M-BUMP Rigging structure The L-Acoustics M-BUMP rigging structure has been designed to y or stack the Kara enclosures as a variable-curvature, vertical line source array. M-BUMP also allows Kara to be rigged to an SB18 subwoofer array. M-BUMP also can y straight vertical SB18 arrays.
KARA-MINIBU Rigging structure The L-Acoustics KARA-MINIBU rigging structure has been designed to y or stack the Kara enclosures as a variable- curvature, vertical line source array. KARA-MINIBU also allows Kara to be attached to an SB18 subwoofer array. KARA-MINIBU also can y straight vertical SB18 arrays.
The L-Acoustics M-BAR extension bar is a complementary rigging element for M-BUMP. Optionally used as a single element or in pair in own congurations, it will extend the site angle capability of Kara and SB18 arrays. In stacked congurations, its use is required in pairs as part of the stacking platform (see M-JACK, KARA-ANGARMEX (p.21)).
M-JACK, KARA-ANGARMEX Stacking platform (with optional angle arm extensions) The L-Acoustics M-JACK are four feet to be used along with one M-BUMP and two M-BAR so as to form a stacking platform for a variable-curvature, vertical Kara line source array.

The L-Acoustics KARA-MINIBUEX is a set of two complementary rigging plates for KARA-MINIBU to adapt to the SB18 enclosure or to stack Kara. The L-Acoustics KARA-ANGARMEX is a set of two angle arm extensions providing extra 10° downwards site angle for the bottom Kara in stacked congurations.
The L-Acoustics KARA-PULLBACK rigging accessory will allow setting the Kara array in a pullback conguration. It connects to the bottom enclosure of the array and to the hook or stinger of an additional motor. The KARA-PULLBACK is a plate on which is xed one shackle tted with 19 mm/0.75 inch-diameter bolt and a safety pin.

Page 52
Remove the rear top R-BLP, slide the angle arm so as to align the cursor with the 5° angle value, and secure by re- inserting the R-BLP into the corresponding angle hole (1°/3°/5°/7.5°/10°). It is recommended to select the 5° angle on the Kara intended to be linked to the M-BUMP. In that way the KARA#1 axis will be parallel to the M-BUMP.
Page 53
11. Check the inter-enclosure connections in ARRAY#2 by applying step (p.51). 12. On KARA#4, take both front arms out as follows (repeat for each one): remove the front top R-BLP, rotate the front arm up, and slide it down. Do not re-insert the R-BLP.
Page 54
ARRAY#2 as follows: a) Remove the KARA#4 rear top R-BLP from its storage position, slide the angle arm so as to align the cursor with the desired angle value, and secure by re-inserting the R-BLP into the corresponding angle hole (0°/2°/4° or 1°/3°/5°/7.5°/10°).

Using M-BUMP Modeling and safety An 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 each type and gives the associated conditions of use.
Page 114
• Determine the number of required Kara enclosures. • Calculate the inter-enclosure angles. A platform stacked array can be composed of a maximum of 2 SB18/6 Kara or 4 SB18 enclosures along with all loudspeakers cables (refer to Mechanical safety (p.26)).
