I use the USB Soundblaster MP3 device... we occassionally got a hum from the puter before... maybe a bad ground in the electrical wall outlet. Some venues were worse than others..

But with this device, I've not yet had a problem at all!!

Good Idea! I have that and have never used it.

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?

With most powered speakers you'd use balanced connections which don't always have XLR. There are also 1/4" TRS (Tip, Ring, Sleeve) connections that can be balanced.

Sounds like you really needed 1/4" TRS (on the mixer) to XLR on the speakers. I needed something similar when I connect my mixer to JBL Eons at one place I was doing gigs.

The mackie sr1530's have the xlr plug and so does the mixer so it worked out fine. Thx
