Audio-over-IP interface

The PRS‑1AIP1 is a universal, IP‑based audio device
supporting VoIP and Audio over IP applications. It is an
ideal solution for bridging audio and contact closures
over long distance LAN and WAN networks, e.g. in
shopping malls, tunnels, in and between railway
stations. It extends and interfaces to Praesideo and
non‑network based traditional public address systems
without the need for a PC during operation.
The unit has analog audio inputs and outputs for easy
interfacing with optional pilot‑tone supervision for
emergency sound purposes. One audio input can be
switched to microphone sensitivity with built‑in
microphone supervision. Also, the control inputs offer
cable and connection 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 the system controller.
