1. Introduction
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.
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 fulfils three main functions:
• Signal processing: Preamplification, level adjustment, mixing of effects,
frequency equalization.
• Signal distribution: Summing of signals to the aux sends for effects
processing and monitor mix, distribution to one or several recording tracks,
power amp(s), control room and 2-track outputs.
• Mix: Setting the volume level, frequency distribution and positioning of the
individual signals in the stereo field, level control of the total mix to match
the recording devices/crossover/power amplifier(s). All other mixer functions
can be included in this main function.
The interface of BEHRINGER mixing consoles is optimized for these tasks enabling
you to easily keep track of the signal path.
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 specific issues,
please visit our website at, where you’ll find explanations
of e.g. effects and dynamics applications.
1.3 Before you get started

2. Control Elements and Connectors
2.1.2 Equalizer
This chapter describes the various control elements of your mixing console.
All controls, switches and connectors will be discussed in detail.
All mono input channels include a 3-band equalizer. All bands provide boost or
cut of up to 15 dB. In the central position, the equalizer is inactive.
2.1 Mono channels
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 effects. The result are extremely musical equalizers which, unlike simple
equalizers, cause no side effects such as phase shifting or bandwidth limitation,
even with extreme gain settings of ±15 dB.
2.1.1 Microphone and line inputs
Fig. 2.2: The equalizer of the input channels
Fig. 2.1: Connectors and controls of mic/line inputs
Each mono input channel offers 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.
The upper (HI) and the lower band (LO) are shelving filters that increase or
decrease all frequencies above or below their cut-off frequency. The cut-off
frequencies of the upper and lower band are 12 kHz and 80 Hz respectively.
The mid band is configured as a peak filter with a center frequency of 2.5 kHz.
2.1.3 Aux sends
◊ Please mute your playback system before you activate the phantom
power supply to prevent switch-on thumps being directed to your
loudspeakers. Please also note the instructions in chapter 2.4.2
“Voltage supply, phantom power and fuse”.
Each mono input also features a balanced line input on a ¼" connector.
Unbalanced devices (mono jacks) can also be connected to these inputs.
◊ Please remember that you can only use either the microphone
or the line input of a channel at any one time. You can never use
both simultaneously!
The mono channels of the mixing consoles have a high-slope LOW CUT filter for
eliminating unwanted low-frequency signal components (75 Hz, 18 dB/octave).
Use the TRIM control to adjust the input gain. This control should always be
turned fully counterclockwise whenever you connect or disconnect a signal
source to one of the inputs.
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 effect. The adjacent LED
with light when the effect is engaged.
Fig. 2.3: The AUX SEND controls in the channel strips
Aux sends take 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 and
then routed, for example, to an active monitor speaker or an external effects
device. The return from an external effect can then be brought back into the
console via the aux return connectors.
For situations which require effects processing, the aux sends are usually
switched post-fader so that the effects volume in a channel corresponds to
the position of the channel fader. If this were not the case, the effects signal
of the channel would remain audible even when the fader is turned to zero.
When setting up a monitor mix, the aux sends are generally switched to
pre-fader; i.e. they operate independently of the position of the channel fader.
Both aux sends are mono, are sourced after the equalizer and offer up
to +15 dB gain.
◊ If you press the MUTE/ALT 3-4 switch, aux send 1 is muted,
provided that it is switched post-fader. However, this does not affect
the aux send 2 of the X1204USB.
XENYX 1204USB/X1204USB User Manual
In the X1204USB, aux send 1 can be switched pre-fader and is thus particularly
suitable for setting up monitor mixes. In the 1204USB, the first aux send is
labeled MON and is permanently switched pre-fader.
The SOLO switch (X1204USB only) is used to route the channel signal to the
solo bus (Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to
monitor a channel signal without affecting the main output signal. The signal
you hear is sourced either before (PFL, mono) or after (solo, stereo) both the pan
control and the channel fader (see chapter 2.3.6 “Level meters and monitoring”).
When the PRE switch is pressed, aux send 1 is sourced pre-fader.
AUX 2 (FX)
The aux send labeled FX is for sending to effects devices and is thus set up to
be post-fader.
In the X1204USB, the FX send is routed directly to the built-in effects processor.
The channel fader determines the level of the channel signal in the main mix
(or submix).
2.2 Stereo channels
2.2.1 Channel inputs
◊ If you wish to use the internal effects processor, the STEREO AUX
RETURN 2 connectors should not be in use.
◊ X1204USB: you can also connect an external effects processor to aux
send 2, however the internal effects module will be muted.
2.1.4 Routing switch, solo and channel fader
Fig. 2.5: Stereo channel inputs and LEVEL switch
Each stereo channel has two balanced line level inputs on ¼" connectors for left
and right channels. If only the connector marked “L” is used, the channel operates
in mono. Stereo channels are designed to handle typical line level signals.
Both inputs can also be used with unbalanced jacks.
For level matching, the stereo inputs feature a LEVEL switch which selects
between +4 dBu and -10 dBV. At -10 dBV (home-recording level), the input is
more sensitive than at +4 dBu (studio level).
2.2.2 Equalizer stereo channels
Fig. 2.4: Panorama and routing controls
The PAN control determines the position of the channel signal within the stereo
image. This control features a constant-power characteristic, which means the
signal is always maintained at a constant level, irrespective of position in the
stereo panorama.
You can use the MUTE/ALT 3-4 switch to divert the channel from the main mix
bus to the Alt 3-4 bus. This mutes the channel from the main mix.
The MUTE LED indicates that the relevant channel is diverted to the submix
(Alt 3-4 bus).
The CLIP LED lights up when the input signal is driven too high. In this case,
turn down the GAIN control and, if necessary, check the setting of the channel EQ.
The equalizer of the stereo channels is, of course, stereo. The filter characteristics
and crossover frequencies are the same as those of the mono channels. A stereo
equalizer is always preferable to two mono equalizers if frequency correction of a
stereo signal is needed. There is often a discrepancy between the settings of the
left and the right channels when using separate equalizers.
2.2.3 Aux sends stereo channels
In principle, the aux sends of the stereo channels function in just the same way as
those of the mono channels. As aux send paths are always mono, the signal on a
stereo channel is first summed to mono before it reaches the aux bus.
2.2.4 Routing switch, solo and channel fader
The function of the BAL(ANCE) control corresponds to the PAN control in the
mono channels.
The balance control determines the relative proportion between the left and
right input signals before both signals are routed to the main stereo mix bus.
The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the SOLO switch and the
channel fader function in the same way as the mono channels.
XENYX 1204USB/X1204USB User Manual
2.3 Connector panel and main section
Whereas it was useful to trace the signal flow from top to bottom in order to gain
an understanding of the channel strips, we now look at the mixing console from
left to right. The signals are, so to speak, collected from the same point on each of
the channel strips and then routed to the main section all together.
The AUX SEND 2 connector outputs the signal you picked up from the individual
channels using the FX control. You can connect this to the input of an effects
device in order to process the FX bus signal. Once an effects mix is created,
the processed signal can then be routed from the effects device output back into
the STEREO AUX RETURN connectors.
2.3.1 Aux sends 1 and 2
2.3.3 Stereo aux return connectors
Fig. 2.6: AUX SEND controls of the main section
A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on
the corresponding channel.
The AUX SEND control MON acts as master control for aux send 1 and determines
the level of the summed signal. In the X1204USB, the MON control is called
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.
You can use the SOLO switch (X1204USB only) to separately monitor the aux
sends via the CONTROL ROOM/PHONES outputs and check these with the
level meters.
◊ If you want to monitor the signal of just one AUX bus, none of the other
SOLO SWITCHES should be pressed and the MODE switch must be in the
SOLO position (not pressed down).
2.3.2 Aux send connectors 1 and 2
Fig. 2.8: Stereo aux return connectors
The STEREO AUX RETURN 1 connectors generally serve as the return path for the
effects mix generated using the post-fader aux send. This is where you connect
the output signal of the external effects device. If only the left connector is used,
the AUX RETURN automatically operates in mono.
◊ You can also use these connectors as additional line inputs.
The STEREO AUX RETURN 2 connectors serve as the return path for the effects
mix generated using the FX control. If these connectors already function as
additional inputs, you can route the effects signal back into the console via a
different channel, with the added benefit that the channel EQ can be used to
adjust the frequency response of the effects return signal.
◊ In this instance, the FX control of the channel being used as an effects
return should be turned fully counterclockwise, otherwise feedback
problems could occur!
◊ If you wish to use the internal effects processor, no connectors should
be plugged into STEREO AUX RETURN 2.
2.3.4 Stereo aux return
Fig. 2.7: Aux send connectors
Fig. 2.9: Stereo aux return controls
If you use aux send 1 pre-fader, you would usually connect the AUX SEND 1
connector to monitors via a power amp (or an active monitor system). If you use
aux send 1 post-fader, proceed as described under aux send 2.
STEREO AUX RETURN 1 is a stereo control which determines the level of the
signal in the main mix. If STEREO AUX RETURN 1 is used as effects return, you can
add the effects signal to any “dry” channel signal.
◊ In this instance, the effects device should be set at 100% effect.
XENYX 1204USB/X1204USB User Manual
2.3.6 Level meter and monitoring
The STEREO AUX RETURN MON control has a special function: it can be used to
add an effect to a monitor mix. For example:
Monitor mix with effect
In this instance, the effects device should be set up as follows: AUX SEND 2 is
connected to the L/Mono input of your effects device, while its outputs are
connected to STEREO AUX RETURN 1. Connect the amplifier of your monitor
system to AUX SEND 1. The AUX SEND 1 master control determines the volume of
the monitor mix.
You can now use the STEREO AUX RETURN MON control to adjust the level of the
effects signal routed to the monitor mix.
You can easily use the headphones distribution amplifier BEHRINGER
POWERPLAY PRO HA4600/HA4700/HA8000 to provide you with four
(or eight with the HA8000) stereo headphone mixes for your studio.
The STEREO AUX RETURN 2 control determines the level of signals fed into the
AUX RETURN 2 connectors which are routed to the main mix.
The MAIN MIX/ALT 3-4 switch routes the signal connected to STEREO AUX
RETURN 2 to either main mix (not pressed) or submix (Alt 3-4, pressed).
2.3.5 Tape input / tape output
Fig. 2.11: Control room/phones section, level meter
The TAPE switch routes the signal from the TAPE IN connectors to the level meter,
the CONTROL ROOM OUT outputs and the PHONES connector this is a simple way
to check recorded signals via monitor speakers or headphones.
ALT 3-4
Similarly, the ALT 3-4 switch routes the signal from the Alt 3-4 bus to the same
path for monitoring purposes.
The MAIN MIX switch sends the main mix signal to the above-mentioned
outputs and to the level meter.
Use this control to set control room output level and head-phones
volume respectively.
Fig. 2.10: 2-track connectors
The CD/TAPE INPUT RCA connectors are provided for connecting a 2 track
machine (e.g. DAT recorder). They can also be used as stereo line input.
Alternatively, the output signal of a second XENYX or BEHRINGER ULTRALINK
PRO MX882 can also be connected. If you connect a hi-fi amplifier with a source
selection switch to the CD/TAPE INPUT, you can easily switch between additional
sources (e.g. cassette recorder, CD player, etc.).
These connectors are wired in parallel with the MAIN OUT and carry the main
mix signal (unbalanced). Connect the CD/TAPE OUTPUT to the inputs of your
recording device. The final output level can be adjusted via the high-precision
MAIN MIX fader.
◊ If you connect a compressor or a noise gate after the 2-track
output, the faders will probably not be able to create a satisfactory
fade-out effect.
When the CD/TAPE TO MAIN switch is depressed, the 2-track input is routed to
the main mix and thus serves as an additional input for tape machines. You can
also connect MIDI instruments or other signal sources here that do not require
any further processing. At the same time, this switch disables the main mix to
tape output link.
The blue POWER LED indicates that the device is switched on.
+48 V
The red “+48 V” LED lights up when the phantom power supply is switched on.
The phantom power supply is necessary for condenser microphones and is
activated using the switch on the rear of the device.
◊ Please do not connect microphones to the mixer (or the stagebox/
wallbox) while the phantom power supply is switched on.
Connect micro-phones before you switch on the power supply.
In addition, the monitor/PA loudspeakers should be muted before you
activate the phantom power supply. After switching on, wait approx.
one minute to allow for system stabilization.
The high-precision level meter accurately displays the appropriate signal level.
XENYX 1204USB/X1204USB User Manual
PFL (1204FX only)
When recording to a digital device, the recorder’s peak meter should not exceed
0 dB. This is because, unlike analog recordings, slightly excessive levels can create
unpleasant digital distortion.
The PFL LED indicates that the peak meter is set to PFL mode.
When recording to an analog device, the VU meters of the recording machine
should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to
their inertia VU meters tend to display too low a signal level at frequencies above
1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10 dB.
Snare drums should be driven to approx. 0 dB.
The peak meters of your XENYX display the level virtually independent of
frequency. A recording level of 0 dB is recommended for all signal types.
Fig. 2.12: PHONES connector
MODE (1204FX only)
The MODE switch determines whether the channels’ SOLO switch operates as
PFL (Pre Fader Listen) or as solo (Solo In Place).
You can connect headphones to this ¼" TRS connector. The signal on the PHONES
connection is sourced from the control room output.
2.3.7 Alt 3-4 and main mix fader
To activate the PFL function, depress the MODE switch. The PFL function should,
as a rule, be used for gain setting purposes. The signal is sourced pre-fader and
assigned to the mono PFL bus. In the “PFL” setting, only the left side of the peak
meter operates. Drive the individual channels to the 0 dB mark of the VU meter.
When the MODE switch is not depressed, the stereo solo bus is active. Solo is
short for “Solo In Place”. This is the customary method for listening to an
individual signal or to a group of signals. As soon as a solo switch is pressed,
all channels in the control room (and headphones) that have not been selected
are muted thereby retaining stereo panning. The solo bus can carry the output
signals of the channel pan controls, the aux sends and the stereo line inputs.
The solo bus is, as a rule, switched post-fader.
◊ The PAN control in the channel strip offers a constant power
characteristic. This means that the signal is always at a constant level,
irrespective of its position in the stereo panorama. If the PAN control
is moved fully left or right from center, the level increases by 4 dB in
that channel. This ensures that, when set in the center, the audio signal
is not louder. For this reason, with the solo function activated (Solo in
Place), audio signals from the channels with PAN controls that have not
been moved fully to the left or right are displayed at a lower volume
than in the PFL function.
As a rule, solo signals are monitored via the control room outputs and
headphones connector and are displayed by the level meters. If a solo switch is
pressed, the signals from the tape input, Alt 3-4 and main mix are blocked from
the control room outputs, the headphone connector and the level meter.

Use the high-precision quality faders to control the output level of the Alt 3-4
subgroup and main mix.

room outputs
MAIN SOLO (1204FX only)
The MAIN SOLO LED lights up as soon as a channel or aux send solo switch is
pressed. The MODE switch also has to be set at “Solo”.
Fig. 2.14: Main mix outputs, Alt 3-4 outputs and control room outputs
XENYX 1204USB/X1204USB User Manual
The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors
with a nominal level of +4 dBu.
Use the POWER switch to power up the mixing console.
The ALT 3-4 outputs are unbalanced and carry the signals of the channels that
you have assigned to this group using the MUTE switch. This can be used to route
a subgroup to a further mixing console for example, or or it could be used as a
recording output working in tandem with the main output. This means you could
record to four tracks simultaneously. The icing on the cake, so to speak, is that
you could connect Y-cables to these four outputs and then connect your 8-track
recorder in such a way that you have 2 x 4 tracks (e.g. channel 1 feeds track 1 and
track 2, etc.). In the first recording pass, you record on tracks 1, 3, 5 and 7 and in
the second pass, on tracks 2, 4, 6 and 8.
The control room output is normally connected to the monitor system in the
control room and provides the stereo mix or, when required, the solo signal.
USB input/output
The PHANTOM switch activates the phantom power supply for the XLR
connectors of the mono channels which is required to operate condenser
microphones. The red +48 V LED lights up when phantom power is on. As a
rule, dynamic microphones can still be used with phantom power switched
on, provided that they are wired in a balanced configuration. In case of doubt,
contact the microphone manufacturer!
◊ After the phantom power supply has been switched on, do not connect
microphones to the mixer (or the stagebox/wallbox). Connect the
microphones before you switch phantom power on. In addition,
the monitor/PA loudspeakers should be muted before activating the
phantom power supply. After switching on, wait approx. one minute to
allow the system to stabilize.
◊ Caution! You must never use unbalanced XLR connectors (PIN 1 and 3
connected) on the MIC input connectors if you want to use the phantom
power supply.
Please note the important information on the serial number given in chapter 1.3.3.

3. Digital Effects Processor
The XENYX mixer line has built-in USB connectivity, allowing stereo signals to
be sent to and from the mixer and a computer. The audio sent from the mixer to
a computer is identical to the MAIN MIX. Audio being sent to the mixer from a
computer can be routed to the main mix with the 2-TR/USB TO MAIN button.
Connect the USB type B plug into the USB jack on the mixer, and the other end
into a free USB port on your computer. There are no required drivers, but we
recommend that PC users install the included ASIO driver. The driver can also be
downloaded from
2.4.2 Voltage supply, phantom power and fuse
Fig. 3.1: Digital effects module (only X1204USB)
Fig. 2.16: Voltage supply and fuse
The console is connected to the mains via the cable supplied which meets the
required safety standards. Blown fuses must only be replaced by fuses of the
same type and rating.
The mains connection is via a cable with IEC mains connector. An appropriate
mains cable is supplied with the equipment.
Here you can find a list of all presets stored in the multi-effects processor.
This built-in effects module produces high-grade standard effects such as
reverb, chorus, flanger, delay and various combination effects. The integrated
effects module has the advantage of requiring no wiring. This way, the danger
of creating ground loops or uneven signal levels is eliminated at the outset,
completely simplifying the handling.
These effect presets are designed to be added to dry signals. If you move the
FX TO MAIN control, you mix the channel signal (dry) and the effect signal.
This also goes for mixing effects signals with the monitor mix. The main
difference is that the mix ratio is adjusted using the FX TO MON control. Of course,
a signal has to be fed into the effects processor via the FX control in the channel
strip for both applications.
◊ On the following page, you will find an illustration showing how to
connect your foot switch correctly.
XENYX 1204USB/X1204USB User Manual
4.2.1 Audio connections
The LED level meter on the effects module should display a sufficiently high
level. Take care to ensure that the clip LED only lights up at peak levels. If it is
lit constantly, you are overloading the effects processor and this could cause
unpleasant distortion. The FX control (AUX SEND 2) determines the level that
reaches the effects module.
Please use commercial RCA cables to wire the 2-track inputs and outputs.
You can select the effect preset by turning the PROGRAM control. The display
flashes the number of the current preset. To recall the selected preset, press the
button; the flashing stops. You can also recall the selected preset with the
foot switch.
You can, of course, also connect unbalanced devices to the balanced
input/outputs. Use either mono plugs, or ensure that ring and sleeve are
bridged inside the stereo plug (or pins 1 & 3 in the case of XLR connectors).
◊ Caution! You must never use unbalanced XLR connectors
(pin 1 and 3 connected) on the MIC inputs if you intend to use the
phantom power supply.

4. Installation
2 1
4.1 Rack mounting
The packaging of your mixing console contains two 19" rack mount wings which
can be installed on the side panels of the console.
Before you can attach the rack mount wings to the mixing console, you need to
remove the screws holding the left and right side panels. Use these screws to
fasten the two wings onto the console, being careful to note that each wing fits
a specific side. With the rack mount wings installed, you can mount the mixing
console in a commercially available 19" rack. Be sure to allow for proper air flow
around the unit, and do not place the mixing console close to radiators or power
amps, so as to avoid overheating.
◊ Only use the screws holding the mixing console side panels to fasten
1 = ground/shield
2 = hot (+ve)
3 = cold (-ve)
For unbalanced use, pin 1 and pin 3 have to be bridged
the 19" rack mounts.
4.2 Cable connections
You will need a large number of cables for the various connections to and from
the console. The illustrations below show the wiring of these cables. Be sure to
use only high-grade cables.
