Features

The most powerful HDL array ever made by RCF
The 4K amplifier doubles the power of the HDL 50-A to achieve new levels of clarity and absence of distortion. Transducers work at full performance and the SPL output is more than doubled. Furthermore, we improved the power supply section with a tripled current level on fast transients, for a level of detail usually achieved only in high-end studio monitors.
Faster and more powerful
The 4K amplifier is an essential part of HDL 50-A reengineering effort. The 4000 W RMS Class-D power operates at very low impedance producing a quick and detailed transient response, while the high damping factor improves sound quality and detail. The HDL 50-A 4K power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion and high signal-to-noise ratio. The amplifier module features a solid machined aluminum structure that stabilizes the amplifier during transportation. The control panel on the back adjusts volume, bypass, delay, presets and advanced functions. The signal input preamplifier features a double opto isolation to avoid noise and ground loops.
DSP Processing
New generation DSP handles processing inside the cabinet and allows for the adjustment of Cluster size and HF projection. The low-latency 32 bits DSP section deploys a remarkable amount of processing power for live performances with straight-forward control and monitoring of individual sections of the module, including the onboard inclinometer and transducer performance via RDNet. An entire set of protections preserve product life and reliability. All settings are controllable by the encoder on the rear of the cabinets or using the integrated RDNet remote management. The easy-to-access control panel allows for simple optimizations of the module.
V-shaped symmetrical design
The symmetrical design of the cabinet produces identical left / right coverage. The component arrangement and the special DSP crossover filtering of the HDL 50-A allow for a constant directivity without spots of break up or attenuation. The V-SHAPED front baffle provides: Coplanar midranges and woofers Controlled LF dispersion Central space to host the HF guide
Neodymium RCF precision transducers
High frequencies - Two ND 840 large format compression drivers are one of the key advantages of the HDL 50-A. The 3.0” voice coil allows for a crossover point of 800 Hz. The driver itself delivers a sizable portion of vocal range with better intelligibility. Mid frequencies - 4 x 2.0” voice coil 6.0” neo midranges - Water resistant fiber doped cone - Polycotton M-roll surround - High power magnetic structure. Low frequencies - 2 X 3.0” voice coil neodymium 12” woofers - Water resistant fiber doped cone - Polycotton M-roll surround - Hypervented magnetic structure.
New perspective on linearity
RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener. The special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.
