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
the KLA181 offers the same highly efficient power amp module
in a 1000 W configuration. This efficient design enables up to five
efficient 500 W x 500 W power amp module and
KLA models (any combination of KLA12 and KLA181) to be driven
off of a single
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
connectors, Attenuation Control and LED indicators for Signal and
Limit, as well as discrete LED indicators for Power/Standby status.

KLA Series System Configurations
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 housed on a multiple difraction aperture waveguide.
This waveguide design is based
upon similar principles found on
our patented WideLine™ Series
waveguides and the waveguides found
on our K Series products. Designed to
be used exclusively as a fixed arcuate
line array, each KLA12 is configured
for a 90˚ x 18˚ coverage angle,
allowing 90˚ vertical arrays to be
SOLO™ Rigging System
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.
KLA12’s Ar-Q™ (Arcuate Equalization) processing enables users to
quickly tune and configure the array, making appropriate frequency
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
configured using only five boxes (most
other solutions require six). KLA’s
resulting in an evenly balanced
and accurate tonal curve. QSC’s
proprietary Intrinsic Correction™
actively adjusts time, frequency
and amplitude response
to achieve a maximally flat
bandpass target.

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.

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
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.
KLA enclosures are engineered for a 10:1 design factor. Use a KLA
AF12 Array Frame or the M10 Integrated Suspension points to
suspend one KLA Array consisting of one of the following three array
configuration options. The maximum number of KLA12 Loudspeakers
