Rigging KLA Series Loudspeakers

WARNING!: 

Read and follow these instructions carefully. If the loudspeakers are not suspended properly, they could fall, 

causing personal injury and damage to the equipment.

 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 certifi ed, 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 you will suspend 

the equipment.

•  Use only the KLA AF12 Array Frame or the M10 installation points for suspending the 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.

Shock Loading

When a load is either moved or stopped, its static weight is magnifi ed. Sudden movements can magnify the static weight several times. This 

magnifi cation of static weight is called "shock loading". Shock loading poses a danger to equipment and workers. The effects of shock loading can be 

instantaneous, or may remain undetected unless the equipment is visually damaged. Proper preparation for shock loading requires careful planning 

and knowledge of equipment, suspension, and lifting practices.

Shock loading of equipment and structures is usually confi ned to lifting and installation, but natural forces (winds, earthquakes, and so on) can impose 

shock loads several times the static load. Because of this, structures and suspension equipment must be capable of supporting several times the 

weight of the suspended equipment.

 KLA Maximum Suspended Load

The KLA components are engineered for a 10:1 design factor. Use a KLA 

AF12 Array Frame or the M10 Integrated Suspension points to suspend one 

KLA Array consisting of one of the following array confi guration options. 

The maximum number of KLA12 Loudspeakers in any array, with or without 

KLA181 Loudspeakers, is fi ve.
