Integrated Amplifier PM-50

A 2 x 70 watt stereo integrated amplifier with LDPS (Linear Drive Power Supply), a low impedance wide bandwidth power supply which ensures tonal and dynamic fidelity into difficult loudspeaker loads. Input sockets for Phono (MM/ MC), CD, Tuner, Aux2, and Aux1, input/output sockets for 2 Tape recorders and terminals for two pairs of loudspeakers (System 1, System 2). On the front, push buttons for Power, Speakers (1, 2), Source Direct, Tape 1, Tape 2 and Mono, rotary controls for Bass, Treble, Volume and Balance, and a rotary Input Selector switch (Phono MC, Phono MM, CD, Tuner, Aux1, Aux2). Jack for headphones.
