Introduction
The PRS-1AIP1 IP Audio Interface is a universal,
Internet Protocol based audio device supporting VoIP
and Audio over IP applications. It is used for bridging
audio and contact closures over long distance LAN and
WAN networks. It extends and interfaces to e.g.
Praesideo and non network based traditional public
address systems, like Plena, without the need for a PC
during operation.
The device has analog audio line inputs and line outputs
for easy interfacing, it has optional pilot tone
supervision and generation for emergency sound
purposes. One audio input can be switched to
microphone sensitivity with built-in microphone
supervision.
Control inputs and outputs can be used to set up an
audio connection to start a remote call, but also to pass
remote fault events to e.g. a system controller.
Also, the control inputs offer cable and connection
supervision, and can activate (remote) control outputs.
