ISIS WideLine Loudspeaker User Manual Model WL 2102 *TD-000188-00* TD-000188-00 rev.
IMPORTANT SAFETY PRECAUTIONS Install in accordance with QSC Audio Product's instructions and under the supervision of a licensed Professional Engineer. 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.
Introduction The WideLine loudspeaker system has been designed to provide a compact system that has similar power handling, frequency response, and coverage of larger systems. Its primary uses include ballrooms, theatres, night clubs, houses of worship, and small to medium size events for the corporate/industrial market.
Three way Active/Two way Active Switch Two way active: The “full range” LF input is applied to pins 1+ and 1- and the -6dB per octave shading network is applied to one of the LF transducers using the Low Frequency Select switch (above). Three way active: Shading network is NOT applied (shading must be provided by upstream signal processing). Connect the full-range input signal to pins 1+ and 1-, connect the shaded (processed) signal to pins 2+ and 2-.
Input Connections The input connectors are a pair of Neutrik NL8's wired in parallel. Connections for biamp and triamp vary, see Table 1. The pin designations for the NL8FC cable connector is shown for reference, bottom right. Note! In three way mode, the Low Frequency Select switch position determines the input connector wiring! Unexpected results may occur if switch positions and wiring are not strictly controlled. The WideLine loudspeaker is not equipped with a crossover network.
Rigging CAUTION: SUSPENDING SPEAKERS PRESENTS A RISK OF SERIOUS INJURY OR DEATH. PLEASE USE CAUTION TO ASSURE THAT MOUNTING SURFACES ARE CAPABLE OF SUPPORTING AT LEAST FIVE TIMES THE WEIGHT OF THE SPEAKER AND MOUNTING APPARATUS. USE ONLY LOAD RATED HARDWARE. ALWAYS CONSULT WITH A CERTIFIED PROFESSIONAL WHEN IMPLEMENTING OVERHEAD SUSPENSION. The large array frame’s maximum array is twenty-four (24) enclosures. Weight of a twenty-four box system is only 1680lbs and the large array frame weighs 83lbs.
Adjusting the Angle Between Enclosures (Splay) The illustration shows the rear pin block of two enclosures joined by the upper enclosure’s rear link arm. Use the first pin location (closest to the end) on the link arm for setting in normalized 2° increments. The leftside 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.
Large Array Frame (continued) The mounting plate and link on are located on the bottom side of the frame assembly. Use this link for attaching the rear of the first enclosure. The grid allows for up or down angle options for use with either stacking or flying. The 4° “normal” locations on the link system will yield a net 0° vertical inclination. Use 4° link location for 0° vertical inclination Small Array Frame (Stacking Grid) Do not fly (suspend) more than eight (8) enclosures form the small array frame.
Stacking the Small Array Frame The small array frame comes with two aluminum I-bars used for aligning and securing the frame to QSC’s “215” 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. Secure the I-bar with a stud fitting.
Preliminary System Specifications (subject to change without notice) Configuration: Three way, biamp (active two way) or triamp (full three way active) Frequency Response: 52Hz - 18KHz (+/- 3dB) Sensitivity: biamp: 97dB (2.83v @ 1m) triamp: 99dB (2.83v @ 1m) Nominal coverage: Horizontal:140deg.
