sorry im a retard but could you help lonmon ? i know you used these speakers befor . would love some help

before sorry

RF sound? Are you hearing static, or hum or something else. Can you describe it a little clearer is what i'm getting at.
Describe your system - mixers, processing, etc. Using wireless mics or wired? Now what exactly are you hearing.

I think he is hearing a pearsing sound............

its kind of a ouiet pearsing sound . im using mackey dfx 12 mixer wired mikes disk changer vovopro g1 decoader . i tried pluging in 1 thing at a time to find it but it seems like it comes and goes today i could not find it could it be in the speaker

Does the system get moved around from place to place. Have you heard it at other places or just 1. By piercing sound, i'm assuming a high pitch squeal>>?

yes i heard it other places too .and i tried another mixer same results when i have my mixer off the sound is real loud .when i turn my mixer on it is much less tried diffrent outlets too

When you unplug the XLR cord from the speaker (no connection other than being plugged in & turned on), do you still hear it?

BBQ, I have a couple of solutions for you..
First thing to check is a grounded outlet. be sure you are grounded otherwise lights neons even wireless products will interfere through electricity... dont know how old you are but i remember when i was young my mom would vacumn and the tv would get all fuzzy. same concept here...
also effects and effects strips will make a problem. does your mixer have built in effects? Usually adding a hum/eliminater or plugging into a different outlet sometimes helps.. At my home I get a lil buzz/hum because our wiring is older in the home I eliminated that by getting a grounded outlet plug. It turns a 3prong plug to a 2 prong plug..
those are just a couple of things to check and eliminate ....

While this works, it shouldn't be used as a permanent situation for safety reasons. It is basically eliminating the ground altogether when you do that which can bring on a pretty nasty shock.

I'd give an address explaing the danger issues regarding that, but I had it up once & they don't want links about "safely removing ground loops" without dropping the ground prong on this site & deleted it.

I agree It is not a permanent solution but if fyou go to a venue that has a lil hum and it disturbs you. I would use it. Of course you dont ever want to use it on a outlet that is over loaded, then you are just asking for trouble..

chaz

I understand that, & I have used it myself for an evening if I don't have the proper equipment. The next time I show up at the problem show, I make sure I don't have to do the ground tab removal, it will be safe.

also i failed to mention Sheilded( did i spell that right...)
wires and coaxile.... if you use the cheap stuff as with alot of things you get what ya pay for....That could solve a many of problems...

no it sounds quiet when nothing pluged in.when i plug everything in and the mixer is off i get a lot of kink of loud hum but when i turn the mixer on noise goes away .. im going to run a new electric line this weekend to see if it helps ... dont know what else to do i will try the ground plug untill i get the new line ran thanks if you think of anything else let me know

Now that you've stated it sounds like a "hum", it's more than likely a grounding issue or a bad cord. Get an outlet tester from Rat Shack & test the outlets where you are plugging in your equipment. Removing the ground prong will more than likely silence the hum - but remember it is a dangereous move that if the conditions are right, could kill!

Are you using XLR cords (mic cords) from the mixer to the speaker? If so, you may want to try some new ones (if it works, it's a cheap fix, if not it never hurts to have back up mic cords). If you aren't using the XLR cord, then get a set to run from the mixer to speaker - (again if it works....cheap fix, if not, B/U mic cords).

If your speakers are quiet when nothing is plugged into them, then you can pretty much exclude them from being the culprit.
