[sdiy] Hum Problem Kaput

[Jay Schwichtenberg]

Lava,

My line mixer and Mackie do not work together. They'd turn into a 60 Hz
generator when I plug them together no matter what I did. I got a Ebtech 2
channel hum eliminator. That got rid of all the problem and there are
several other times I've used it between gear to get rid of ground problems.
My friend that does live sound borrowed it and ended up getting one for
himself. He always seems to be using it for something.

Jay
