TRETTER Store Munich

About This Project

In 2025, the public address and voice evacuation system at TRETTER’s flagship store in central Munich was completely upgraded. The existing, outdated installation was replaced with an EN 54-16 certified ONE system, ensuring compliance with fire protection regulations and enhancing the safety of both customers and staff.

Located on Neuhauser Strasse in Munich’s pedestrian zone, TRETTER’s main building is the largest footwear store in Bavaria. With four floors dedicated to fashion and accessories and a high daily footfall, the building requires a reliable voice evacuation system capable of delivering clear messages in any situation.

The project, carried out by Phoenix Professional Audio in collaboration with our partner Gräf & Meyer, included dismantling the old system and implementing a new public address and voice evacuation system based on two LDA ONE units with dual EN 54-16 and EN 54-4 certification.

The main advantage of this configuration is its fast and easy integration in commercial spaces like this, as each system combines Class D amplification, battery management, and a digital audio matrix in an ultra-compact format.

This setup provides:

• 6 independent zone outputs (100V)
• 6×6 digital matrix for flexible source management
• 3 priority audio inputs with noise-gate function
• Emergency message player (dual message player)
• Integrated power and battery management

The system is complemented by ONE-LOOP expansion modules, ONE-BC1 licence cards, and TFL-2 terminators for precise monitoring of speaker lines.

An MPS-8Z microphone station, extended with an additional keypad, and a VAP-1 emergency panel were also installed. This configuration allows manual message activation, zone selection, and full control of evacuation functions.

Before commissioning, impedance, power, and earth-fault measurements were performed on the existing lines, ensuring compatibility and optimal system performance.

In high-traffic retail environments, message intelligibility and rapid response make all the difference. The ONE system delivers clear automatic and manual alerts, effective evacuation coordination, and regulatory compliance.
