IMPORTANT SAFETY PRECAUTIONS Install in accordance with QSC Audio Product's instructions and under the supervision of a licensed Professional Engineer. WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation, placement or array.
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 subwoofer, 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.
Introduction (continued) WL115-sw The WL115-sw subwoofer extends the system’s low-frequency capability to 35 Hz. with a compact fourth-order bandpass enclosure. Its ceramic magnet, 4” voice coil, 15” transducer provides 650 watt continuous power handling capability. Many users of line array systems have found that suspending the subwoofers with the array provides audible benefit. Additionally, many venues lack physical space for floor-mounted subs.

Rigging the Installation Line Array (continued) Pull-Back Bar If using the pull-back bar, attach to the bottom enclosure at the bottom-most splay angle adjustment holes at the rear of the rigging plate by inserting the cap-head shoulder bolt through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. Use a 5/8” (16 mm) shackle to attach to the pull-back bar shackle hole located in the center of the main bar.
Figure 11: WL115-sw attached to FB2082-i. Rigging the Installation Line Array (continued) 3- Lower the array frame onto the enclosure, carefully aligning the rigging straps, and attach the top enclosure to the array frame by installing the ball-lock pins or M8 bolts. Before lifting, ensure the audio connection to the enclosures are correct and functioning. NOTE: When attaching one WL115-sw to another WL115-sw, you must use the supplied ball-lock pins.
Rigging the Installation Line Array (continued) Attaching WL115-sw behind WL2082-i array using EB2082-i Figure 15: EB2082-i with WL115-sw suspended at rear and WL2082-i array suspended at front. It is sometimes necessary to suspend the subwoofers behind the main array. Extreme splay angles may result in physical interference with rear-flown subwoofers.
WL2082-i Controls and Connections Figure 17: MODE selection switch. MODE Selection Switch BI AMP: When set to BI AMP, an internal shading network removes the mid-frequencies from one of the lowfrequency drivers. The BI AMP HORIZONTAL SHADING switch will select which transducer is shaded. TRI AMP: Shading network is NOT applied (shading must be provided by upstream signal processing). The Bi Amp Mode Horizontal Shading selector switch is not functional in tri amp mode.
WL115-sw Connections Figure 20: WL115-sw Input Plate Input Connections The WL115-sw input connectors are a pair of Neutrik NL8's wired in parallel. See Table 3 or the WL115-sw Input Plate for connector pinout. Note pin numbers 2+, 2-, 3+, 3-, 4+, and 4- are wired straight through from one connector to the other. This accommodates using one input cable assembly (where appropriate) for subwoofer and full range loudspeaker connections. Additionally, pin numbers 1+ and 1- of both NL8s are wired in parallel.
