Non inverting polarity?


Can someone explain what the difference between inverted and non-inverted polarity. What does it have to do with the # 2 or #3 pin being hot on a XLR ic.

There are 2 issues being discussed. I think Husk was asking an electrical question about the pin-outs on XLR connectors. I vaguely remember something about not all brands being wired the same, which could cause problems mixing different brands of equipment (maybe tieing signal to ground?). Someone with specific electrical expertise needs to answer this.
The other thing being discussed is the effect of absolute polarity on sound. I never believed it mattered (i didn't know why it would). After talking to someone who was convinced otherwise, I tried it out (since my remote has a phase switch). I chose a recording, decided which phase I preferred, then looked away, and repeatedly hit the phase switch while waving the remote around, so that I had no idea which way the player was set. Then without looking, I switched back and forth until I again picked my favorite setting, which was the same as the first time. I have tried this experiment about 10 times, and have always been consistent (that is, picked the same phase blind as before), on recordings on which I thought I could tell a difference (I could tell before the experiment whether I could hear a difference or not). Many recordings I cna't hear a difference on, though, and when I can hear a difference, it is so subtle, even I wouldn't be convinced, except for the results of the blind listening tests. It is so subtle, I don't really think about it while listening. My 2cents.
Eldart - I agree - I didn't believe it until I tried it, and then kept trying it, and the perfect results forced me to believe. I don't know why it should matter - either way the cone is moving back and forth, many times to make even the quickest note. I can't imagine how I could tell which direction it started. I didn't want to believe it, for fear that I would become paranoid about which way each recording shopuld be played (as had the person who convinced me to try it. He was so into it, he said he could not listen to one recording because the vocals were recorded in correct polarity and the piano in opposite polarity! I felt so bad for him!)
