CMX DU-50 PA Driver Unit with 100V Line Transformer

Public address systems often suffer from poor voice intelligibility over long distances, especially in noisy outdoor environments or spacious indoor facilities. The CMX DU-50 PA Driver Unit solves this by delivering high sound pressure levels and clear vocal projection across commercial speaker lines.

Equipped with a built-in 100V line transformer and standard horn threading, this driver integrates seamlessly into multi-speaker commercial audio configurations without signal loss over extensive wiring runs.

CMX DU-50 Key Features

• 50W Rated Power: Produces high-output audio necessary for outdoor announcements and open-air coverage.

• Built-in 100V Line Transformer: Allows daisy-chaining multiple speakers over long cable runs with minimal power loss.

• Standard Thread Mounting: Pairs easily with universal reflex horn flares for directed acoustic throw.

• Weather-Resistant Enclosure: Protects internal voice coil elements against dust and harsh operating conditions.

• Optimized Vocal Range: Tuned specifically for speech reproduction, ensuring messages remain clear in noisy areas.

Why Choose This Horn Driver Unit

Unlike standard low-impedance drivers that require thick, expensive cabling and short runs, the CMX DU-50 utilizes a 70V/100V line matching transformer. This makes it far more practical for large-scale industrial setups, school campuses, and religious institutions where speakers are spread hundreds of meters apart.

However, keep in mind that this is a public address compression driver tuned primarily for mid-range speech clarity. It is not engineered for full-range musical fidelity or deep bass response, making it suitable strictly for voice projection and signaling horns.

CMX DU-50 Best Use Cases

• Mosque minarets and religious congregation halls.

• School grounds, colleges, and sports arenas.

• Industrial warehouses, factories, and parking facilities.

• Railway platforms and bus terminals for routine announcements.
