Just a dumb question:

I want to build my own mic cables, & I was looking at a Neutrik XLR jack, &
it  had three
"lugs" (whatever you call those things) arranged in the middle of the plug,
& then on the outside
edge there was a regular lug.  So do I wire to the lug on the outside edge,
& if so what?
