What is the purpose of phantom power in audio production?

The purpose of phantom power in audio production is to provide power to specific microphones and devices that require an external power source to operate, particularly condenser microphones. These types of microphones have active components that need electricity to function, and phantom power supplies this voltage through the same cable that carries the audio signal, typically through XLR connectors. This means that a single cable can handle both the audio signal and the necessary power, simplifying setup and reducing the need for additional power supplies or batteries for the microphones.

Options related to amplifying sound levels, reducing noise interference, or enabling wireless communication do not align with the specific function of phantom power, as these functions are accomplished through different means and equipment in audio production.
