Advanced Public Address Server

The PRA-APAS is an industrial PC with pre?installed software, acting as a server for PRAESENSA. It provides advanced business related public address functions without compromises and does therefore not support emergency functionalities. The PRA-APAS supports connections to two separate local area networks, the PRAESENSA secure network and the public network with access to the Internet, with a firewall in between. On the public network it connects to the Internet and to one or more licensed operator devices, such as a wireless tablet or a regular PC. On the secure PRAESENSA network it interfaces with the system controller for control and transfer of multiple simultaneous audio channels. The operator devices use their own web browser to control background music, streaming from PRA-APAS’ own internal memory or from external music portals and Internet radio stations. It offers announcement creation and control facilities to the operator, including message scheduling, live call recording with pre?monitoring and playback, and even multi?lingual text?to?speech calls, using on?line conversion services.
