LINE IN
L & R
LFE & Unbalanced RCA inputs for left and right channel. Choose the left one when using LFE signal. The
left and right inputs are a sum, providing bass for both channels.
XLR BALANCED
IN
This is a balanced version of the LFE signal
XLR BALANCED
Pass Through
This works as a pass through for the XLR balanced signal, this makes it possible to connect several subs
with one signal from the source.
FREQ
This control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to 170 Hz.
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 100-150 Hz). With larger speakers that have greater low frequency output, you might
start with this control set lower (such as 60-100 Hz). (4th order LPF, 24dB/oct.)
PHASE
This control allows you to alter the phase of the subwoofer’s output signal , 0 ° - 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 tune between 0 ° and 180 ° and listen for a change in mid-bass
output. The correct position will have a higher amount of apparent mid-bass output.
GAIN
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 a 9 o’clock position.
For music systems, start with the volume control at a low setting and proceed slowly from there until the
levels match. The 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.
Low Pass
The low pass filter cuts away high frequencies at a certain point and over, the frequency point is set by the
crossover variable. We recommend that when using LFE signal to turn the low pass filter off, as most receivers
are handling filters internally.
EQ
This switch allows you to choose between the three different EQ settings.
REF, EQ1 & EQ 2 are explained in the “EQ” section, found on page 12.
PARAMETRIC EQ
On / Off
At the “
On
” position the PEQ filter is active.
At the “ Off ” position the PEQ filter is bypassed and does not influence the signal in any way.
More info is found in the "PEQ" section, found at page 15.
PARAMETRIC EQ
Frequency
The frequency potentiometer allows the user to fine trim the frequency area that need to be tuned.
PARAMETRIC EQ
Gain
The gain potentiometer allows the user to adjust the boost or decrease of the targeted frequency.
