Connections & controls
XLR Balanced Input (1) Professional style balanced XLR input. Note, all inputs are summed together (L/R RCA & XLR).
XLR Direct Pass-Thru
(XLR Output) (2)
Professional style balanced XLR pass through (unbuffered)
RCA Input (3) Consumer style unbalanced RCA inputs. Note, all inputs are summed together (L/R RCA & XLR).
Low Pass Filter Switch -
LOW-PASS FILTER ON or BYPASS
(OFF) (7) (set to grey dot if
using a surround processor)
This switch removes the subwoofer’s built in electronic crossover circuitry from the signal path. When using
a surround sound receiver/processor, set this switch to “BYPASS (OFF)” to disengage the subwoofer’s built in
crossover. For installations which do not have a separate electronic crossover, we recommend you set the
switch to “ON” as the internal crossover will improve performance if you do not have an external crossover.
Variable Low-pass - 40 to
160Hz (4)
This control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 160Hz.
The subwoofer’s output level will be reduced above the frequency this control is set to. You should set
the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main
speakers in your system. If your main speakers are smaller units with limited low frequency output,
start with a higher frequency (such as 100-150Hz). With larger speakers that have greater low frequency
output, you might start with this control set lower (such as 80-100Hz).
Variable Phase - 0° to
180° (5) (set to reference
settings if using a surround
processor)
This control allows you to alter the phase of the subwoofer’s output signal up to 180° to correct for a
possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier.
To adjust, listen to the system with music playing and rotate the knob from 0 to 180 and listen for a change
in mid-bass output. The correct position will have a greater amount of apparent mid-bass output.
Bass Level (6) (set to grey
reference setting if using a
surround processor)
This control allows you to adjust the output level of the subwoofer to match the main speakers in your
system. For most home theater receivers & surround sound processors, set the volume control to the
“REF LEVEL” position indicated by the green dot. The “REF LEVEL” position is calibrated to work with most
surround sound systems once the receiver/processor levels are properly adjusted. For music systems,
start with the volume control at a low setting (e.g., -6dB) and proceed slowly from there until levels match.
Use of test tones (from a receiver/processor’s built in calibration function or test disc) and SPL meter are
suggested for proper level matching of all speakers.
EQ Setting Switch – ANECHOIC
ROOM EQ or ROOM GAIN EQ (8)
This switch allows you to choose between the two different EQ settings. ANECHOIC ROOM EQ gives a
flat frequency response all the way down if there is no room influence. When placed in a room this EQ
setting can get boomy because of the gain of the room. The ROOM GAIN EQ is to counteract that with a
smoother roll off and does not play as deep in frequency to get a flat frequency response in the room
with the added room gain.
Auto Turn on Switch - AUTO
ON/OFF or ALWAYS ON (9)
With this function in the “AUTO ON/OFF” position, your subwoofer can be safely left with the main power
switch on continuously (Note - works only with RCA inputs). The subwoofer will turn itself on automatically
when an audio signal is present at either RCA input connection. If no signal is present for approximately 12
minutes, the unit will switch to standby mode (indicated by red power LED color). While in standby mode,
your subwoofer will draw very minimal power. This function can be disabled by setting this switch to
the “ALWAYS ON” position.
Note, the auto on/off function operates only in conjunction with the RCA inputs. If using
XLR inputs, you must set this switch to “ALWAYS ON”.
