and must be plugged into a standard house-
hold 110-120V AC power source in order
to operate.

The power switch has three positions: “On,”
“Off,” and “Auto” (Figure 9, page 13). 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 senses a signal com-
ing from your electronics. The amplifier and the green pilot light will turn off approxi-
mately 15 minutes after input signal ceases.
In the “On” position, the power amplifier will
operate and the green pilot light will illumi-
nate until the switch is set to “Off” position
or the AC cord is disconnected from a
power source. We recommend using the “Auto” position.
Turn it to “off” if the system will not be
used for extended periods of time, such
as during vacations.
