XENYX QX1202USB/QX1002USB User Manual
1. Introduction
The XENYX Series represents a milestone in the development of mixing console
technology. With the new XENYX microphone preamps including phantom power
as an option, balanced line inputs and a powerful effects section, the mixing
consoles in the XENYX Series are optimally equipped for live and studio
applications. Owing to state-of-the-art circuitry your XENYX console produces
a warm analog sound that is unrivalled. With the addition of the latest digital
technology these best-in-class consoles combine the advantages of both analog
and digital technology.
The microphone channels feature high-end XENYX Mic Preamps that compare
well with costly outboard preamps in terms of sound quality and dynamics and
boast the following features:
•
130 dB dynamic range for an incredible amount of headroom
•
A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear
reproduction of even the finest nuances
•
The extremely low-noise and distortion-free circuitry guarantees absolutely
natural and transparent signal reproduction
•
They are perfectly matched to every conceivable microphone with up to
60 dB gain and +48 volt phantom power supply
•
They enable you to use the greatly extended dynamic range of your
24-bit/192-kHz HD recorder to the fullest, thereby maintaining optimal
audio quality
“British EQ”
The equalizers used for the XENYX Series are based on the legendary circuitry of
top-notch consoles made in Britain, which are renowned throughout the world
for their incredibly warm and musical sound character. Even with extreme gain
settings these equalizers ensure outstanding audio properties.
KLARK TEKNIK FX Processor
Additionally, your XENYX mixing console has a KLARK TEKNIK effects processor
with 24-bit A/D and D/A converters included, which gives you 100 presets
producing first-class reverb, delay and modulation effects plus numerous
multi-effects in excellent audio quality.

Caution!
◊
We should like to draw your attention to the fact that extreme volumes
may damage your hearing and/or your headphones or loudspeakers.
Turn the MAIN MIX control and PHONES control in the main section fully
counterclockwise before you switch on the unit. Always be careful to
set appropriate volume levels.
1.1 General mixing console functions
A mixing console fulfils three main functions:
•
Signal processing:
Preamplification
Microphones convert sound waves into voltage that has to be amplified
several-fold; then, this voltage is turned into sound that is reproduced
in a loudspeaker. Because micro phone capsules are very delicate in their
construction, output voltage is very low and therefore susceptible to
interference. Therefore, mic signal voltage is amplified directly at the mixer
input to a higher signal level that is less prone to interference. This higher,
interference-safe signal level has to be achieved through amplification using
an amplifier of the highest quality in order to amplify the signal and add
as little noise to it as possible. The XENYX Mic Preamp performs this role
beautifully, leaving no traces of noise or sound coloration. Interference that
could take place at the preamplification level could affect signal quality
and purity, and would then be passed on to all other devices, resulting in
inaccurate sounding program during recording or playback.
Level-setting
Signals fed into the mixer using a DI-box (Direct Injection) or the output of a
sound card or a keyboard, often have to be adjusted to the operating level of
your mixing console.
Frequency response correction
Using the equalizers found in each channel strip, you can simply, quickly and
effectively adjust the way a signal sounds.
•
Signal distribution:
Individual, processed signals from the channel strips are compiled on
busses and are fed into the main section for further processing. Connections
for recording equipment, power amplifiers, headphones as well as RCA
connectors are available here. The mix is sent to the internal FX processors or
external effects processors via aux sends and returns. Similarly, a mix can be
created for the musicians on the stage (monitor mix).
•
Mix:
All other mixing console functions fall under this vital category. Creating a
mix means primarily adjusting the volume levels of individual instruments
and voices to one another as well as giving them the appropriate weight
within the overall frequency spectrum. Likewise, you’ll have to sensibly
spread individual voices across the stereo image of a signal. At the end of
this process, adjusting the level of the entire mix to other equipment in the
signal path is required (e. g. recorder/crossover/amplifier).
The interface of BEHRINGER mixing consoles is optimized for these tasks,
enabling you to easily keep track of the signal path.
