    The KLA Series brings the power and sophistication of a line array system into an easy-to-use product significantly redefining the line array product category. With its simple Lift, Click and Play approach, KLA can be deployed in a fraction of the time required by comparable line array products. This fixed arcuate, active line array system is ideal for a wide range of portable and permanently installed applications ranging from live entertainment to houses of worship or other venues where a line array system is desired.

    Housed in a rugged ABS enclosure that results in both light weight and long-term durability, the KLA12 features a 12-inch low-frequency transducer coupled with a 1.75-inch compression driver housed on a multiple difraction aperture waveguide. This waveguide design is based upon similar principles found on our patented WideLine Series waveguides and the waveguides found on our K Series products. Designed to be used exclusively as a fixed arcuate line array, each KLA12 is configured for a 90° x 18° coverage angle, allowing 90° vertical arrays to be configured using only five boxes (most other solutions require six). KLA's unique self-contained SOLO (Single-Operator Logistics) Rigging System enables users to quickly assemble (and disassemble) the line array in a fraction of the time without the need for special tools or external hardware.

    KLA12's Ar-Q (Arcuate Equalization) processing enables users to quickly tune and configure the array, making appropriate frequency adjustments based on the number of boxes. With the click of a dial, the user can select the total number of boxes deployed in the array resulting in an evenly balanced and accurate tonal curve. QSC's proprietary Intrinsic Correction actively adjusts time, frequency and amplitude response to achieve a maximally flat bandpass target.
