Alcons to Debut LR24 Pro-Ribbon Line-Array System at ISE

Alcons LR24 line-array speakerThe new Alcons LR24 pro-ribbon line-array system will be making its global debut at ISE. The LR24 is a three-way, bi-amped “mid-size” format line-array system with Alcons’ patented pro-ribbon technology for mid and high frequencies and the system features an unusually high dynamic range with a fast impulse response with up-to-90% less distortion.

The all-natural cylindrical wavefront of the purpose-designed RBN1202rs 12” pro-ribbon transducer and the acoustically and electronically symmetrical component configuration bring a 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 2500 watts and an RMS-to-peak ratio of 1:15, from 1.000 Hz to 20.000 Hz. The MF-section features two high-efficiency 6.5″ midrange transducers with a 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 the highest output under the 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.

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.

The LR24 system is designed for medium-to-large touring and production applications and is part of the inventory of “The Ribbon Network,” Alcons Audio’s international network for dry-hire cooperation of Alcons systems.
