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.
• Calculate the KARA-MINIBU site angle and the inter-enclosure angles.
• Check the mechanical conformity of the loudspeaker assembly.
The KARA-MINIBU can nominally y an array of up to 6 Kara along with all loudspeaker 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 and KARA-MINIBU 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 Kara array under a KARA-MINIBU. 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 screwed in and secured with safety pin on each shackle.
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.
Procedure
1.
Bring a full Kara ight-case to the rigging location and remove the lid. Direct the front face of the Kara array towards
the audience. In the following, the array will be designated as ARRAY#1 and the enclosures as KARA#1 to KARA#3
from top to bottom.
2.
Check the inter-enclosure attachments in ARRAY#1 as follows (repeat on both sides of the array):
a) Verify that each front arm (x2) is open and secured to the
link
holes of two Kara by two R-BLP.
A
link
hole is indicated by a yellow circle.
b) Verify that each angle arm (x2) has the cursor aligned with the 0° angle label and is secured to two Kara by two
R-BLP, the top one being inserted into the
link
hole and the bottom one into angle hole 0°/2°/4°.
