Alcons introduces "What You Mix Is What You Get!"

Alcons introduces "What You Mix Is What You Get!"

The Netherlands - The LR24 is a 3-way, "larger-format" line-source sound system, to be used as vertical array, either in stacked or flown configuration, for even the largest sound reinforcement applications.

The LR24 is redefining sound reinforcement, as it combines a HiFi-grade sound quality with very high SPL capabilities. Loaded with Alcons’ proprietary pro-ribbon technology for mid and high frequencies, the LR24 offers very fast impulse response with full-dynamics, up-to-90% less distortion under lowest power-compression. The all-natural (Isophasic) cylindrical wavefront of the pro-ribbon HF transducer enables a precise pattern control, without any distortion-inducing horn constructions.

Philip "Dr. Phil" de Haan, head of Alcons R&D and initiator of multiple patents: "Until now, this extraordinary high level of precision in sound quality was not obtainable in sound reinforcement, especially not at these sound pressure levels. With the new RBN02 pro-ribbon transducer platform, the HF output capabilities lie above that of the largest line-array system."

De Haan continues: "The design objective was to create a system with an absolutely neutral, 1:1 non-coloring and predictable linear response behaviour at any sound pressure level, with highest projection accuracy. Thanks to our 25+ years experience in pro-ribbon transducer technology, DSP electronics and acoustics we were able to realize our goal: What you mix is what you get!."

The HF section features the RBN1402rsr pro-ribbon driver with 14-in. voice-coil. The combination of the high sensitivity + the unusually high HF peak power handling of 3000W caters for a unique intelligibility and throw with ample dynamic headroom reserve under any condition. The purpose-designed Alcons RBN1402rsr driver features no less than 4 patents.

The MF-section features 4 high-efficiency Neodymium 6.5" midrange transducers in a symmetrical loaded configuration; The MF section is made out of aluminium and forms an integral part with the HF section, for optimized heat management, maintaining high-output over a longer period of time.

The LF section consist of two long-excursion, reflex-loaded 12" woofers with carbon-reinforced cones. The Neodymium motor-structure features a 4" voice-coil and dual-spider suspension with forced-venting, again for improved heat dissipation and reduced power compression.

The SignalIntegritySensing pre-wiring of the LF and MF sections ensures a fully dynamic cable/connector compensation between the LR24 and Sentinel, resulting in a fast and tight mid and bass response, regardless of impedance or cable length, while reducing distortion even further (system damping factor >10.000).

The LR24 has a linear frequency response from 51Hz to 20.000Hz (-3dB), where the low-end control can be extended by the LB24 double-12" bass array-extension with the same cabinet foot print. The horizontal dispersion of 80-degrees is maintained down to 190Hz. The vertical dispersion enables a maximum cabinet splay angle of 6-degrees, still maintaining complete wavefront coherency without any disruption or lobing up to 20.000Hz.

The system is to be exclusively driven by 4 channels of the Sentinel, Alcons’ proprietary 10kW amplified loudspeaker controller. Through the integrated (steering) processing and feedback, the ALC offers LR24-specific drive processing with optimal response, directivity, reliability and user-friendliness.

Utmost reliability is one of the main essentials for Alcons systems: Each transducer design has to pass a rigorous 1000 hour test at maximum (clip) levels. This is a key element in Alcons’ transducer design.

The rigging system enables angle-setting on the cabinets, without lifting the array: This results in faster set-up times with minimal handling. The flying system supports different ways of array assembling, per single cabinet or 4-cabinet pre-rig and is certified for 24 cabinets in a 10:1 safety ratio.

The LR24 is element of a complete, application-configurable package, including the LB24 bass array- extension, BC543 triple 18" cardioid subwoofer system, Sentinel amplified loudspeaker controller, ARC™ 3D-simulation tool and system connection and transport logistics.

The LR24 is part of "The Ribbon Network" inventory, Alcons’ global dry-hire and partner network and comes with a 6-years "no hassle" warranty.
