RCF HDL50-A-4K Active Large Format 3-way Line Array Speaker (8,000 Watts)

RCF HDL50-A-4K Active Large Format 3-way Line Array Speaker (8,000 Watts)

The RCF HDL50-A-4K is a professionally designed active 3-way line array module created intended for use in large-sized events, indoors and outdoors. It comes featuring a sound pressure level of 143 dB SPL that comes along with a built-in 8000 W PEAK, 4000W RMS Class-D four-channel amplifier. It is made with equipped eight best-of-class transducers, it is capable of offering an excellent playback quality which is ideal for professional musical applications. The proprietary 90 x 10 degrees 4PATH waveguide along with the symmetrical design of the cabinet is making it capable of delivering an optimal coverage.

• RDNet networked management and monitoring
• 48 kHz, 32 bit DSP processing
• 2 x 12” neodymium woofers
• 2 x 3” titanium dome neodymium compression drivers
• Remarkably compact and lightweight

THE MOST POWERFUL HDL ARRAY EVER MADE BY RCF
The 4K amplifier is capable to double the power of the HDL 50-A capable of achieving the new levels of clarity and absence of distortion. Transducers work at full performance and the SPL output is more than doubled. Furthermore, we enhanced the power supply section that comes along with a tripled current level on fast transients, intended for a level of detail which are usually achieved only in high-end studio monitors.

FASTER AND MORE POWERFUL
The 4K amplifier is made as an essential part of HDL 50-A reengineering effort. The 4000 W RMS Class-D power is capable of operating at very low impedance for the production of a quick and detailed transient response, and the high damping factor improves sound quality and detail at the same time.

The HDL 50-A 4K power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion and high signal-to-noise ratio. The amplifier module features a solid machined aluminum structure that stabilizes the amplifier during transportation.

The control panel on the back adjusts volume, bypass, delay, presets and advanced functions. The signal input preamplifier features a double opto isolation to avoid noise and ground loops.

DSP PROCESSING
New generation DSP is capable to handle the processing inside the cabinet and is allowing for the adjustment of Cluster size and HF projection. The low-latency 32 bits DSP section deploys a remarkable amount of processing power for live performances with straight-forward control and monitoring of individual sections of the module, including the onboard inclinometer and transducer performance via RDNet. An entire set of protections preserve product life and reliability. All settings are controllable by the encoder on the rear of the cabinets or using the integrated RDNet remote management. The easy-to-access control panel allows for simple optimizations of the module.

RCF RDNet
NETWORKED CONTROL AND MUCH MORE
RDNet is a professionally designed robust management network and control platform intended for use in 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.

V-SHAPED SYMMETRICAL DESIGN
The symmetrical design of the cabinet produces identical left / right coverage. The component arrangement and the special DSP crossover filtering of the HDL 50-A allow for a constant directivity without spots of break up or attenuation. The V-SHAPED front baffle provides:

• Coplanar midranges and woofers
• Controlled LF dispersion
• Central space to host the HF guide

4 PATH WAVEGUIDE
The custom 4PATH designed waveguide allows a precise coverage of 90 x 10 degrees, while also delivering a superb, linear high frequency response. The unique shape of the four ducts forming the guide create an ideal isophasic load from 800 Hz to the highest audible frequencies.

NEODYMIUM RCF PRECISION TRANSDUCERS

HIGH FREQUENCIES - Two ND 840 large format compression drivers are one of the key advantages of the HDL 50-A. The 3.0” voice coil allows for a crossover point of 800 Hz. The driver itself delivers a sizable portion of vocal range with better intelligibility.

MID FREQUENCIES - 4 x 2.0” voice coil 6.0”neo midranges - Water resistant fiber doped cone - Polycotton M-roll surround - High power magnetic structure

LOW FREQUENCIES - 2 X 3.0”voice coil neodymium 12” woofers - Water resistant fiber doped cone - Polycotton M-roll surround - Hypervented magnetic structure

CABINET
The RCF engineers constructed an innovative housing consisting of rigid plywood and polypropylene side panels with integrated handles to lower the total weight.

FLY-WARE & HARDWARE
The integrated rigging hardware is both fast and reconfigurable, allowing the system engineer to create J-shaped and spiral arrays starting with 0.5° splay angles. The angling of the system develops on a single backbone. Up to 20 HDL 50-A 4K modules can be fastened on a single flybar. The hardware design let angle adjustments before use / on the ground and slip automatically into the correct position when pulling up the array. The system administrator has then only to fix it with a lock pin. Easy and fast set up. The heavy-duty front grille is powder-coated. A special transparent-to-sound foam backing inside helps to further protect the transducers from dust.

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.
