Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To save the number of terminal pins and to reduce cost with a simple housing by eliminating an external capacitor and the terminal pin requested for it. SOLUTION: When a selection key is operated, a selection switch 11 is driven and the gain of an operational amplifier 15 is controlled by an electronic switch 23 and a voltage dividing unit 19. Since a stereo recorder 17 is not connected to the selection switch 11, an AND circuit 43 to which a signal *FM is conducted when a MUTE signal is inputted. A control switch SW 3 is installed and the positive input terminal of the operational amplifier 15 is grounded and is interrupted from an audio signal path. The operational amplifier 15 maintains an operation with DC voltage. A digital control signal 37 gives a counting start signal to a counter 65 as soon as the MUTE signal is released, and analog voltage is increased or decreased. When a comparator 57 monitors the DC voltage of addition output 55 and detects voltage to be zero, a stop signal is given to the counter 65 and the compensation of offset voltage in the operational amplifier 15 is continued by a D/A converter 53.
