4 Line level input These RCA jacks accept a line-level, full-range signal
from the pre-amplifier or LFE output of a receiver or
preamplifier.
This full-range signal is processed and amplified to
power the subwoofer.
5 Polarity switch This two-position switch allows the best match of
acoustic output between the subwoofer and the
satellite speakers in the crossover frequency region
between them.
• The 0° position maintains phase from input to
output.
• The 180° position changes the polarity by 180°.
Try both settings and pick the one that sounds best.
6 Status LED This shows the status of the subwoofer.
• Red indicates that the amplifier is plugged in and
the power switch is either off or in standby mode
with no input signal present.
• Green indicates that the amplifier is operating
with a signal present at the input from the
pre-amplifier, receiver, or power amplifier.
7 Subwoofer
crossover
(frequency) This rotary control sets the upper frequency at which

satellite speakers.
Recommended setting: 150 Hz.
8 Volume control
(gain) This rotary control adjusts the level of the subwoofer
and is used to balance its volume with that of the
satellite speakers.
9 Main power switch This switch controls the overall power status of the
subwoofer. It must be in the ON position for the
subwoofer to operate.
