Wired Wrongly! Please advise.

Let's just say some 96 XLR connectors were wired pin 1 : hot, pin 2 : cold, pin 3 : ground.
It should be (according to modern standards) 1: ground, 2: hot, 3: cold. The other pin configuration seems to work fine and pass phantom power, with no strange buzzes or noises even at 70 foot lengths. Is this worth going back to fix?

Oh Dear! That is a bit of a mess. You should rewire straight away. Phantom power is carried on pins 2 and 3 normally. If you plug this cable into a dynamic or ribbon mic with phantom on you will blow the arse out of as you have 48V difference between pins 2 and 3.

I agree with the above.

Its a pain but it will have been done right at the end. It shoud also only take about 3 hours to do if you just go for it.

Thats what... 4 albums worth of music. Choose them carefully.

Actually it's 192 connectors (96 channels). Well, at least I'll never make this mistake again. The soldering iron is heating up...

Assuming that both ends of the cable are miswired in the same way, then the actual signals & 48v will still show up on the proper pins, but he'll be more suscpetible to noise problems because the ground won't be connected to the cable's shield.

yeah, both ends were miss-wired the same way, and the snakes did fine through a few days of use, but now I'm in the process of re-wiring them. Thanks for the input by the way.
