HELP NEEDED - BUILDING A "SPLITTER BOX"

[Dougy]

I'm making a 'splitter box' for a micophone. Fairly simple idea, it has a XLR input for the mic and 2 1/4" mono jack outputs. One goes to the PA for live sound and the other goes to the mixing desk for recording.

I've put it together.

But I have no idea how to wire it up.

Any help would be much appreciated.
