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.
KLA Power Module
The KLA Series is comprised of two models: the KLA12 12-inch, 2-way loudspeaker and the KLA181 18-inch subwoofer. The KLA12 features a highly efficient 500 W x 500 W power amp module and the KLA181 offers the same highly efficient power amp module
in a 1000 W configuration. This efficient design enables up to five
KLA 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.
In an installed application, multiple KLA Series loudspeakers can be “daisy-chained” for total gain control from a single remote pot wired to the on-board Phoenix-style connector. Additional power module characteristics on KLA include a balanced, line-level XLR input in parallel with an XLR “Thru” connector, powerCON® In and Thru connectors, Attenuation Control and LED indicators for Signal and Limit, as well as discrete LED indicators for Power/Standby status.
KLA Series System Configurations
KLA12
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.
KLA181
In addition to DEEP™ DSP algorithm, GuardRail™, Auto Standby, balanced line-level XLR input with an XLR “Thru” connector, Attenuation Control and LED indicators, the KLA181 subwoofer also includes a polarity switch.
