[. . . ] To obtain the most recent version of QSC's warranty statement, please visit www. qscaudio. com. The QSC limited warranty is valid for a period of three (3) years from date of purchase in the United States and many (but not all) other countries. For QSC warranty information in countries other than the United States, contact your authorized QSC international distributor. A list of QSC International distributors is available at www. qscaudio. com. [. . . ] With selectable shading, the enclosures can be used as house right or left by flipping the switch, not the enclosure. WideLine-10 users can also use EASE Focus software to aid in the design and implementation of a WideLine-10 array. 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. 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. BI AMP: The "full-range" LF input is applied to pins 1+ and 1- and the -6 dB per octave shading network is applied to one of the LF transducers using the mF (UNSHADED) SELECT switch. TRI AMP BI AMP MF (UNSHADED) SELECT Switch The WideLine-10 is a 3-way design (shaded, non-shaded and highfrequency) with shading provided by a passive network in BI AmP mode or upstream signal processing (DSP) in TRI AmP mode. 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 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 2 Component WL2102 WL2102-w PL-4. 0 WL SmALL GRID Weight 70 lb / 31. 8 kg 83 lb / 37. 7 kg 37 lb / 16. 8 kg 33 lb / 15. 0kg 4:1 design Factor 2300 lb / 1040 kg 2500 lb / 1130 kg ­ 1800 lb / 794 kg 5:1 design Factor 1800 lb / 836 kg 2000 lb / 909 kg ­ 1400 lb / 636 kg 7:1 design Factor 1300 lb / 597 kg 1400 lb / 649 kg 1423 lb / 646. 8 kg 1000 lb / 455 kg 10:1 design Factor 920 lb / 418 kg 1000 lb / 455 kg 996 lb / 452. 7 kg 700 lb / 318 kg 5 Rigging WideLine-10 enclosures use a three-point suspension system. The system consists of front, left/right, captive articulated joints and a single rear link bar. Articulation is in 2° increments using the first location on the link bar. Use the first pin location (closest to the end) on the link arm for setting in normalized 2° increments. The left-side example shows two enclosures linked for 8° of splay. The ball-lock pin is inserted into the 8° position in the rear block while passing through the "normal" pin hole in the link. When the "+3" location is used, an additional 3° are added to the "normalized" location. [. . . ] 19. 5" (696 mm) Bumpers Standard L-track 8 Stacking the WL SmALL Grid The WL SmALL GRID comes with two aluminum I-bars used for aligning and securing the frame to QSC's 215SB or 215PCm subwoofer. To use the I-bars, simply slide each one into the small frame's L-track and secure with a stud fitting. Then, turn the frame over (I-bars on the bottom) and slide the exposed I-bars into the subwoofer's L-track. Note that the stud fittings used are not required to be load rated as they only retain the I-bars from moving laterally. [. . . ]
