RCF HDL 50-A 4K 4,000W 3-Way Line Array Speaker – Black

RCF HDL 50-A 4K active three-way line array module

The RCF HDL 50-A 4K active three-way line array module is engineered for large-scale sound reinforcement in demanding indoor and outdoor environments. Designed with an advanced three-way configuration, it integrates eight high-performance neodymium transducers, delivering exceptional clarity, power, and coverage for professional live sound applications. The system achieves a maximum sound pressure level of 143 dB, supported by a powerful 8000W peak, 4000W RMS Class-D four-channel amplifier, ensuring high output with low distortion and excellent transient response.

The proprietary 4PATH waveguide with a 90° x 10° dispersion pattern ensures precise and consistent sound coverage, while the symmetrical V-shaped cabinet design enhances directivity and eliminates acoustic inconsistencies. The integrated DSP operates at 48 kHz and 32-bit resolution, allowing advanced processing, system tuning, and real-time monitoring through RDNet network control. This enables engineers to manage multiple modules efficiently in complex array configurations.

The amplifier section is optimized for high efficiency and superior signal-to-noise ratio, featuring improved power delivery for fast transient response and detailed audio reproduction. Built with durable Baltic birch plywood and reinforced with polypropylene side panels, the enclosure ensures reliability in touring and installation environments. Integrated rigging hardware allows flexible array configurations with precise angle adjustments, supporting up to 20 modules in a single array. The HDL 50-A 4K offers a combination of power, precision, and intelligent control for professional audio systems.
