  • Notes
  • A 2 x 100 watt integrated stereo amplifier which operates in Class A mode at normal listening levels and switches automatically to Class AB mode to handle high peaks and at high listening levels. It also has AVSS (Automatic Voltage Shift Supply), a circuit which enables the amplifier to respond instantaneously to the power demands of the wide dynamic range typical of digital recordings. Inputs for Phono (MM or MC), CD, Tuner, TV/Aux1, Video/Aux2, input/outputs for 2 Tape recorders and terminals for two pairs of loudspeakers. On the front, push buttons for Power, Speakers (1, 2), Tone Defeat, Tape Copy, Tape Monitor, MM/MC Phono, Loudness, Mono, CD/Phono Direct, rotary controls for Left and Right Treble, Left and Right Bass, Volume, Balance, rotary switches for Selector (CD, Phono, Tuner, TV/Aux1, Video/Aux2), and Rec Out (CD, Phono, Tuner, Source, TV/Aux1, Video/Aux2). Jack for headphones.
