なうパワーアンプ回路において電源の友イッチをOFF
したとき、パワーアンプのVcc端子に結合されたコン
デンサに充電された電荷を放電、 させることにより
、パワーアンプのミューティング端子に電流を流入させ
て、ミューティングも、動作させる事を特徴とする電源
OFF時のミューティング回路。A relay with a back contact is used to turn off the power switch in a power amplifier circuit that switches switches.
When the power amplifier's Vcc terminal is connected to the Vcc terminal of the power amplifier, a current is caused to flow into the muting terminal of the power amplifier by discharging the charge stored in the capacitor connected to the Vcc terminal of the power amplifier, thereby also operating muting. Muting circuit when OFF.
