Note:
In general, phantom voltages are used to power electronics within
condenser microphones. Condenser microphones require power for
various parts of their operation, including impedance converters,
preamplifier circuitry and, in some cases, to polarized microphone
capsules. Phantom is usually a DC voltage ranging from 12 to 48
volts. Microphones draw current from this voltage based on their
needs.
