  • Notes

  • A Stereo pre-amplifier, the same as the pre-amplifier section in the integrated NAD 3020 Series 20 Stereo Amplifier.

    With RCA input sockets for Phono (MM), Tuner and Aux, input/output RCA sockets and DIN socket for Tape and a Phono Input Capacitance Selector switch (100pF, 220pF, 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), Audio Muting and Loudness. Power On pilot light and jack for headphones. Rack mount handles are an optional extra.
