THE HDL 6-A
THE HDL 12-AS
The HDL 6-A is a true active high power ready to use touring system for small to medium size events, indoors and 
outdoors. Equipped with 2 x 6” woofers, and a 1.7” drivers, it offers excellent playback quality and high sound pressure 
levels with a built in 1400W 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, 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.
The HDL 6-A is the ideal choice when line array performance is needed and a fast and easy set-up a must. The system 
features state-of-the-art RCF transducers; the high-powered 1.7” voice coil compression driver mounted on a precise 
100° x 10° waveguide delivers vocal clarity with high definition and an incredible dynamic.
The HDL 12-AS is the companion subwoofer for HDL 6-A. Housing a 12” woofer, the HDL 12-AS, is a very compact 
active sub enclosure and features a 1400 W powerful digital amplifier. It is the ideal complement to create flown HDL 
6-A clusters with outstanding performance. Thanks to its compact size it can easily be carried and is very quick and easy 
to start using the built-in digital stereo crossover (DSP) with adjustable crossover frequency to connect the line array 
module.
It features a built-in digital stereo crossover (DSP) with adjustable crossover frequency to connect the HDL 6-A line array 
module or a satellite. 
The integrated mechanics are both fast and reliable. The heavy-duty front grille is power coated. A special transparent-to-
sound foam backing inside helps the further protection of the transducers from dust.
POWER REQUIREMENTS AND SET-UP 
WARNING
• The system is designed to operate in hostile and demanding situations. Nevertheless it is important to take extremely 
care of the AC power supply and set up a proper power distribution.
• The system is designed to be GROUNDED. Always use a grounded connection. 
• PowerCon appliance coupler is a AC mains power disconnection device and must be readily accessible during and after 
the installation. 
CURRENT 
The following are the long term and peak current
requirement for each HDL 6-A/HDL12-AS module:
The total current requirement is obtained multiplying the single current requirement by the number of modules. To obtain the best 
performances make sure that the total burst current requirement of the system doesn’t create a significant voltage drop on the cables. 
GROUNDING 
Make sure that all the system is properly grounded. All the grounding points shall be connected to the same ground node. 
This will improve reducing hums in the audio system.
VOLTAGE LONG TERM
230 Volt 3.15 A
115 Volt 6.3 A
