RCF HDL 50-A 4K Active Three-Way Line Array Module

The HDL 50-A 4K is RCF’s most powerful active line array module to date, delivering 8000 watts of peak power with exceptional audio clarity and projection. Engineered for large venues and outdoor events, it features a 3-way configuration with two 12″ woofers, four 6″ midrange drivers, and two 3″ compression drivers, all equipped with neodymium magnets for reduced weight and high performance. The integrated 4-channel Class D amplifier is housed in a robust aluminum structure, providing thermal stability without a fan. With built-in RDNet networking, advanced DSP control, FiRPHASE filtering, and a symmetrical V-shaped cabinet design, this system ensures uniform sound distribution and easy deployment. Fast rigging mechanisms and lightweight materials further streamline setup, making the HDL 50-A 4K a premium choice for touring and fixed installations.
