I'm just a little confused on the correct way to wire the Neutrik Combo Jacks in my vocal/amp booth wall plates. They are XLR/TRS combo jacks. Pin setup is listed below: XLR Pins: 1, 2, 3 TRS Pins: TN, RN, SL Other Pins: G Here are my questions: 1) I have 3 pins for TRS and 3 pins for XLR. I know that those need to be matching, but can I simply wire it with one 2-conductor shielded mic cable, and then jump the terminals from XLR to TRS, or is it better to wire 2 seperate cables (XLR-XLR & TRS-TRS)? 2) There's an extra ground pin. What the heck do I do with that? Do I jump to it from the "sleeve" pin, or do I connect with a totally seperate ground wire? Thanks in advance for your help on this.
