A Public Address system is what amplifies sound, to permit a single user or group of users to address a larger public number of people, typically in a venue or building. PA system is widely used in hotels, hospitals, restaurants, house of worship, airports, shopping malls, schools, leisure, factories and commercial buildings. A BGM based PA system allows the user to broadcast music to all zones and can help in entertaining/addressing the public in the most effective way. Most PA/BGM systems are interfaced with fire alarm systems, which will enable the system to release warning/alert messages to the public.
PA over IP refers to PA paging and intercom systems that use an IP network instead of a centralized amplifier to distribute the audio signal to paging locations across a building, or anywhere else in the reach of the IP network. Network-attached amplifiers and intercom units are used to provide the communication function.
