Connecting To Digital Home Theater Systems - Boston Acoustics XB6 User Manual

Connecting the Subwoofer to Digital Home Theater Systems
Digital 5.1, 6.1 and 7.1 home theater electronics dedicate one channel (the ".1") to reproduce the special low-fre-
quency (LFE) information (such as explosions and thunder) contained in digitally-encoded soundtracks.
Select "subwoofer-yes" from your receiver's set-up menu. Hooked up this way, the receiver's amplifier is relieved
of having to reproduce the difficult low bass signals that can drive the receiver into audible distortion.
Use an RCA cable (not included), as shown, to connect your digital receiver's subwoofer output to the subwoofer.
Connect the other end to the XB6 or XB8 jack labeled "bypass crossover control" underneath "line level in".

Powered Subwoofer Featuring BassTrac
* use crossover control: removes high
frequencies; use with sources lacking suitable
filtering (most products without Dolby Digital
or DTS), or where manual control is desired.
CAUTION: Disconnect supply cord
before replacing fuse. For continued
protection against risk of fire, replace only
with same type fuse.

If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect the subwoofer in parallel
with your main speakers (see diagram below). The subwoofer does not present any additional load to your receiver.
Select "subwoofer-no" from your receiver's set-up menu. This sends the LFE signal to the main left and right speakers,
and thus, to the subwoofer. Consult your receiver's owner's manual for more details.
When using the speaker wire hookup, the subwoofer's built-in crossover is engaged. As a starting point, set the crossover
control on the subwoofer about 10Hz higher than the lower limit of your main speakers' bass response. Fine-tune the
crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover control will
depend on speaker placement and personal preference.
