P.SW
P.SW has extreme positive resistance-temperature characteristics. (Less than 0.3W at
the normal temperature). 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.
