Qsc K12 Benutzeranleitung

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
s
provides for matched LF and HF coverage 
across the entire listening area, eliminating 
unnatural ”dead” or ”hot” frequency zones.
s
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.
s
extended low-frequency response by actively 
managing low-frequency transients without 
degradation of the underlying signal or 
adjacent frequencies.
