Important!!!
Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!
Volume Contr ol
This control allows you to balance the output from the subwoofer to the main speakers/amplifier in your system. This control should be set to achieve similar output level from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is 3 or 4 dots from minimum.
Low - pass Cr ossover - 40 to 120 Hz
All inputs sum the left and right channels together, with the resulting signal passing through an adjustable
A bypass switch is also provided if you wish to use an external crossover. If you are not using
an external crossover, we recommend that you use the one provided within the unit for optimum performance!
Phase Adjustment - 0°/180°
This control allows you to “reverse” the phase of the subwoofer’s output signal 180° to correct for any possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with music playing. Then move the switch from one position to the other and listen for a change in low frequency output. The correct position will have a greater amount of apparent low frequency output.
Cr ossover Switch - INTERNAL X - OVER/SUBWOOFER DIRECT
This switch allows the internal crossover circuitry to be removed from the signal path. This is required in certain installations which route the signal through external processors with a crossover circuit of their own, such as the new digital units. Simply move the switch to SUBWOOFER DIRECT to disengage the
