Boston Acoustics MCS 130 Subwoofer Controls, Operation, Power On/Auto/Standby, Volume Control

Subwoofer Controls

Power On/Auto/Standby

Plug the subwoofer AC cord into a wall outlet. We do not recommend using 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.

AUTO – The subwoofer will power on whenever a signal is detected. If no signal is detected after several minutes, it will automatically enter the Standby mode.

ON – The subwoofer is always on.

An LED indicator next to the volume control indicates what mode the subwoofer is in.

OFF = The subwoofer is off

RED = STANDBY (No signal detected, Amp Off )

GREEN = ON (Signal detected, Amp On)

The subwoofer will automatically enter the Standby mode after several minutes when no signal is detected from your system. The subwoofer will then power ON instantly when a signal is detected.

Volume Control

Begin by adjusting the Subwoofer Volume Control to the 11 o’clock position. Further adjust the Subwoofer Volume Control until you hear a match in volume between the main speakers and subwoofer. Ideally, bass response should not overpower the room but rather be adjusted so there is a natural blend across the entire musical range.

Polarity Control

Selects regular (0°) or inverted (180°) polarity for the subwoofer. Set this switch to the position that provides the fullest, most dynamic bass when auditioned from the primary seating position. The effect of polarity will be most audible on low-frequency percussion instruments or music with a continuously repeating bass line, and may not produce a dramatic change at all.

Operation

When using the MCS 130 in a Dolby® Digital or DTS™ home theater system, make sure all speakers are set to “Small”. When using the system in a Dolby Pro Logic® home theater system, make sure the receiver’s center channel mode is set to “Normal.”

Some receivers/processors offer different setup options for each source or surround mode (e.g., CD-stereo, videotape, Dolby Digital, Dolby Pro Logic). In each case, follow your equipment’s instructions to ensure that the subwoofer output is turned on and that the speakers are set to “Small” in each mode.

If your receiver has adjustable crossover settings, we recommend the subwoofer crossover be set at 120Hz.

Refer to the owner’s manual for your AV receiver for any additional recommendations on system operation.
