P.SW: P.SW has extreme positive resistance-temperature characteristics. If an abnormal current flows to P.SW due to an excessive input or unusual signal, P.SW heats up and the resistance rapidly increases. With this function, the speakers are protected from excessive input or unusual signal. The resistance value increases even when using a soldering iron for repairing, so allow it to cool before using.
