ACTIVE TWO-WAY LINE ARRAY MODULE
The RCF HDL30-A is a compact bi-amped 2-way active touring system for medium to large events, both indoors and outdoors. It features two 10-inch woofers and an impressive 4-inch titanium compression driver. The time coherent waveguide is the result of in-depth research and design. HDL 30-A is the first line array in a composite cabinet with zero-degree phase and ultra-linear amplitude response. The built-in 2200 watt class-D amplifier delivers excellent playback clarity and up to 137 decibels SPL max. The RCF HDL 30-A features state of the art RCF transducers with neodymium magnets.
HDL 30-A is an incredible achievement for RCF. An ultra compact and lightweight system with a top of the class rigging and superior sound.
The symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL 30-A take care of the constant directivity without spots of break up or attenuation.
The originally designed front baffle provides:
4 PATH WAVEGUIDE
The custom 4 PATH designed waveguide allows a precise coverage of 100 x 15 degrees, while also delivering an excellent, linear high-frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from 680 Hz to the highes t audible frequencies.
POWERFUL CLASS D AMPLIFIERS
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.
The high strength enclosure in composite polypropylene has a revolutionary new rigging concept inspired by its big brother: the RCF HDL-50A. Compared to its acoustical power, it has a remarkably low weight for easy handling and flying.
The integrated mechanics are both fast and reconfigurable, allowing the system engineer to create J-shaped and spiral arrays starting with 0.2° angles. The hardware is designed for an easy and fast setup. The angle can be adjusted before to hang the system, on the ground, and slip automatically into the correct position when pulling up the array. Up to 20 HDL 30 -A modules can be fastened on a single flybar.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.
A NEW PERSPECTIVE ON LINEARITY
RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency. Up to 3 FiRPHASE filters are available for each module on RDNET to manually shape the high frequency response.
