audioRTBUS intercom units

Low-cost Intercom. For Distributed Communication Systems

The audioRTBUS intercom units of voice INTER connect are equipped with a hands-free functionality in full-duplex quality. The audioRTBUS allows bus communication between two or more end stations over high distances (up to 1000 m) or synchronous sound playback from one source node to all target nodes.
The conditions for setting up communication links between two or more stations can be flexibly configured. Thanks to the central power supply via audioRTBUS, the compact size and versatile audio and data interfaces, the audioRTBUS stations are suitable for a wide range of applications.
