Boston XB6 Manual De Instrucciones página 6

Connecting the Subwoofer to Stereo or Dolby
For stereo or Dolby Pro Logic systems, the easiest method is to use the same speaker wire connections as shown on page 5.
You may also use the "sub out" connection from your receiver to the input on the subwoofer marked "use crossover con-
trol." When using speaker wire or the "use crossover control" input, 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 (for Boston Acoustics front speakers, refer to the included "Optimal Crossover Settings..."sheet).
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.

* 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.
