I need some ideas to get this noise to stop, I have a EPRAD Starlet processor/amp. that has a poping noise in the sound each time the Potts platter brain microswitch in engaged, all three platter brains are doing this, the automation is a Xetron Maxi-8, every one of the manual switches do the same poping noise in the sound, I found no ground wire is run to the projector, automation, sound, & electrical plugs, the ground is being supply by the conduct & raceway....I tried using the conduct for ground to the sound system & platter, but no work, poping noise is still there, I am going to try the .1 mfd @ 600v capacitor idea across the microswitches tonight & see if that will stop the noise from the platter brains....question is would this help, if so wher do I connect the capacitor, across the microswitch terminals, or to the platter & one contact on the switch ?? Would getting an electrican to run a ground wire to the automation, projector, platter & sound system would help & stop this...any ideas from you guys is much needed....thanks....

Thank you Mark, Gordon & Ken for the help, working in a small town (I can tell I'm not in Houston) I could not find a .1 cap anywhere...Mark, the platter & sound system ( I think eveything is all on the same phase, only two circuit was run to power everything I will take this advise...
Gordon..thanks for the input info...& Ken I will have to checked into the phase control...by the way what is the phase control ??? that is the first time I heard of that...
Here is what I did to elimate the noise..not the pop but the buzz noise...I connected the shield & the neg. together at the processor end, & connected the shield to the soundhead frame...thety are using exciter lamps & stereo solar cell...the poping noise also went low, low enough for me to hear knowing what to listen for, but not enough to get anymore complaints from the patrons, I still want to get rid of totally, but for now it is OK, on my next visit I will elimate the poping noise..I had made notes on the input from you guys, thank you so very much for the help...have a great Christmas....Don
