AC POWER
The PSW1200 has a built-in power
amplifier and must be plugged into a
standard household 110-120V AC power
source in order to operate.
The power switch has three positions:
“On,” “Off” and “Auto”
(Fig. 16). In the
“Auto” position, the amplifier will auto-
matically turn on, and the green pilot
light on the front of the subwoofer will
illuminate, as soon as the speaker sens-
es a signal coming from your electron-
ics. The amplifier and the green pilot
light will turn off approximately 15 min-
utes after input signal ceases. In the
“On” position, the power amplifier will
operate and the green pilot light will
illuminate until the switch is set to “Off”
position or the AC cord is disconnected
from a power source.
SUBWOOFER ADJUSTMENTS
SUBWOOFER LEVEL
CONTROL–Subwoofer level is adjustable
via the knob on the front of the sub-
woofer under the logo pod (Fig. 17).

age amount of bass
