Asian Standard??
Originally the balanced line connection standard was pin 1 ground, pin 2 non-inverting and pin 3 inverting. This is now known as the American standard, and was typical of any professional audio equipment made in the US during the 50s and 60s.
Sometime during the 70s or 80s there emerged the European standard, that has the phase reversed (but you can always count on pin 1 being ground).
