Trying to figure out how to wire XLR pinout to Weco connector for LTC input on Carbonite Ultra.  The manual shows the 3 connectors on the Weco as LTC-, LTC+, LTC-.  How does that translate to the XLR cable pinout?  Thanks. 

We would probably need to know what is providing the LTC source and then we can look at the pinout they provide..

Just grabbing from ETC I see this

Since we are showing 2 x LTC -  and 1 LTC Positive I would wire it pin 1 and pin 2 to the WECO LTC - and then go with Pin 3 to LTC +

It that does not work .. then I would go for a 1-1 / 2-2 /3-3 since the Balanced to balances pinout has Com/ Shield on 1 and Signal - on 3 ..  with Signal + in the middle.
