before replacing fuse. For continued
protection against risk of fire, replace only
with same type fuse.
ATTENTION: Debrancher avant de
remplacer le fusible. Utiliser un fusible de
rechange de même type.
* 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.
** bypass crossover control: direct to woofer;
use with sources having built-in crossover
controls or bass management (most products
with Dolby Digital or DTS).

Connecting the Subwoofer to Stereo or Dolby
®
Pro Logic
®
Systems
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
control. 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.

Adjusts the sound level of
the subwoofer. A typical
setting is around 11:00
o’clock, as shown.
Crossover (Hz)
Polarity (0° or 180°)
Completely turns all power
to the amplifier either on or
off and over-rides the power
mode switch. This switch
must be turned on before
setting the power mode
switch (see next page).
Adjusts the frequency of
the low-pass filter for
the subwoofer. This
control is inactive when
using the “bypass crossover
control” input jack.
Selects regular (0°) or inverted
(180°) polarity for the
subwoofer. Set this switch to
provide the fullest, most
dynamic bass. The effect of
phase will be most audible on
low-frequency percussion
instruments or music with a
continuously repeating bass line.
