4 pin XLR, is the 4th pin needed?

[Chris Jordan]

I am wondering if the 4th pin is needed! Here is the diagrham for the power to the Scarlet, and ther is 2 of +and 2 of -. Do they do diferent things, or can I just combine them to go 1 + wire and 1- wire...? Wonder how the p-taps to lemo 1b are wired.... I did call Red to ask, but they "didn't know".

Hi Chris, I've wired up many 4-pin XLRs as well as P-taps. I don't fully understand your question, so Just give me a ring and I can try to assist you.

The two +ve and two -ve connections ARE necessary on the Red end!!

4 pin XLR power usually only uses pins 1 and 4 for the Ground and +12Vdc respectively .

Do not attempt this without knowing for sure what you are doing or you will expensively damage your camera!

Hi Chris, if you don't mind, tell us all what you do, ie which lemo pin you connect to which xlr pin as its something a lot of people are likely to want to know.

MArcus, I just confirmed Erics statement above. It is correct:
