Patent

CA 2150226

A current drain reducer for an electronic system such as an electronic amplifier operated through controlling selected circuit branches (circuitry of amplifiers 11', 12') said circuit branches each has a control conductivity device located therein which has a control therefore connected to a shutdown signal generator (15'). The potentiometer (16) can have its end terminals in one said circuit branch which may be in a first electronic amplifier circuit (11') and its wiper connected to another said circuit branch which may be in a second electronic amplifier (12'). A sensing circuit (40) for sensing the position of the wiper provides an output signal to the shutdown signal generator (15') in response to sensing a selected position of a potentiometer (16) used therein.
