the pinout of an XLR is one of my knowledge. At least I can find docs explaining without too much problem.
I was more thinking of something like this:
in which one can find active circuits to pass a balanced signal into an unbalanced one, and vice-versa.
So I was thinking of using such schematic in front of the input of the pim, maybe with a selector switch to select a second unbalanced input.
Now I would like to keep balanced line through the pimeta, so I should pick up the signal, and have it re-balanced to an output.
So, Anyone with suggestions for this is welcome.
