Abstract:
A surge protection circuit acquires a surge signal from a left channel (LC) signal line and a right channel (RC) signal line. After the surge signal being transmitted on the LC signal line and the RC signal line is removed, an audio signal outputted from a signal input device is transmitted to an audio output device via the LC signal line and the RC signal line.
