Well i found out the problem. I have the Mackie SR1530 witch are powered, someone asked me what cables are you using? I said speaker 10 gauge. (like this) ---> out of the speaker with xlr plug with a 1/4 on the other side(mic cord) then to a female 1/4 then to my 1/4 plug speaker cables then to mixer.
He said you don't use speaker cable with powered speakers, use inline or whatever, they have xlr on both side. The guy said the 1 pin is the sheilding (ground). Well NO MORE HUM
Remember I am a bit new to some of this hope you under stand
anyone can you explain it better?
