Power Connection

plugging the subwoofer into the switched outlet of an amplifier,
preamplifier or receiver. The power demands of the subwoofer amplifier may exceed the power rating
of the switched outlet and may damage the equipment.
The 4.5 PBM is totally automatic in its operation. The automatic on/off circuitry will only activate the
subwoofer in the presence of an audio signal from your audio/video system. After 7-10 minutes with
no signal detected from the rest of the system, the amplifier will shut itself off and go into standby
mode. When an audio signal is present, the power LED located under the front grille will glow green.

by plugging the 4.5 PBM into a heavy-duty switched power outlet strip if you desire. In this mode, the
subwoofer will be powered when the power switch is turned on and it will still operate in automatic
standby/on mode when the power strip is active.
