Condenser Microphones

The most important information to know regarding condenser microphones is that they are all powered by voltage.  In order for a Condenser microphone to properly work, +48v must be added. aAlso known as “Phantom Power.” They use an electrostatic capsule meaning there are two plates involved. The back plate of the mic retains a negative charge and the diaphragm (front) retains a positive charge.

Condenser mics are more sensitive than the Dynamic microphone but are less sensitive than the Ribbon microphone. They respond very well with acoustic instruments, drum overheads, and vocals. Their sound has been described as warm, full, and bright.


Dynamic Microphone

Unlike Condenser microphones, Dynamic mics use the principle of electromagnetic induction. They are powered by an electric signal.  The mic contains a thick diaphragm that is wrapped in a coil of wire. Changes in sound pressure cause the coil to vibrate. 

Dynamic mics are the most used and can tolerate high sound pressure levels and are also extremely durable and reliable. They are great for harsh environments, live sound, and studio environments.   They are mainly used to record kick drums, snares, guitar amps, and bass amps. They are capable of withstanding loud sound sources.

Ribbon Microphones

Ribbon microphones reproduce signals very similar to condenser mics. They are built with a dynamic design and use an electromagnetic induction. A corrugated metal ribbon is suspended due to the magnetic field between two magnets, which causes it to be fragile. Vibrations are caused by acoustic pressure from the front and back.

Ribbon mics are said to pick up smooth and warm sounds. These mics are mainly used for guitar amps, strings, drum room mics, & loud rock music.
