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.
Anti Resonance Technology Wedge Helps to Ensure that Vibrations Do Not Affect Sound Quality
The Anti Resonance Technology (A.R.T.) Wedge is a fifth foot in the centre 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 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.
Aluminium Front Panel Offers Visual and Aural Benefits
All of the AVENTAGE components feature the same sleek, clean design, with an elegant aluminium front panel and silky touch volume / selector knobs. The aluminium 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.

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
CINEMA DSP 3D provides a wide, high and dense sound field. HD Audio format decoding lets you enjoy HD Audio sources. Virtual Presence Speaker delivers 3-dimensional sound without actual use of presence speakers.
Virtual Presence Speaker and Virtual Surround Back Speaker
The Virtual Presence Speaker function makes full use of centre and surround speakers to create virtual presence speakers. Enjoy CINEMA DSP 3D Mode surround sound even in environments where speaker installation is limited. In addition, this model also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural sound from behind you.
Virtual CINEMA FRONT Provides Virtual 7-channel Surround Sound with High Quality and Resolution
Even when it is impossible to install surround speakers behind the listening position, Virtual CINEMA DSP reproduces virtual 7-channel surround sound filled with realism, from only two front speakers. The Virtual CINEMA FRONT feature lets you place two surround speakers and a centre speaker at the front to enjoy virtual 7-channel surround sound with even higher quality and resolution, as well as superior rear virtual sound localisation. Adding two additional front presence speakers provides a three-dimensional sound field that gives you a feeling of its height and depth and of the vertical movement of the sound. You get more flexibility to arrange your speakers inside the room, along with easy enjoyment of high quality surround sound.
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.
Zone Volume Equalizer for Optimum Sound Balance in Another Room (Zone 2)
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.
ECO mode Lowers Power Consumption by 20%*
Yamaha’s new ECO mode reduces power consumption by about 20%. It can be set from the top of the GUI menu.
*Compared to power consumption when ECO mode is off (Yamaha measurement).
Selectable Auto Power Standby
Auto Power Standby lets you save energy by selecting to turn off the power after 20 minutes, 2, 4, 8 or 12 hours.
With an advanced energy saving design, this AV receiver achieves a low power consumption of not more than two watts when in Network Standby mode.
