A hi-fi stereo integrated amplifier housed in a black case (or silver case, Germany only) with continuous power output of 2 x 35 watts into 8 ohms (2 x 40 watts into 8 ohms DIN). With rotary controls for Volume, Balance, Bass and Treble, rotary Input Selector (DAT/Tape1, CD, Phono, Tuner), push button switches for Speakers (A,B), Direct, Loudness and Adapt/Tape2 and a jack for headphones. RCA phono sockets for input Phono, Tuner, CD, for input/output DAT/Tape1 and Adapt/Tape2 and terminals for 2 pairs of loudspeakers (A, B). The General Export model (SD) also has 3 AC outlets.
The later Pioneer A-227 Integrated Stereo Amplifier is the same apart from appearance.
