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 outputIn 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.
