[. . . ] Damage to, or loss of any software or data residing on the product is not covered. When providing repair or replacement service, QSC will use reasonable efforts to reinstall the product's original software configuration and subsequent update releases, but will not provide any recovery or transfer of software or data contained on the serviced unit not originally included in the product. Customers may have additional rights, which vary from state to state or from country to country. In the event that a provision of this limited warranty is void, prohibited or superseded by local laws, the remaining provisions shall remain in effect. [. . . ] 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. 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. 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!

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. With the use of the second location, 1° degree increments can be obtained starting at 3°. The total available angular increments are: 0, 2, 3, 4, 5, 6, 7, 8, 9, and 10°. No ancillary items are needed to suspend the enclosures from the WideLine-10 array frame. All ball-lock pins are equipped with a lanyard to help prevent loss. 1 2 1. Front Articulated Joint--Slide the joint out of the receiver tube by sliding the retaining screw upward. Then lock in place using the ball-lock pin. Front Articulated Joint (Knuckle) Hardware Expose the end of the articulated joint by locating the joint's retaining screw protruding from the front of the receiver tube and sliding it upward. [. . . ] When stacking a WL SMALL GRID on top of QSC's 215SB or PCM cabinet, use the I-beam inserts (1 in each L-track) to assure proper alignment and to firmly secure the frame to the 215 cabinet. Secure using stud fittings. I-beam stacking bar: slide into L-track on WL SMALL GRID, then align and slide into L-track on subwoofer window. Do not stack more than four (4) enclosures on a WL SMALL GRID. Care We suggest wiping down all screws, pins, hardware, and frames with LPS® Dry Film Lube or Starrett m1® All Purpose Lube before and after outside gigs to help prevent oxidation. This will not only prevent the formation of rust and other oxides, but also provide lubrication, adding to the longevity and ease-of-use of the WideLine-10 product.
