The PR41 passive preamp provides a volume and balance control and input selector of the highest quality.

TheĀ  passive preamp / stepped attenuator volume control has 46 steps of attenuation of 1.25 dB each. This level control is assembled using a high quality mil-spec rotary switch and presision metal film resistors. The balance control also uses a stepped attenuator with 0.6 dB steps. In one direction only the left channel gets attenuated and in the other direction only the right channel gets attenuated. The input selector switch on the passive preamp can select from 6 input channels.

The front panel of the passive preamp has the 3 controls. The rear channel has the 6 pair of input connectors and the output connectors. There is no power cord or power supply of any kind. All connectors are heavy duty brass and gold plated with teflon insulation. The cabinet is black with white lettering. Knobs are black aluminum.

The PR41 passive preamp is compatible with most any component with line level outputs, like CD player, tuner, tape recorder, etc, and with most power amplifiers, tube or solid state. Most power amplifiers have an input impedance in the range of 10KOhm to 100KOhm. The PR41 front panel is calibrated for a load impedance of 25 KOhm, but using an amplifier with a different input impedance only changes the calibration by a small amount (less than 1.5 dB) and is generally not a problem. The PR41 can also drive any of our electronic crossover networks.
