7. System parts and rigging inspection
All system components must be inspected before use, in order to detect any possible defects.
Please refer to the “Care and maintenance” section of this manual as well as any other manuals
pertaining to the system for a detailed description of the inspection procedure.
Any part showing any sign of defect must immediately be put aside and withdrawn from use to be
inspected by qualified service personnel.
8. Additional rigging equipment
L-ACOUSTICS®is not responsible for any rigging equipment and accessories that are not
manufactured by L-ACOUSTICS®.
It is the user’s responsibility to ensure that the Working Load Limit (WLL) of all additional
hardware rigging accessories is greater than the total weight of the loudspeaker assembly in use.
9. Suspension points
It is the user’s responsibility to ensure that the Working Load Limit (WLL) of the suspension
points and/or chain hoists is greater than the total weight of the loudspeaker assembly in use.
10. System load capacity and setup safety limits
Load capacity and setup safety limits when flying or stacking a loudspeaker assembly should be
strictly followed according to the instructions outlined in this manual.
Always refer to the mechanical data and warning indications provided in SOUNDVISION to
verify that safe system setup safety limits apply.
11. Local regulations
Some countries require higher Ultimate Strength Safety Factors and specific rigging approvals. It
is the user responsibility to ensure that any overhead suspension of L-ACOUSTICS®systems
has been made in accordance with all applicable local regulations.
As a general rule, L-ACOUSTICS®recommends the use of safety steel at all times.
12. Flying a loudspeaker assembly
Always ensure that nobody is standing underneath the loudspeaker assembly when it is being
raised. As the system is being raised check each individual component to make sure that it is
securely fastened to the component above. Never leave the system unattended during the
installation process.
13. Ground stacking a loudspeaker assembly
Do not ground stack the system on uneven ground or platform.
If the system is ground stacked on a structure, platform, or stage always check that it can
support the total weight of the system.
Secure the system to the structure, platform, or stage using ratchet straps or any other
applicable devices.
14. Dynamic load
When a loudspeaker assembly is deployed in an open air environment wind effect should be
taken into account. Wind can produce dynamic stress to the rigging components and suspension
points. If the wind force exceeds 6 bft. (Beaufort scale) it is highly recommended to lower down
and/or secure the loudspeaker assembly.

4KUDO®SYSTEM
The L-ACOUSTICS®KBUMP structure and the KLIFT and KJACK accessories are dedicated to fly and stack the
KUDO®system.
The system approach developed by L-ACOUSTICS®for KUDO®comprises the elements needed to fully take
advantage of the possible configurations and optimize the system. The main components of the system are:
KUDO® Full range active 3-way loudspeaker enclosure
KBUMP  Rigging structure to fly or stack a KUDO®array in the vertical orientation
KJACK  Rigging accessories (x2) used in conjunction with KBUMP to stack KUDO®
KLIFT  Rigging accessory to fly a KUDO®array in the horizontal orientation
KPLA-2, KCOV  Removable front dolly board and protective cover to ship the KUDO®
SB118, SB28  Subwoofer enclosures for extended low frequency response
LA8  Dedicated amplified controller
SOUNDVISION  Acoustical and mechanical modeling software
LA NETWORK MANAGER  Remote control software
Figure 2: KUDO®system components
Each system configuration should first be modeled using the L-ACOUSTICS®SOUNDVISION software to verify
that safe system setup safety limits apply. A detailed description on the use of the SOUNDVISION software is beyond
the scope of this manual. Please refer to the appropriate documentation, also available on the L-ACOUSTICS®internet

5KUDO®RIGGING COMPONENTS
5.1 KBUMP rigging structure and KJACK rigging accessories
The L-ACOUSTICS®KBUMP rigging structure has been exclusively designed to fly or stack the L-ACOUSTICS®
KUDO®enclosures as a variable-curvature, vertical line source array.
Figure 3: KBUMP with two shackles
The KBUMP is supplied with two 22-shackles (Figure 3) that can support up to 2000 kg / 4409 lb. each with an Ultimate
Strength Safety Factor of 5:1. Thirteen pick up points are available on the central spreader bar section and side bars
allowing for a wide variety of hoist set up. Please refer to appendix 9.1 for a detailed description of the KBUMP rigging
options examples.
KBUMP can fly a maximum amount of weight of 1830 kg / 4034 lb.
Therefore, a maximum of 21 KUDO®enclosures can be flown underneath the KBUMP rigging
structure without any additional load.
Always refer to the mechanical data and warning indications provided in SOUNDVISION to verify
that safe system setup safety limits apply (see section ‘‘Mechanical Data’’ in the SOUNDVISION
software).

Figure 4: KBUMP and KJACK elements for stacking a KUDO®array
KBUMP can also be used as a horizontal or tilted ground stacking platform using two complimentary KJACK accessories
(Figure 4).
A maximum of 6 KUDO®can be stacked onto a horizontally configured KBUMP (site angle set at 0°).
When KBUMP is used with the complimentary KJACK accessories so as to form a tilted platform, the
following limitations apply:

Ensure that KBUMP is physically secured to the stacking platform or subwoofer stack using ratchet
straps or any applicable materials.

5.2 KLIFT rigging accessory
The L-ACOUSTICS®KLIFT rigging accessory has been exclusively designed to fly the L-ACOUSTICS®KUDO®
enclosures as a 10°-constant curvature, horizontal line source array.
The KLIFT is supplied with one 18-shackle (Figure 5) that can support up to 1250 kg / 2756 lb. with an Ultimate
Strength Safety Factor of 5:1. Twelve pick up points are available on the KLIFT to set the site angle. Please refer to
appendix 9.2 for a detailed description of the KLIFT available configurations.
Figure 5: KLIFT rigging accessory with shackle
One or more KLIFT accessories can fly horizontal arrays composed of a minimum of 2 KUDO®enclosures. Figure 6
shows six examples of single or dual suspension point arrays: it can be seen that only symmetrical configurations are
available in order to properly balance the array’s center of gravity.
A single KLIFT can support a maximum amount of weight of 522 kg / 1150 lb. and can therefore
support up to 6 KUDO®enclosures without any additional load.
Any configuration containing one or more KLIFT accessories should be prior modeled using
SOUNDVISION software.
Always refer to the mechanical data and warning indications provided in SOUNDVISION to verify
that safe system setup safety limits apply (see section ‘‘Mechanical Data’’ in the SOUNDVISION
software).

6INSTALLATION
6.1 Flying a vertical line source array (using KBUMP)
Before installation, in order to position and correctly place the array the user should use L-ACOUSTICS®
SOUNDVISION software to determine:
•Correct hole position of the shackles on the KBUMP
•Number of KUDO®enclosures
•Inter-angles between KUDO®enclosures
•Check of the system’s mechanical conformity
Always refer to the mechanical data and warning indications provided in SOUNDVISION to verify
that safe system setup safety limits apply (see section ‘‘Mechanical Data’’ in the SOUNDVISION
software).
The rigging method to fly the KUDO®system comprises the elements KBUMP and KUDO®. Attaching one element to
the next is done by using fully integrated components unique to each KUDO®. There is no need for any other external
fastening accessory. Each KUDO®enclosure incorporates two rotating arms that lock into the device above, and four
rigging points that lock into the device below, using ball locking pins (BLP).
The following procedures describe how to fly a vertical KUDO®line source array, and how to disassemble it.
6.1.1 Assembling the KUDO®enclosures and the KBUMP structure
All along the following procedure systematically ensure that each BLP is correctly secured by pulling
on it, and that screw pin is correctly secured on each shackle anchor.
1. Line up the KBUMP structure and all KUDO®enclosures at the rigging location.

8. On the KBUMP structure, ensure that the 4 BLP are located in their inner storage holes.
9. a. Place the KBUMP in position by aligning both stop tabs with the top KUDO®enclosure’s front rigging points.
The KBUMP should be installed with the serial number tag oriented towards the
rear of the array.
Support the KBUMP in order to prevent it from falling.
b. Attach the 4 BLP in the outer storage holes so as to secure the KBUMP to the top KUDO®enclosure.
10. Attach the 22-shackles according to the specifications detailed in appendix 9.1.
