In SAS, we have several types of microphones, which are listed below. These microphones are a variety of types and have a variety of pickup patterns.
The theaters at SAS own dynamic microphones, condensers, and electret-condensers. They all work differently.
Dynamic Microphone: The sound hits the diaphragm. The coil inside the microphone begins the vibrate slightly. A magnet surrounds this coil (but is not attached to it). An electric charge builds up in between the coil and the magnet. This charge is carried out by a wire running through the microphone.
Condenser Microphone: The sound hits the diaphragm. A phantom power of +48 volts runs to an electrode inside the microphone. An electric field builds up in the space between the diaphragm and the electrode. This electric charge is carried out by a wire running through the microphone.
Electret-Condenser or Radio Microphone: This is a condenser microphone attached to a transmitter. The transmitter sends the electric charge to a receiver through a radio signal. The receiver then sends charge to the mixing desk or another designated place.
There is also great variety in the pickup patterns of each microphone. There are 5 basic pickup patterns microphones in SAS use.
