Yamaha A-S801

The A-S801 features a new analog volume control located on the front panel. It utilizes electronic volume control for the highest sound quality, allowing the Loudness effect to be adjusted as desired. Separate from the normal volume control, this allows for the balance between treble and bass to be influenced. As a result, the complete tonal range is available, compensating for the natural hearing loss of high and low frequencies at low volume levels.

The ToP-ART concept (Total Purity Audio Reproduction Technology) ensures excellent sound quality in conjunction with the ART Base. This is because only when both the processing and transmission of audio signals are designed to be simple and direct can the influence of noise and distortion be minimized. The Yamaha technology for this amplifier design is called ToP-ART. It consists of a fully symmetrical structure from input to output, with the left and right channels processed using the shortest possible signal paths. This guarantees outstanding sound with unadulterated clarity. The ART (Anti-Resonance and Tough) Base housing bottom and the solid middle rail provide additional stability and dampen vibrations. These design innovations from Yamaha contribute to excellent audio playback with remarkable musicality.

With a direct connection to the CD input, the CD Direct Amplification maximizes the signal-to-noise ratio during CD playback. Additionally, when the Pure Direct mode is activated, the audio signals are routed through the shortest signal path. By bypassing the buffer amp as well as tone, loudness, and balance controls, signal loss is virtually eliminated, achieving the purest sound quality.
