Abstract

PURPOSE: To prevent the voice of a left output terminal and a right output terminal from being substituted affected by a main/sub switching control signal when a switching circuit is in a main/sub voice mode by adding a fixed circuit for the main/sub switching control signal.
CONSTITUTION: When a mode control signal A is at 'L', the main/sub voice mode is introduced by closing switches 6 and 7 at a switching circuit 3. At such a time, the input terminal of a main/sub voice control signal B is fixed forcibly at 'L' by a diode 12 and by closing switches 8 and 10, a main voice is always outputted from the right output terminal and a sub-voice is outputted from the left output terminal. At the next, when the signal A is at 'H', the circuit 3 is realized to be a main voice mode or a sub-voice one by closing the switches 6 or 7. At such a time, if the signal B is at 'L', the main voice is outputted from both output terminals of right and left by closing the switches 6, 8 and 9 and if the signal B is at 'H', the sub-voice is outputted from both output terminals of right and left by closing the switches 10 and 11.
