Ideal for mid-to-large application areas

As a pioneer in the public address industry, Bosch understands that operator comfort and peace of mind is paramount. You need a PAVA system that you understand, that understands how you work and what you need to do your job. That’s why Bosch created the IP-based PRAESENSA public address and voice alarm system with an interface that keeps you in charge and helps you at every step. First, a user-friendly design lets you know what’s going on, audio or voice messaging, in every area. Need to adjust the volume and music selection per area? No problem. And when you need to make an announcement, the system will guide you through, and let you know when the voice announcement has been made successfully. Other users, such as emergency and safety personnel, have their own access to the PA system, which will adjust to meet their requirements, giving you one less thing to worry about.
