Technology

Thanks to our proprietary floating output stage, evacuation messages remain secure and intelligible even during an earth short event. By replacing traditional heavy transformers, this innovative design achieves lower weight, higher bandwidth, and uncompromised reliability (see our schematic). In dadition, the floating topology enables output offset for precise earth fault monitoring, delivering the perfect balance of safety, efficiency, and performance.

Available as either a smart add-on board or seamlessly integrated into our power supply modules, our battery charging functionality brings flexibility and reliability to your system. With EN54-4 ready design, impedance monitoring, and real-time status feedback, it ensures secure operation in critical environments. Adjustable charging profiles provide full control over duration and voltage, giving you the perfect balance of compliance, safety, and efficiency.

By integrating temperature sensing directly on the drain of the power transistor, our design ensures precise monitoring and robust thermal protection at the very source. Coupled with heat dissipation technology, this approach not only safeguards junction reliability of our essential component but also enables efficient heat evacuation. The result: highly compact, lightweight modules that combine durability with effortless system integration.

At the heart of our Class-D technology lies a proprietary closed-loop control that operates seamlessly across any load and the entire audio bandwidth, eliminating the need for damping networks. This advanced closed-loop architecture ensures consistent stability, while spread-spectrum modulation and an optimized BTL stage minimize common-mode noise. The result is high-efficiency amplification with outstanding signal integrity and best-in-class EMI performance.

Designed for worldwide integration, our switch-mode power supply operates seamlessly from 85 to 276 VAC with automatic input selection, making it instantly compatible with diverse regional mains. Coupled with a fast transient-response switching stage, it guarantees stability and responsiveness under the most demanding audio dynamics.

To meet both customer expectations and the rigorous demands of EN54 certification, our modules integrate a comprehensive set of auxiliary functions. From auxiliary voltages for external user interfaces to earth short-circuit detection and isolated supervision of backup or mains supply, these features simplify complete system design while reinforcing reliability and compliance.

On-board power limiters enable the selection of continuous output power while preserving audio fidelity, ensuring dynamic performance without compromise. Complementing this, current limiters regulate output delivery to prevent unwanted protection triggers when driving complex loads, such as monitoring elements, providing a smooth and adaptive safeguard.

Our constant current and constant voltage architectures ensure seamless adaptability across diverse audio systems. Constant voltage mode is ideal for 100 V line integration, fully compliant with EN54-16 standards, while constant current operation expands system possibilities by supporting very low impedances, making it perfectly suited for demanding applications such as induction loops or more powerfull usage.
