BLACK  &  WHITE 

When in need of a particular appearance, matching the colour of interiors, or searching for a stylish, minimalistic sound system for your next DJ set, we can provide you with a full set of white speakers — a tough coating for wooden speakers or a robust white polypropylene composite material for portable systems, pole included, in perfect fashion. Purity and elegance, all available to be included in corporate gigs, weddings, and houses of worship.

RCF RDNet

NETWORKED CONTROL AND MUCH MORE RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.

THE ACOUSTIC BEAUTY OF THE SYMMETRY

The symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL 28-A take care of the constant directivity without spots of break up or attenuation. The specially-designed front baffle provides coplanar woofers, controlled LF dispersion and a central space to host the 4PATH waveguide. The heavy-duty front grille is powder coated. A special transparent-to-sound foam backing inside helps to further protect the transducers from dust. For weatherproof capabilities, a rain cover is available.

POWERFUL CLASS D AMPLIFIER

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.

FIRST CLASS TRANSDUCERS

The RCF HDL 28-A features state-of-the-art RCF transducers with neodymium magnets. RCF’s experienced engineering teams have specially developed and matched each component — starting from the power supply through the input board to the amplifiers and transducers right up to the complete HDL 28-A System

HIGH FREQUENCIES

LOW FREQUENCIES

FLYING ATTITUDE

The advanced rigging concept derives directly from its big brothers: the RCF HDL 30-A and HDL 50-A. The integrated mechanics are both fast and reconfigurable, allowing the system engineer to create J-shaped and spiral arrays. The hardware is designed for easy and fast setup. The angle can be adjusted on the ground before the system is hung and slipped automatically into the correct position as the array is pulled up. Up to 20 HDL 28-A modules can be fastened on a single flybar.

NEW PERSPECTIVE ON LINEARITY

RCF speakers are designed using a proprietary and advanced FiR filtering technology, conceived to deliver transparent sound, absolute clarity and perfect stereo images to the listener.

The special FiRPHASE filters allow to achieve coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies to the system.

THE IDEAL FLYABLE BASS COMPLEMENT

Theatrical and indoor requirements often need space in front of the stage, leaving no space for subwoofers.

The HDL 36-AS is the ideal flyable bass complement for the HDL 28-A array system.

It features one 4.0” voice coil, 15” Neodymium woofer to handle 135 dB SPL Max from 40 Hz to 140 Hz with maximum linearity and low distortion. The built-in 3200 Watt Class-D amplifier delivers excellent playback clarity and up to 135 decibels SPL max. With RDNet compatibility, the HDL 36-AS is part of the professional HDL System.
