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.  
!
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.  
Please note that all units must be properly grounded. For your own  
safety, you should never remove any ground connectors from electrical  
devices or power cables, or render them inoperative.  
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. 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.  
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 Mono channels  
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  
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.  
MIC  
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 2.1.3 Aux sends  
gain as is typically known only from costly outboard preamps.  
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”.  
LINE IN  
Each mono input also features a balanced line input on a ¼" connector.  
Unbalanced devices (mono jacks) can also be connected to these inputs.  
Fig. 2.3: The AUX SEND controls in the channel strips  
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!  
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.  
LOW CUT  
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).  
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.  
GAIN  
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.  
Both aux sends are mono, are sourced after the equalizer and offer up  
to +15 dB gain.  
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.  
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.  
Turn the COMP knob clockwise to add more compression effect. The adjacent LED

XENYX 1204USB/X1204USB User Manual  
AUX 1 (MON)  
SOLO  
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”).  
PRE  
When the PRE switch is pressed, aux send 1 is sourced pre-fader.  
The channel fader determines the level of the channel signal in the main mix  
(or submix).  
AUX 2 (FX)  
2.2 Stereo channels  
The aux send labeled FX is for sending to effects devices and is thus set up to  
be post-fader.  
2.2.1 Channel inputs  
In the X1204USB, the FX send is routed directly to the built-in effects processor.  
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.  
LEVEL  
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  
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.  
Fig. 2.4: Panorama and routing controls  
PAN  
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.  
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.  
MUTE/ALT 3-4  
2.2.4 Routing switch, solo and channel fader  
BAL  
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.  
MUTE-LED  
The function of the BAL(ANCE) control corresponds to the PAN control in the  
mono channels.  
The MUTE LED indicates that the relevant channel is diverted to the submix  
(Alt 3-4 bus).  
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.  
CLIP-LED  
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.  
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.

Fig. 2.6: AUX SEND controls of the main section  
Fig. 2.8: Stereo aux return connectors  
A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on  
the corresponding channel.  
STEREO AUX RETURN 1  
AUX SEND 1 (MON)  
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.  
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  
AUX SEND 1.  
You can also use these connectors as additional line inputs.  
AUX SEND 2 (FX)  
STEREO AUX RETURN 2  
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.  
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.  
SOLO  
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.  
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 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).  
If you wish to use the internal effects processor, no connectors should  
be plugged into STEREO AUX RETURN 2.  
2.3.2 Aux send connectors 1 and 2  
2.3.4 Stereo aux return  
Fig. 2.7: Aux send connectors  
AUX SEND 1  
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  
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.

STEREO AUX RETURN MON  
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.  
Fig. 2.11: Control room/phones section, level meter  
You can now use the STEREO AUX RETURN MON control to adjust the level of the  
effects signal routed to the monitor mix.  
CD/TAPE  
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 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.  
STEREO AUX RETURN 2 (FX)  
ALT 3-4  
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.  
Similarly, the ALT 3-4 switch routes the signal from the Alt 3-4 bus to the same  
path for monitoring purposes.  
MAIN MIX/ALT 3-4  
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).  
The MAIN MIX switch sends the main mix signal to the above-mentioned  
outputs and to the level meter.  
2.3.5 Tape input / tape output  
PHONES/CTRL R(oom)  
Use this control to set control room output level and head-phones  
volume respectively.  
CD/TAPE TO MAIN  
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

POWER  
CD/TAPE INPUT  
The blue POWER LED indicates that the device is switched on.  
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

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.  
CD/TAPE OUTPUT  
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.  
LEVEL METER  
The high-precision level meter accurately displays the appropriate signal level.

LEVEL SETTING:  
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)  
PHONES  
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.  
PFL  
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.  
Solo  
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.  
Fig. 2.13: Alt 3-4 and main mix fader  
Use the high-precision quality faders to control the output level of the Alt 3-4  
subgroup and main mix.  
2.4 Rear view of 1204USB/X1204USB  
2.4.1 Main mix outputs, Alt 3-4 outputs and control  
room outputs  
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.  
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”.

PHANTOM  
ALT 3-4 OUTPUTS  
The PHANTOM switch activates the phantom power supply for the XLR  
connectors of the mono channels which is required to operate condenser  
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 microphones. The red +48 V LED lights up when phantom power is on. As a  
a subgroup to a further mixing console for example, or or it could be used as a rule, dynamic microphones can still be used with phantom power switched  
recording output working in tandem with the main output. This means you could on, provided that they are wired in a balanced configuration. In case of doubt,  
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.  
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.  
CONTROL ROOM OUTPUTS  
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.  
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.  
USB INPUT/OUTPUT  
SERIAL NUMBER  
Please note the important information on the serial number given in chapter 1.3.3.  
3. Digital Effects Processor  
Fig. 2.15 USB input/output  
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 behringer.com.  
2.4.2 Voltage supply, phantom power and fuse  
Fig. 3.1: Digital effects module (only X1204USB)  
24-BIT MULTI-EFFECTS PROCESSOR  
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.  
Fig. 2.16: Voltage supply and fuse  
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.  
FUSE HOLDER  
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.  
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.  
IEC MAINS RECEPTACLE  
On the following page, you will find an illustration showing how to  
connect your foot switch correctly.  
The mains connection is via a cable with IEC mains connector. An appropriate  
mains cable is supplied with the equipment.

LEVEL  
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, 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.  
PROGRAM  
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.
