Public Address System
Audio for meeting facilities is a topic that encompasses a wide range of applications, from a simple public address system in a courtroom to a multi-channel legislative system with recording and broadcast capabilities. Though
these systems may vary in size and complexity,
they are all governed by the same physical
principles and they share certain types of
equipment. Common components of these
systems include microphones, automatic
and non-automatic mixers, power amplifiers,
loudspeakers, and many types of electronic
signal processing devices such as equalizers,
compressors, and audio time delays. A complete
audio system may involve some or all of these
items.
