When searching for a new touring sound system there are essential prerequisites: higher SPL’s, constant directivity and sonic excellence. In today’s competitive world rental companies are looking for more, such as reduced weight, speed of rigging/derigging and ease of transportation. And once the system is in the air, with ever decreasing venue prep times, speed of optimisation using the inherent management software is vital.
The HDL System is changing the concept of large format arrays,
providing first class performance to an extended market of professional users.
The HDL System is composed of HDL 30-A and HDL 50-A, equipped with modern and innovative technology. Each component has been consistently and specially developed by RCF’s experienced engineering teams, 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 irrelevant in powered speakers where the amplifier is just a couple of centimeters away from the transducer. An active sound reinforcement system means more than just having amplifiers packed into a speaker housing. The real innovation is when each single component is controlled by individual DSP settings. Scaling a line array is the most important aspect when talking about best performance and coverage. Where passive systems have limits in impedance load or number of amplifier channels, an active RCF sound system is freely scalable and individually controllable. Having an HDL system gives you the freedom to work at many different locations with the same system, merely changing the number of modules.
INNOVACCIÓN EN TRANSDUCTORES
La línea de altavoces RCF incorpora una amplia gama de transductores que abarca todo el espectro de sonido. Diseñamos nuestros transductores para optimizar la pureza del sonido combinando de la ausencia de distorsión y la capacidad de resistir niveles altos de potencia durante largos periodos de tiempo. RCF desarrolla tecnología de transductores avanzada, incluyendo la aplicación de materiales de alta tecnología como neodimio, fibra de carbono, titanio puro, Kevlar, Kapton e híbridos del Mylar. Con más de 60 años de experiencia en diseño y fabricación, RCF ha desempeñado un papel fundamental en avances tecnológicos como el moldeado del cono en fibra de carbono, las arañas dobles de silicona, las bobinas interiores y exteriores, el bobinado de alambre rectangular y el modelado del diafragma en titanio puro. Nuestras últimas creaciones han dado como resultado circuitos magnéticos de neodimio de última generación, sistemas de ventilación de bobinas radicalmente nuevos y los innovadores montajes Direct Drive de bobinas.
DUAL SILICON SPIDERS
RCF’s original invention of the dual silicone sealed spider design offers many advantages: the two spiders offer double resistance to fatigue. The silicone between the cloth layers, being a very high memory material, provides the best shape stability to the spiders. The system, being sealed, functions as an air pump expelling hot air and drawing in cool air every time the cone assembly moves.
COMPLEX HYPER-VENTING COOLINGS
In our complex cooling designs individual components come together to create an ideal ventilation system. Finned cooling channels dissipate heat efficiently, the dust cap and the sealed spiders function as an air pump, expelling hot air and drawing in cool air every time the cone assembly moves. Many openings are situated directly on the transducer’s side and on the rear plate.
INSIDE - OUTSIDE VOICE COILS
RCF has developed a unique voice coil, combining the advantages of inside/outside technology to the superior quality of polyimideimide materials (wire resins and formers resins). The inside/outside coil offers many advantages:
- The dissipation surface is doubled
- The adhesion area to the former is doubled
- During thermal expansion the Former is squeezed between inside and outside layers offering the best mechanical resistance.
CUSTOM HIGH FREQUENCY WAVEGUIDES
The HDL custom 4PATH designed waveguide allows precise coverage of 90 x 10 degrees (HDL 50-A) and 100 x 15 degrees (HDL 30-A), while also delivering a superb, linear high frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from the crossover frequency to the highest audible frequencies.
DIRECT DRIVE VOICE COIL ASSEMBLIES
The top of the former is bent and bonded directly to the edge of the titanium diaphragm resulting in a Direct Drive configuration. Direct Drive guarantees optimal transfer of energy between the voice coil and the dome assembly, providing smoother, extended frequency response beyond 10 KHz, reducing break up modes and lowering distortion. This assembly delivers high power handling along with excellent mechanical and thermal properties that make RCF neodymium compression drivers robust and reliable.
HDL SYSTEM CONFIGURATIONS
From small rooms to big venues, the HDL system flexibility covers all the acoustic needs of the sound engineer.
Thanks to the full HDL accessory range and the infinite possibilities of the RDNet Networked Control, reaching the best listening experience on any venue is an easy task.
