  • A Quadraphonic (or Stereo) AM/FM Hi-Fi Receiver with a tuner covering MW and FM and an amplifier with power output of 4 x 20 watt RMS (or 2 x 45 watt RMS ) into 8 ohms. Rotary Controls for Mode, Dual Front-Back Bass and Treble, four individual Balance controls, Master Volume, Function Selector and Tuning. Push Buttons for Power, Front or Main Speaker system,  Back or Remote Speaker system, High Filter, Loudness, Tape Monitor and FM Muting. With illuminated Tuning Meter, Function indicators, Mode indicators and Stereo Indicator. Adjustable bar aerial on the back, two AC outlets. DIN or RCA phono sockets for Phono MM, Aux input and Tape input/output, terminals for 2 pairs of loudspeakers and 2 jacks for Headphones.
