INSTALLATIONINSTALLATION

6.1 Flying a KARA standalone array

6.1.1 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® SOUNDVISION Software [3.4] 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 and KARA-MINIBU fully integrated rigging systems allow assembling the array with no need for any external accessory.

The following first procedure describes how to fly 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.

6.1.2 Array assembling procedure

1. Bring a full KARA flight-case to the rigging location and remove the lid. Direct the front face of the KARA array

2. Check the inter-enclosure attachments in ARRAY#1 as follows (repeat on both sides of the array):

The KARA-MINIBU can nominally fly an array of up to 6 KARA along with all loudspeaker cables (refer to the KARA User manual [3.4]). However, this maximum number can decrease in line with the array curvature.

ALWAYS refer to the mechanical data and warning indications provided in SOUNDVISION software (Mechanical Data section) to verify the mechanical conformity of the loudspeaker assembly before installation.

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.

For clarity purposes the loudspeaker cabling procedure will not be described.

The loudspeaker cables will not be represented in the figures.

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 in the figures.

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.

a. Verify that each front arm (x2) is open and secured to the link holes of two KARA by two R-BLP. Note: 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°.

3. Open the four KARA#1 arms as follows (repeat on both sides of the enclosure): a. Remove the front top R-BLP from its storage hole, rotate the front arm up, slide it down, and lock it in place

by re-inserting the R-BLP into its link hole. Note: The front top storage and link holes are the same.

b. Remove the rear top R-BLP from its storage hole, slide the angle arm so as to align the cursor with angle

label 5°, and lock it in place by re-inserting the R-BLP into angle hole 1°/3°/5°/7.5°/10°.

It is recommended to select the 5° angle on the KARA intended to be attached to the KARAMINIBU; in that way the KARA#1 axis will be parallel to the KARA-MINIBU.

6.2 Flying a SB18/KARA mixed array or a SB18 standalone array

6.2.1 Modeling and safety

• 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 fly an array of up to 2 SB18/6 KARA or 4 SB18 along with all loudspeakers cables (refer to the KARA and SB18 User manuals [3.4]). However,

this maximum number can decrease in line with the array curvature.

NEVER assemble an array containing an M-BUMP on top and a KARA-MINIBU/KARA-MINIBUEX between SB18 and KARA for mechanical stress purposes (refer to the KARA Rigging procedures pack [3.4] for M-BUMP description).

On the contrary, it is possible to assemble an array containing a KARA-MINIBU/KARA-MINIBUEX on top and an M-BUMP between SB18 and KARA. In such a case, select the KARA-MINIBU/KARA-MINIBUEX structure in SOUNDVISION to verify the mechanical conformity of the loudspeaker assembly.

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 first procedure describes how to fly a vertical SB18/KARA array using two KARA-MINIBU/KARAMINIBUEX rigging structures. It is recommended to assemble the KARA by successively adding arrays of 3 enclosures (called ARRAY#1, ARRAY#2 in the order of appearance in the procedure). The second procedure describes how to disassemble the array.

6.2.2 Array assembling procedure

For clarity purposes the loudspeaker cabling procedure will not be described. The loudspeaker cables will not be represented in the figures. 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 in the figures.

Required tools

Electric screwdriver with torque selector (N.m or in.lbf), 6 mm hex bit, 13 mm hex key.

Procedure

1. Assemble a KARA-MINIBU/KARA-MINIBUEX rigging structure as follows: a. Turn the KARA-MINIBU so that the text of the identification plate is readable. b. Position a first KARA-MINIBUEX on the laser plate side of the KARA-MINIBU by turning it feet pointing up

and inserting the stud into the slit of the KARA-MINIBU located near the laser plate.

c. Drive 3 bolts into the 3 holes shown in Figure 21 (6 mm hex bit, 13 mm hex key, 7 N.m/63 in.lb d. Repeat the procedure with a second KARA-MINIBUEX on the other side of the KARA-MINIBU.

e. Attach the shackle(s) to the KARA-MINIBU [9.4] according to the chosen configuration [9.2]. Note: If the

array is intended to be flown in pullback configuration, attach a single shackle to the rear pullback hole [5.1].

6.3 Stacking a KARA standalone array

6.3.1 Modeling and safety

A KARA array must be stacked onto a KARA-MINIBU/KARA-MINIBUEX platform (platform stacked array).

Any platform stacked array must be modeled before installation so as to ensure acoustical conformity. This can be done using L-ACOUSTICS® SOUNDVISION Software [3.4] which will assist the user to:

• Determine the number of required KARA enclosures.

• Calculate the inter-enclosure angles.

A platform stacked array requires to be installed on a perfectly horizontal and regular surface. It can be composed of a maximum of 6 KARA enclosures along with all loudspeaker cables (refer to the KARA User manual [3.4]) within the following setup safety limits:

• If the KARA array is flat (all inter-enclosure angles are close to 0°), the platform must be installed in

front extension configuration (refer to [9.3.1]) and the site angle of the bottom KARA must be set

within the range given in Table 2 (refer to [9.3.2] for angle settings):

Table 2: Platform stacked KARA array safe configurations

Number of KARA Bottom KARA authorized angle range

1 - 3 From -15° to +5°

4 From -11° to +5°

5 - 6 From -7.5° to +5°

• If the KARA array is strongly curved (all inter-enclosure angles are close to 10°), the platform must be

installed in rear extension configuration (refer to [9.3.1]).

The KARA, KARA-MINIBU, and KARA-MINIBUEX fully integrated rigging systems allow assembling the array with no need for any external accessory. The following first procedure describes how to assemble a vertical KARA platform

stacked array. The second procedure describes how to disassemble the array.

6.3.2 Array assembling procedure

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 in the figures.

Required tools

Electric screwdriver with torque selector (N.m or in.lbf), 6 mm hex bit, 13 mm hex key.

Procedure

1. Assemble a KARA-MINIBU/KARA-MINIBUEX stacking platform as follows: a. Turn the KARA-MINIBU so that the text of the identification plate is upside down. b. Position a first KARA-MINIBUEX on the laser plate side of the KARA-MINIBU by turning the KARA-

6.4 Stacking a SB18/KARA mixed array or a SB18 standalone array

6.4.1 Modeling and safety

A SB18/KARA mixed array or a 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 be done using L-ACOUSTICS® SOUNDVISION Software [3.4] which will assist the user to:

• Determine the number of required KARA enclosures (acoustic data not available for subwoofers).

• Calculate the inter-enclosure angles.

SB18/KARA mixed array assembling procedure: Apply [6.4.2].

SB18 standalone array assembling procedure: Stack a first SB18 on the ground, front face logo down. Stack a second SB18 onto the first one and attach it by applying [6.2.2, step 2c]. Repeat the procedure until all SB18 composing the array are assembled. While installing, follow the IMPORTANT indication given below.

6.4.2 Array assembling procedure

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 enclosures 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):

Table 3: Ground stacked SB18/KARA array safe configurations

Number of SB18 Number of KARA Bottom KARA authorized angle range

1 - 2 From -15° to +5°

3 From -5° to +5° 1

4 - 6 From -4° to +5°

3 - 4 1 - 6 From -15° to +5°

1 - 5 From -15° to +5°

6 From -12° to +5°

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 in the figures.

Required tools

Electric screwdriver with torque selector (N.m or in.lbf), 6 mm hex bit, 13 mm hex key.

Procedure

1. Bring a first SB18 (SB18#1) to the rigging location, remove the dolly board, and stack it on the ground logo up.

Turn the front faces of all SB18 composing the array towards the audience to obtain an

omnidirectional acoustic pattern or turn one SB18 every fourth from front to rear to obtain a cardioid acoustic pattern (refer to the SB18 User manual [3.4]).

2. In the same way, stack a second SB18 (SB18#2) onto SB18#1.

9.2.2 KARA-MINIBU site angle setting

The KARA-MINIBU site angle setting will be discrete or continuous depending on the chosen rigging option.

Rigging options 1 and 3 offer 17 discrete site angle values in each configuration by selecting the single shackle position (holes 1-17). The hole numbering convention is shown in Figure 67 for KARA-MINIBU and Figure 68 for KARAMINIBU/KARA-MINIBUEX.

For rigging options 1 and 3 the bumper site angle will also depend on the size and shape of the array (number of enclosures and inter-enclosure angles). Refer to SOUNDVISION Software [3.4] for site angle calculation.

Note: Hole 15 provides 0° site angle for an SB18 standalone array.
