ンバイ回路。 a power-off mode in which no power is supplied to the circuit;
In a playback device that can be selectively set to a power-on mode in which power is supplied and an audio signal is output to a speaker, and a power standby mode in which an audio signal is not output to the speaker while power is supplied, speaker protection means for detecting abnormal operation of the power amplifier and disconnecting the speaker circuit from the power amplifier; control signal generation means for generating a control signal when the power standby mode is selected; and protection for the speaker by generating the control signal. A power standby circuit characterized in that it is provided with a muting actuation means for actuating the means.
