POE IP public address system

POE IP public address system - A public address system is one that allows a single user or group of users to address a larger public number of people with the use of a microphone (or other audio source), a mixer, amplifier and loudspeakers typically in a venue or building.
The components of a public address system are different depending upon the size and type of venue or building and the number of people a system needs to address. A Background Music System in a commercial environment is a music playback system that plays continuous background music, normally via a distributed public address audio system. It may include an element of zoning so volume levels are suitable for each area or zone of an environment. The music selection for a commercial background music system may also be profiled for a particular brand; venue or building so music that plays is suitable and automatically updated for the venue.
