Kara — Stacking Onto an SB18 Array (Rigging) — Tools

SB18 & Frame Setup

Stack an SB18 enclosure onto an M-BUMP/M-BAR/M-JACK horizontal platform per the SB18 Rigging Manual (external document), or place the SB18 on the ground for a ground-stacked configuration. Place a second M-BUMP at the rigging location, oriented so the identification plate text is upside down and the laser slits point toward the audience, and place it on the SB18. Connect the 4 connecting points between the M-BUMP and the SB18: on each point, remove the external T-BLP from the M-BUMP, open the rotating arm, and secure it to the SB18 by reinserting the T-BLP. (Optional) Mount both KARA-ANGARMEX angle arm extensions to the M-BUMP: for each, remove the storage T-BLP and rear R-BLP, insert the angle arm extension into the M-BUMP vertically with its sling ring toward the front and indentation on the spacer, align the holes, and insert the R-BLP. Remove both front R-BLP from the M-BUMP — if configured without angle arm extensions, also remove both rear R-BLP. Place a full flight-case at the stacking location and remove the cover (enclosures KARA#1-3, top to bottom).

Set KARA#1 in stacking configuration on both sides: remove the front top R-BLP from storage, rotate the front arm up, slide it down, and secure with an R-BLP in the yellow link hole; remove the rear top R-BLP from storage, slide the angle arm to the desired angle, and secure with an R-BLP in the corresponding angle hole; then remove the front and rear bottom link R-BLP and reinsert them into their bottom storage holes. Connect KARA#1 to the M-BUMP: lift and turn KARA#1 with its arms downward and front face toward the audience, insert the 4 arms into the M-BUMP's connecting points (using the angle arm extensions' rear points if installed), then secure the front connecting points with R-BLP on the M-BUMP and the rear connecting points with either R-BLP on the M-BUMP or T-BLP on the angle arm extensions, depending on the configuration. Set KARA#2 in stacking configuration by repeating the KARA#1 stacking-configuration method. Connect KARA#2 to KARA#1: put KARA#2 upside down with its front face toward the audience, insert its 4 arms into KARA#1's connecting points, then move KARA#1's 4 top storage R-BLP into the top yellow link holes. Connect KARA#3 to KARA#2 by repeating the KARA#2 stacking-configuration and connection methods — do not remove KARA#3's 4 bottom R-BLP from storage, since it's the topmost enclosure. Recheck that the stacking platform is still horizontal — if not, re-level it using an inclinometer and the M-JACK adjustment method.
