Care of your speaker
Your new subwoofer/-s does not require any regular maintenance or calibration. Normal dusting or
cleaning of the surface for appearance purposes is all that is required.
Cabinet and baffle
Avoid using harsh detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or
cleaning solutions may damage the finish on the cabinet. We recommend using only a damp cloth or
automotive grade “quick detailer” designed for painted surfaces, plastic & metal trim, to clean the cabinet.
Grill
The cloth grill may be carefully cleaned using a vacuum. Animal hair can be removed using masking
tape or similar. Avoid using brushes with stiff bristles that may damage the grill cloth.
Woofer
DO NOT use liquids, brushes or a vacuum to clean the drive units.
Protection circuitry
Your new subwoofer is equipped with special protection circuitry to provide maximum performance
with greatest reliability.
The unit is protected against:
1)
Overdriving the speaker or amplifier.
2)
Overheating the amplifier.
3)
Excessive drop in power line voltage.
The first type of protection circuitry which prevents overdriving of the speaker or amplifier operates
constantly without being audible under most situations. In some extreme situations (e.g. sustained high
output levels in warm environments), the unit may shut down momentarily. This indicates operation of
the thermal or undervoltage protection circuitry. If this should happen, you should reduce the volume
setting or shut the unit off until normal operating conditions return. You may also want to plug the unit
into a different wall outlet (or circuit), as inadequate power line voltage & current will be most noticeable
under high output conditions.
Power Indicator Light (10)
This LED indicates the operating mode of the subwoofer. Green indicates normal “ON” operation. Red
indicates the subwoofer is in a low power “standby” mode.
Power Switch (11)
The master power switch is located on the lower half of the unit. This rocker style switch is the main
on/off for the unit. This switch should be set to position 1 (up) for on, and 0 (down) for off. If the unit is to
be left unused for an extended period of time (e.g. when you are away on vacation), the master power
switch should be turned off, or the mains power cord disconnected.
