The NDA-200 A is a compact 2-channel amplifier module from the VARES-1500 series, specifically designed as a retrofit kit for the NVC series. Delivering 2x 100 W output power, it is ideal for small to medium-sized audio zones, especially in voice alarm and public address systems.

Designed for space-efficient installation, the module fits seamlessly into existing NVC-series enclosures. Fully compatible with the VARES-1500 system architecture, the NDA-200 A is ready for immediate integration and supports all relevant signal processing and monitoring functions.

With two independently controlled audio output channels, the amplifier allows flexible zone configuration. Output is provided at 100 V constant voltage, making it suitable for longer speaker lines in commercial and industrial environments.

The NDA-200 A is the perfect choice for expanding existing systems or retrofitting older installations with modern amplifier technology—without replacing the entire system infrastructure.
