Re: Pin 2 Hot is the "US" standard

75.24.215.137

Pin 2 Hot is indeed the international standard. Quite a few years ago, before there was any agreed-upon standard, most American manufacturers used Pin 3 Hot. Except for microphone inputs, because that standard had been established already. This led to the paradox of mic preamps or mixers being pin 2 on the input and pin 3 on the output.

Then one of the European standards agencies decided that there should be a standard for line level connections too, and they chose pin 2. Sensible enough. The American standards bureau adopted it too, in the interest of standardisation, naturally. But they didn't ask any of the American audio manufacturers. They probably didn't know any, they just hang out with other standards bureaucrats. This led to many years of audio gear made in the US being non-conforming in this regard. Gradually the US manufacturers changed over to pin 2, and nowadays that's all you see.
