The QSC K Series is quite simply The New Standard
in lightweight powered loudspeaker systems and will
satisfy the needs of the most demanding entertainers,
installers and A/V users. QSC’s team of amplifier
engineers has created a Class D power module
unparalleled in the industry. The series consists of
three, bi-amplified 2-way models ranging in woofer
size from 8" to 12" plus a dual 12" subwoofer.
The selection of woofer diameter and coverage for the
various K Series models is not arbitrary but is based
on acoustical science. K Series is designed using a
concept called Directivity Matched Transition™ (DMT™).
DMT matches the high-frequency coverage angle to
the natural coverage of the woofer at crossover
frequency. As a result, frequency response remains far
more uniform across the entire audience area. The K8
delivers wide 105° coverage making it a great choice
for performers who work in more intimate venues
where the audience is closer to the stage and spread
more widely. The more directional K12 with its 75°
coverage is a better choice when more “throw”
is needed. The K10, of course strikes a balance
between both width and throw. All models boast
the same 1000 watt power module and the
same high-quality, neodymium HF driver.
Extensive DSP processing is employed throughout,
providing levels of sonic clarity and total output that
exceed expectations for systems of this size and weight.
On-board switches select preset EQ contours. Combo
XLR and 1/4" TRS inputs accept either Microphone or
Line Level input while a set of RCA phono inputs (not
available on KSub) allow additional connectivity to
portable MP3 players, CD players and line-level mixers.
Up to three audio sources can be mixed internally and
summed to a balanced output for ”daisy-chaining”
of multiple units. Separate direct through-puts are also
provided on each channel for additional flexibility.
Full-range models are housed in rugged ABS enclosures
with a professional appearance that is at home in any
application. ABS is a far more robust material than
conventional speaker plastics and offers sonic
benefits due to its internal rigidity. Ergonomic aluminum
handles and a highly protective steel grille complete
the package for ease of transport and long term
durability. The K12 and K10 enclosures are also
designed for floor monitor use.
The K Series full-range models feature a unique
Tilt-Direct™ pole cup mounting system. A simple turn
of the dial engages a 7.5 degree downward tilt of the
speaker allowing acoustic energy to be kept on the
audience and off reflective surfaces for applications
where maximum coverage from a high-positioned
speaker is desired. Integrated M10 suspension
points allow for suspended applications with a
K Series M10 Kit (sold separately) or Yoke bracket
(sold separately).
The KSub is a dual-12" bandpass design, constructed
of premium birch and includes high-quality, anti-rattle
casters. The subwoofer features a threaded pole
receptacle for a positive, wobble-free connection to
a threaded speaker pole (included).
Remote gain control capability is offered via an
external potentiometer (not included) that may be
wired to the on-board Euroblock connector. In an
installed application, multiple K Series speakers can
be ”daisy-chained” for total gain control from a single
remote pot. Auto-standby mode is engaged after 5
minutes of inactivity and disengages instantly when
an audio signal is present.
