Join Bill Gibson for an in-depth discussion in this video Condenser operating principle, part of Microphone Techniques: Essentials.
- [Instructor] Unlike the magnetic capsule … used by dynamic microphones, … condenser microphones work on a purely electrical level … where the wave form sympathetically vibrates … a thin piece of mylar that's been lightly coated … with a conductive alloy, … a gold alloy in some cases. … A condenser uses phantom power to apply a polarized voltage … to the thinly coated mylar diaphragm … that's directly adjacent to a solid conductive plate. … The electrical charge builds up … and is stored between the fixed and moveable plates. … The area between the two plates becomes a capacitor … which is something that holds an electrical charge. … In fact, the old school name for capacitor is condenser. … As the sound wave hits this thinly coated mylar diaphragm … the vibration varies the stored electrical charge. … And the variations in this area of charged air, … called the dielectric, are the source of the signal … that's sent from the microphone to the mixer. … If we compare the amount of energy …
