'Phantom Power' - the industry standard method of transmitting DC voltage over an audio cable to provide power to professional audio devices.
Phantom Power transmits the voltage and audio signal simultaneously over the same audio cable to the microphone or other connected audio device.
Microphones are the most common devices to use Phantom Power, but other devices such as DI boxes and pre amplifiers also often use this power supply technology.
Phantom Power will usually be supplied by the audio system's power amplifier or mixing desk or sometimes via specific Phantom Power Supply devices.
No, phantom power will not affect your audio signal atall. However it is important to ensure that you don't use a phantom power supply on a microphone which does not require it - such as dynamic microphones - to avoid any incompatibility issues.
