K.2 Series Powered Loudspeakers
FAQ
Q. What does K.2 stand for?
A. The .2 indicates that this is the new, 2nd generation K Series.
Q. What is the main difference between legacy K and
K.2 Series?
A. There are many differences:
* K.2 amp has over twice the Peak power of legacy K with
more efficient distribution of power (1800 W for the LF +
225W for the HF).
* K.2 has more powerful DSP, and now includes user-
adjustable crossover, delay & EQ
* K.2 has an LCD display with advanced functionality
and control
* K.2 has HI-Z (high impedance) inputs for passive instruments
* K.2 has a dual pole-cup for improved Center-of-Gravity
* K.2 8-inch model (K8.2) can be used as a floor monitor
* K.2 has a cloth-lined grill for a more elegant look
* K.2 has a 3.5mm (1/8”) mini-jack input
* K.2 has independent gain controls for each of the
three (3) inputs
* K.2 has a shallower monitor angle (55 degrees) on all
models.
Q. What is the difference between a Preset and a
Scene?
A. A Preset is a factory “voice” developed for specific applications
(for example, floor monitor, headset microphone or bass guitar).
A Scene is a total snapshot of all changes you have made,
and includes input type selected, preset selected, crossover
selected, plus any edits to delay or equalization.
Q. How many Presets are there?
A. There are eleven (11) Factory Presets including the Default
voicing.
Q. How many Scenes can I store?
A. You can store five (5) User Scenes.
Q. Can I name my Scenes?
A. No. The Scenes are simply numbered User 1-5.
Q. Why did you replace the single rotating Tilt-Direct
pole-cup with a dual pole-cup?
A. While the rotating Tilt-Direct™ pole-cup was certainly innovative
at the time, it did have one minor flaw: using the -7.5 degree
down angle actually shifted the weight of the loudspeaker
away from the C/G (Center-of-Gravity). The new dual pole-cup
ensures that the K.2 loudspeaker always rests on the C/G
.
Q. Why did you replace the Phono RCA with a 3.5mm
(1/8”) TRS mini-jack input?
A. Believe it or not, when QSC began developing the original K
series in 2006, there was no such thing as an iPhone. The
original phono RCA inputs were actually intended for common
DJ Mixers and CD Players at that time. Since the introduction
of the iPhone in 2007 there has been a rapid stream of smart
devices that have completely changed the way music is played.
As such, the Stereo 3.5mm (1/8”) TRS mini-jack has now
become the most ubiquitous connector type.
Q. Is the 3.5mm TRS mini-jack input actually Stereo?
A. It will accept a stereo source, but will always sum this down
to Mono.
Q. Does the K.2 have Bluetooth audio streaming?
A. No.
Q. Why did you remove the Remote Volume control?
A. The rear panel of the K.2 is considerably more compact than its
predecessor yet offers far greater functionality. Only a handful
of legacy K Series users ever took advantage of the Remote
Volume feature, therefore a decision was made to trade its
valuable real estate for some more widely-utilized functionality
on the K.2.
Q. Why does the rear LCD display dim?
A. The rear LCD display will dim after 30 seconds of inactivity.
This is to reduce ambient light glowing from the rear of the K.2
speaker on dark stages. This is especially valuable when used
as a stage monitor.
Q. Can I adjust the contrast on the rear LCD display in
different light settings (ie indoors vs outdoors)?
A. Yes. The contrast can be adjusted from the Utility
Settings Menu.
Q. Why does the K.2 take a few seconds longer to
power-up compared to the legacy K Series?
A. Unlike the legacy K models, the new K.2 features a
menu-driven LCD display which requires the addition of a
microprocessor. As would be expected, this microprocessor
has a small boot-time
.
Q. Why is there no boost on the 4-band user EQ?
A. It is a best practice among sound professionals to handle
loudspeaker equalization by cutting frequencies that are
excessive rather than by boosting frequencies that are
considered as lacking. Offering cut-only equalization has the
added benefit of minimizing the risk of feedback.
