The ribbon elements in some vintage ribbon microphones can be harmed or even destroyed by the presence of phantom power. For this reason, it is commonly recommended that phantom power be turned off when using ribbon microphones. ... They require phantom power to operate and obviously will not be damaged by phantom power.

Do all ribbon microphones require 48v phantom power?

Active ribbon mics only require phantom power for their active circuitry. If the phantom power DC voltage reached the ribbon diaphragm, it would most likely cause irreversible damage. So although active ribbon mics require phantom, no ribbon diaphragm should ever be subjected to phantom power!

Does my mic need phantom power?

Put simply, condenser microphones have active electronics that need an external power source, while dynamic mics are passive and therefore do not need phantom power. Because of the way condenser mics work, their output is very high impedance, and therefore requires a powered circuit to reduce that impedance. 3.
