Product information for RCS Audio-Systems NDA-1000 A:

The NDA-1000 A is a high-performance, network-capable digital power amplifier with integrated emergency power supply, certified according to EN 54-16 and EN 54-4. Engineered for professional voice alarm systems (VAS), it ensures robust and reliable audio amplification, even during emergency operation.

With its fully digital system architecture, the NDA-1000 A offers outstanding efficiency and audio clarity. It features two independent output channels delivering 500 W RMS each at 100 V – ideal for large-scale voice evacuation and announcement systems. The unit includes three redundant power supplies to guarantee maximum operational reliability.

An integrated battery charger with temperature sensor and EN 54-4 compliance enables operation with shared battery packs across multiple amplifiers. Additionally, the unit provides a 24 V DC auxiliary output for powering external components.

The amplifier monitors mains power faults, battery status (including internal resistance checks), and all audio output channels. Via AMP-Link protocol, it seamlessly integrates with the VARES-2000 system for full remote control and diagnostics.
