K8.2 | K10.2 | K12.2

The QSC K.2 Series represents the best-in­class loudspeaker for today’s demanding
audio professionals. The perfect combination
of elegant design, superior audio
performance, high functionality, simple and
intuitive operation, and genuine QSC reliability,
K.2 delivers extraordinary results for users in
both portable and installed applications.

Advanced Power and DSP: The 2000 Watt
power module delivers ample burst and
continuous power for the loudspeaker’s
premium drivers. It has been designed with
very low-noise fan cooling, enabling the
enclosures to be used in settings where
background noise must be kept to a minimum.
Carefully tailored, subtle and sophisticated
dynamics processing is used to protect the
drivers from damage and the performance
from distortion.

Presets: The user may select from an
extensive list of factory preset EQ contours
including Live, Dance, Monitor, and many
more.

Scenes: Savable and recallable Scenes can
store information like user EQ, Delay, and input
configuration settings.

Inputs: A pair of balanced combo XLR/F plus
1/4" TRS connectors with independent gain
control are provided. The first is equipped with
selectable MIC/LINE (Microphone or Line)
level input while the second offers selectable
HI-Z/LINE (High Impedance or Line) level
input, specifically for musical instruments.
Both inputs are connected directly to a pair
of XLR/M throughput connectors so that the
signals may be “daisy-chained” to another
audio device. A 3.5 mm TRS input jack with
independent gain control is also provided for
connection of sources such as smart phones,
computers, and MP3 players.

Outputs: In addition to the two throughput
XLRs, a line-level output with the mixed
signal from all inputs is also provided.

(An optional security cover (K.2 LOC)
may be installed to prevent unauthorized
tampering of settings)

Coverage: DMT
Transition) design matches the coverage
angle of the woofer at the cross-over
frequency with the horn pattern to ensure
uniform response across the coverage
area. Intrinsic Correction™ techniques are
also employed ensuring smooth power
response from the loudspeaker. The result
is an extremely accurate loudspeaker that
behaves well in a wide range of acoustic
spaces with little or no equalization.

Flexible Design: Each model is housed in a
rugged ABS enclosure with a professional yet
unobtrusive appearance that is at home
in any application. Each model can be
utilized in either main PA or floor monitor
applications, while ergonomic handles
and a heavy-duty steel grille with fabric
lining further enhance overall appearance
and functionality. The dual pole cups allow
a zero or 7.5 degree downward tilt when
deployed on a pole. This allows for more
even coverage across the listening area and
less problems due to rear wall reflections.
For suspended applications, integrated M10
fittings with a single pullback are included
to accommodate M10 eyebolts. An optional
yoke mount accessory is also available for
permanent installation to walls and
ceilings or for temporary attachment to truss
(requires 3rd party hardware).

6-Year Warranty: Robust QSC reliability
backed by a global 6-Year Warranty*
