Boston Acoustics XB6 manual Controls

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 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.

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 sound level of the subwoofer. A typical set- ting is around 11 o’clock, as shown.

Adjusts the frequency of the lowpass 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 sub- woofer. Set this switch to pro- vide the fullest, most dynamic bass. The effect of phase will be most audible on low-fre- quency percussion instruments or music with a continuously repeating bass line.
