Got Static?

All:

I am completely vexed and need some suggestions....

The problem: I am hearing occasional "ticks" which I believe are associated with static buildup in my system. The "ticks" occur randomly, roughly one to three times during the playback of a CD. I hear them during vinyl playback as well but it is sometimes hard to distinguish them from surface tics or pops. These "ticks" can sometimes be heard when the system is idling with the mute button disengaged--when the mute is "on" they cannot be heard. The frequency of the "ticks" appears to increase as the humidity level drops--the colder and dryer it is the more of them I hear. Thus, the problem is less of an issue in the summer (unless running the AC) and is pretty darn annoying in the winter. Sometimes, when I touch my gear I receive a small shock which is translated by the speakers. I have tried to ground my rack but this has not helped. Believing it may be a grounding issue I have also tried cheater plugs on my CD player and/or linestage--no change. The funny thing is I have been at this for 25+ years (with many different system configurations) and this issue has never been a problem until the last year or so--can't figure out why it has become one now.

Any ideas about WHAT is causing this and HOW to stop it? Anyone else have this issue?

Have you changed any cables recently? If so, perhaps you have introduced a cable not as well shielded as what you had previously. I have experienced this with a cable that was picking up ticks from light switches turning on. That little bit of arcing at the switch creates an RF emission that can picked up by a cable (think antenna). Another source of RF ticks might be motors switching on--like your heater blower, etc.

I had a problem with static as well. I bought a 4" X 2" rectangular static discharge mat which I keep in the top of my rack. It grounds to the screw on the wall outlet. Before I touch the system, I tough the mat and it discharges the static. I get no static through my system now and I did before I started using the mat to discharge myself first.

If you think about it, when you build up the charge and just touch the system and get zapped, that discharge seems to do something to the system and you can get those annoying static sounds.

I bought it on-line a couple of years ago for like under 20.00. I find it indispensable. Don't remember the site, but just Google static discharge mats.

Have you tried using a humidifier? Since you mentioned the problem is related to humidity...

I started a thread about this last year (maybe the year before, not sure). I too have crazy static problems here in Colorado. I couldn't figure out how to battle it. I tried everything. I'd get audible pops sometimes just walking across the room. All my cables were off the ground, I tried fabric softener, I tried humidifiers, I checked my ground, I lit candles and danced around the room and offered sacrifices to the static gods... Nothing worked.

Soooo, I put a coin next to the light switch and hold it in my hand whenever I ground myself on a screw under the light switch.

By brother lost two preamps last winter due to static in his home. The summer before his house got struck by lightning and he lost his whole stereo in addition to his stove and many other electrical items.

Static is a drag...

Thanks for your contributions! The room features hardwood floors with a large area rug--you can see some photos of the room if you click on my virtual system. This comment by Stereo5 has me wondering...

"If you think about it, when you build up the charge and just touch the system and get zapped, that discharge seems to do something to the system and you can get those annoying static sounds".

whether the "ticks" are a result of static that is building up in the system components without encouragement or whether I am introducing the static by touching the system thereby transferring it to the components which then reproduce the "ticking" sound. If the latter were to be true it would have to be lying there dormant somehow until enough of a charge builds up to release a "tick". Is this even possible? And why has this become a problem only in the last year or so when I have had the system set up exactly the same way in the room for five years and did not experience the static problem until just a year ago? I have changed components over the past five years--could one of the newer ones be more "susceptible" to static discharge than the others? Thanks for your help!
