natural Sounds Even at Low Volume

Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimised to your system settings and listening environment.

HD Audio with CINEMA DSP 3D and Virtual Presence Speaker

Extra Bass Provides Rich Bass Reproduction, Even with Small Speakers

Yamaha’ s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localisation 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.

Zone Extra Bass for More Powerful Bass Sound in Another Room (Zone 2)

Use the Extra Bass feature to amplify bass tones, not just in your main room but also on system in other room (Zones 2). Even with compact or in-wall speakers which typically lack bass, you’ll hear all your sources with powerful bass sound.

Automatically adjusts bass and treble balance to match the volume on system in other rooms (Zone 2). Enjoy movies and music with a natural sound quality balance even at low volumes.

Subwoofer Trim for 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 sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilising the front stage while providing a well-balanced enhanced bass sound.
