Description

TOA VX-050DA 500W Digital Power Amplifier Module – EN54-16 Certified High-Power Amplifier

The VX-050DA is a single-channel, high-efficiency Class-D digital power amplifier. Fully certified to EN 54-16, it is designed to handle the most demanding speaker loads within a VX-3000 frame (VX-3004F, VX-3008F, or VX-3016F). Despite its massive output, it shares the same compact, modular footprint as the lower-wattage models.The TOA VX-050DA is a high-efficiency 500W digital power amplifier module engineered exclusively as a core high-power component for the TOA VX-3000 integrated voice evacuation system. Fully certified to the strict EN 54-16 European standard for fire alarm and life-safety systems, this single-channel module ensures ultimate broadcast reliability during critical mass notifications, emergency warnings, and high-output public address applications.

Utilizing advanced Class-D amplification technology, the VX-050DA delivers massive acoustic performance while maintaining a lightweight, transformerless design that generates minimal heat. It operates on a 31V DC power source and offers selectable multi-voltage outputs across 50V, 70V, and 100V lines to match your specific high-power speaker infrastructure. To optimize energy efficiency, the module integrates an intelligent eco-friendly standby mode that slashes idle power consumption to a mere 1.4W during non-emergency periods.

Designed for seamless modular integration, the unit slides effortlessly into the VX-3004F, VX-3008F, or VX-3016F voice evacuation frames via a single control link, eliminating complex audio wiring. Maintenance is simplified through a rear-accessible fuse and an integrated front dust filter that can be cleaned without removing the unit. Choose the TOA VX-050DA to guarantee rock-solid, high-power amplification for your facility's safety layout.
