I've changed my entire review to try to clarify some things about microphones and "phantom" power.  "Phantom Power" is a term that describes a power source required for "Condenser" type microphones.  It is usually 48V @ 7mA which is active on the cable that connects the microphone to the amplifier.  I suspect it is called "Phantom" power, because there is no indication that it is there, except that a condenser microphone won't work without it.  Sometimes, a condenser microphone will have its own power source, usually a battery, to provide the electrical power for the microphone circuitry.
