Introduction
The Installation Line Array (ILA) is a high performance line array system designed for the needs of Houses of Worship, Performing Arts facilities and a multitude of other venue types. The current ILA family is composed of the WL2082-i line array element, WL115-sw sub- woofer, FB2082-i array frame, PB2082-i pull-back bar, EB2082-i extension bar, and GS115-sw Ground Stack Kit.
Installation Line Arrays may be used in outdoor applications where the system is somewhat protected from the elements. The enclosure material is formulated with UV inhibitors, the grille is made of aluminum and the woofer cones are weather resistant.
WL2082-i
The WL2082-i line array element uses two high-power, neodymium magnet, 2" voice-coil, 8" low-frequency drivers in a two-and-a-half way configuration. Both woofers produce low-frequencies but only one covers the mid-range, resulting in far better horizontal directivity control in the crossover region. Excellent high-frequency output and clarity are provided by a pair of 1.75" voice coil, neodymium magnet compression drivers with titanium diaphragms. These drivers are mounted to a multiple-aperture diffraction waveguide that provides an extremely wide horizontal coverage of 140º. As a result, systems will rarely require side or center fill speakers and solid stereo imaging is preserved across the listening area.
The low-frequency capability of a WL2082-i array extends to 68 Hz (-10 dB); adequate for speech/vocal and acoustic music program mate- rial. For reinforcement of program material with more demanding low-frequency content, the WL115-sw companion subwoofer is avail- able.
