1. Power indicator

It indicates the built-in power amplifier power on/off condition. It is lit when turning on the [POWER] switch. It is unlit when turning off the [POWER] switch.

2. [INPUT] terminals

A signal source output from PC/portable music player or a line level signal output from an amplifier is connected to the [INPUT] terminals . If the signal source is connected to the PHONE jack, the signal source fed to the RCA terminal is cut.

3. [THRU OUT] terminal

A signal fed to the [INPUT] terminal is output from the [THRU OUT] terminal regardless of the power switch on/off condition. If the signal is taken out from the PHONE terminal, the signal source output from the RCA terminal is cut.

4. [PHASE 0º, 180º ] switch

This switch changes the sub woofer phase between 0º and 180º.

<CAUTION>

When this unit is used for a long time, the heat sink

heats up. Do not touch it with a bare hand. You

might suffer a burn. Please place the unit in order

Connecting PM-SUBn to PM0.4n (x 2 units)

Connect a stereo signal source from PC/portable music player to the PM-SUBn INPUT terminals (L, R). Next, connect the PM-SUBn THRU terminal (L, R) to a pair of PM0.4n INPUT terminals. The connection is the same when PM0.5n is used as a main speaker system.
