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.
