The careful acoustic design, no compromise transducers and a unique, composite cabinet, design make the HDL 20-A the preferred tool of many professionals. Perfect in live sound reinforcement and reliable installed situations. The HDL 20-A is the ideal choice when line array performance is needed and a fast and easy set up is a must. The system is powered from a 1400 Watt Peak Power 2 way digital amplifier, sound is processed from a powerful DSP. The processing includes cluster and HF projection correction and special new presets for indoor and high curving situations. The system features state of the art RCF transducers, two powerful 10” for a solid bass reproduction and a large format 3” voice coil compression driver to deliver vocal clarity and high definition with an incredible dynamic. The HDL 18-AS is the ideal flyable bass complement for the HDL 20-A array system.

Tour sound in a compact size

The HDL 20-A is a true active and high power ready to use touring system equipped with a high efficiency digital amplifier that delivers superior SPL reducing energy requirement. The integrated processing and the cabling reduction will make the set-up faster and easier and, thanks to its compact size, the truck space requirement is reduced to the minimum.

Powerful class D amplifiers

RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. HDL amplifiers deliver a ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the HDL amplifiers present SMPS power supply section to produce maximum output and minimum weight.

HIGH FREQUENCIES - The CD850 large format compression driver delivers one of the key advantages of the HDL 20-A, the 3” voice coil allows a crossover point of 800Hz and therefore almost all of the vocal range can be produced by this driver. This allows better coverage and dispersion control, and superior efficiency.
LOW FREQUENCIES - High power woofers. Very high efficient and controlled bass reproduction.
