I am helping my church install new 1/4 inch and XLR wall jack on our stage to run back to the board. We are putting running the to a DI and to a snake that will feel to the board. I have a good bit of soldering experience but not with these things and I was hoping you guys could help me out with some diagrams because the ones I have tried following have worked but when you touch the plate you a a big hum. We are running 1/4 female to 1/4 male, XLR female to XLR male, and XLR female to 1/4 inch. We got sound out of it but when the plate touch other metal or anything it could ground to (ie me) it buzzed really bad.
 
Ground loop.

Isolate the grounding plate, or lift the ground on that DI.
