UNIVERSAL PREAMPLIFIER

This Universal preamplifier is suitable, for use with a wide range of power amplifiers since it will deliver a nominal output voltage of 440 mV/1kΩ.

The preamplifier employs highlevels of ac and dc feedback ensuring a very low distortion level (<0.15%) and variations from the nominal performance characteristics given here due to component tolerances are negligible.

There are five different inputs: crystal pick-up, magnetic pick-up, radio tuner, tape recorder and magnetic microphone. In the magnetic pick-up position the amplitude/frequency characteristic is in accordance with the R.I.A.A. standard. In addition the preamplifier provides an output signal of 0.35 mV/1 kW for tape recording.
