LINE ARRAYS By Bennett Liles
AltasIED EL1503-B
For some time now, line arrays have proven a powerful tool in sculpting sound coverage with consistent frequency response, high SPL, and suppression of unfavorable lobes. Proper rigging also reduces setup and strike time along with enhancing safety. Originally used almost exclusively for touring operations, line arrays now enjoy a solid market position in permanent installations with both passive and self-powered units. The products shown here illustrate how far line array technology has come and the promise it shows in the reemergence of live events.
For a precise sound pattern down to 300Hz and very unobtrusive appearance in small rooms, the AtlasIED EL1503-B full range line array system is a very effective solution. Its fifteen proprietary 3in. drivers are mounted in a sealed Baltic birch enclosure finished in heavy duty black Duracoat. The LF response can be extended by addition of the A-Line ELW110A-B/ELW110X-B low frequency speaker system. The EL1503-B is designed to be run by the ELW110A-B powered low frequency driver and amplifier combination. Capable of 4-ohm and 8-ohm operation, each column is connected with NL4 Speak-ON terminals for quick and secure hook-up. Bose The versatility of line arrays is showArenaMatch AM40
cased in the Bose Professional ArenaMatch AM40 with its DeltaQ replaceable waveguides for variable directivity. Each array element uses a 14in. neodymium woofer and six Bose EMB2S titanium-diaphragm neodymium compression drivers to deliver high SPL for long throw applications. The ArenaMatch line can take it all outdoors featuring a water-resistant woofer cone coating, three-layer stainless steel grille, industrial polyurethane exterior coating, and a protective molded input cover. Coverage is tailored with a selection of 10, 20 and 40-degree modules. Installation options include bi-amp capability, passive crossover, and 70/100V transformer inputs. They are also EN54 certified for fire detection and alarm systems.
Available in a number of variants to suit specific environments, the Clair Brothers i212 is a three-way active line array element with a frequency response of 45Hz to 20kHz. The cabinet houses two 12in. woofers, four 6in. mid-range drivers and two 3in. voice coil diameter HF drivers. Operating at a nominal 8-ohm impedance, the unit’s power handling is 1800W (LF), 720W (MF), and 320W (HF). The standard dispersion is 90 degrees horizontal x 10 degrees vertical but there is also a 120 degree horizontal by 10 degree vertical option. The cabinet connects on two EP-8 terminals and there is integral bimodal rigging capability. The DAS Audio Aero 50 three-way large
