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 method for transmitting DC electric power through microphone cables to operate microphones that contain active electronic circuitry.
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 Powering was used in telephone systems since the introduction of the rotary-dial telephone in 1919 before it was applied to condenser microphones.
The first known commercially available phantom-powered microphone was the Schoeps model CMT 20, which came out in 1964.
