  • A 2 x 140 watt stereo integrated amplifier with a Mosfet power stage, 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. Inputs for Phono (MM/MC), CD, Tuner, Aux1, Aux2, input/outputs for 3 Tape recorders (DAT/Tape1, DAT/Tape2, Hi-Fi VCR), and terminals for two pairs of loudspeakers (System 1, 2). Sockets for Pre Out and Main In. On the front, push buttons for Power, Speakers (1, 2), Tone Defeat, Tape Monitor (Source, DAT/Tape1,DAT/Tape2, Hi-Fi VCR), Muting, Subsonic filter, Mono and CD/Phono Direct,  rotary controls for Treble Left, Treble Right, Bass Left, Bass Right,Volume and Balance, rotary switches for Selector (CD, Phono,Tuner, Aux1, Aux2), Phono (MM, MC High, MC Low) and Tape Copy (Hi-Fi VCR > Tape 1/2, Source, Tape 1 > Tape 2/Hi-Fi VCR, Tape 2 > Tape 1/Hi-Fi VCR). Jack for headphones.
