Brooks XM 204 reviews Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.
Chamber
1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console).
2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber.

4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.
