The QSC KLA12 is an active, fixed‑arcuate line array loudspeaker designed for fast deployment and consistent coverage in live sound, corporate events, houses of worship, and installed applications. It uses a 12‑inch LF driver and 1.75‑inch compression driver powered by a 500‑watt + 500‑watt Class‑D amplifier module, delivering strong output with a frequency range extending down to 44 Hz and a peak SPL of 131 dB. The cabinet provides a 90° horizontal by 18° vertical coverage pattern, and QSC’s SOLO rigging system allows tool‑free arraying, supporting up to five KLA12 modules in a flown configuration. Additional features include Ar‑Q array equalization for quick tuning based on the number of boxes, DEEP DSP for extended low‑frequency performance, and powerCON input/thru connectivity for simplified power linking.
