Adapter for announcements over the ICT system
Ideal for waiting rooms, supermarkets and shopping centres
Acoustic announcement warnings possible
Almost any ICT system can easily be connected to loudspeaker systems
Operation and supply via an analogue extension connection of an ICT system
With the a/b Audiobox, loudspeaker systems can quickly and easily be coupled to almost any ICT system. To do this, the box is simply switched between an analogue extension on an ICT system and the amplifier input for a loudspeaker system, for example. If the a/b Audiobox is called via the extension, it automatically accepts the call and connects to the announcement system. The integrated switch relay can be used to select the loudspeaker zone of the loudspeaker system. The announcement can be preceded with an acoustic warning if required.
The a/b Audiobox is suitable for amplifiers and loudspeaker systems with an NF input (300 mVeff / 600 Ω).
