Public Announcement System

A public address system is an electronic sound amplification and distribution system, used to allow a person to speak to a large public, for example for announcements of movements at large and noisy air and rail terminals or at a sports stadium or amplify other audio content, such as recorded music or the live sound of a band.

 

Now a days, 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 campus, or anywhere else in the reach of the IP network (including the Internet).

 

We at Microtel Netlinks Design Network based PA system which includes Network enable amplifiers and intercom units to provide the communication function. At the transmission end, a Microphone / Media Player transmits a digital audio stream via the local area network. At the receiving end, either specialized IP speakers receive these network transmissions and reproduce the analog audio signal. These are network appliances addressable by an IP address.
