Wiring XLR connectors in Wall Plates - Grounding path to Mix

phyl · Post by **phyl** » Sat Jan 14, 2006 5:07 am

I have a wall plate in my tracking room that will house 12 XLR connectors. 12 channel snake wire runs from this wall plate to another wall plate in the control room. From there I'll build short snakes to connect the mic lines to my mixer.

The wall plate XLR connectors have metal bodies and a lug that could used to solder a ground wire to in case you wanted to ground the connector body.

Should I tie all these lugs together in each wall plate, use the master ground wire in my snake to connect the two plates, then run a wire to the mixer ground? This would connect all the connector bodies to the mixer ground.

Or maybe the connector bodies in each wall plate should float.

Hello Phil,

I wouldn't worry about the extra Ground, unless you have issue's. Just wire pins 1, 2, and 3. (pin 1 shield, pin 2 hot, pin 3 common). The additional snake wire is sometimes used, but most of the time, it's not.

Thanks Aaron, that seems to be the consensus.
