ALK-MD3 Array Link Kit for Three MD-series Loudspeaker Enclosures
This kit is to be used only for arraying of three vertically oriented QSC MD series loudspeaker enclosures, active or passive. Do not use this kit or any component of this kit for any other purpose. [. . . ] · Employ the services of a professional rigger for hoisting, positioning, and attaching the equipment to the supporting structure. · 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 before lifting. 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. This magnification of static weight is termed "shock loading". The effects of shock loading can be instantaneous, or they may remain undetected unless the equipment is visually damaged. Avoiding shock loading requires careful planning and knowledge of equipment, rigging, and lifting practices. · Shock loading of equipment and structures is usually confined to lifting and installation, but natural forces (winds, earthquakes) can impose shock loads several times the static load. This is why structures and suspension equipment must be capable of supporting several times the weight of the equipment suspended.

Installation Instructions
1. Orient the enclosures with their bottoms pointing upward and the required splay angle. Remove the factory-installed screws from the enclosures where the bolts are to be installed for the ALK-MD3 kit. Set the rear (AL-MD3) and front ( AL-MDF) links on the enclosures and position the assembly until the mounting holes line up at the required splay angle. Put the bolt assembly through the selected mounting hole in the array link and thread the bolt into the enclosure's threaded insert. [. . . ] Note eyebolt installation locations.
