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.
Insufcient 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 qualied personnel for rigging the system
Installation should only be carried out by qualied 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 congurations and the recommended safety precautions.
For safety issue, respect the maximum congurations outlined in this manual. To check the conformity of
any conguration 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 conguration.
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.
A10i owner's manual (EN) version 1.0 5

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 specications of its products and the content of its documents without prior
notice.
Check www.l-acoustics.com on a regular basis to download the latest document and software updates.
Do not expose the product to extreme conditions.
Do not expose the product to moisture (rain, mist, sea spray, steam, humidity, condensation…) or excessive heat
(direct sun, radiator…) for a long period of time.
For more information, refer to the Product protection ratings document, available on the website.
Read the maintenance section of this document before servicing the product.
Contact L-Acoustics for advanced maintenance.
Any unauthorized maintenance operation will void the product warranty.

Introduction
Introduction
A10i family
Part of the A Series, A10i is a medium throw product line designed for installation applications up to 35 m. The highly
multifunctional family includes A10i Focus and A10i Wide, passive 10'' systems with distinct coverage patterns. A10i
products can be own or stacked in combinations to form vertical or horizontal line sources or used individually as
congurable directivity point sources.
A10i can adapt to virtually any audience geometry with two enclosure coverage options (10° or 30°), Panex for user
adjustable waveguide directivity (70°, 110° or 90° asymmetrical) and a range of accessories for vertical or horizontal
deployment.
A10i deployment requires a single preset that is optimized to provide amazing plug-and-play performance for both A10i
models regardless of Panex conguration. Performance can be further enhanced with L-Acoustics software optimization
tools.
On its own A10i provides ideal bandwidth for vocal reinforcement or music with light LF requirements and produces an
exceptional SPL-to-size ratio to complement a larger system as lls. The acoustically compatible subwoofer KS21i can be
associated with A10i to extend the frequency bandwidth and reinforce the low-frequency contour.
The compact and lightweight A10i is an ideal solution as mains or ll systems for integration applications that require
intelligibility and aesthetics.

Electro-acoustical description
Adjustable ns
A10i Focus and A10i Wide feature L-Fins to adjust the waveguide directivity to one of four settings: 110° / 70°
symmetric or 90° asymmetric (35°/55° or 55°/35°).
The same [A10] preset drives all directivity settings of both enclosures.
Within a line source, combine A10i Focus and A10i Wide with custom directivity settings to improve SPL mapping and
throw capability.
