Rigging proceduresFlying an SB18/Kara mixed array or an SB18 standalone arrayUsing M-BUMPModeling and safetyAny system must be modeled before installation so as to ensure acoustical and mechanical conformity. This can be doneusing L-Acoustics Soundvision Software which will assist the user to:• Determine the number of required Kara enclosures.• Calculate the array site angle and the inter-enclosure angles.• Check the mechanical conformity of the system.The M-BUMP can nominally y an array of up to 4 SB18/12 Kara or 16 SB18 along with all loudspeakers cables(refer to Mechanical safety (p.26)). However, this maximum number can decrease in line with the array curvatureand/or the acoustic coupling conditions (depending on the selected operation mode as described in the KaraUser manual).ALWAYS refer to the mechanical data and warning indications provided in Soundvision Software (MechanicalData section) to verify the mechanical conformity of the system before installation.The Kara, SB18 and M-BUMP fully integrated rigging systems allow assembling the array with no need for any externalaccessory.The following rst procedure describes how to y a vertical SB18/Kara array using two M-BUMP. According to the arraycomposition, the SB18 enclosures can be rigged one by one or by pairs (as shown in the procedure). It is recommendedto rig the Kara by successively adding arrays of 3 enclosures (called ARRAY#1, ARRAY#2… in the order of appearancein the procedure). The second procedure describes how to disassemble the array.Array mountingAbout this taskAll 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.Procedure1. Place an M-BUMP at the rigging location. Turn it so that the text of the identication plate is readable and the laserslits are directed towards the audience.Kara owner's manual (EN) version 1.0 69
