  • Annotazioni

  • A stereo hi-fi integrated amplifier with output power of 60 watts RMS (70 watts DIN) per channel into 8 ohms or 80 watts RMS (100 watts DIN) per channel into 4 ohms, housed in a black or silver metal case (referred to as the A-443-S model in the Service Manual only). Push button switches for Speakers A and B, Subsonic, Loudness, Direct, Muting and Phono Selector (MM/MC), rotary Bass and Treble tone controls, rotary switches for Rec Selector (Tape 2→1, Tape 1→2, Source, Off, CD, Tuner) and Input Selector (Tape2, DAT/Tape1, CD, Phono, Tuner and Line) and a jack for Phones. On the back, RCA phono input sockets for Phono, Line, Tuner and CD, input/output sockets for DAT/Tape1 and Tape2, input/output sockets for connection to an equalizer (after removal of two shorting bars), terminals for two pairs of Loudspeakers (A, B) and on the Canadian and general export models, 3 AC outlets.
