Need to make one of these, and I seem to have found conflicting resources on just how these should be wired. (I'm using canare mini-star quad BTW).
so:
pin 2 of one xlr goes to TIP
pin 2 of the other xlr goes to RING
The difference comes in how to wire the SHEILD. in a normal balance>unbalaced connector, you tie pins 1+3 together and that goes to SHEILD. So I would assume (and found a resource or two that implied) that SHEILD should go to pins 1+3 of both XLR connectors. However, in some diagrams, it only goes to 1+3 of one XLR.
So does it matter?
