The HDL10-A Active Line Array Module from RCF is designed for use in live sound reinforcement and installed situations. The system is powered from a 1400W Peak Power two-way digital amplifier (split 400W for the HF and 1000W for the LF), and sound is processed from a powerful DSP. The system features two 10" transducers with a 2.5" voice coil for a solid bass reproduction, and a large format 2" compression driver to deliver vocal clarity and high definition. The custom-designed waveguide allows a coverage of 100° x 15°, whilst also delivering linear high frequency response.
The ND 640 compression driver's 2.5" voice coil allows a crossover point of 800Hz, which allows a wide vocal range to be produced by this driver. The DSP also includes presets for indoor/outdoor usage and highly curved arrays.
The back-panel controls on the allow a number of simple optimizations to be carried out: two possible HF settings, four possible cluster configurations, an EQ setting for high curved configurations, and an Indoor Correction EQ. A volume knob allows to set the overall volume of the speaker according to its application. This unit provides Power, Signal, and Status LEDs for monitoring the system.
The HDL10-A features configurable mechanics, angles between cabinets are selectable with 2° resolution and allow the system engineer to create J-shaped or spiral arrays. HDL10-A cabinets are molded on a polypropylene composite material designed to dampen down vibrations even at maximum volume settings. The module is equipped with two aluminum side handles with a rubber handgrip for portability. The system is equipped with a heavy duty fly bar. The steel construction mechanics make it possible to fly up to 16 modules in daisy chain manner.
