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.

pending a maximum of 8 WL3082 loudspeakers.

rear and WL3082 array suspended at front.

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.
