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. [. . . ] All orientation of product is to be as viewed from the rear of the enclosure. This will allow the pull back bar to pivot freely. Figure 9: Bolting order for EB2082-i Extension Bar rigging plates. Extension Bar 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. Attach the array frame 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. Attaching the WL115-sw to the Array Frame All orientation of product is to be as viewed from the rear of the enclosure. The QSC logo on the input plate will appear right side up when the enclosure is oriented properly. 1- Attach the array frame to the suspension structure using 3/4" (20 mm) shackle and appropriate sling, cable, etc. . . . For all four rigging straps: Using an 6mm 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. Re-install the outermost rigging strap retaining bolts and tighten all four bolts on each strap to 13 lb-ft (17. 6 N-m). Figure 10: Extending the WL115-sw rigging straps. 8 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. This will allow for easier installation given the close spacing between consecutive WL115-sw enclosures. NOTE: When arraying two or more WL115-sw subwoofers, it is easiest to lay the enclosures on their backs, align and mate the rigging straps, and install the ball-lock pins. When installing the ball-lock pins, ensure full insertion and locking action. Figure 12: WL115-sw to WL115-sw rigging. Attaching the GS115-sw Ground Stack Rails to a WL115-sw 1- For all four rigging straps: Using an 6mm 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. Re-install the outermost rigging strap retaining bolts and tighten all four bolts on each strap to 13 lb-ft (17. 6 N-m). 2- Position a GS115-sw Ground Stack rail between the rigging straps on the right and one to the outside of the rigging straps on the left side of the loudspeaker. 3- Attach the rail to the rigging strap by inserting the cap-head shoulder bolt with washer through the mated components and threading the lock nut (nylock) on the inside edge of the assembly. The bolt should be tightened snuggly to no more than 5 lb-ft (6. 8 N-m). NOTE: GS115-sw must be attached to at least one WL115-sw for stability before any additional loudspeakers are attached. NOTE: GS115-sw is designed to accommodate up to two WL115-sw loudspeakers and up to six WL2082-i loudspeakers. [. . . ] Use a 5/8" (16 mm) screw pin anchor shackle to attach to the pull-back bar shackle hole located in the center of the main bar for pulling back. Four (4) WL2082-i loudspeakers is the maximum allowable load (10:1 design factor) for the PB2082-i. Do not suspend more than four WL2082-i loudspeakers from the PB2082-i. WL2082-i Controls and Connections 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. [. . . ]
