Quick XLR Socket Install Question

Hello,

I have a quick question. I am building one of the ghent audio hypex case kits and I am currently trying to wire the xlr socket. I have 3 connections, 1, 2, and 3F. Based on the picture they post, 2 is the live connection (for the blue cable). Now I have a white cable (negative, I assume) and the ground from the wire itself.

My question is, do I connect the ground to 1 and negative to 3F?

Please see the attached picture for clarification.

Many thanks.

> That F by the 3 confused me.

Might be "Female".

Why? Because seen from the rear, the three terminals go 1-2-3 or 3-2-1 depending on sex. The wire-person may not see the face of the connector. An "M" or "F" on the terminals may be faster than looking at the 123/321 order.
 
On most XLR style connectors there is a fourth tab that is the chassis connection. Some folks jump that to pin 1. The careful use a capacitor for that.

The one you have does not have a chassis connection. So depending on your circuit it may have a chassis connection.

Another approach with trully balanced circuits is to only connect the shield at the send end.

I suspect you have differential inputs which are a bit different. They will work with a shield and just one other pin connected, but they work better with both other pins connected.

If confused consider the original balanced audio technique with transformers for send and receive.
