POWERED SUBWOOFER

the Subwoofer's speaker driver, the Subwoofer is the source of the hum. If you hear no hum or less hum, the problem is probably coming from another component.

Hum can also be caused by AC ground loops. If the Subwoofer is plugged into a separate AC outlet, try plugging it into the same outlet used for your amplifier or receiver, or reverse the polarity of its AC plug. If these suggestions do not solve your problems, contact your dealer or M&K.

7.If there is an unusual sound coming from the Subwoofer with no music playing:

Try removing the input cables as described in Step 5 above. If the noise disappears, it is coming from another component. If it does not go away, contact your M&K dealer or the factory.

IF YOU NEED TO REPLACE THE EXTERNAL FUSE:

Disconnect supply cord before changing fuse. Replace fuse only with same type.

Remove the fuse cap. If the fuse cap has an arrow printed on it, push the cap in and turn it counterclockwise. If the fuse cap has a slot in it, use a flat head screwdriver to turn it counterclockwise. Look carefully at the fuse. If the wire filament inside the glass is broken, replace the fuse ONLY with one of the identical size and value. USING A FUSE OF A HIGHER VALUE WILL VOID YOUR WARRANTY AND MAY CREATE A FIRE HAZARD. Plug the Subwoofer back in. If it does not work, unplug it immediately, and contact your dealer or M&K for service.
