The WL2102 WideLine-10 Line Array Speaker from QSC is a full range line array loudspeaker designed for use in a wide variety of venues. The WideLine-10 features a wide 140° horizontal coverage pattern. It is a three transducer system and can be operated in either bi-amplified or tri-amplified modes. Both 10" 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 high-frequency transducer allows the horizontal coverage pattern to remain wide and to assure smooth response both on and off axis at the transition to the diffraction slot loaded high frequency section. Bi-amplification uses passive elements to affect the required frequency response shading of the low-frequency drivers and offers reduced amplifier channel counts and simplified wiring. Tri-amplification allows the required low-frequency shading to be controlled with greater precision via active electronics and is recommended where maximum output and high sound quality are required. The WideLine-10's 16 ohms per transducer low-frequency impedance optimizes allocation of amplifier channels. In bi-amp mode the LF/ MF sections of up to four enclosures can be powered by one amplifier channel operating into a 2-ohms load. In tri-amp 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 ohms, neodymium compression driver, mounted on a proprietary multiple aperture diffraction slot waveguide. The mechanical design allows composite and plywood enclosures to be arrayed together. WideLine-10 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. Vertical splay angles between adjacent enclosures are adjustable in 1° increments from 0 to 10°. All hardware required to construct an array is permanently attached to the enclosure. Two array frame models (sold separately) offer the user the flexibility to choose the right tool for the job. The AF2102, the larger of the two, can accommodate array sizes up 12 enclosures while maintaining a design factor of 10:1. The smaller AF2102-s does triple-duty; accommodating suspended arrays of up to six enclosures with a 10:1 design factor, acting as a base for ground-stacked arrays of up to six enclosures and as an attachment allowing WideLine-10s to be stacked atop QSC 215PCM and 215SB subwoofers.
