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. 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. 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.

Introduction

The WideLine loudspeaker system has been designed to provide a compact system that has unique power handling, frequency response. Its primary uses include ballrooms, theatres, night clubs, houses of worship, and small to medium size events for the corporate and industrial markets.

WL2102 enclosures are constructed of lightweight cored-composite and weigh 70 lb (31.8 kg). WL2102-w enclosures are constructed of birch plywood and weigh 83 lb (37.7 kg). The hardware allows for simple vertical splay angle adjustment of 0, 2, 3, 4, 5, 6, 7, 8, 9, and 10° between enclosures.

Wide dispersion is accomplished with a 3 inch (76mm) diaphragm, 1.4” (36mm) exit neodymium high-frequency driver mounted on a proprietary, patent-pending multiple aperture diffraction-slot waveguide. This device is the ideal linear source needed for wide angle line array performance.

Internal, mid-frequency shading can be switched to either 10” (254mm) transducer. Both transducers handle the low-frequencies, but only the non-shaded transducer handles the mids. This provides smoother pattern control at the mid-high crossover. With selectable shading, the enclosures can be used as house right or left by flipping the switch, not the enclosure.

Two array frames are available. The Stacking Frame is for suspended applications or stacking on top of QSC’s 215SB or 215PCM subwoofers. The large array frame is for suspended or ground stack applications.

The WideLine system is suitable for stand alone applications as a full range, articulate, high fidelity, sound reinforcement product with the ability to reproduce almost any musical program without subwoofers or bass modules. It has bass response to 55 Hz (-3 dB) in a small format package. Its 3-way, bi amp or tri amp design keeps required amplification to a minimum.

WideLine’s exceptionally wide dispersion practically eliminates the need for “side” or “fill” hangs when used as the main array. Its wide dispersion also provides enhanced coverage when used as a center cluster or as a downfill or underhang enclosure when used with larger format line array systems.

WideLine users can also use a software tool called EASE Focus to aid in the design and implementation of a WideLine 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. The software is available separately; downloadable from the QSC website or contact QSC for more information.

Like all QSC Audio products, WideLine design focuses on accurate audio performance, rapid set-up, and reduced labor requirements. Ease of transportation, assembly, use, and selfcontained rigging hardware make WideLine the clear choice.

TRI AMP/BI AMP Switch

TRI AMP: Shading network is NOT applied (shading must be

provided by upstream signal processing). Connect the fullrange 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 (per Table 1) to LF transducers A and B are interchanged.

BI AMP: The “full range” LF input is applied to pins 1+ and 1and the -6dB per octave shading network is applied to one of the LF transducers using the MF (UNSHADED) SELECT switch.

MF (UNSHADED) SELECT Switch

The WideLine is a three way design (shaded, non-shaded and high frequency) with shading provided by a passive network in BI AMP mode or upstream signal processing (DSP) in TRI AMP mode. This allows switch position selection for use as either “house left” or “house right”, without the need to invert boxes.

BI AMP: The shading switch allows either low frequency transducer to be selected as the shaded unit (bass only) by inserting a -6dB per octave network. The switch handle points to the side of the unshaded (full range) low-frequency transducer.

TRI AMP: The internal -6dB per octave network in 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.

Input Connections

The input connectors are a pair of Neutrik NL8's wired in parallel. Connections for bi amp and tri amp vary, see Table 1. The pin designations for the NL8FC cable connector is shown for reference, bottom right.

Note! 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 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!
