Quick Start Guide
Suspending the KLA12
WARNRNG!: 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 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 magnified. Sudden movements can magnify the static weight several times. This
magnification 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 confined 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 Working Load Limits
The KLA components are engineered for a 10:1 design factor.
Use the KLA AF12 Array Frame or the M10 Integrated Suspension points to suspend a single KLA Array consisting of a maximum of two KLA181, or five
KLA12, or two KLA181 and five KLA12 loudspeakers. The weight of any single array shall not exceed 480 lbs. (218 kg).
