回路切換時のミューティング回路。It has a common contact and a plurality of fixed contacts, the common contact is connected to a power source, and each of the fixed melting points is connected to a unit device circuit, so that the common contact and the plurality of fixed contacts are short-circuited during a switching operation. A shorting type changeover switch is provided, and a diode is connected in the opposite direction to each of the fixed contacts, and when the changeover switch is operated, a "1" level is output, and when the changeover is set to any of the fixed contacts. An AND circuit that outputs a "0" level and a signal line and ground in each of the unit device circuits connected to the AND circuit that outputs the "1" level of the AND circuit.
1. A muting circuit for switching a power supply circuit, which is equipped with a switching element for muting that is turned ON by a level output signal.
