The nice thing about my design is the flexibility in customization.
It can be a custom mod offered as an option. Where the locking Switchcraft DC jack shown here, can be replaced with the 4-pin XLR.
But just to be clear, it's not going to be just a $4 addition in the price. The math doesn't work that way. Now there's (3) new holes to be drilled, and manual labor (and time) for soldering wires from the PCB to the XLR pins... which is very slow (vs. soldering the PCB mounted DC jack), screwing it on, and keeping also a new part in stock on the shelves.
4 Pin XLR Pin assignments:
6V:
3 is hot (+ 6v)
Pin 2 is ground (-)
12V:
Pin 4 is hot (+12v)
Pin 1 is ground (-)
Whose standard is this??? ^^^ Just curious.
I don't have a need for a 6V supply, so pin 2 and 3 will probably be unused.
UPDATE: Is the Panel mount XLR jack a MALE? or a FEMALE?
Looking at the jack (rear view), which pin are you calling Pin #1? (leftmost, or rightmost)? and about pins 2,3,4... Clockwise? counterclockwise?
