Kara — Standalone Array Rigging

Flying a standalone KARA array (two 3-box sub-arrays) from an M-BUMP, with an optional pull-back configuration. Reference: LA-KARA-FLY-STD-RIG-01. Follow in order — this is a sequential rigging procedure, not an independent checklist; steps depend on the ones before them.

Safety notes

M-BUMP can nominally fly up to 24 KARA enclosures (max decreases with array curvature — verify in Soundvision).
All ball-locking pins (BLP) must be fully inserted at every step.
Check every shackle bolt is fully screwed and secured with its safety pin.
If using pull-back, max downward angle depends on array composition (e.g. 12 KARA/0 SB18 → max −90°, 9 KARA/3 SB18 → max −60°) — verify in Soundvision.

Frame Setup

Place an M-BUMP at the rigging location, oriented so the identification plate text is readable and the laser slits point toward the audience. (Optional) Install one or two M-BAR onto the M-BUMP by removing the T-BLP, inserting the M-BAR studs into the desired holes, and securing with the T-BLP. Attach the shackle(s) to the M-BUMP per the desired rigging configuration.

Building Array 1

Place a full flight-case at the rigging location, remove the cover, and orient the first 3-KARA array (ARRAY#1, KARA#1-3) with its front face toward the audience. Check the inter-enclosure connections in ARRAY#1 on both sides: front connecting points open and locked by 2 R-BLP in the yellow link holes; rear connecting points with the angle arm cursor at 0° and locked by 2 R-BLP. On KARA#1, deploy the four arms on both sides: front arm rotated up, slid down, and secured with an R-BLP in the yellow link hole; rear arm slid to align the cursor with 5° (recommended so KARA#1's axis stays parallel to the M-BUMP) and secured with an R-BLP in the angle hole. Remove the 4 R-BLP from the M-BUMP, place the M-BUMP onto ARRAY#1 aligning the 4 connecting points, and secure by reinserting the 4 R-BLP. Place ARRAY#1 beneath the connecting points, attach the motor hook(s)/stinger(s) to the shackle(s), raise to a reachable height, and remove the flight-case from the rigging location. With two people working simultaneously on each side, set ARRAY#1's inter-enclosure angles: grab KARA#3's back handle, remove KARA#2's rear top R-BLP, rotate KARA#2 to align the angle-arm cursor with the desired angle, secure with an R-BLP in the corresponding angle hole, then repeat for KARA#3.

Building Array 2

Place a second full flight-case, remove the cover, and orient the second 3-KARA array (ARRAY#2, KARA#4-6) with its front face toward the audience. Check the inter-enclosure connections in ARRAY#2 on both sides (same check as for ARRAY#1). On KARA#4, take both front arms out on each side — remove the front top R-BLP, rotate the front arm up, and slide it down — without reinserting the R-BLP yet. Raise ARRAY#1 slightly higher than ARRAY#2's front arms and place ARRAY#2 beneath ARRAY#1. Connect the front connecting points between ARRAY#1 and ARRAY#2: slide KARA#4's front arms up to align with KARA#3's bottom front connecting points, move KARA#3's bottom R-BLP from storage into the bottom yellow link holes, lower the array until the KARA#3/KARA#4 front corners contact, and secure KARA#4's front arms with R-BLP in the top yellow link holes. Raise the array to a reachable height and remove the flight-case from the rigging location. With two people working simultaneously on each side, connect the rear connecting points between ARRAY#1 and ARRAY#2: remove KARA#4's rear top R-BLP from storage, slide the angle arm to the desired angle, secure with an R-BLP, grab KARA#6's back handle to rotate ARRAY#2 and align the KARA#3/KARA#4 rear connecting points, then move KARA#3's rear bottom R-BLP into the yellow link hole. Set ARRAY#2's inter-enclosure angles by repeating the ARRAY#1 angle-setting method.

Optional Pull-back & Raising

(Optional, pull-back configuration) Attach KARA-PULLBACK to KARA#6: insert the PULLBACK studs into KARA#6's connecting points with the long studs at the back, move the 4 bottom R-BLP from storage into the bottom yellow link holes, and attach an additional motor's hook/stinger to the KARA-PULLBACK shackle. Raise the array to the desired height and adjust the site angle per the chosen rigging configuration. Attach two safety slings (not provided) between the M-BUMP and the main rigging structure.
