Yes, I have used it and it works flawlessly (and sounds WAY better than the SP batt box). XLR has three connections, a "+" or hot, a "-" or drain and a ground. The ground is a shared common so what I did was use a 5 pin mini-xlr and wired it "+" to "+", "-" to "-" and shared the common ground on the 5th pin. It works.
Another side note, the mic2496 comes standard with a 5-pin mini-xlr input. So as it sits stock, it also shares the 5th pin common ground.
