[. . . ] In the latest digital formats, bass information is recorded not just in the front channels, but also in the side and rear channels. You can enhance the impact of any BT system, and the realism of the cinema experience, by adding rear or side subwoofer channels. The installation versatility of the BT1100 makes it easy to fit multiple subwoofers into almost any room. Most systems will use one of the "line level in" jacks on the BT1100. These inputs accept the line-level signal from your receiver's or processor's subwoofer output. The Bypass input is designed to accept a summed low frequency signal from the LFE or subwoofer output on a receiver or processor. this input bypasses the BT1100's crossover , relying on the bass management circuitry in the receiver or processor. This connection is most commonly used with Dolby Digital or DTS receivers and processors. Connect a single RCA from the LFE or subwoofer output on your receiver to the LFE input on the BT1100 (see diagram #1). This input uses the lowpass crossover built into the BT1100. Refer to the section on setting the crossover for more information on proper tuning of the lowpass crossover. This connection is most commonly used with Dolby Prologic or Stereo only receivers and processors.

The speaker level input allows you to integrate the BT1100 to a system that does not have a specific subwoofer or line-level output. As the speaker level signal is full range, you will need to use the lowpass crossover built into the BT1100. Refer to the section on setting the crossover for more information on proper tuning of the lowpass crossover. This connection is most commonly used with Dolby Pro logic or Stereo only receivers and processors that do not feature a subwoofer or line-level output. NOTE: Certain receivers use speaker grounding circuits that may be incompatible with external powered audio products. This incompatibility can sometimes result in an audible hum when the receiver is turned off or switched to a different speaker channel. Connect a pair of speaker wires in parallel with the main (left and right) speakers (see diagram #3). [. . . ] Even our rugged speakers can be damaged by an amplifier if it is producing distortion. If you hear a harsh, gritty sound, turn down the volume. Prolonged or repeated operation of your speaker with a distorted signal from the amplifier can cause damage that is not covered by the warranty. First, contact the dealer from whom you purchased the speakers. [. . . ]
