The QSC K Series is quite simply The New
Standard in lightweight powered loudspeaker
systems. For starters, each of the four models
features an all new, Pat Quilter designed
1000 watt continuous QSC Class D power
module. Next, breaking from the traditional
loudspeaker paradigm, every model is fitted
with the identical 1.75" HF device (full-range
models) and woofers of the same high quality
for unparalleled performance, regardless of
speaker size.
Extensive DSP processing is employed
throughout, providing levels of sonic clarity
and total output that defy the system’s size
and weight.
Premium-grade materials, advanced construction
processes and multiple mounting and
suspension options allow for a wide range of
live and installed applications.
Combo XLR and 1/4" TRS inputs accept both
Mic and Line Level input while a set of RCA
phono inputs (except 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
outputs are also provided on each channel for
additional output flexibility.
On-board switches provide preset EQ settings.
The HF setting (full-range models) can be
set to VOCAL BOOST for additional presence
in the critical mid-frequency area or FLAT for
accurate reproduction of the incoming signal.
The LF switch can be set to NORM, DEEP™ for
additional bass extension, or EXT SUB (full-range
models) for use with an external subwoofer. The
rear panel LED switch can be set to POWER,
illuminating the front-mounted LED when the
unit is powered on, OFF for applications where
it is not desirable to illuminate the front LED, or
LIMIT which indicates to the system operator
that the clip limiter circuit has been engaged
during operation.
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 an additional measure
of sonic clarity 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 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, low-noise 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 a
potentiometer (not included) connected 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.
Extensive DSP
• DMT™ (Directivity Matched Transition)
provides for matched LF and HF coverage
across the entire listening area, eliminating
unnatural ”dead” or ”hot” frequency zones.
• Intrinsic Correction™, first featured in our
high-end line-array products maps 65-75
spacially-averaged measurements to IIR and
FIR filters that actively adjust time, frequency
and amplitude response to a maximally
flat bandpass target. The result is a speaker
that behaves equally well across the entire
sound field.
• DEEP™ and excursion limiting allow for
extended low-frequency response by actively
managing low-frequency transients without
degradation of the underlying signal or
adjacent frequencies.
• GuardRail™ protection, first introduced on
our GX Series amplifiers protects both the
amplifier module and your performance from
unnatural and destructive clipping.
