well, for sure  no, as (I think Klas implies)

The 48v Phantom idea is Earth/Ground/ pin 1 of an XLR = 0v [in DC powering 
Pins 2&3 of an XLR are BOTH at +48v DC relitive to that (this is the whole 
idea of this voltage being "Phantom" there is (ideallaly) NO DC votage 
difference between the the 2 main audio wires. (2&3 of an XLR)
