ABSTRACT:
A balance control circuit for controlling the difference in volume between right and left audio stereo signals. DC output voltages of an amplifier provided in a preceding stage to the balance volume control circuit are utilized as bias voltages for amplifiers provided in the rear stage of the balance control circuit, and the sliding contacts of variable resistors are grounded through a single capacitor, with the result that the manufacturing cost of the circuit is reduced.
