INTRODUCTION

Congratulations on your purchase. The D-350 solid state dual channel power
amplifier was conceived and designed for audio perfectionists. Analog Module
front end circuitry coupled to a unique linear output stage provides stable
"high definition" performance.

The D-350 output stages utilize a total of 64 power devices coupled to a special
heat sink design. It will drive capacitive or inductive loads and withstand
accidental shorts without the aid of protective circuitry. It is also self-

biasing - no internal biasing or balance adjustments are used or needed. Sonic
performance will not change with time or temperature.
