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 module and the KLA181 offers the same highly efficient power amp module in a 1,000 watt 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, 120 volt 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, Limit, Power and Standby status.

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. 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.

The KLA12 Ar-Q™ (Arcuate Equalization) processing enables users to quickly tune the array, making appropriate frequency compensation 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™, first introduced with the WideLine™ Series, actively adjusts time, frequency and amplitude response to achieve a maximally flat bandpass target.

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.
