Volume Contr ol

To alleviate this condition, we recommend the following steps:

1)If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED

– never use just the left or just the right input. If the subwoofer’s input comes from the LFE channel of your receiver, use the included “Y” splitter to divide the single input into two inputs for the Left and Right subwoofer inputs. If using line level connections from a preamp or signal processor, use both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer.

2)If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to the subwoofer. We recommend setting the subwoofer’s level to the 9 o’clock position (the 1/4 volume setting) and then adjust the LFE channel on your receiver or processor to achieve the desired bass output. See your receiver or processor’s owner’s manual for more information.

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. If using the SPEAKER LEVEL inputs, you DO want to connect both channels, since different bass information might be present in each channel going to your main speakers.

IMPORTANT!!!

Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

Caution!!! To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections - red (positive) to red, and black (negative) to black. Be sure all connections are tight, and that there are no loose strands or frayed wires.

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 levels from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is two or three graduations from minimum.

Low - pass Cr ossover - 50 to 200 Hz

As noted above, 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 50 to 200 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.
