I n p u t s

Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, line-level crossover or receiver with pre-amp level outputs. The SPEAKER LEVEL jacks connect directly to the speaker outputs of any amplifier, integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance.

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 low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control 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, you may wish to choose a higher frequency (such as 100 -120 Hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 80 Hz.

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 built-in crossover. For all other installations which do not have a separate electronic crossover, we recommend you leave the switch set to INTERNAL X-OVERto provide optimum performance.
