Abstract

PURPOSE:To inform an accurate position of balance center to a user, by comparing the voltage to be applied to a balance control circuit of an electronic volume with the reference voltage and then giving an alarm when a coincidence is obtained through the above-mentioned comparison of voltage. CONSTITUTION:An electronic volume 1 consists of a balance control circuit 5 to which the DC voltage is applied from variable resistors 2, 3 and 4 each, a tone control circuit 6 and a volume control circuit 7. A voltage comparator 11 compares the DC voltage Vb applied to the circuit 5 with the reference voltage Vref supplied from a reference voltage generating circuit 10. Then the resistor 2 is first controlled, and a sound generator 13 produces a sound for warning when the voltage Vb coincides with the voltage Vref. In such way, a user can know accurately that the volume 1 is at the position of balance center.
