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 20-A is powered by a 1400W peak power digital amplifier, split 200W for the HF and 500W for the LF. A new generation DSP handles all the processing within the cabinet and allows adjustment of Cluster size and HF projection. The DSP also includes presets for indoor/outdoor usage and highly curved arrays. All these setting are accessed by the buttons on the rear of the cabinets.

The easy to access controls on the back of the speaker allow a number of simple optimisations to be carried out at the flick of a switch: two possible HF settings, four possible cluster configurations; a special EQ setting for high curved configurations and an Indoor Correction EQ.

In order to assist with the set up procedures for the HDL 20-A line array system, RCF has developed a complete prediction software package. The software enables a complete two dimensional simulation of the behaviour of the HDL 20-A modules and also suggest the correct subwoofer combination.

The system curvature angles and the sound projection data are computed with maximum sound pressure levels for the given design. The software will allow simulations up to a maximum of sixteen HDL 20-A systems. The rigging menu provides data for weight, centre of gravity and length of the array configuration. Rigging points and rigging hardware configurations are also computed.
