WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation, placement or array. Any such condition severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term, unexpected overloading. [. . . ] The switch handle points to the side of the unshaded (full-range) low-frequency transducer. A B MF (UNSHADED) SELECT MF (UNSHADED) SELECT Switch: BI AMP Mode Pins 1+, 1-6dB per octave LF Transducer A LF Transducer B Pins 2+, 2- : not used Pins 3+, 3- : not used Pins 4+, 4- HF Transducer TRI AMP: The internal -6 dB per octave network is NOT applied to either LF transducer. Shading is accomplished with signal processing. The switch handle points to the side of the non-shaded (full-range) low-frequency transducer ONLY IF the full-range signal is applied to pins 1+ and 1- and the shaded signal to pins 2+ and 2-. Default position for TRI AmP mode is position A; if put in position B, connections to LF transducers A and B are interchanged. MF (UNSHADED) SELECT Switch: TRI AMP Mode Pins 1+, 1- LF Transducer A Pins 2+, 2LF Transducer B Pins 3+, 3- : not used Pins 4+, 4HF Transducer 3 Input Connections The input connectors are a pair of Neutrik NL8's wired in parallel. Connections for bi-amp and tri-amp vary (Table 1). The pin designations for the NL8FC cable connector is shown for reference, bottom right. In TRI AMP mode, the MF (UNSHADED) SELECT switch position determines the input connector wiring!Unexpected results may occur if switch positions and wiring are not strictly controlled. The WideLine-10 loudspeaker is not equipped with a crossover network. All signal processing must be done before connecting audio power to the loudspeaker. Do not connect full-range audio to the high-frequency transducer or damage may result!

Hidden structural members can have hidden structural weakness. · 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. [. . . ] Use this link for attaching the rear of the first enclosure. The frame allows for up or down angle options for use with either stacking or suspending. The 4° "normal" locations on the link system will yield a net 0° vertical inclination. Use 4° link location for 0° vertical inclination. WL SmALL Grid Do not stack more than four (4) enclosures on a WL SMALL GRID. 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. [. . . ]
