Suspending the WideLine-8 Array
Attaching WL212-sw behind WL3082 array using EB3082 and
two AF3082-S array frames
1- Attach both AF3082-S array frames to the extension bar suspension plates by
centering the array frame member between the extension bar suspension plates
and bolting together using the supplied 3/4" bolts. The extension bar suspension
plates can be moved, if required, by removing the two 3/4"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.
2- Attach WL212-sw subwoofer(s) to the rear array frame
3- Attach WL3082 loudspeaker(s) to the front array frame.

NOTE: When stacking loudspeakers for attachment to array frames
using the extension bar, we recommend working with groups of 2
WL3082 for each WL212-sw. Start with no splay angle; this yields the
same height for landing the extension bar. Adjust splay angle once
the system is lifted.
Suspending 8 or less WL3082 Loudspeakers Using Two Pull-
Back Bars
NOTE: Do not suspend more than 8 WL3082 loudspeakers from a
PB3082 pull-back bar! Do not use PB3082 pull-back bar for suspend-
ing anything other than 8 or less WL3082 loudspeakers! Do not sus-
pend the WL212-sw from the PB3082 pull-back bar!
1- For arrays of 4 WL3082 or less, pin together the cluster of enclosures or pre-
pare pre-pinned array from transport cart. If constructing larger arrays we recom-
mended to first assemble units of four enclosures and then assemble the final
array by joining the four enclosure units to one another. Note the QSC logo on the
input plate will be right side up when the enclosure is oriented properly. During
assembly, ensure your splay angles are set as desired.
2- Pin one PB3082 to the top WL3082's front suspension plate attachment holes.
Ensure locking action of pins.
3- Attach a 5/8" (16 mm) screw-pin anchor shackle to the pull-back bar's center
shackle hole for lifting.
4- Pin a second PB3082 to the bottom WL3082's rear suspension plate. Ensure
locking action of pins. Use a 5/8" (16 mm) screw-pin anchor shackle attached
through a shackle hole for pulling back.

Warning! Eight (8) WL3082 loudspeakers is
the maximum allowable load (10:1 design
factor) for the PB3082. Do not suspend
more than eight WL3082 loudspeakers from the
PB3082.
