Phantom power is
designed for an external power supply through the
mic-cable to the microphone that produces a signal
that can be considerably lower in level, hence the
need for an external pre amplifier. A professional
mic outputs its signal via three-pin XLR connector.
Simply, the phantom signal 48V DC is piggybacked on
top of both AC signals on pin-2 and pin-3 via two
resistors, without disturbance. The negative or
"return path" to the DC supply is connected to
pin-1.
A female XLR as mic input and a male XLR to feed the
mic signal to the preamp with a suitable 48V DC
power supply to make the positive and negative
connections.
Applying phantom powered units doesn't require the
presence of the internal battery and can be supplied
by stable external phantom power.
