The capacitive capsule in the majority of capacitor microphones stores a static charge in order to function. The conventional method of creating static charge is known as a DC-Bias and involves introducing an external DC voltage. The voltage is typically approximately 60VDC, however higher voltages allow for additional headroom and can also change the capsule's sensitivity, which is helpful for setting multi-pattern microphones. The electret design, in which the static charge is given by a dielectric substance integrated into the mic itself, is the most popular DC-Bias substitute. The RF-bias approach, which operates on an entirely different concept, offers a third option.
