1. INTRODUCTION
Congratulations! In purchasing the BEHRINGER XENYX you
have acquired a mixer whose small size belies its incredible
versatility and audio performance.
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:
s 130 dB dynamic range for an incredible amount of headroom
s A bandwidth ranging from below 10 Hz to over 200 kHz for
crystal-clear reproduction of even the finest nuances
s The extremely low-noise and distortion-free circuitry
guarantees absolutely natural and transparent signal
reproduction
s They are perfectly matched to every conceivable
microphone with up to 60 dB gain and +48 volt phantom
power supply
s They enable you to use the greatly extended dynamic range
of your 24-bit/192-kHz HD recorder to the full, thereby
maintaining optimal audio quality
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.
Additionally, your XENYX mixing console has an
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.
The XENYX mixing consoles are equipped with a
state-of-the-art switched-mode power supply
( ). Unlike conventional circuitry an SMPS
provides an optimum supply current regardless of
the input voltage. And thanks to its considerably
higher efficiency a switched-mode power supply uses less
energy than conventional power supplies.
The FBQ Feedback Detection System integrated
into the graphic EQ of your 1832FX is one of this
mixer’s most outstanding features.
This ingenious circuitry lets you immediately
recognize and eliminate feedback frequencies. The FBQ
Feedback Detection System uses the LEDs in the frequency
band faders of the graphic EQ to indicate the critical frequencies.
This way, what once used to be a labor-intensive search for
feedback frequencies is now an activity that even a child could
master.
We have added another useful feature to the XENYX
1832FX: the Voice Canceller.
The Voice Canceller is a filter circuitry that filters out
vocal portions from a track. Therefore, this mixing console is
4
ideally suited for use as a karaoke machine. This feature is also
an optimal solution for singers who need accompanying music
for their rehearsals.
The USB interface supplied with the unit is a perfect match for
the XENYX Series and serves as a powerful recording interface
to your PC or MAC®. It supports the digital transmission of signals
on up to four channels with max. 48 kHz and extremely low
latency. When wired to the CD/TAPE INPUT and OUTPUT
connectors, the interface transfers the stereo mix from the
console directly to a computer. Both the recording signal and the
playback signal from the computer can be monitored at the same
time. In this way, you can use several recording runs to produce
complete multi-track recordings.

1.1 General mixing console functions

A mixing console fulfils three main functions:
s
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.
Signals fed into the mixer using a DI-box ( irect njection) or
the output of a sound card or a keyboard, often have to be
adjusted to the operating level of your mixing console.
Using the equalizers found in each channel strip, you can
simply, quickly and effectively adjust the way a signal
sounds.
In addition to the effects processor contained in your mixer,
using the insert connectors on the mono channels and
both aux busses lets you insert additional signal processors
into your signal path.
s
Individual signals adjusted at each channel strip are laid
out at the aux sends and returns, and are either fed into
external effects processors or fed back to the internal
effects processor. Then, the signals are brought back into
the main mix either via the aux return connectors or via
direct internal wiring. The mix for the on-stage musicians is
also created using the aux sends (monitor mix). Similarly,
for example, signals for recording equipment, power ampli-
fiers, headphones and 2-track outputs can also be taken.
