Public address

Providing professional audio solutions to modern transportation companies is a complex undertaking. Bus stations, subway, regional railways – all demand flexible, secure, and mostly reliable solutions for delivering announcements, music, even emergency calls directed to specific areas. Nationwide, a railway network may count hundreds of stations supported by dozens of audio servers. Of course, such an architecture incorporates an array of different voice announcement systems and the sensitive priority rules system for messaging. That is a lot to cover, operate and manage. 

Such heavy-weight – often public – operators rely on seasoned systems integrators to engineer extensive audio systems that naturally meet a series of stringent requirements. Among others, interoperability with management applications is critical, as is the ability to deliver specific notifications and emergency messages in a timely and targeted manner, according to both schedule and message priority. While the many zones involved may cover a countrywide geographic area, the retained solution must enable centralized control. It should also feature monitoring and reporting capabilities that help to ensure uptime across all zones.

Cherry on the cake, utmost reliability and steady performance of these systems are paramount to seal a deal, as they involve public security and safety. Therefore, the integrator’s sturdiness in terms of technology, production, testing and quality clearances will be tested, if not scrutinized. Better rely on rock solid systems that show a spotless track record in terms of use cases implemented at a similar scale. 

Goosebumps? Not really, Digigram has paved the way for integrators with its expertise covering complex, performance critical public address systems.
