Description

The SA-9900 is a top of the line stereo integrated amplifier with state-of-the-art technology and advanced features.

Differential amplifier circuits are employed in the equaliser, tone control and power amplifier sections.

Each amplifier section is supplied by a balanced power supply system that assures excellent DC balance and stability, while nearly eliminating switching noise during control operation.
