3. THE HDL 50-A 4K SYSTEM

The HDL 50-A 4K is a true active high power ready to use touring system for large events, indoors and outdoors.

Equipped with 2x12” woofers, four symmetrical 6.5” midranges and two 2” drivers, it offers excellent playback quality

and high sound pressure levels with a built in 4000W RMS powerful digital ampliﬁer that delivers superior SPL, while

reducing energy requirement.

Each component, from the power supply to the input board with DSP, to the output stages to woofers and drivers, has

been consistently and specially developed by RCF’s experienced engineering teams for the realization of the HDL 50-A

4K system, with all components carefully matched to each other.

This complete integration of all components allows not only superior performance and maximum operational reliability,

but also provides users easy handling and plug & play comfort.

Besides this important fact, active speakers offer valuable advantages: while passive speakers often need long cable

runs, the energy loss due to the cable resistance is a huge factor. This effect is not seen in powered speakers where the

ampliﬁer is just a couple of centimeters away from the transducer.

Using advanced neodymium magnets and a groundbreaking new housing constructed from lightweight plywood and

polypropylene, it has a remarkably low weight for easy handling and ﬂying.
