The KLA12 is part of the QSC KLA Line Array series. These arcuate, powered loudspeakers are known for generating sophisticated sound with relentless power in a user friendly line array system. Load in and be ready for sound check in no time with the unique Lift, Click, and Play design—the KLA12 may be either ground stacked or flown. This fixed system can be deployed as part of a portable touring sound system, or installed permanently in arenas, theaters, or places of worship and congregation. Pair the KLA12 and KLA181 in any combination of 5 with a daisy-chain XLR configuration for complete gain control from one remote pot.

Sound engineers will enjoy premium power efficiency and can run any combination of 5 KLA models on one 15 amp/120V electrical circuit. QSC has integrated an Auto Standby feature to put the speakers in standby mode after five minutes of output inactivity. When signal returns, the 500 x 500 Watt power amp module will re-engage and is capable of instant output. Power is delivered by powerCON in/thru connectors and the loudspeakers are housed in a durable ABS box that’s both rugged and light weight, resulting in hassle free operation and minimal maintenance.

The speaker is expressly designed for use in fixed arcuate line arrays, and has a 12:1 design factor with a 90 x 18° coverage pattern, allowing up to 5 units to be configured for 90 x 90° coverage. Most other systems require 6 units for the same coverage pattern. The KLA12’s SOLO (Single-Operator Logistics) Rigging System allows you to easily assemble and disassemble the line array in a short amount of time without special tools or external hardware.

Ar-Q (Arcuate Equalization) processing enables you to quickly tune the array, making appropriate adjustments based on the number of boxes in your array. By simply using a dial, you can choose the total number of boxes for a balanced and accurate tonal curve. Proprietary Intrinsic Correction technology adjusts the time, frequency, and amplitude response for a flat bandpass target.

Up to 2 loudspeakers can be mounted on a stand or over a sub for a ground stack, thanks to a threaded Tilt-Direct 35mm pole socket. The socket also allows you to aim the speaker 9° downward for the best audience coverage. M10 fittings in the top of the enclosure allow up to 5 units to be flown in a suspended rig. An optional array frame is also available separately for additional mounting options.
