Safety
Safety
Instructions
Inspect the system before any deployment.
Perform safety related checks and inspections before any deployment.
Perform preventive maintenance at least once a year.
Refer to the preventive maintenance section for a list of actions and their periodicity.
Insufcient upkeep of the product can void the warranty.
If any safety issue is detected during inspection, do not use the product before performing
corrective maintenance.
Check for issues. A rigging system part or fastener is missing or loose. A rigging system part exhibits: bends,
breaks, broken parts, corrosion, cracks, cracks in welded joints, deformation, denting, wear, holes. A safety cue
or label is missing. A loose part is not adequately secured.
Never incorporate equipment or accessories not approved by L-Acoustics.
Read all the related PRODUCT INFORMATION documents shipped with the products before
exploiting the system.
Do not store the product on an unstable cart, stand, tripod, bracket, or table.
Beware of sound levels.
Do not stay within close proximity of loudspeakers in operation.
Loudspeaker systems are capable of producing very high sound pressure levels (SPL) which can instantaneously
lead to permanent hearing damage to performers, production crew and audience members. Hearing damage
can also occur at moderate level with prolonged exposure to sound.
Check the applicable laws and regulations relating to maximum sound levels and exposure times.
Work with qualied personnel for rigging the system
Installation should only be carried out by qualied personnel that are familiar with the rigging techniques and
safety recommendations outlined in this manual.
Ensure personnel health and safety
During installation and set-up personnel must wear protective headgear and footwear at all times. Under no
circumstances is personnel allowed to climb on a loudspeaker assembly.
Respect the Working Load Limit (WLL) of third party equipment.
L-Acoustics is not responsible for any rigging equipment and accessories provided by third party manufacturers.
Verify that the Working Load Limit (WLL) of the suspension points, chain hoists and all additional hardware
rigging accessories is respected.
Respect the maximum congurations and the recommended safety precautions.
For safety issue, respect the maximum congurations outlined in this manual. To check the conformity of
any conguration in regards with the safety precautions recommended by L-Acoustics, model the system in
Soundvision and refer to the warnings in Mechanical Data section.
Be cautious when ying a loudspeaker conguration.
Before installing/raising the product, check each individual element to make sure that it is securely fastened to the
adjacent element. Always verify that no one is standing underneath the product when it is being installed/raised.
Never leave the product unattended during the installation process.
As a general rule, L-Acoustics recommends the use of secondary safety at all times.
Be cautious when ground-stacking a loudspeaker array.
Do not stack the loudspeaker array on unstable ground or surface. If the array is stacked on a structure, platform,
or stage, always check that the latter can support the total weight of the array.
As a general rule, L-Acoustics recommends the use of safety straps at all times.

Safety
Risk of falling objects
Verify that no unattached items remain on the product or assembly.
Risk of tipping
Remove all rigging accessories before transporting a product or an assembly.
Take into account the wind effects on dynamic load.
When a loudspeaker assembly is deployed in an open air environment, wind can produce dynamic stress to the
rigging components and suspension points.
If the wind force exceeds 6 bft (Beaufort scale), lower down and/or secure the product or the assembly.
Intended use
This system is intended for use by trained personnel for professional applications.
As part of a continuous evolution of techniques and standards, L-Acoustics reserves the right
to change the specications of its products and the content of its documents without prior
notice.

Introduction
Introduction
K3i long throw line source for install
K3i is the installation version of K3, designed for long-throw installation applications. K3i shares identical sonic
performance with its touring counterpart but features a sleeker design and streamlined mounting hardware tting
integration requirements.
Housing the internationally recognized K2 performance into a compact enclosure, K3i is ideal for medium to large-scale
venues that require premium-tour sound and limited footprint, such as large concert halls, clubs, congress centers and
sport venues.
Inter-element angles and Panex™ for user-adjustable horizontal directivity enable integrators, consultants and sound
designers to precisely tailor the array coverage to any audience geometry.
Requiring only two channels of amplication, K3i is a high value solution that provides large-format concert sound in
compact and lightweight construction to facilitate most integration scenarios. K3i is highly weather-resistant as standard
and can be color-matched to melt into any venue decor, indoor or outdoor.
How to use this manual
The K3i owner's manual is intended for all actors involved in the system design, implementation, preventive and
corrective maintenance of the K3i system. It must be used as follows:
1. Read the technical description for an overview of all system elements, their features, and their compatibilities.
•Electro-acoustical description (p.11)
•Rigging system description (p.17)
2. Prepare the system conguration. Consider the mechanical limits and the available acoustical congurations.
•Mechanical safety (p.30)
•Loudspeaker congurations (p.32)
3. Before rigging the system, perform mandatory inspections and functional checks.
4. To deploy the system, follow the step-by-step rigging instructions and refer to the cabling schemes.
•Rigging procedures (p.37)
•Connection to LA amplied controllers (p.63)
