The QSC WideLine is a full range line array loudspeaker system designed for use in a wide range of venues. The WideLine reportedly features an open, natural sound quality and wide 140° horizontal coverage pattern.
WideLine is a three-transducer system and can be operated in either biamplified or triamplified modes. Both 10" diameter low-frequency transducers are used to cover the lowest frequency range. One driver covers only low frequencies while the range of the other extends through the mid frequencies to the mid/high crossover point.
The use of a single midrange transducer allows the horizontal coverage pattern to remain as wide as possible and assures smooth response both on and off axis at the transition to the diffraction slot loaded high frequency section. Biamplification uses passive elements to affect the required frequency response shading of the low-frequency drivers and offers reduced amplifier channel counts and simplified wiring. Triamplification allows the required low-frequency shading to be controlled with greater precision via active electronics and is recommended where maximum output and highest sound quality are required.
The WideLine's 16 ohm per transducer low frequency impedance is designed to optimizes allocation of amplifier channels. In biamp mode the LF/MF sections of up to four enclosures can be powered by one amplifier channel operating into a two ohm load. In triamp mode the LF and MF sections of up to eight enclosures can be powered by a single two channel amplifier.
The high-frequency section consists of a 1.4" exit, 3" 16 ohm, neodymium compression driver, mounted on a proprietary multiple aperture diffraction slot waveguide. This patented device produces the ideal linear source needed for good line array performance, and facilitates the enclosure’s exceptionally wide horizontal coverage.
The WL2102 features lightweight, highly weather resistant cored composite construction resulting in a net weight of just 70 lbs per enclosure; less than half the weight of some conventional designs.
The enclosure of the WL2102-w is constructed of industry standard birch plywood resulting in a slight increase in weight; 83 lbs/37.7 kg vs. 70 lbs/31.8 kg for the WL2102, at a cost savings for more price sensitive applications where the light weight and weather resistance of the cored composite enclosure are not required. The mechanical design is designed to allow composite and plywood enclosures to be arrayed together.
Wideline features a unique 3-point suspension system allowing construction of arrays of up to 24 enclosures (5:1 design factor). A 12-enclosure hang will maintain a 10:1 design factor which may be dictated by local regulations and practices. Vertical splay angles between adjacent enclosures are adjustable in one-degree increments from zero to ten degrees. All hardware required to construct an array is permanently attached to the enclosure; there are no loose parts to misplace.
