RCF HDL 50-A 4K - 8000W 2 x 12-inch Powered 3-Way Line Array Loudspeaker with 90 x 10-Degree Coverage in Black Finish

The RCF HDL 50-A 4K is a powerful and compact 3-way active line array system designed for large-scale events, both indoors and outdoors. Engineered to deliver exceptional sound pressure levels and high-definition audio, this system is equipped with a remarkable 8000W peak, 4000W RMS Class-D amplifier that provides unmatched clarity and low distortion. Capable of producing up to 143 dB SPL, the HDL 50-A 4K is an ideal solution for professional sound reinforcement in demanding environments. Its advanced transducer configuration includes two 12-inch neodymium woofers, four 6-inch midrange drivers, and two 3-inch titanium dome compression drivers, all designed to work seamlessly together for optimal performance.

The HDL 50-A 4K features RCF's proprietary 4PATH waveguide, providing precise coverage of 90 x 10 degrees. This custom waveguide design ensures a superb, linear high-frequency response and excellent sound distribution, eliminating issues such as break-up or attenuation commonly found in less advanced systems. The symmetrical design of the cabinet further enhances the coverage uniformity, delivering an identical left and right sound output. The system's integration of RCF's FiRPHASE technology ensures transparent sound, perfect imaging, and minimal phase distortion, resulting in a high-quality listening experience across a wide range of applications.

The heart of the HDL 50-A 4K is its 4-channel amplifier, which doubles the power output of the previous models, allowing the system to operate at high levels of performance without distortion. The amplifier's low impedance operation produces an ultra-fast attack and detailed transient response, while the high damping factor ensures sound quality and clarity. Additionally, the amplifier features an aluminum housing that aids in efficient heat dissipation, ensuring the system remains reliable and efficient during extended use. A specially designed preamplifier with double opto isolation protects against noise and ground loops, enhancing overall system performance.

For system integration and remote control, the HDL 50-A 4K is fully compatible with RDNet, RCF's robust network management platform. RDNet allows for intuitive control and monitoring of every device in the RCF audio system, including level adjustments, delay settings, EQ modifications, and advanced subwoofer configurations. With RDNet, users can make adjustments to single devices or groups of connected systems, making it an ideal solution for large-scale installations and live performances. RDNet also provides remote monitoring of individual sections of the module, including transducer performance and rigging angles, ensuring that the system performs optimally throughout an event.

The HDL 50-A 4K is built for durability and ease of use. It features an advanced rigging system that allows for quick and secure setup, including the ability to create J-shaped and spiral arrays. The system can be rigged with up to 20 modules on a single flybar, and the angle of the array can be adjusted before it is hung. Once in position, the system automatically locks into place, ensuring quick and reliable deployment. The heavy-duty powder-coated steel grille and transparent-to-sound foam backing protect the transducers from dust and environmental damage, and the system is available with an optional rain cover for outdoor use.

Whether used for live events, installations, or touring applications, the RCF HDL 50-A 4K delivers the power, clarity, and flexibility needed for the most demanding sound reinforcement scenarios. With its advanced amplifier technology, precision waveguide, and RDNet integration, it sets a new standard for large-scale audio systems.
