Rigging the Installation Line Array (continued)
Extension Bar
(Figure 3)
The extension bar rigging plates can be moved, if required, by removing the two 7/8
"
mount-
ing 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 WL118-sw to the Array Frame
(Figure 4)
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.
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 a 6 mm 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).
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
(Figure 5)
.
NOTE: When attaching one WL118-sw to another WL118-sw, you must use the
supplied ball-lock pins. This will allow for easier installation given the close
spacing between consecutive WL118-sw enclosures.
NOTE: When arraying two or more WL118-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.
