XLR isn't made or used for high power and the losses post amplification over long distance makes this a tricky problem.
For sure, it just sounds like this isn't amplified (maybe I missed that). The 1 pin would be a 'ground' less than a 'shield'; I'm not sure how the whole common mode rejection thing would work with a conductor that's not a shield...so I probably should have put a heavier emphasis on the 'try' part.
