RCF’s D-Line has grown with the addition of the large format HDL50-A. The most powerful in the series, the HDL50-A is an active three-way line array module, designed specifically for large events — both indoors and outdoors.
Equipped with two 12” woofers, four symmetrical 6.5″ mid-ranges and two 2” drivers, it includes a built in 4400-watt powerful digital amplifier and uses neodymium magnets and a new housing constructed from lightweight plywood and polypropylene (and a weight of only 106 pounds).
The custom 4PATH designed waveguide allows a precise coverage of 90°x10° degrees and the unique shape of the four ducts forming the guide create an ideal isophasic load from 700 Hz to the highest audible frequencies.
The two ND850 large format compression drivers deliver one of the key advantages of the HDL 50-A, while the 3” voice coil allows a crossover point of 800Hz allowing this driver to produce almost all of the vocal range. RSF says this allows better coverage and superior efficiency. And, the symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL50-A take care of the constant directivity without spots of break up or attenuation. The originally designed V-SHAPED front baffle provides co-planar mid-ranges and woofers and a controlled LF dispersion.
A 4400-watt peak power digital amplifier powers the HDL50-A: 800 watts for the HF, 1400 watts for midrange section and 2200 watts for the LF. New generation DSP handles all the processing within the cabinet and allows adjustment of Cluster size and HF projection.
All these settings are accessed by the encoder on the rear of the cabinets or using the integrated RDNet remote control. The controls on the back of the speaker allow a number of simple optimizations to be carried out at the flick of a switch.
The HDL50-A tour grade system comes in a composite wooden polypropylene enclosure, and is equipped with two aluminum side handles with rubber handgrips and two rear handles for portability.
