Yamaha A-S501

• Output power of 2x 85 W
• Selected components for best sound quality
• Without loss of sound details thanks to «Pure Direct»
• Stepless "Loudness" control
• 4x speaker connection, 1x subwoofer output

The Yamaha A-S501 is a full-range amplifier with an output power of 2x 85 watts, which can operate up to two pairs of stereo speakers at the same time. In addition, an active subwoofer can be connected to the subwoofer connector for improved bass reproduction.

The quality of the individual parts and their interplay are decisive for the sound of each component. That's why Yamaha uses only high-quality components that are carefully selected and tested. The A-S501 guarantees excellent signal reproduction even under demanding conditions - the power transformer and the blocking capacitors are specially designed, the loudspeaker relays have a direct signal path, one-point grounding as well as extruded aluminum heat exchangers.

The "Pure Direct" circuit allows bridging circuits, such as sound control, to provide the shortest signal path from the input to the amplifier and to reproduce the signal as unchanged as possible.

The A-S501 has a new analogue loudness control, which is attached to the front. It uses an electronic volume control for the highest sound quality so that the loudness effect can be adjusted as desired. Separated from the normal volume control, the balance between treble and bass can be influenced. This provides the complete tonal bandwidth, and the natural hearing loss of high and low frequencies at low volume is compensated.
