1. Introduction

XENYX Mic Preamp

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 full, 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.

Multi-eects processor

Additionally, your XENYX mixing console has an eects processor
with 24-bit A/D and D/A converters included, which gives you
16presets producing rst-class reverb, delay and modulation eects
plus numerous multi-eects in excellent audio quality.

The XENYX mixing consoles are equipped with a state-of-the-art
switched-mode power supply (SMPS). Unlike conventional circuitry an

SMPS provides an optimum supply current regardless of the input
voltage. And thanks to its considerably higher eciency a switched-mode power
supply uses less energy than conventional power supplies.

 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 faders and phones control in the main section
fully down before you switch on the unit. Always be careful to set the
appropriate volume.

1.1 General mixing console functions

A mixing console fulls three main functions:

• Signal processing:

Preamplication

Microphones convert sound waves into voltage that has to be amplied
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 amplied 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 amplication
using an amplier 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. Inter ference
that could take place at the preamplication level could aect 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
eectively adjust the way a signal sounds.

FBQ Feedback Detection System

The FBQ Feedback Detection System integrated into the graphic EQ
of your X1832USB 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.

Voice Canceller

We have added another useful feature to the XENYX X1832USB:
theVoice Canceller.

The Voice Canceller is a lter circuitry that lters out vocal portions
from a track. Therefore, this mixing console is ideally suited for use as a
karaoke machine. This feature is also an optimal solution for singers who need
accompanying music for their rehearsals.

Eects mixing

In addition to the eec ts 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.

• Signal distribution:

Individual signals adjusted at each channel strip are laid out at the aux
sends and returns, and are either fed into external eects processors or fed
back to the internal eects 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 ers, headphones and 2-track outputs can also be taken.

6 XENYX X2442USB/X2222USB/X1832USB/X1622USB User Manual

• 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/amplier).

The control surface of BEHRINGER mixing consoles is optimized in such a way
that these functions become easy to fulll while the signal path remains
simple to follow.

1.2 The user’s manual

The user’s manual is designed to give you both an overview of the controls,
aswell as detailed information on how to use them. In order to help you
understand the links between the controls, we have arranged them in groups
according to their function. If you need to know more about specic issues,
please visit our website at http://behringer.com. Additional information and
explanations about various music industry/audio technology terminology can be
found on individual product pages as well as in the glossary.

◊ The block diagram supplied with the mixing console gives you an

overview of the connections between the inputs and outputs, as well
as the associated switches and controls.

1.3.3 Online registration

2. Control Elements and Connectors

This chapter describes the various control elements of your mixing console.
Allcontrols, switches and connectors will be discussed in detail.

2.1 Mono channels

1.3 Before you get started

1.3.1 Shipment

Your mixing console was carefully packed in the factor y to guarantee safe
transport. Nevertheless, we recommend that you carefully examine the
packaging and its contents for any signs of physical damage, which may have
occurred during transit.

◊ If the unit is damaged, please do NOT return it to us, but notify your

dealer and the shipping company immediately, otherwise claims for
damage or replacement may not be granted.

1.3.2 Initial operation

Be sure that there is enough space around the unit for cooling purposes and to
avoid over-heating please do not place your mixing console on high-temperature
devices such as radiators or power amps. The console is connected to the
mains via the supplied cable. The console meets the required safety standards.
Blownfuses must only be replaced by fuses of the same type and rating.

◊ Please note that all units must be properly grounded. For your own

safety, you should never remove any ground connec tors from electrical
devices or power cables, or render them in operative.

◊ Please ensure that only qualified people install and operate the

mixing console. During installation and operation, the user must have
sufficient electrical contact to earth, otherwise electrostatic discharges
might affect the operation of the unit.

2.1.1 Microphone and line inputs

X2222USB X2442USB

Fig. 2.1: Connector s and controls of mic /line inputs

7 XENYX X2442USB/X2222USB/X1832USB/X1622USB User Manual

MIC

Each mono input channel oers a balanced microphone input via the XLR
connector and also features switchable +48 V phantom power supply for
condenser microphones. The XENYX preamps provide undistorted and noise-free
gain as is typically known only from costly outboard preamps.

◊ Please mute your monitor system before you switch on phantom

power. Otherwise potentially damaging thumps will be sent to
your speakers. Please also note the instructions in chapter 5.5
“Voltage supply, phantom power and fuse”.

LINE IN

Each mono input also has a balanced line input on a ¼" jack. You can also connect
unbalanced devices using mono jacks to these inputs.

◊ Please remember that you can use either the microphone input or the

line input of a channel, but not both at the same time!

INSERT

◊ Insert points enable the processing of a signal with dynamic processors

or equalizers. They are sourced pre-fader, pre-EQ and pre-aux send.
Detailed information on using insert points can be found in chapter 5.3.

◊ Unlike the X2442USB, the X1622USB, X1832USB and X2222USB have

their insert points located on the rear of the console.

GAIN

Use the GAIN control to adjust the input gain. This control should always be
turned fully counter-clockwise whenever you connect or disconnec t a signal
source to one of the inputs.

The scale has 2 dierent value ranges: the rst value range (+10 to +60 dB)
refers to the MIC input and shows the amplication for the signals fed in there.

The second value range (+10 to -40 dB) refers to the line input and shows its
sensitivity. The settings for equipment with st andard line-level signals (-10dBV
or +4 dBu) look like this: While the GAIN control is turned all the way down,
connect your equipment. Set the GAIN control to the external devices’ standard
output level. If that unit has an output signal level display, it should show 0 dB
during signal peaks. For +4dBu, turn up GAIN slightly, for -10 dBV a bit more.
Fine-tuning of a signal being fed in is done using the level meter. To route the
channel signal to the level meter, you have to press the SOLO switch and set the
MODE switch in the main section to PFL (LEVEL SET).

2.1.2 Equalizer

All mono input channels have a 3-band equalizer with semi-parametric mid
bands. All bands provide boost or cut of up to15 dB. In the central position,
theequalizer is o (at).

The circuitry of the British EQs is based on the technology used in the best-known
top-of-the-line consoles and providing a warm sound without any unwanted
side eects. The result are extremely musical equalizers which, unlike simple
equalizers, cause no side eects such as phase shifting or bandwidth limitation,
even with extreme gain settings of ±15 dB.

All Models

Fig. 2.2: Equalizer of the input channels

The upper (HIGH) and the lower (LOW) bands are shelving lters that increase
or decrease all frequencies above or below their cut-o frequency. The cut-o
frequencies of the upper and lower bands are 12 kHz and 80Hz respectively.
Forthe mid range, the console features a semi-parametric equalizer with a
lter quality (Q) of 1 octave, tunable from 100 Hz to 8 kHz. Use the MID control
to set the amount of boost or cut, and the FREQ control to determine the
centralfrequency.

2.1.3 Monitor and eects busses (Aux Sends)

Using the GAIN control, drive the signal to the 0-dB mark. This way you have
a vast amount of drive headroom for use with very dynamic signals. TheCLIP
display should light up only rarely, preferably never. While ne-tuning,
theequalizer should be set to neutral.

LOW CUT

Additionally, the mono channels of the mixing consoles have a high-slope
LOW CUT lter for eliminating unwanted, low-frequency signal components
(75Hz, 18 dB/octave).

COMPRESSOR

Each mono channel features a built-in compressor which lowers the dynamic
range of the signal and increases its perceived loudness. The loud peaks are
squashed down and the quiet sections are boosted.

Turn the COMP knob clockwise to add more compression eect. The adjacent LED
with light when the eect is engaged.

X1622USB X2442USB

Fig. 2.3: Aux Sen d control MON and FX in t he channel strip s

Monitor and eects busses (AUX sends) source their signals via a control from
one or more channels and sum these signals to a so-called bus. This bus signal
is sent to an aux send connector (for monitoring applications: MON OUT) and
then routed, for example, to an active monitor speaker or external eects device.
Inthe latter case, the eects return can then be brought back into the console via
the aux return connectors.

All monitor and eects busses are mono, are tapped into post EQ and oer
amplication of up to +15 dB.
