BOSCH PRS-1AIP1 IP Audio Interface (used for SIP phone paging) - with North America Powercord

The PRS 1AIP1 IP Audio Interface is a professionally designed universal, Internet Protocol based audio device that is capable of supporting VoIP and Audio over IP applications. It is used for bridging audio and contact closures over long distance LAN and WAN networks. It is extending and interfacing to e.g. Praesideo and non network based traditional public address systems, like Plena, without needing for a PC during operation.

The device comes with a analog audio line inputs and line outputs intended for easy interfacing, it comes along with optional pilot tone supervision and generation for emergency sound purposes. One audio input is capable to be switched to microphone sensitivity that comes along with built in microphone supervision.

Control inputs and outputs are capable to be used for setting up an audio connection to start a remote call, but also for passing remote fault events to e.g. a system controller. Also, the control inputs are made for offering cable and connection supervision, and possible to activate (remote) control outputs.

Features

• Digital audio transmission between public address systems on remote locations
• Designed to comply to international standards for emergency sound systems
• Supervised control inputs and control outputs
• A single unit can act as transmitter, receiver or both
• Installation and configuration via standard web browser
• Support for re-broadcasting to extend the system size
• Built-in configurable audio delay
