Question about Jensen JPS12 Subwoofer
I have a Jensen powered subwoofer(Model JPS12)that has given me a problem since I bought it in December of 2005. I've had it connected to four different A/V tuners and it does the same thing on all of them.
It emits a sound randomly (if it's plugged in) whether any media is playing or not. It actually sounds like a chainsaw or weed eater being revved up and then stops. Extremely irritating.It also happens when nothing at all is plugged into it but is itself plugged in and turned on. It happens when it is connected to the tuner by a single line OR via the speaker terminals. It even does it after I've switched it off after about 5 or 6 seconds, then fades out. There are no flourescent lights in the room or nearby, no antenna/cable wiring or unsheilded cables nearby and I've tried running it through a ground loop device but nothing seems to work. Nothing specifically seems to prompt the erratic sound.
Can anyone tell me what the problem might be? It did the same thing even when new but I was told that the tuner was the problem at the time. That's why I've tried several tuners in even two different homes on opposite sides of town. Finally, there are no power company sub-stations nearby either.
9/26/09 UPDATE!!!! : I'm finding out that others are having the same problem with this sub. Some are suggesting that it's an "auto-sensing sleep mode switch" that is causing the problem. Is there a way to rewire the on/off switch and bypass the sleep mode device?
