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. 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 WL118-sw subwoofer(s) may now be attached to the array frame; see
“Attaching the WL118-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.”
– Figure 9 –
– Figure 10 –
NOTE: When stacking loudspeakers for attachment to array frames using the
extension bar, we recommend working with groups of 2 WL2082-i for each
WL118-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 Four or Less WL2082-i Loudspeakers Using Two
Pull-Back Bars
(Figure 10)
NOTE: Do not suspend more than four 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 WL118-sw from the PB2082-i
pull-back bar!
NOTE: A washer should not be used when attaching the pull-back bar. This will
allow the pull-back bar to pivot freely.
Warning! 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.
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 shoulder bolt
with washer through the mated rigging plates and appropriate splay angle selection 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).
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 tightened snuggly to no more than 5
lb-ft of torque. See
(Figure 1)
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.
Attach the second PB2082-i 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 bolts
without
washers
through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. The
bolts should be tightened snuggly to no more than 5 lb-ft (6.8 N-m) of torque. 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.
