XLR to 1/4" TRS Connector (wired for balanced mono)
The usual way to connect a 3-pin XLR to a 1/4" TRS (AKA stereo jack plug) is to use the following pin allocation:
- XLR pin 1 to jack sleeve
- XLR pin 2 to jack tip
- XLR pin 3 to jack ring

This wiring configuration gives you a balanced mono audio cable.
