RCF HDL 50-A 4K

The HDL 50-A 4K is an active 3-way line array module designed for large-scale events, both indoor and outdoor. It features eight best-in-class drivers, delivering exceptional sound quality ideal for professional music applications. The patented 4PATH waveguide (90° x 10°) combined with the symmetrical arrangement of drivers for each frequency band provides optimal coverage. The integrated 4-channel Class D amplifier produces a clean signal with a peak power of up to 8000 W Peak (4000 RMS). The speaker's volume level reaches up to 143 dB.

The power section of the HDL 50-A 4K is tailored to the drivers and cabinet construction to achieve outstanding efficiency, low distortion, and high signal-to-noise ratio. The amplifier module features a sturdy aluminum construction that stabilizes the amplifier during transport. Operating at very low impedance, the amplifier delivers fast and detailed transient response, while a high damping factor enhances sound quality and detail. The input signal preamplifier is equipped with dual opto-isolation to prevent noise and ground loops.

On the rear panel of the speaker, you can adjust volume, bypass, delay, presets, and advanced functions. All settings can be controlled via the encoder on the rear panel or using the RCF proprietary RDNet network protocol, allowing management and control of professional mobile sound systems and complex installations. RDNet provides intuitive control and monitoring of each connected device/object in the RCF audio system, including built-in tilt measurement and speaker performance. Each device has DSP, and specific presets or parameter adjustments can be addressed for individual objects or groups of objects. Network users can adjust levels, delay, equalization (including FiR filters), and other settings, including advanced subwoofer configurations in the system.

The HDL system gives you the flexibility to work in many different locations with the same system, only needing to adjust the number of modules to achieve optimal performance and coverage. The system can be quickly installed, and once suspended, the proprietary software minimizes the time required for overall setup. Up to 20 HDL 50-A 4K modules can be suspended below each other.
