The QSC K.2 Series™ represents the best-in-class
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: Directivity Matched Transition™
(DMT) 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).
Robust QSC quality and reliability backed
by a global 6-Year Warranty with product
registration.
