I'm not familiar with the Pass amps specifically, but assuming it is an XLR-female, oriented as you describe, if you are facing the pins normally pin 1 would be at 9 o'clock, pin 3 at noon, and pin 2 at 3 o'clock.
If by any chance it is an XLR-male, the arrangement would be the mirror image of that (pin 2 at 9 o'clock, pin 3 at noon, and pin 1 at 3 o'clock).
Also, if you haven't already, take a close look at the connector, with a magnifying glass if possible. I suspect that you'll see numbers marked next to the pins.
