Rigging the Installation Line Array (continued)

Attaching WL115-sw behind WL2082-i array using EB2082-i

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 sup- plied 7/8” bolts. 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 (135.6 N-m). Ease-Focus software’s center-of-gravity calculator will provide a suitable point (or two points) for desired down-tilt.

The rear suspended WL115-sw subwoofer(s) may now be attached to the array frame; see “Attaching the WL115-sw to the Array Frame”

The front suspended WL2082-i loudspeakers may now be attached to the array frame; see “Attaching WL2082-i to Array Frame”

NOTE: When stacking loudspeakers for attachment to array frames using the extension bar, we recommend working with groups of 2 WL2082-i for

each WL115-sw. Start with no splay angle; this yields the same height for landing the extension bar. Adjust splay angle once the rig is lifted.

Suspending 4 or less WL2082-i Loudspeakers Using Two Pull-Back Bars

NOTE: Do not suspend more than 4 WL2082-i loudspeakers from a PB2082-i pull-back bar! Do not use PB2082-i pull-back bar for suspending anything other than 4 or less

WL2082-i loudspeakers! Do not suspend the WL115-sw from the PB2082-i

Assemble the array of WL2082-i loudspeakers on the ground using the included mating

 

hardware. Ensure the notched rigging plate is on the right hand side (the system can only

 

be installed one way. Note the QSC logo on the input plate will appear right side up when

 

the enclosure is oriented properly.

 

Attachment of one enclosure to another is accomplished by inserting the cap-head shoul-

 

der bolt with washer through the mated rigging plates and appropriate splay angle selec-

 

tion holes and threading the lock nut (nylock) on the inside edge of the plates. The bolt

 

should be tightened snuggly to no more than 5 lb-ft of torque (6.8 N-m). See Figure 7 for

 

assembly detail.

 

Attach one PB2082-i to the top enclosure’s front, top rigging plate attachment holes by

 

inserting the cap-head shoulder bolts without washers through the mated pieces and

 

threading the lock nut (nylock) on the inside edge of the plates. The bolts should be tight-

 

ened snuggly to no more than 5 lb-ft of torque. See Figure 7 for assembly detail. 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 pull back bar for lifting.
