Rigging procedures
Using KARA-MINIBU
Modeling and safety
Any loudspeaker assembly must be modeled before installation so as to ensure acoustical and mechanical conformity.
This can be done using L-Acoustics
which will assist the user to:
• Determine the number of required Kara enclosures (acoustic data not available for subwoofers).
• Calculate the array site angle and the inter-enclosure angles.
• Check the mechanical conformity of the loudspeaker assembly.
The KARA-MINIBU/KARA-MINIBUEX structure can nominally y an array of up to 2 SB18/6 Kara or 4 SB18
along with all loudspeakers cables (refer to
(p.26)). However, this maximum number can
decrease in line with the array curvature.
Always refer to the mechanical data and warning indications provided in
(
Mechanical
Data
section) to verify the mechanical conformity of the loudspeaker assembly before installation.
The Kara, SB18, KARA-MINIBU, and KARA-MINIBUEX fully integrated rigging systems allow assembling the array with
no need for any external accessory.
The following rst procedure describes how to y a vertical SB18/Kara array using two KARA-MINIBU/KARA-MINIBUEX
rigging structures. It is recommended to assemble the Kara by successively adding arrays of 3 enclosures (called
ARRAY#1 and ARRAY#2 in the order of appearance in the procedure). The second procedure describes how to
disassemble the array.
Array mounting
About this task
All along the procedure:
Strictly follow the sequence of the successive steps.
Systematically verify that each BLP is fully inserted.
Systematically verify that the bolt is fully driven and secured by a safety pin on each shackle.
Systematically verify that each bolt is fully driven on the KARA-MINIBUEX.
For clarity purposes the loudspeaker cabling procedure will not be described.
The loudspeaker cables will not be represented on the gures.
Use a strain relief to avoid mechanical stress at the connector locations due to cable weight.
The motor hooks or stingers will not be represented on the gures.
Required tools
• electric screwdriver with torque selector
• 6 mm hex bit
• 13 mm hex key
