Question about Audio Players & Recorders
I just moved and the system worked perfectly before it was disconnected now as soon as I plug the power cord into the sub it starts a loud humming. gets a little quieter as soon as I plug in the satillite speakers but is still there even though it is not even hooked up to the computer. I reinstalled the drivers in my computer for sound (headphones work fine) Sounds like they are getting to mush power???? Clueless..... Boston Acoustics Gateway Digital BA735 Speakers With Subwoofer
This can be caused due to an increase in local interference. The hum is decreased when you plug in the satellites because the interference is spread over a longer area. You may notice that speakers tend to hum around things like cell phones and power outlets. To see if this is the case, move the speakers to another part of the room if you can, slide the desk around, plug the computer in at another room, something like this. If the hum gets louder or quieter, it is interference at your new place. This can be solved by finding a new area to set up your computer stuff at. Since it's mostly the subwoofer, try elevating it off the ground, there may be a power main running under the floor.

The hum problem can be fixed in two ways.
First unscrew the 18 screws and fold out the heat-sink back-panel. Look inside towards the right and you see the ring-transformer.
Using a 14mm wrench-key you can either(1) tightened the loose bolt or(2) completely remove the transformer and with tie-wraps fix it to the rear side of the wooden triangle. Put some foam-plastic cushion around the transformer, isolating its vibrations from the box.
I now have one pretty silent(1) and one completely silent(2) bass units.

Check for improper connection or no ground like a jack thats only half in or wires reversed.

TIPDon't use a normal cable or satellite program for this; you're about to disconnect the cable that provides the audio and video for your cable/satellite feed.
WARNINGOddly enough, this solution (surge protection) can sometimes increase the humming.
WARNINGIt is unsafe to use a two-prong to three-prong "cheater" plug on the subwoofer power cord to solve the hum problem. Even if the subwoofer came with a cheater plug in the box, it's REALLY not safe to do. Don't do it.
