Introduction

The WideLine loudspeaker system has been designed to pro- vide a compact system that has similar power handling, fre- quency response, and coverage of larger systems. Its primary uses include ballrooms, theatres, night clubs, houses of wor- ship, and small to medium size events for the corporate/indus- trial market.

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 pro- gram without subwoofers or bass modules. It has bass response to 52 Hertz (-3 dB) in a small format package. Its 3- way, biamp or triamp design keeps required amplification to a minimum.

WideLine’s exceptionally wide dispersion practically elimi- nates the need for “side” or “fill” hangs when used as the main array. Its wide dispersion also provides enhanced cover- age when used as a center cluster or as a downfill or under- hang enclosure when used with larger format line array systems.

Wide dispersion is accomplished with a 3” (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 line array performance.

Internal, mid-frequency shading can be switched to either 10” (254mm) transducer. Both transducers handle the low-frequen- cies, but only the non-shaded transducer handles the mids.

This provides smoother pattern control at the mid-high cross- over. With selectable shading, the enclosures can be used as house right or left by flipping the switch, not the enclosure.

The enclosure is constructed of lightweight cored-composite and weighs only 70lbs. (31.8kg), including the self-contained rigging hardware. The hardware allows for simple vertical splay angle adjustment of 0, 2, 3, 4, 5, 6, 7, 8, 9, and 10° between enclosures. Two array grids are available. The small array frame supports up to 8 enclosures flown or 4 enclosures stacked. The large array frame supports up to 24 enclosures flown or 12 enclosures stacked.

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 grid 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 sepa- rately; downloadable from the QSC website or contact QSC for more information.

Like all ISIS products, WideLine design focuses on accurate audio performance, rapid set-up, and reduced labor requir- ments. Ease of transportation, assembly, use, and self-con- tained rigging hardware make WideLine the clear choice.

Combined with the ISIS 82H, 102M, 102W, 122M, 152M, 215PCM, and 215SB, the WideLine array system provides the most comprehensive toolbox for any sound reinforcement pro- fessional.
