Rigging procedures
Using KARA-MINIBU
Modeling and safety
An SB18/Kara mixed array or an SB18 standalone array must be stacked directly on the ground (ground stacked array).
Any SB18/Kara ground stacked array must be modeled before installation so as to ensure acoustical conformity. This can
which will assist the user to:
• Determine the number of required Kara enclosures (acoustic data not available for subwoofers).
• Calculate the inter-enclosure angles.
A ground stacked array must be installed on a perfectly horizontal and regular surface. It can be composed of
a maximum of 4 SB18/6 Kara or 8 SB18 within the setup safety limits given in Table 3 regarding the angle
between the top SB18 and the bottom Kara (refer to [9.3.2] for angle settings):

(p.122).
SB18 standalone array assembling procedure:
Stack a rst SB18 on the ground, front face logo down. Stack a
second SB18 onto the rst one and attach it by applying step
(p.81). Repeat the procedure until all SB18 composing
the array are assembled.
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 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.
Required tools
• electric screwdriver with torque selector
• 6 mm hex bit6 mm hex bit
• 13 mm hex key
Procedure
1.
Bring a rst SB18 (SB18#1) to the rigging location, remove the dolly board, and stack it on the ground logo up.
Orient all SB18 composing the array towards the audience to obtain an omnidirectional acoustic pattern
or turn one SB18 out of four from front to rear to obtain a cardioid acoustic pattern (refer to the
). As an example, the following gures show a cardioid SB18 array.
2.
In the same way, stack a second SB18 (SB18#2) onto SB18#1.
3.
Attach SB18#2 to SB18#1 as follows:
a) Remove a T-BLP from SB18#2.
b) Rotate the link arm down.
