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.

WL 2102 specifications

The QSC Audio WL 2102 is an advanced, high-performance loudspeaker designed for professional audio applications. At the heart of its appeal is the integration of innovative technologies that deliver exceptional sound quality, reliability, and versatility. The WL 2102 is particularly well-suited for a variety of environments, including live performances, theaters, auditoriums, and corporate events.

One of the standout features of the WL 2102 is its dual 10-inch low-frequency drivers, which provide powerful bass response and clarity across a broad frequency range. The speaker is engineered to deliver a frequency response of 50 Hz to 20 kHz, ensuring that it can reproduce both low-end punch and high-frequency detail effectively. This wide frequency range makes it an ideal choice for applications where nuanced audio reproduction is critical.

The WL 2102 utilizes QSC's proprietary DMT (Directivity Matched Transition) technology. This ensures that the sound is evenly distributed across the coverage area, providing consistent sound quality and minimizing feedback issues. DMT helps to maintain clarity and intelligibility, whether the audience is seated at the front or the back of the venue.

Another important characteristic of the WL 2102 is its robust construction. Built with a durable enclosure that can withstand the rigors of touring and live events, the loudspeaker features a high-frequency horn coupled with advanced waveguide technology. This design enhances the speaker's projection and allows for greater control over dispersion, making it easier to tailor sound to specific environments.

In terms of connectivity, the WL 2102 is equipped with versatile input options, ensuring compatibility with various audio systems. It can be used in both passive and bi-amped configurations, giving audio engineers flexibility in setup and sound design. Additionally, the speaker's built-in rigging points make it straightforward to install and deploy in both fixed and portable setups.

The WL 2102 is also designed with thermal protection and built-in limiters, safeguarding the drivers during extended use and ensuring reliability in high-demand situations. This attention to safety and performance underlines QSC's commitment to quality, making the WL 2102 a trusted choice for audio professionals.

In conclusion, the QSC Audio WL 2102 represents a blend of advanced engineering, powerful sound capabilities, and durable construction. Its array of features and technologies allows it to excel in a wide range of applications, making it a versatile and dependable solution for any audio engineer or performer seeking exceptional sound reinforcement.
