Claim:
1. An acoustic processing device comprising: a controller; a signal input/output unit that receives and outputs a signal from/to a first external equipment; a sound signal processing unit that performs predetermined processing on a sound signal and outputs the sound signal; a sound output terminal from which a sound is output to a second external equipment; a main power supply; and an auxiliary power supply, wherein the controller performs a standby through mode which supplies power from the auxiliary power supply to the signal input/output unit, without causing the main power supply to supply power, in order to output an input signal to the first external equipment or the second external equipment, the controller supplies power from the auxiliary power supply to the sound signal processing unit as well in the standby through mode, and the sound signal processing unit in the standby through mode extracts the sound signal from the signal which is input to the signal input/output unit, extracts a high-frequency sound component and a low-frequency sound component from the sound signal, outputs the high-frequency sound component to the signal input/output unit, and outputs the low-frequency sound component from the sound output terminal.
