Abstract

PURPOSE: To make the checking of the balance between channels easy by providing respectively corresponding plural operating knobs and radial light emitting body arrays to plural channels and driving the light emitting bodies according to the operations of the knobs.
CONSTITUTION: When the operating knobs are depressed, movable contacts 3aW3d close circuit foils 11aW11d to drive electronic volume controls. The electronic volume of the respective channels are mutually interlocked so that when the volume on the one side is increased the other becomes correspondingly smaller. The outputs of the volume are detected in driving circuits 12aW12d respectvely which in turn drive light emitting bodies 7aW7d, 8aW8d, 9aW9d, 10aW10d according to respective levels. By viewing the light emission patterns of these four light emitting body arrays, the sound volume balances of the four channels may be checked.
