  • Bemerkung

  • A 2 x 100 watt stereo integrated 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 and with 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, CD, Tuner, TV/Aux1, Video/Tape2, input/outputs for 2 Tape recorders, terminals for two pairs of loudspeakers and 3 AC outlets. On the front, push buttons for Power, Speakers (1, 2), Tone Defeat, Tape Copy (1 > 2), Tape Monitor (1, 2), MM/MC Phono, Loudness, Mono and CD/Phono Direct, rotary controls for Treble Left, Treble Right, Bass Left, Bass Right, Volume and Balance, and rotary switches for Selector (CD, Phono, Tuner, TV/Aux1, Video/Aux2) and Rec Out (CD, Phono, Tuner, TV/Aux1, Video/Aux 2). Jack for headphones.
