Operation
Power On/O
Plug the subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Set the power switch to
the desired setting.
OFF – The subwoofer is off and will not produce any sound. You may want to turn your subwoofer off if you will not be using
it for some time or wish to conserve electricity.
ON – The subwoofer is always on.
MUTE – If no signal is detected after several minutes, it will automatically enter the Mute mode.
An LED indicator between the Power switch and the Polarity switch indicates what mode the subwoofer is in.
OFF – The subwoofer is off
RED – MUTE (No signal detected, Audio Off)
GREEN – ON (Signal detected, Amp On)
The subwoofer will automatically enter the Mute mode after several minutes when no signal is detected from your system.
The subwoofer will then power ON instantly when a signal is detected.
Crossover Control
Adjusts the frequency of the low pass filter for the subwoofer. Set the crossover control on the subwoofer to 180Hz.
Volume Control
Turn the subwoofer Volume control to the 11 o’clock position. If the subwoofer makes no sound, check the AC-line cord,
Power switch, and input cables. (Are the connectors on the cables making proper contact? Is the AC-line cord connected to a
“live” receptacle, is the subwoofer in either the Auto or On position?)
Adjust the subwoofer Volume control until you hear a match between the main speaker and subwoofer. Bass response should
not overpower the room but rather be adjusted so there is a natural blend across the entire musical range.
Polarity Control
(0° or 180°): Selects regular (0°) or inverted (180°) phase 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.
Maintenance and Service
All wiring connections should be inspected and cleaned or remade at least once a year.
If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one
loudspeaker, rewire that speaker in a different location within the system. Should the problem persist in this speaker the
problem is within the speaker. If the speaker sounds fine in the new position it is a strong indication of a more in depth issue
with the electronics in the system. In the event that your SoundWare XS 5.1 ever needs service, contact your local Boston
Acoustics dealer or visit bostona.com for a list of dealers in your area.
If your subwoofer does not play, check that all the connectors on the cables are making proper contact and that the AC plug
connected to a “live” receptacle.
