IMPORTANT SAFETY INSTRUCTIONS
WARNING!: Before placing, installing, rigging, or suspending any loudspeaker product, inspect all hardware, suspension,
cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated
component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the
safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions of
the installation and any possible short-term, unexpected overloading.
Never exceed the rating of the hardware or equipment.
Consult a licensed, professional engineer regarding physical equipment installation. Ensure that all local, state and national
regulations regarding the safety and operation of loudspeakers and related equipment are understood and adhered to.
Rigging Safety Regulations:
• 2006/42/EC
• EN ISO 12100-1: 2004
• EN1991-1 / EN1993-1-1 / EN1993-1-8 / EN1999-1-1
• DGUV Vorschrift 17/18
• ANSI E1.8-2018
General Rules for Suspension
• Consult a professional mechanical or structural engineer, licensed in the jurisdiction of the sound system installation, to review, verify,
and approve all attachments to the building or structure.
• Employ the services of a certified, professional rigger for hoisting, positioning, and attaching the equipment to the supporting
structure.
• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.
• Always calculate suspended loads before lifting to make sure suspension components and hardware are used within their respective
load limits.
• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which the equipment
will be suspended.
• Use only dedicated QSC LA108-AF and/or QSC LA112-AF Array Frames or the QSC LA-KIT-I installation kit (sold separately) for
suspending a loudspeaker array.
• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can
have hidden structural weakness.
• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the
loads.
• Before lifting, always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for
cracks, wear, deformation, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly. Discard any
worn, defective, or suspect parts and replace them with new, appropriately load-rated parts.

Attaching a Loudspeaker to the Array Frame
1. Hang both Front Strikes of the loudspeaker onto the Front Hooks of the Array Frame. (See —Figure5—)
2. Lift rear handles of the loudspeaker until the Angle Bar reaches the Array Frame. Secure the loudspeaker Angle Bars to the Array
Frame with the Array Frame Rigging Pins on both sides. (See —Figure6—)
WARNING!: Both rigging pins must be used to safely secure the loudspeaker to the array frame. Never use only one pin!

Pick-Point Deployments
Single Pick-Point Deployment
For single pick-point deployments, a 16 mm (5/8 inches) shackle (not included) can be attached
to the center rail of the Array Frame at the center-of-gravity (CG) point for the desired angle.
(See—Figure9—)
The tilt angle of the array can be adjusted by moving the pick-points
forward or backward. (See—Figure10—)

Dual Pick-Point Deployment
For a dual pick-point deployment with two pick-points, two 16 mm (5/8 inches) shackles (not
included) can be attached to the center rail of the Array Frame at the CG pointsfor the desired
angle. (See—Figure11—)
NOTE: EASE Focus 3 can be utilized to locate the CG point and desired vertical angle for
specific deployments. (EASE Focus 3 is available for free download from www.qsc.com.)
Optional Eyebolt
When a downtilt outside of the CG of the Array Frame is needed, an
M10 Eyebolt can be used on the rear of the lowest loudspeaker of the
array to provide another pick-point for further support to angle the system.
(See—Figure12—)
WARNING!: Do not exceed the Working Load Limits of the
M10Pullback Point as stated in the table below.

Ground Deployment
Stacking over a Subwoofer(s)
LA108/LA112 active line array loudspeakers offer the ability to safely stack an array over an
LS118/KS118 subwoofer(s) unit using the appropriate Array Frame and Sub Stack Adapter
Kit (sold separately).
WARNING!: When deploying loudspeakers on subwoofers, attention should be
given to environmental conditions such as level surfaces, vibrations, wind, etc. to
deploy the loudspeakers in a stable and safe manner. Use additional measures to
secure the subwoofer (hardware not included with subwoofer) when necessary.
LA108
An array of up to four (4) LA108 loudspeakers can be stacked over one (1) LS118/KS118
subwoofer when the subwoofer is upright, or two (2) LS118/KS212C subwoofers when
rotated on their side.
L A 112
An array of up to three (3) LA112 loudspeakers can be stacked over one (1) or two (2) LS118/KS212C when the subwoofers are
rotated on their side.
NOTE: For these ground-stack deployments, the LA108-AF (Array Frame) and the LA108-KIT-SA (Stack Adapter Kit) accessories
(sold separately), or the LA112-AF (Array Frame) and the LA112-KIT-SA (Stack Adapter Kit) accessories (sold separately) are
needed on the top (LS118/KS118/KS212C) or side (LS118/KS212C) of the subwoofer to secure the array. These combined
accessories bolt onto the M20 thread located on the top or side of the subwoofer (LS118/KS212C) to secure the array. See next
section for proper deployment of these two accessories, please refer to the individual accessories' user manuals.
Attaching an Array Frame and Stack Adapter Kit to a Subwoofer
See —Figure14— for steps 1 to 4.
1. Carefully remove paper backing from the adhesive sides of the Bumper Pads. Adhere Bumper Pads to the bottom of the Array Frame
as shown.
2. Secure the Tie-Down Assembly to the M20 thread located on top, or side, of the subwoofer enclosure. Tighten screw with fingers
until snug. If necessary, tighten further using a coin, a key, or a large screwdriver.
3. Place Array Frame on subwoofer with the Bumper Pads facing downward.
4. Use the Tie-Down Knob to secure the Array Frame to the Tie-Down Assembly. Tighten the knob with your hand until snug. Array
Frame is now secured to the subwoofer.
