So assuming the patch cable I'm using is correctly wired its Orange and white pin 1 to xlr pin 3
Orange pin 2 to xlr pin 2 , and brown and brown and white pins 7 and 8 to xlr pin 1. and if only 2 wires are used, the connection to pin1 on the xlr will be redundant and have no effect.
and if I build an xlr3 terminator its 120 ohms across pin 2 and 3.
