QSC K12
QSC's K12 is a lightweight powered loudspeaker that features a 1000 Class D power
module and is fitted with an identical woofer and a 1.75" HF transducer. The K12
also features auto-standby mode, XLR & 1/4" TRS mic/line level ins, RCA phono ins,
direct outs on each channel, a balanced out for daisy-chaining up to three sources
and extensive DSP processing. EQ settings for both the high-freq. and low-freq. transducers
are adjustable on each unit. LEDs can be set to show when the unit is on or when
its clip limiter has been engaged. The extended bass LF setting allows for integration
of an external subwoofer into the sound system.
Features fly-mount options as well as the Tilt-Direct™ pole cup mounting system for
a 7.5° downward tilt for better sound coverage. Multiple units can be daisy-chained
for total gain control from a single remote pot. Also features a steel grille and
is housed in an ABS enclosure.

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.
