Patent and Trademark Office 2 Introduction The WL218-sw is a dual 18-inch (457mm) subwoofer designed for suspended or ground stacked use in touring or installed concert applications. [. . . ] ·Always calculate suspended loads before lifting to ensure suspension components and hardware are used within their respective load limits. ·Research local codes and regulations to fully understand the requirements for suspended loads in the venue in which the equipment is to be suspended. ·Be absolutely certain of the integrity of any structural member intended to support suspended loads. ·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. ·Never assume anything- Owner or third-party supplied suspension attachment points may not be adequate for the loads to be suspended. ·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. WideLine Working Load Limits and Design Factors Table 1 lists the WideLine suspension components and provides Working Load Limit data at various Design Factors. The choice of which Design Factor to use will depend upon the jurisdiction and venue of installation, as well as the conditions of suspension. Dynamic conditions are determined by unknown, installation-specific factors and should be referred to a Licensed Structural Engineer for clarification before proceeding with any suspension of the equipment. The data presented is based upon the listed component weights: Table 1: WideLine WL218-sw System Working Load Limits Component WL218-sw Loudspeaker AF218-sw Array Frame 1/2-inch Shoulder Bolt1 5/16-inch Ball Lock Pin1 1/2-inch Ball Lock Pin1 Weight 206 lb (93. 4 kg) 80 lb (36. 3 kg) n/a n/a n/a 5:1 Design Factor 3400 lb(1540 kg) 3400 lb(1540 kg) 6400 lb (2900 kg) 2400 lb (1090 kg) 6400 lb (2900 kg) 7:1 Design Factor 2400 lb (1090 kg) 2400 lb (1090 kg) 4500 lb (2040 kg) 1700 lb (771 kg) 4500 lb (2040 kg) 10:1 Design Factor 1700 lb (771 kg) 1700 lb (771 kg) 3200 lb (1450 kg) 1200 lb (544 kg) 3200 lb (1450 kg) 1- Working Load Limits are per fastener loaded in double shear.

Front Articulated Joint1- Remove the ball lock pin. 2- Slide the articulated joint out of the receiver tube by lifting its retaining screw upward. 3- Lock in place using the ball lock pin. 1 Attaching WL218-sw Loudspeaker to WL218-sw Loudspeaker 1- With the enclosures on dolly boards and facing downward, position two enclosures adjacent one another such that the front receiver tubes are aligned. Align and insert the articulated joint into the upper enclosure's receiver tube. Pin each articulated joint in place using two ball lock pins, one at each end inserted fully and locked in position. Failure to follow these recommendations may result in dangerous conditions, injury, or death! [. . . ] SEE WARNINGS IN THE Note pin numbers 2+ and 2- are wired straight through from one connector to the other. This accommodates using one input cable assembly (where appropriate) for subwoofer and full range loudspeaker connections. Additionally, pin numbers 1+ and 1- of both NL4s are wired in parallel. All signal processing must be done before connecting audio power to the loudspeaker.
