Has anybody ever used this to make XLR cables? http://www.markertek.com/product/72401ez-bk/gepco-72401ez-2-cond-24-ga-twisted-pair-audio-cable-black-per-foot
I was thinking about trying it because I have some spare Neutrik connectors lying around collecting dust. If I do get some, would the red go to pin 2, and the black to 3, or the other way around? Or would it not matter as long as I'm consistent from one cable to the next? Also, I suppose the drain wire on this cable would go to pin 1 as the ground, but would I tie that first to the foil shielding before soldering it or not use the shielding at all? Most cable I've used in the past has a blue, a white and no separate drain wire, so I use the blue for pin 2, the white for 3, and the shield is what I've always used as the ground.

When in doubt, check the Rane cheat sheet. Red or White for 2 and Black for 3 is a common convention. Electrically the same Red on 3 but following convention helps in repairs and troubleshooting.

The drain wire is convenient, use a continuity tester to see if it is tied to the shield. If not continue using shield as you have in the past.

Thanks much. Just to make sure I understand, are you suggesting that if the shield and drain are not tied together, to use the shield for pin one and ignore the drain wire?

From the description on Markertek page...
Foil shield with same gage drain wire facilitates quick shield termination. Twenty-four gage conductors are easier to terminate while still maintaining low DCR. Ideal for patchbay wiring or mobile production trucks.
The Foil Shield I've seen in the past were polyester film with aluminum surface and included the drain wire...how is that handled?

Take a simple voltmeter and test for continuity between the drain and shield. If they are tied then go ahead and use the drain.
