ABSTRACT:
A variable impedance device which is connected between the preamplifier of a microphone or electric instrument and a public address system for controlling the signal volume of a musical performance. The variable resistor is controlled by a foot pedal operated by the performer so that his hands are free for an uninterrupted performance. The impedance includes a first section that can be preset manually to provide maximum desired signal volume with the footpedal in one direction (toe depressed on the pedal) and a second section that can be preset to provide minimum desired signal volume (heel depressed on the pedal).
