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.
