QSC KLA12-BK
12" 2-Way Active Line-Array Speaker, Black

OUR PART #  KLA12-BK


The QSC KLA12 line array loudspeaker can be deployed in a fraction of the time required by comparable line array products with its simple "Lift, Click and Play" approach. This fixed Arcuate (see details below), active line array speaker is ideal for a wide range of portable and permanently installed applications ranging from live entertainment, houses of worship or other venues where a line array system is desired.

The KLA12 features a highly efficient 500 watt by 500 watt power amp module. This efficient design enables up to 5 KLA models (any combination of KLA12 and KLA181 - additional units sold separately) 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.

Housed in a rugged ABS enclosure that results in both light weight and long-term durability, the KLA12 features a 12" low frequency transducer coupled with a 1.75" 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 5 boxes (most other solutions require 6).

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's 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.

For maximum deployment flexibility, KLA loudspeakers can be either ground deployed or flown.  As a ground stack, up to 2 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.

Arrays of up to 480 lbs. (218 kg) (with a maximum 5 KLA12 and 2 KLA181 enclosures - these additional units are sold separately) can be flown via the included M10 fittings or the optional KLA AF12 array frame.
