What is Phantom Power?
A convenient way to power a condenser microphone is with phantom power from a separate device. Phantom power uses the same cable that transports the audio signal out of the mic, to transport power to the mic. If you are able to provide phantom power to a microphone, you will not need batteries.
Phantom power capabilities are often built into mixers. You’ll likely be able to access it with an on/off switch on the mixer.
While it is intended for condenser microphones, if a dynamic microphone was accidentally fed phantom power, it would not damage the microphone.
Phantom power is a DC or direct current power source available in various voltages. It is manufacturer-specific, and sometimes product-specific.
