If you're talking about noise from the phantom power source in the
recorder, it will be applied equally (depending on the accuracy of
the series resistors) to pins 2 and 3, assuming equal impedance
(which is why the dummy network on pin 3 of the mic) and will be
canceled by the balance of the mic preamp.
