3.1 NETWORK ASSY
A
[1] Network Assy (SWN6040)
P.SW:
P.SW has extreme positive resistance-temperature characteristics.
If an abnormal current flows to P.SW due to an excessive input or
B
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.
