below the top plate or the back plate of this device. There are no user serviceable parts
inside. Please refer all servicing to licensed service technicians. CAUTION! The inter-
national symbol of a lightning bolt inside a triangle is intended to alert the user to uninsu-
lated “dangerous voltage” within the device’s enclosure. The international symbol of an
exclamation point inside a triangle is intended to alert the user to the presence of important
operating, maintenance and servicing information in the manual accompanying the device.
CAUTION! To prevent electrical shock, match wide blade of plug to wide slot, fully insert.

Please follow the guidelines below to ensure best performance:
AMPLIFIED VERSIONS
POWER SWITCH
• OFF/TRIG – Manually
turns the amplifier off. Also
used to turn amplifier on/
off through the 12v trigger
• AUTO – Senses an
input signal to turn on the
amplifier. Amplifier will turn
off automatically approx-
imately 20 minutes after
the input signal is no longer
sensed
• ON – Manually turns the
amplifier on continuously
STANDBY – Indicates AUTO
sense is on
ENABLE – Indicates the
amplifier is on. Power
Switch in ON or in AUTO
with input signal sensed
GAIN – Volume
control
LF ADJUST – +/-
12dB Peaking filter at
25Hz w/ Q = 2 Adjust to
compensate for listening
room acoustics and speaker
placement
Crossover – 60-500Hz Low
Pass Filter
Delay – 0 -20ms time delay.
Select to adjust for listening
room placement of the
subwoofer relative to main
speakers
RCA Inputs – left and right
inputs
12v Trigger Inputs/Out-
puts – Accepts 12V trigger
input to control amplifier
power
XLR Input and Looping
Output –Balanced input
with looping output to con-
nect multiple subwoofers.
When XLR input is detected,
and no RCA is connected,
RCA inputs are muted
This is a very high output
amplifier. Proceed with
caution when applying the
gain to ensure you are not
maxing out the signal
NON-AMPLIFIED VERSIONS
Connect the positive speaker wire and negative speaker wire from the
amplifier directly to the push terminals on the back of the subwoofer
Wire the positive speaker wire to the positive terminal and negative
speaker wire to the negative terminal located on the back of the
subwoofer
Strictly adhere to the subwoofers power handling capabilities
ROOM PLACEMENT
One of these placements may be best for your room/seating position.
This can only be done empirically and takes quite a bit of time, trial
and error. Listening, over a period of months, generally yields best sub
position.
Option 1 - Midway between front left and right main speakers. This
position is generally preferred for its transitional coherence but is not
“carved in stone”
Option 2 – Midway along sidewall relative to the listening position
Option 3 – Behind the listening position near a back-wall corner. Note:
Placing the sub in a corner will increase output between 3 - 6 db. Iron-
ically this corner option is generally least desirable due to loss of bass
detail
ADDITIONAL INFORMATION
Wall Outlet: In the US 110V – 20-amp service preferred as 12-gauge
wire, used for 20-amp service, provides a better draw supply to the
amplifier. There is a slight improvement in tightness and bass speed
going from 16 amp to 20 amp
Rubber feet are included to provide isolation between bottom of sub
and floor. This isolation is necessary for clean bass
Subwoofer response is complex and room interactive. In addition, there
is a break in period of about 2 weeks to attain best performance. We
suggest moving the sub to a variety of different positions within the
listening area
