  • Notes

  • A hi-fi stereo pre-amplifier similar to the earlier NAD 1020A Stereo Preamplifier.

    With RCA input sockets for Phono (MM or MC), Tuner and Aux, input/output RCA sockets and DIN socket for Tape, a Phono MM/MC selector switch and a phono Capacitance Selector switch (100pF, 200pF, 320pF). Output sockets for Pre-out and High-Level Pre-Out. Some models have three AC outlets and some have a voltage selector.

    Rotary controls for Bass, Treble, Balance and Volume, push buttons for Power, input selection (Aux, Tuner, Phono, Tape), Mono and Loudness. Power On pilot light and jack for headphones. Rack mount handles are an optional extra.
