To alleviate this condition, we recommend the following steps:

1)If using line level jacks, BOTH THE LEFT AND RIGHT INPUT CAN BE USED – never use just the left or just the right input. If the subwoofer’s signal comes from the LFE channel of your receiver, use a “Y” splitter to connect to both the left and right 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. (See figure 2a on page 7.)

* This dual male-to-female “Y” splitter can be found at your local electronics store.

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. (See figure 2b on page 8.)

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.

I m p o r t a n t ! ! !

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.

Volume Contr ol

This control allows you to balance the output from the subwoofer to the main speakers 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.

Warning:

Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly.
