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 (K8, K10 and K12) 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.
