Hello Jimmyjames - on a prior post you advised the Marantz SA11S1 inverts polarity on the balanced out. The manual states the SA11S1 uses the US standard, with pin 3 as Hot. Is the manual wrong? Or is this an issue due to your amp/preamp using the European standard? Thanks for any input - hopefully I actually understand your prior post correctly. This balanced stuff is confusing sometimes.

Err?The Marantz Sa11S1 manual shows a pin config for supposedly a US standard female XLR and a European stnd. female XLR. In the Marantz manual it says US stnd. is pin 3 hot, Euro stnd. pin 2 hot.
Googleing AES/EBU XLR pin assignments shows pin 2 (+). The AES is not necessarily a US stnds agency but the US audio profession widely accepts it's standards. And of course the EBU is the European Braodcast Union.
My Mark Levinson 380S preamp manual says pin 2 positive(+)???.
I would suggest that pin 2 + or hot is the US/AES/EBU american/european stnd.
Another poster a long while ago suggested the Marantz manual was wrong as to the US stnd. and suggested a pin swap on end of each XLR cable to achieve correct polarity. I listened to it both ways and went with the cable pin swap on 1 end of each xlr cable.
If you had an all Marantz reference system as currently manufactured, you would leave the xlr cable ends alone and be correct, I guess. At least that's what the local Marantz dealers say.
If all of the above is correct, then the Marantz (and possibly the Asian standard) is pin 3 hot.
It's also the standard in Europe.
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.
