The historic Rosenheim Town Hall, a former railway building and regular filming location for the TV series Die Rosenheim-Cops<\/em>, runs on an EN 54-16 public address and voice evacuation system made by LDA Audio Tech. The installation combines four ONE-500 controllers in a ring configuration with a renewed speaker network to deliver clear announcements throughout the building.<\/p>\n

From railway station to town hall<\/strong><\/h4>\n

The building that now houses Rosenheim’s town hall (Bavaria) started out in 1858 as a railway station, designed by architect Eduard R\u00fcber. It passed into municipal hands in 1878 and has served as the seat of local government ever since.<\/p>\n

Its facade has become known well beyond Rosenheim thanks to the German TV series Die Rosenheim-Cops<\/em>, where it doubles as a police station. As an active administrative building and tourist landmark, it receives public employees and visitors every day. That makes a public address and voice evacuation system essential, one that can handle everyday announcements and, in an emergency, deliver clear evacuation instructions in line with EN 54-16.<\/p>\n

Public address and voice evacuation with the ONE system<\/strong><\/h4>\n

The upgrade, carried out by Phoenix Professional Audio<\/a> together with our partner Gr\u00e4f & Meyer<\/a>, replaced the old public address setup and brought the building’s entire speaker network up to date.<\/p>\n

At the core of the installation are four ONE-500 units<\/a> linked in a ring through the ONE-LOOP module<\/a>, certified to EN 54-16 and EN 54-4. Each controller packs class D amplification, emergency management and backup power into a single 2U chassis, with six independent audio outputs and three noise-suppressed inputs that keep voice intelligibility consistent.<\/p>\n

The system is operated from an MPS-8Z microphone desk<\/a> with an MPS-8K keypad extension, letting staff select zones and launch announcements from a single control point. The result is a century-old town hall with a public address and voice evacuation system built for its current needs, without losing its historic character.<\/p>\n
