QSCQSC- WL2102-W-WHAudioWL2102-W-WHFeatures4731
• Multiple aperture diffraction slot waveguide provides exceptionally wide horizontal coverage (140°) and a near ideal vertical line source
• Exceptionally high output capability in a very compact form factor
• Bi-amp or tri-amp design
• Dual 10" long excursion, high power, low-frequency transducers
• Single 3" diaphragm neodymium compression driver
• WL2102 − Cored composite construction results in lighter weight
(70 lb, 31.8 kg) and greater weather resistance
• WL2102-w − Birch ply construction offers reasonable weight
(83 lb, 37.7 kg) at a lower cost
• Fully captive hardware design incorporates all components necessary for box to box rigging
QSCQSC- KLA12-BKAudio684284058041KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15 amp/120V (8A / 230V) electrical circuit. KLA loudspeakers incorporate QSC's DEEP™ DSP algorithm, providing extended bass response by actively managing potentially damaging low-frequency transients, and GuardRail™ circuitry protection which prevents the amplifier module from unnatural and destructive clipping. As an energy saving feature, the Auto Standby mode automatically engages after five minutes of inactivity but upon resumption of audio signal, the power module on the KLA will awaken instantly for immediate output.2999
