Integrated Amplifier Yamaha A-S801

Yamaha A-S801

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.
