Delta_G Sorry I did not reply to your question re types of mics, was too focused on trying to understand the define and array declaration, I am not a programmer I'm a chemist.
I have two types of mics, thats what was available when I got them ideally I would have liked to get 4 of the same type but such is life. I have added three images two of the mics and the other of the set up I have no drawings and my had drawings suck.
