Alcons Launches LR28/110 Wide Dispersion Larger Format Line Array
Alcons has launched the LR28/110 Wide Dispersion Larger Format Line Array — a three-way, line-source sound system for use as vertical array with extended horizontal coverage in up to the largest applications.
Originally introduced in 2015, the LR28/80 features an 80º horizontal dispersion pattern, but is identical to the new, wide-dispersion LR28/110 in all other aspects. Both models combine the highest sound quality possible with very high SPL capabilities and throw. It is a true ‘what you mix is what you get’ (WYMIWYG) solution, where the system doesn’t add anything to the original source: input = output.
The RBN1402rsr and mid section (featuring four high-efficiency 6.5″ midrange transducers) are jointly mounted on an aluminium cassette for optimised heat-dissipation/reduced power-compression and prolonged system output.
The LF section comprises two reflex-loaded, custom 14″ woofers with reinforced cone and large voice-coil Neodymium motor structure for improved heat dissipation and reduced power compression.
The LR28/80 and LR28/110 are powered and controlled by four channels of the Sentinel10 amplified loudspeaker controller; Through the integrated processing and feedback, the ALC offers LR28-specific drive processing with array compensation, filter-presets, system EQ, phase-matching and other facilities. The Signal Integrity Sensing pre-wiring of the LF and MF sections ensures dynamic cable/connector compensation between the LR28 and Sentinel, resulting in a fast, tight mid/bass response and reducing distortion even further.
The patent-pending rigging system enables angle setting on the cabinets without lifting the array, resulting in safer and faster set-up with minimal handling. The flying system facilitates two different ways of array assembling — caterpillar and pre-rig-style — with compressed and non-compressed suspension. It has a WLL of 24 cabinets under 10:1 safety.
The LR28/110 is element of the Alcons application-configurable touring package, including the LR28 line-arrays, LB28 bass array-extension, BC543 cardioid subwoofer system, Sentinel amplified loudspeaker controller, ARC 3D-simulation tool and power / signal- distribution and transport logistics.
