XLR Pin Vocabulary


Some manufacturers describe XLR pin polarity in a vocabulary of ground, non-inverting, and inverting. Others use a different vocabulary, ground, negative, positive. How does one translate into the other?

One more note: Industry standard is pin 1 is ground, pin 2 is non-inverting (+) and pin 3 is inverting (-). Some manufacturers do not recognize the standard (we've even seen some using pin 3 as ground) but usually the only significance is that the signal might get inverted if only one of two products connected together is on the standard.
50% of your recordings are out of phase anyway. I would not worry about it too much, unless they are all 2-mic recordings, in which case a phase inversion switch would be handy.
