Abstract
PURPOSE:To enable special adjusting works such as monitoring of each sound volume adjusting state and fadar locking, by controlling the position of an operating member for sound volume adjustment and the amount of sound volume adjustment independently, through the control of an attenuator with a level control signal. CONSTITUTION:A position detector 51 detects an operating position of an operator 56 which is driven with a motor 55 or operated manually and supplies the position detecting data signal to a signal selection circuit 53 and a controller 52. Further, the controller 52 provides storage circuits and a data input/output control circuit and produces a control data signal and a driving control signal based on the position data, and supplies this control data signal to the signal selection circuit 53 and supplies the driving control signal to the motor 55. Moreover, the motor 55 moves the position of the operator 56 according to the driving control signal to control the sound volume. Further, a control signal 50A is supplied to a voltage control type attenuator 50, and a signal applied to an input terminal is suitably attenuated and picked up at a terminal Out.
