Advance 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.
