What is phantom power used for in audio equipment?

Phantom power is a technology used in audio equipment specifically to provide 48V power to certain types of microphones, commonly condenser microphones. These microphones require external power to operate because they rely on an internal preamplifier to amplify the audio signal. When phantom power is supplied through the same cables used for audio signal transmission, it allows for a cleaner and more robust signal. This is essential in professional audio settings where quality and reliability of sound capture are paramount. Other options, while they relate to audio performance and signal quality, do not accurately describe the role of phantom power in audio equipment.
