QSC WL2102 WideLine-10 Line

QSC WL2102 WideLine-10 Line

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.
