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 watt by 500 watt power amp

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 Limit Power and Standby status.

KLA181 Subwoofer 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 for low frequency directivity control.

Rigging & Deployment
For maximum deployment flexibility KLA loudspeakers can be either ground deployed or flown. As a ground stack up to two KLA12 enclosures can be mounted over the KLA181 or the KW181 subwoofer via a threaded pole socket or without a sub using an appropriately rated loudspeaker stand.

KLA12 enclosures also feature the Tilt-Direct™ 35mm pole socket allowing the loudspeaker to be aimed downward 9° for the best audience coverage. Up to five KLA enclosures (any combination of KLA12 and KLA181) can be flown via M10 fittings on the top of each enclosure. An optional KLA AF12 array frame is also available.
