High Strength Chassis Contributes to High Density Sound and High Purity Audio Reproduction
In order to effectively dampen the vibrations that have adverse effects on sound quality, the A-S801 chassis has a double bottom with a 1mm iron plate. In addition, the power transformer and heat sinks in the power amp section are supported by an extremely strong and stable ART (Anti-Resonance and Tough) base. A solid centre bar further enhances high rigidity support and vibration damping. These Yamaha design innovations contribute to superior S/N ratio and natural, rich sound reproduction.
High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept
ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha’s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity.
High Quality Parts for Outstanding Audio Performance
Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, onepoint grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.
CD Direct Amplification and Pure Direct Mode for Greater Sound Purity
With a straight connection to the CD input, CD Direct Amplification maximises CD source S/N ratio. Additionally, engaging the Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
Continuously Variable Loudness Control
The A-S801 also feature a new analogue loudness control on the front panel that uses electronic volume for higher sound quality, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and highfrequency sounds, providing full tonal range at any volume level, compensating for the natural loss in the human ear of high and low frequencies at soft levels.
USB DAC Function Supports 2.8MHz/5.6MHz DSD Native Resolution and PCM384kHz/32*bit Reproduction
A built-in USB DAC function allows direct connection to a PC and reproduction of today’s popular high resolution sound sources. The Yamaha-developed USB device controller IC has its own master clock that eliminates PC jitter for high resolution signal transmission. The ASIO2.3 Yamaha Steinberg USB driver achieves lower delay and higher throughput. Offering compatibility with 5.6MHz DSD native reproduction and PCM 384kHz/32-bit PCM reproduction, you can enjoy a wide range of high resolution sound sources for high quality sound. In addition, an indicator on the front panel displays easily understandable DSD and PCM playback formats and sampling frequencies.
* Windows support. Mac support is 24-bit.
