RCF HDL26-A Active Line Array Module

Description

The RCF HDL26-A Active Line Array Module is an ultra-compact bi-amped two-way active touring system for small and medium-sized events, both indoors and outdoors. Due to the advanced transducer design and the 2000W Class-D amplifier, among the best in its class, it is capable of an extended bottom-end and a pristine sound for a wide range of applications, alone or in RDNet managed line-array configurations. The HDL 35-AS is the ideal flyable bass complement for the HDL 26-A array system.

Features

The Acoustic Beauty of Symmmetry

The symmetrical design of the cabinet produces identical left and right coverage of 100°x10°. Component positioning and the special DSP crossover of the HDL 26-A ensures constant directivity, reducing spots of break up or attenuation.

The front baffle provides:

• Coplanar woofers
• Controlled LF dispersion with hybrid-bandpass design
• Central space to host the HF waveguide

Advanced Design

The integrated fittings are both easy to use and reconfigurable, allowing the system engineer to create J-shaped and spiral arrays starting at 1° angle. The hardware is designed for easy and fast setup. Up to 16 HDL 26-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.

Hybrid Bandpass Design

After many computer simulations, tests in anechoic chambers and listening sessions, the woofer arrangement in hybrid bandpass configuration results in wider and more coherent coverage, allowing a more effective frontal beam with only a few boxes. This arrangement increases the directivity of the line array, doubling the radiation points on low/mid frequencies. The shape of the baffle reduces the turbulence outside the waveguide decreasing the overall distortions.

Class-D Power

The amplifier is a central part of RCF’s product development. The HDL 26-A power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion and high signal-to-noise ratio. Class-D power amplifier technology operating at very low impedance produces extended transient response, while the high damping factor improves sound quality and detail. The amplifier module features +24 dBu input section, a solid machined aluminum structure which not only stabilizes the amplifier during transportation but also helps the fan-less heat dissipation. The low-latency DSP section deploys a remarkable amount of processing power for live performances with straight-forward control and monitoring of single parts of the module, including rigging angles and transducer performance via RDNet. An entire set of protections preserve product life and reliability.

Legendary Transducers

The RCF HDL 26-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 26-A System.
