Previewed to a very positive response at ProLight+Sound in April, the new Alcons LR24 pro-ribbon line-array system made its global debut at the NAMM show.
The LR24 is a 3-way, bi-amped “mid-size” format line-array system; Loaded with Alcons’ multiple-patented pro-ribbon technology for mid and high frequencies, the system features an unusually high dynamic range with a fast impulse response with up-to-90% less distortion. This results in an intuitive linear response, with optimal intelligibility and non-compressed identical tonal balance at any SPL.
The all-natural cylindrical wavefront of the purpose-designed RBN1202rs 12” pro-ribbon transducer and the acoustically and electronically symmetrical component configuration bring an industry-leading pattern control in both the vertical as well as the horizontal plane, up to the highest frequencies without any distortion-inducing horn constructions. The very-coherent vertical dispersion enables a non-destructive inter-cabinet coupling for maximum HF throw and wind-stability.
The RBN1202’s large 12" voice-coil features an unusual power handling of 2500W and RMS-to-peak ratio of 1:15, from 1.000 Hz to 20.000 Hz; This caters for a remarkable intelligibility combined with a virtually unlimited dynamic headroom reserve.
The MF-section, features two high-efficiency 6.5” midrange transducers with Neodymium motor-structure, coaxially mounted behind the HF driver in a horn-loaded configuration.
The LF-section delivers a tight and accurate low frequency with highest output under lowest distortion possible. The new-generation 12” transducers are fitted with a large, dual-3.5” voice-coil Neodymium motor, enabling a significantly-extended excursion, while maintaining a high sensitivity.
LR24 applications
The LR24 is driven by the Sentinel amplified loudspeaker controller, optimizing the system’s response by configuration-specific VHIR drive processing and feedback. The Signal Integrity Sensing pre-wiring ensures dynamic cable/connector compensation between the LR24 and ALC; This further enables a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load, with a system damping factor 10.000.
The patent-pending flying system facilitates both compressed and non-compressed suspension, while enabling angle-setting on the cabinets without lifting the array. It has a WLL of 24 cabinets under 10:1 safety.
Suitable for medium-to large touring and production applications, the LR24 system is inventory of “The Ribbon Network”; Alcons Audio’s international hire network. Due to the completely neutral, high dynamic and ultra-low distortion “Alcons signature sound”, the LR24 can be used for any application and source possible, from speech, to classical music, jazz, all the way to pop, EDM and hard-rock performances.
Tom Back, managing director Alcons Audio: “The LR24 is filling the gap we had between the compact LR18 and large-format LR28 pro-ribbon line-arrays and, as such, is a direct derivative of both systems, sharing features like low weight, bi-amped high output and the unique flying system of its larger sibling LR28. We had many requests from Alcons users that were looking for a high-end touring system solution, where the LR28 was simply too large for their majority of applications, but its sound performance was essential.”
