IP Audio Interface

Combine the Strengths of the IP and the Analogue Audio World
Plug & Receive: Based on open standards, the IP-A1AF Audio Interface plugs right into standard IP networks and can be easily integrated into your video management system (VMS) or SIP-based communication system. A single standard network cable provides both power and connectivity with your network.
The IP-A1AF IP Audio Interface can integrate analogue receiving devices into your network as e.g., conventional low impedance speakers or local PA systems. A wide variety of low impedance speakers like TOA's F-series can therefore be turned into IP speakers. Furthermore, PA or BGM systems without SIP or ONVIF* interface can now be integrated into your network solutions.

Flexible Group Paging: The IP Audio Interface can also be addressed via multicast, enabling audio paging into groups or larger zones of IP audio devices simultaneously.

Application Examples:
Event rooms with high power analogue PA systems can be integrated into VMS or SIP telephone systems. Retail chains with existing local PA/BGM systems can be integrated into IP solutions providing network control and centralized management opportunities.
