Loud hum once powered. with or without imputs. No audio, just hum. Tried multiple power cables and sockets.
SOURCE: Acoustimass Subwoofer has a low "hummm" sound when turned on.
Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.

The master on/off switch will usually be on the back (or maybe even the bottom) of the largest component, which contains the power and control circuits.

I will try as best I can... There is no light on the unit. There is a two position switch, that's your on/off switch located on the botttom of the unit next to the pwr cord input... When the straight lined side is pushed down the unit is energized. When you pwr up the unit you should hear a light bump, not a cracking noise. There is a fuse on the main input/output board that is pretty easy to pop and swap.

You can buy it on ebay but it's cheaper just to make one. If you can solder, all you need is a female 15-pin d-type connector and a bunch of speaker wire. Here is a diagram of the connections.
