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 fraction of the time required by comparable line array products. Fixed arcuate, active line array system is ideal for 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 series is comprised of two models, KLA12 12-inch, 2-way loudspeaker and KLA181 18-inch subwoofer. The KLA12 features highly efficient 500W by 500W power amp module and the KLA181 offers the same highly efficient power amp module in a 1000W configuration. This efficient design enables up to five KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15A, 120V 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, 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, limit, power and standby status. Housed in rugged ABS enclosure that results in both light weight and long-term durability, KLA12 features a 12-inch low frequency transducer coupled with a 1.75-inch compression driver. Designed to be used exclusively as a fixed arcuate line array, each KLA12 is set at a 90° horizontal by 18° vertical splay angle, allowing 90° vertical coverage 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.
