With the 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.
With the Mobile Audio Gateway, you no longer need to look for a microphone console in critical situations that require a rapid response. All you have to do is call direct from your mobile telephone, e.g. to a pre-set telephone number and simply start talking after you hear the gong. Thanks to the built-in relay, you can also give this mobile announcement top priority.
Naturally, there is a back-up in form of a battery, in the event of a power failure, and you can select authorised numbers from which announcements can be made. You will undoubtedly also appreciate the significant cost savings on individual announcements. By selecting an appropriate tariff on the SIM card inserted in the 2N® Mobile Audio Gateway GSM system, you can make announcements free of charge.
