3.)High-Level Outputs

Speaker level passthrough outputs using spring clip type jacks to permit connection with bare wire. Used to 
connect from the subwoofer amp to pass signal from the full range amp on the main L/R speakers. Signal is 
only present on this output if the high level input is also used. Th

  e signal to the L/R speakers is not fi ltered. Th

 e 

impedance “seen” by the fullrange source amplifi er will be that of the connected speakers only.

4.) Power Input

Th

  is unit features a hardwired AC power cable and externally-accessible fuse. It is supplied with an 0.75 A, 250V 

fuse and USA-type polarized 2-pin plug. Th

  is unit is not suitable for 230V applications unless used with a voltage 

inverter.

Controls/Indicators

5.)Power/Gain Knob (“Gain”)

Th

  is control will match the amplifi er’s input sensitivity to the output of the pre-amp source. If the source output has 

a variable control, we recommend that the user spend a moment or two determining the best balance between  the 
controls. When a balance is found between low noise, linear level control, and suffi

  cient level to drive the amp to 

the required output, the gain knob can be considered to be the “volume control” for the subwoofer system. To shut 
the subwoofer amplifi er off , turn the control all the way to the left  until it ‘clicks’. Alternatively, plug the amplifi er 
into a power strip with an on/off  switch and turn the subwoofer off  via the power strip’s switch so as to keep the 
gain knob in place. We recommend setting this knob to 10 o’ clock. 

6.) Freqency Knob (“Freq”)

Th

  is control is used to establish the highest frequency that the subwoofer will reproduce and has a range between 

60 to 180 Hz with a  slop of 24 dB per octave. We recommend setting this knob to 10 o’ clock. Experiment with the 
amount of “overlap” that you will experience when all speakers are playing in the same range. Th

  is can  be helpful 

when integrating the subwoofer with the rest of the system and with the room. Note: When using the amp with a 
LFE (Low Frequency Eff ects) output on a pre-amp or home theater receiver the internal low pass fi lter circuitry 
should be bypassed by turning the frequency control to maximum (180Hz). Th

  e home theater receiver should be 

used to control the low pass crossover frequency.

7.) Power LED

When the power switch is moved to the “on” position, the LED will illuminate green, and the amp will be in “On” 
mode. If the LED is not illuminated, check that the amplifi er is plugged into a power source and that the “Gain” 
knob is not set to the “Off  ” position.
