Re: Subwoofer hums under power not hooked to system &...

This may or may not apply to your particular problem. On similar humming sound problems, I normally would look for either a fault in the input side and/or a leaky/defective capacitor in the power supply. On the input side, this may be a frayed shielded wire, loose connector (esp. the outer which is normally the ground). Try completely removing the connecting/input cable that goes into the subwoofer. If that doesn't work, then it you may want to check the big capacitor in the power supply section of the subwoofer. If you are not that familiar in working with power supplies, may I suggest that you ask any electronic technician to have a look at it since capacitors store a rather hefty voltage. Better be on the safe side. Hope this works out ok with you

Loud humming sound

Make sure that the input connection ground is good. If that does not cure the loud hum then you have a power supply issue.

Philips spa2360/17 subwoofer making a humming noise

Check your audio and electrical connections. This may be a bad cable connection. Also, so not run the power line and audio cables in parallel. They should only cross at 90 degrees, to reduce induced power hum.

Double check your wiring again, sounds like something is either not hooked up right or maybe you got faulty speakers. There shouldn't be any hissing or humming in any speakers. Get a flash light and make sure you have it in the right spot on your computer most sound cards have about 5 different jacks you could have simply put it in the wrong jack.

Your "line in" from speakers should be plugged into the green (output) port on the back of your tower or the headphone jack on laptop. You will need to hook the 9 pin connector from the right speaker to the subwoofer. The yellow line from left speaker plugs into port labled "subwoofer" on subwoofer. Plug your power cord from speaker system into an outlet. Turn them on, adjust volume. There is no software for this product.

Loud hum when Bose Companion 3 Series II speakers are turned on.

I had the same problem for many months. I asked a sound & video professional and he suggested I move the subwoofer away from any power source. I had the subwoofer next to my UPS. Once separated and moved all wiring away from the power supply (about 12") the low bass hum was practically gone.

Humminf sound from subwoofer

Most humming sounds in speakers is due to electrical currents or wifi signals nearby the speakers.

Do you have any electrical cables near the speakers? Do you have any wifi device near the speakers?

If so move them out/away and see if there is any difference.

Loud humming coming from 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.
