What's New - QSC K8.2 Application Manual

WHAT'S NEW

Let's look at the inputs on the K.2 loudspeakers. They're still somewhat familiar to the K user, but updated a bit. As with the
original K series, Input A again can be mic or line level, but Input B now can be either a line level input or a high-Z one suitable
for musical instruments that have passive magnetic or piezo pickups. That's right—the K.2 Series loudspeakers can be used as
guitar or bass combo amp, and they won't load down the instrument like a regular mic or line input would. Input C is a stereo-
summed-to mono channel with a 3.5 mm stereo jack, suitable for playback from portable digital audio devices such as phones,
MP3 players, etc.
The three inputs each have their own gain knob and get mixed down to provide signal for the digital signal processing (DSP) and
class D amplification stages. A line-level summed output provides a means to send the mixed signal on to other loudspeakers or
other devices.
The biggest advance is in the DSP capabilities of the K.2 loudspeakers. In addition to voicing and protection duties, the K.2
Series DSP offers an array of user-configurable parameters that include EQ, delay, and presets. Yes, presets.
K.2 loudspeakers have 11 presets so you can
quickly dial in a collection of settings tailored
to a certain application.

The standard voicing of the K.2 speaker
A voicing for live music reinforcement that lowers and balances frequencies that can be prone
to feedback in a live mix.
A voicing for live music reinforcement that offers slightly more high end than the "Live" voicing.
A voicing that focuses on high-end clarity and low end extension, primarily for Dance/Pop/Hip
Hop/etc music.
A voicing for using a stage monitor with a microphone that lowers and balances frequencies
that can be prone to feedback in a monitor mix.
A voicing for using a stage monitor without a microphone (such as a drum or keyboard monitor)
that offers more low frequency extension than Stage Monitor 1.
A voicing for a vocal mic plugged into input A, and an acoustic guitar plugged into channel B
that lowers and balances frequencies prone to feedback between those two input sources.
A voicing optimized to provide performance similar to that of a combo bass amplifier.
A voicing that lowers and balances frequencies that can be prone to feedback with common
handheld dynamic microphones when used without a mixer.
A voicing that lowers and balances frequencies that can be prone to feedback with common
headset microphones when used without a mixer.
A voicing that provides a more balanced overall speaker response with deeper extension to be
used as a nearfield or studio monitor for mixing.
