Static in speakers

How do you get rid of static in the speakers?

  • Anonymous Mar 22, 2010

    No, I mean static. If I turn the receiver on and off several times, I can get the static to go away almost totally but there may still be one pop every 6 or 7 seconds, but it is a pain in the ^&%. Then if I change from one setting to another, ie DVD to TV, the static starts up again at a crazy level. I have had people tell me it is the connections so I redid them with the ultimate of care or that it was the speaker wire but the wire has only been used about a year before this problem started and I haven't used the receiver since so i find it hard to believe the speaker wire is bad. ANY OTHER SUGGESTIONS?

I own this receiver, I assume you refer to the "hiss" rather than actual static.

I've found it seems to be related to temperature/humidity changes especially going from warmer to colder. And it is more pronounced from the analog audio outputs. Here is what I've done to remedy the problem quite effectively and the noise floor is now very very low, inaudible in fact.

Don't turn it off. You don't have to be powering anything with it, just leave it on. It doesn't have a standby mode but leaving it on will help keep it a constant temp. It doesn't produce much heat at all even when playing very loud.
The digital outputs are considerably quieter than the analog outs. I haven't completely remedied the problem with the analog outs.
Use ferrite clamps on the power cord and the analog audio outputs. Three on each helps.

You may notice that if you turn it off for a while, or your room gets cold or humid it gets more pronounced even when the above tips are employed. In this case I've discovered that simply playing it, let it "warm up" for example while movie previews are on at a moderate level, can make it go away.

Turn off you computer and pull out your sound card if it is external. Then plug it back in the same hole. It may just be loose. If this does not help try another card. If you have a built in sound card try installing updated drivers for it from the manufacturers web site.

Static audio on GigaWare VGA PC Camera

Normal 0 Two things can cause static.
First, If you have your speakers turned up to high it will give you feedback causing distortion and static. I recommend using a headset when videoing.
Second reason is, if you are using a laptop and have added an external microphone between the two it will cause distortion and static.
Not knowing the configuration of your computer makes it harder to analyze the problem.
So hope this is of some help. Bud
