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. Any such condition severely reduces the safety of the installation and should be immediately corrected.
Use only hardware which is rated for the loading conditions of the installation and any possible short-term, unexpected overloading. Never
exceed the rating of the hardware or equipment.

Consult a licensed, Professional Engineer regarding physical equipment installation. Ensure that all local, state and national regulations
regarding the safety and operation of suspended equipment are understood and adhered to.

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. 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 mate­rial. For reinforcement of program material with more demanding low-frequency content, the WL115-sw companion subwoofer is avail­able.

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. For these reasons, the WL115-sw includes rigging hardware and, with selection of the appropriate
rigging accessories, subwoofers may be flown at the top of or behind a WL2082-i array.

Rigging

Rigging the Installation Line Array is simple and flexible. Enclosures are bolted together with the provided M8 shoulder bolts or pinned
together with optional quick-release ball-lock pins.

The FB2082-i array frame supports most flown array applications, and the EB2082-i extension bar supports suspension where the center of
gravity is beyond the limits of the FB2082-i. Additionally, the EB2082-i is used for arrays where subwoofers are flown behind the main array.
The PB2082-i pull-back bar is used for pulling back the bottom element of the array for aiming and stability or as the primary suspension com­ponent for certain small arrays.

Ground stacking is easily accomplished using the GS115-sw Ground Stack Kit. The kit includes two ground stack rails which attach to the rig­ging straps under the WL115-sw. These rails provide added stability and allow for ground stacked arrays to be constructed.

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.

•Use only shackle holes for suspension of array.

•Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can have hid­den structural weakness.

•Consult a Professional Mechanical or Structural Engineer licensed in the jurisdiction of the sound system installation to review, verify, and
approve all attachments to the building or structure.

•Never assume anything- Owner or third-party supplied suspension attachment points may not be adequate for the loads to be suspended.

•Employ the services of a Professional Rigger for hoisting, positioning, and attaching the equipment to the supporting structure.

•Always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for cracks, wear, deforma­tion, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly before lifting. Discard any worn, defective, or
suspect parts and replace them with new appropriately load-rated parts.

Shock Loading

When a load is either moved or stopped, its static weight is magnified. Sudden movements can magnify the static weight several times. This
magnification of static weight is termed "shock loading". Shock loading poses a danger to equipment and workers. The effects of shock loading
can be instantaneous, or they may remain undetected unless the equipment is visually damaged. Avoiding shock loading requires careful plan­ning and knowledge of equipment, rigging, and lifting practices.

Shock loading of equipment and structures is usually confined to lifting and installation, but natural forces (winds, earthquakes) can impose
shock loads several times the static load. This is why structures and suspension equipment must be capable of supporting several times the
weight of the equipment suspended.

ILA Working Load Limits and Design Factors

Table 1 lists the ILA suspension components and provides Working Load Limit data at various Design Factors. The tabulated Design Factors are
for static loads only. The choice of which Design Factor to use will depend upon the jurisdiction and venue of installation, as well as the condi­tions of suspension. Dynamic conditions are determined by unknown, installation-specific factors and should be referred to a Licensed Structural
Engineer for clarification before proceeding with any suspension of the equipment. The data presented is based upon the listed component
weights:
