[. . . ] 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 suspension equipment are understood and adhered to. Warranty (USA only; other countries, see your dealer or distributor) Disclaimer QSC Audio Products, LLC is not liable for any damage to amplifiers or any other equipment that is caused by negligence or improper installation and/ or use of this loudspeaker product. QSC Audio Products 3-Year Limited Warranty QSC Audio Products, LLC ("QSC") guarantees its products to be free from defective material and/or workmanship and will replace defective parts and repair malfunctioning products under this warranty when the defect occurs under normal installation and use-provided the unit is returned to our factory, one of our authorized service stations or an authorized QSC International Distributor via pre-paid transportation with a copy of proof of purchase (i. e. , sales receipt). This warranty provides that the examination of the return product must indicate, in our judgment, a manufacturing defect. [. . . ] EASE Focus can calculate the number of enclosures required for a given space (venue), determine the optimum splay angle between those enclosures, calculate at what angle to set the array frame in a single (variable) pick-point or fixed suspension point application, and predict the acoustical response and sound pressure levels throughout the venue in a two-dimensional illustration. The software may be downloaded from the QSC website. Like all QSC products, WideLine-10 design focuses on accurate audio performance, rapid set-up, and reduced labor requirements. Ease of transportation, assembly, use, and self contained rigging hardware make WideLine-10 the clear choice. Front (grille removed) 1.

Connect the full-range input signal to pins 1+ and 1-, connect the shaded (processed) signal to pins 2+ and 2-. To flip shaded transducer location, use the mF (UNSHADED) SELECT switch or alter signal processing. Default mF (UNSHADED) SELECT switch position for three way mode is position A; if put in position B, connections (Table 1) to LF transducers A and B are interchanged. · 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. Sudden movements can magnify the static weight several times. This magnification of static weight is termed "shock loading". Shock loading poses a danger to equipment and workers. 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-10 Working Load Limits and Design Factors The following chart (Table 2) provides Working Load Limit data at various Design Factors. The tabulated Design Factors are for static loads only. [. . . ] This frame will easily sit on ground stacked bass enclosures or it can be used to suspend smaller arrays from the stage trusses. AF2102-LA Use only the QSC supplied 5/16" diameter x 1. 25" long ball-lock pins or equivalents from a reputable source on front receiver tubes. The three pick up rails allow for any number of rigging solutions to fit the most demanding venues. The rails are drilled for industry standard 5/8" shackles. Do not stack more than eight (8) enclosures on the AF2102-LA Frame. 31. 6" (803 mm) Bolt on receiver tube and 5/16" diameter, 1. 25" long ball-lock pin. 14. 8" (376 mm) 37. 0" (940 mm) Left pickup rail Center pickup rail Right pickup rail Front 7 AF2102-LA The link arm is located on the bottom side of the frame assembly.
