The power necessary to run these circuits may come from a small battery in the microphone or from another external device (such as the mixer or the recorder). This is called phantom power and is a ...

Two techniques “Phantom powering” is the most common way to power a microphone. The technique supplies 48 V provided through two 6.81-kΩ resistors in a differential input line. 1 This idea ...

Usually, the phantom power supply isn't required by any devices further down the signal chain. The microphone preamplifier is usually running from lower value split voltage supplies (±5V —> ±15V).
