High Quality Construction
The QSC K12 offers unparalleled performance with its 1.75" HF
driver, breaking from the traditional loudspeaker paradigm.
Premium-grade materials and advanced construction processes have
been used, as well as extensive DSP processing is employed
throughout, providing levels of sonic clarity and total output that
defy the system's size and weight.
Flexible Connectivity
Combo XLR and 1/4" TRS inputs accept both Mic and Line Level
input while a set of RCA phono inputs 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.
Rugged Housing
The K12 features a rugged ABS enclosure with a professional
appearance that is at home in any application. The internal
rigidity offers an additional measure of sonic clarity, making ABS
a far more robust material than conventional speaker plastics with
fantastic sound quality. Ease of transport and long term durability
is ensured with the K12's ergonomic aluminium handles and a highly
protective steel grille.
Tilt-Direct Mounting System
The unique Tilt-Direct pole cup mounting system allows acoustic
energy to be kept on the audience and off reflective surfaces with
the simple turn of the dial, engaging a 7.5 degree downward tilt of
the speaker. This is ideal for applications where maximum coverage
from a high-positioned speaker is desired.
Mixing and EQ
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.

Extensive DSP enhances system performance
- 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 spatially-averaged measurements to
IIR and FIR filters that actively adjust time, frequency and
amplitude response to a maximally flat band pass 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 protects both the amplifier module
and your performance from unnatural and destructive clipping.
