The QSC K Series is quite simply The New Standard in lightweight powered
loudspeaker systems. Under the direction of Pat Quilter, QSC's team of
amplifier engineers have created a new standard in Class D power modules
unparalleled in the industry. Next, breaking from the traditional
loudspeaker paradigm, every model is fitted with the identical 1.75" HF
device (fullrange 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 (fullrange
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 (fullrange 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.
Fullrange 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 fullrange 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).
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.
