Speaker Crackling

[GermyBoy]

It only happens when I use the knob to turn the speakers up and down. They are the Logitech Z-560's if you need to know. I'm considering RMAing it unless there is a reason it happens. I think maybe there is a problem with my controll unit.

mine do that to...its really annoying...so i just ran an rca from the line out on my sound card to an input on my surround sound receiver...that worked great!

But this isn't a receiver or anything, and the sub can't be powered except by the control panel without modifications.

Make sure line in is muted.

you may be picking up radio frequencies on the speaker wire, because it's not shielded. I used to have z560's, and got the same quiet crackling at school. When I took em home, they were fine. get shielded wire or move the positioning of your speakers.

It may just be dirt on the knob's contacts. Try, without any power to the speakers, turning the knob quickly from its minimum to full and back several times. If this doesn't clean it up, and the knob is self-cleaning when you turn it vigorously, then buy a can of spray contact cleaner.....you can find some at good ole Radio Shack.

it is dust got into the nob, just turn off the pod, wiggle the volume nob quickly for a second or two

Call them up, you prolly just have to send the control unit in and they will send you a new set...ebay the sub/speakers.

It's dust.

If it isn't a dirty volume control pot, there may be some D.C. leakage through one of the blocking capacitors feeding the circuit.

If you want to try contact cleaner, pull off the knob (gently), and see if you can see an opening around the contact area. That's where you want to spray. Turn the shaft while you're doing it.

BTW, in an emergency, I've used WD-40 as a contact cleaner.

what time of soundcard are you using?

It's a dirty potentiometer. You can clean it, but the problem will come back later. RMA it.
