Phantom Power is a method used to supply power to certain types of microphones, particularly condenser microphones. It typically provides a voltage of 48 volts through the same cable that carries the audio signal, allowing the microphone to operate without needing a separate power source. This is especially useful in professional audio settings, such as recording studios and live sound environments. The power is sent from a mixing console or an external power supply, and it is called "phantom" because it is invisible to the audio signal. This means that the microphone can receive power without affecting the sound quality, making it a convenient solution for audio professionals.
