Abstract
PURPOSE: To easily release output control by providing a control channel detection circuit, detecting an output control signal for each channel and using the output control signal so as to control the output of the voice signal of each channel thereby using one external output control signal.
CONSTITUTION: A control channel detection circuit 5 detects a control signal of each channel. For example, a control signal detection circuit 6 detects a control signal to a voice input signal 1 and similarly, detection circuits 7-9 detect a control signal to voice input signals 2-4. When any control signal is able to be detected, a high level is outputted as the output control signals 1-4 and a low level signal is outputted when not detected. When the control signal is at a high level for each channel in the output control circuits 1-4 and no signal is outputted at a low level. That is, each control signal is detected for each channel and each voice signal is outputted only when the control signal is able to be detected.
