Rick Reineke Posted January 30, 2021 Report Share Posted January 30, 2021 Contact Shure and/or Zaxcom for a wiring diagram. Most lavs are not balanced, The third wire, if there is one, is for bias voltage. If it has an XLR connection, it is balanced in the transformer/power supply module. btw, soldering a Lemo is challenging... at least for me.

rich Posted January 30, 2021 Report Share Posted January 30, 2021 ive never tried wiring this mic, but from comparing a COS11 which has an audio and bias wire, my first try would be to connect blue and shield to pin 1 and red to pin 3 though i would at least solder the blue and shield together and prep the red wire, then place the solder insert into a powered up transmitter as it would if it had the outer shell, then touch the cables to pins 1 and 3. if you can hear audio, solder it up and assemble it. if it doesnt work, try with blue to pin 3 and red tied to shield and pin 1.
