is as follows:
XLR Pin 1 (GND) to cable shield and to the TRS sleeve
XLR Pin 2 (+) to one signal wire and to the TRS tip
XLR Pin 3 (-) to the other signal wire and to the TRS ring
Unbalanced Connections with Twisted Pair Cable
The wiring method for unbalanced connections with XLR connectors to
¼” phone connectors (tip and sleeve only) using shielded twisted pair cable (2 wire +
shield) is as follows:
XLR Pin 1 (GND) to cable shield with no connection on the other end
XLR Pin 2 (+) to signal wire and to the ¼” phone tip
