AMPLIFIER CONNECTIONS AND CONTROLS
POWER SELECTOR SWITCH
OFF
= The subwoofer amplifi er is powered down.
AUTO = Automatically powers up the subwoofer amplifer when
a signal is sent from your receiver or processor. If a signal is not
present, the subwoofer amplifi er is put into stand-by mode. The
subwoofer amplifi er will draw a negligible amount of current while
in stand-by.
ON = Turns on the subwoofer and leaves it on.

GAIN CONTROL
The GAIN control is used to adjust the output level of the sub-
woofer. This control should be set to achieve a similar acoustic
level as your loudspeakers. Proper calibration procedures should
be used to adjust the level of your subwoofer.

LED INDICATOR
GREEN
= The subwoofer is on.
RED = The subwoofer is in standby mode. The amplifi er will
enter standby mode after 13 minutes without a signal.
OFF = The subwoofer is off.

CROSSOVER CONTROL
The CROSSOVER control is used to minimze the output of the
subwoofer above the crossover’s setting. The crossover fre-
quency is variable from 40Hz to 150Hz, with an LFE mode when
turned fully clockwise.

DELAY CONTROL
The DELAY control is used to acoustically align the subwoofer
with the main speakers. The delay setting is variable from 0ms
to 16ms.

INPUTS
The subwoofer INPUTS consist of LEFT/LFE and RIGHT RCA
jacks. You only need to use the LEFT/LFE connection if you are
using a receiver or processor with an LFE or subwoofer output.
You can use a Y-connector on the subwoofer if it doesn’t power
up in AUTO mode at low levels. (
Please make sure to recalibrate
if you use a Y-connector.

ROOM SIZE CONTROL
The ROOM SIZE control is used to shape the lower end of the
subwoofers response to compensate for excessive room gain.
