2N® Mobile Audio Gateway

Public Announcements from Anywhere in the World

With the 2N® Mobile Audio Gateway you have the opportunity to make live announcements, simply and easily, from any telephone (including mobile phones), even in places where there is no landline. All you need is GSM coverage or a 3G signal. You can thus use this intelligent audio system to make immediate live announcements, in particular at chain stores, in large production halls and complexes or local PA systems.

Product highlights:

The whole 2N® Mobile Audio Gateway public address system works on the plug&play principle, so there’s no complicated set-up. All you have to do is connect to an existing PA or evacuation exchange and you can start making announcements immediately from anywhere in the world.
