IMPORTANT SAFETY PRECAUTIONS AND EXPLANATION OF SYMBOLS Install in accordance with instructions by QSC Audio Products, LLC 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.
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, WL118-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) WL118-sw The WL118-sw subwoofer extends the system’s low-frequency capability to 35 Hz. Its ceramic magnet, 4" voice coil, 18" transducer provides 850 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 Rules for Suspension • Correct use of all suspension hardware and components is imperative in sound system rigging and deployment. • Always calculate suspended loads before lifting to ensure suspension components and hardware are used within their respective load limits. • Research local codes and regulations to fully understand the requirements for suspended loads in the venue in which the equipment is to be suspended.
Attaching WL2082-i to Array Frame (Figure 1) Before beginning any installation, have your system designer calculate the proper splay angles using QSC’s EASE Focus (Array Calculator). All orientation of product is to be as viewed from the rear of the enclosure. Attach the array frame to the suspension structure using a 3/4" (20 mm) screw pin anchor shackle and appropriate sling, cable, etc. For arrays of four WL2082-i or less, assemble the cluster of WL2082-i on the ground using the included mating hardware.
Rigging the Installation Line Array (continued) Extension Bar (Figure 3) The extension bar rigging plates can be moved, if required, by removing the two 7/8" mounting bolts, moving to the selected mounting location, and reattaching. Tightening torque is to be 100 lb-ft of torque (135.6 N-m) EASE Focus software’s center-of-gravity calculator will provide a suitable point (or two points) for desired down-tilt.
Rigging the Installation Line Array (continued) Attaching the GS115-sw Ground Stack Rails to a WL118-sw (Figure 7) For all four rigging straps: Using an 6 mm hex wrench, remove the upper and lower rigging strap retaining bolts and loosen the two bolts in between. Pull the inner and outer straps to their outermost position; pull the center strap to its outermost position, and align the retaining bolt holes with the threaded inserts of the enclosure.
Rigging the Installation Line Array (continued) Attaching WL118-sw Behind WL2082-i Array Using EB2082-i (Figure 9) It is sometimes necessary to suspend the subwoofers behind the main array. Extreme splay angles may result in physical interference with rear-flown subwoofers. Attach both array frames to the extension bar rigging plates by centering the array frame member between the extension bar rigging plates and bolting together using the supplied 7/8" bolts.
WL2082-i Controls and Connections MODE Selection Switch (Figure 11) BI AMP: When set to BI AMP, an internal shading network removes the mid frequencies from one of the low-frequency 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 HORIZONTAL SHADING selector switch is not functional in tri-amp mode. Connect to the Speakon as shown for tri-amp (Table 2).
WL118-sw Connections Input Connections The WL118-sw input connectors are a pair of Neutrik NL8s wired in parallel for use in a 4-way system. A pair of Neutrik NL4's in Parallel are added for use as a stand alone subwoofer (Table 2).
