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.

PANEL FACILITIES SUBWOOFER REAR SECTION 1 POWER indicator Illuminates RED when the power is being supplied. 2 Volume LEVEL Volume of subwoofer is adjusted with this knob. Turn this knob clockwise to raise the level. ¶ Starting with “MIN“, turn this knob and raise the volume slowly. If the unit is turned on with the volume set too high, it could cause hearing and/or speaker damage. Do not turn the volume up excessively high. The low frequency sound is apt to be raised too high since it is less disturbing and harder to detect than high frequencies. Caution must be taken here since the amplifier and speaker will be clipped when the output of the amplifier or receiver is inc- reased with the subwoofer level set to "MAX". 3 LINE LEVEL IN Connect SUBWOOFER OUTPUT terminal of the receiver to this terminal with the supplied RCA cable. If the output of the receiver connected to this unit is high or if the output has a low range boosted by the Bass control, Bass boost, or other means, there may be some sound distortion even if the level of the unit is lowered. In this case, lower the output level (Volume, Bass control, Bass boost) on the receiver side.
