Rigging proceduresStacking an SB18/Kara mixed array or an SB18 standalone arrayUsing M-BUMPModeling and safetyAn SB18/Kara mixed array or an SB18 standalone array can be stacked directly on the ground (ground stacked array)or onto an M-BUMP/M-BAR/M-JACK platform (platform stacked array). The gure below shows a mixed array of eachtype and gives the associated conditions of use.Ground stacked array Platform stacked array• To be stacked on a perfectly horizontal and regularsurface ONLY• Provides tilt adjustments in case of slope surface• Increases Kara array site angle rangeGround stacked arraysA ground stacked array requires to be installed on a perfectly horizontal and regular surface. It can be composedof a maximum of 4 SB18/9 Kara or 8 SB18 enclosures along with all loudspeakers cables (refer to Mechanicalsafety (p.26)).Apply the setup safety limits given in the table below regarding the angle between the top SB18 and the bottomKara (refer to Array site angle setting (p.196) for bottom Kara angle settings):Kara owner's manual (EN) version 1.0 113
