From the SXM2 manual -
"LEMO in L: Shield = Gnd, Pin 1 = +10V, 2 = +48V, 3 = signal in
LEMO in R: Shield = Gnd, Pin 1 = +10V, 2 = +48V, 3 = signal in
BINDER: Pin 1 = Gnd, 2 = L in, 3 = R in, 4 = +6.2V, 5= +48V
The SX-M2/LS can be used for all condenser or electret microphones having the
possibility of changing the capsules on the microphone body, such as: Colette
series of Schoeps, Blue Line of Sanken, or the similar line of Neumann.
It is important for these kind of microphones to use a good quality active cable.
When buying the cable from a microphone manufacturer, do inform them that the
amplification electronics often used in the cables is not required. "
If you are getting +48V on pin 2 that's what almost any mic that runs on phantom is looking for. I don't have an answer about the +10V on pin 1, probably the voltage for the FET in the cable.
Since the cicuitry for the microphone preamp (the body) is built in it's presenting the voltage that capsule/cable combination would be seeing after the mic body.
I guess I was just talking out my ass...not the first time. Sorry for presenting wrong info
