QSC K.2 Series: 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 & DSP: The 2000 Watt (Peak) 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.
Two-Way Driver Design: The QSC K.2 Series powered loudspeaker features
a two-way driver design with a 1.4" titanium diaphragm compression driver and a
10" cone woofer. The 1.4" high frequency driver receives 200 watts of Peak
power, while the 10" low frequency driver receives 1800 watts of Peak power. The
two-way powered loudspeaker delivers a frequency range of 56-20kHz (-6dB) with a
nominal coverage angle of 90 degrees.
DMT (Directivity Matched Transition: DMT (Directivity Matched
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
Inputs: The K.2 Series powered speaker has three separate inputs - two
combination XLR / 1/4" Phone Jack (Inputs A-B) and one 1/8" (3.5mm) TRS jack
- Balanced Combo XLR / 1/4" TRS Jacks (A-B): 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.
- 1/8" (3.5mm) TRS Input: A 3.5mm TRS input jack with independent
gain control is also provided for connection of sources such as smart
phones, computers, and MP3 players.
Outputs: Both balanced combo inputs are connected directly to a pair
of XLR/M throughput connectors so that the signals may be "daisy-chained" to
another audio device. In addition to the two throughput XLRs, a line-level
output with the mixed signal from all inputs is also provided.
Multi-Function Display: The K.2 Series powered loudspeaker provides a
multi-function digital display for control and selection of loudspeaker
functions including presets, scenes, crossover, EQ, delay, and frequency
- EQ Presets: You can 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.
Rugged Enclosure: The QSC K.2 Series speaker is housed in a rugged
impact resistant ABS enclosure for long life and lasting durability Ergonomic
handles and a heavy-duty, powder-coated steel grille with fabric lining further
enhance overall appearance and functionality. Its refined, professional
appearance looks great in practically any application.
Mounting Options: The K.2 Series loudspeaker has been designed to sit
on the floor, stage, a subwoofer enclosure, be suspended, or be pole mounted on
a 35mm diameter loudspeaker support pole.
- Pole Mount: The QSC K.2 Series speaker is equipped with two 35mm
pole sockets that allows use on a speaker stand or on a pole over a
subwoofer (the subwoofer must have a 35mm pole socket capable of supporting
the loudspeakers). One socket is for vertical mounting, the other for
tilting the enclosures down 7.5 degrees.
- Suspension Rig: In addition, the K.2 Series speaker has features
designed for various suspension methods. It features two M10 threaded
inserts for suspension with eyebolts and a built-in pull-back ring. There
are also yoke accessories (model numbers: K8.2 YOKE, K10.2 YOKE, K12.2 YOKE)
for each model that can mount either to the sides of the cabinet or to the
top and bottom. These yokes allow for rigid mounting to structures and
rotation of the speaker system.
Note: This is a powered loudspeaker containing an internal power
amplifier that produces heat. Allow a minimum of 6" clearance at the back of the
cabinet for convection cooling. Keep anything that might restrict airflow away
from the rear of the enclosure.
Applications: The K.2 Series has been primarily designed for portable
audio reinforcement. This includes a variety of uses in reinforcement for
entertainers and presenters. All are designed to perform well on their own in
full-range audio. They can be used singly, in stereo pairs, or in distributed or
delayed systems. They perform extraordinarily well as both main reinforcement
systems and as floor monitors.
V-Lock Power Cord: The V-LOCK power cord has a special
latching feature to prevent the power cord from being unintentionally removed.
The IEC plug and socket are both blue in color so the power cord can be
identified as a K.2 Series loudspeaker cord.
