I have a Mackie 3204 Sound Board and i am tring to get a A-T Pro 37R condenser mic to work for a overhead drum mic. I cant figer out why it is not working. I know the mic works becuase i have tested it on another sound board. It just does not work on this one. The hole sound system is wire Balanced. We use the 1/4 jacks out of the Sound board instead of the XLR out puts. Could that be why it is not working and does anyone have a way i could fix it?
