Connecting Your 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 are used for connecting to a 5.1 home theater system. See the illustration at the
bottom of the facing page.
When using speaker wire or the “Crossover Int” 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. 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.

Bass Level Control
This control adjusts the sound level of the subwoofer. It is located behind the grille on the front
of the cabinet. Grasp the top and bottom edges of the grille and pull the grille straight off the
front of the cabinet. A typical setting is for the control is around the 12 o’clock position. See
the information in the preceding sections on connection for more details.
Crossover Control
This control, located on the amplifier panel on the rear of the cabinet, adjusts the frequency of
the low-pass filter for the subwoofer. See the information in the preceding sections on
connection for more details.
Polarity Switch
This switch, also located on the amplifier panel on the rear of the cabinet, selects regular (0
°
) or
inverted (180
°
) polarity for the subwoofer. Set this switch to provide the fullest, most dynamic
bass. The distinction of phase will be most audible on low-frequency percussion instruments or
music with a continuously repeating bass line.
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged. The auto-
on circuitry only activates or deactivates the power amplifier.
