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.
A mixing console fulfils three main functions:
The interface of BEHRINGER mixing consoles is optimized for these tasks enabling you to easily keep track of the signal path.
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 http://behringer.com, where you'll find explanations of e.g. effects and dynamics applications.
Your mixing console was carefully packed in the factory 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.
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.

This chapter describes the various control elements of your mixing console. All controls, switches and connectors will be discussed in detail.
Fig. 2.1: Connectors and controls of mic/line inputs
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 gain as is typically known only from costly outboard preamps.
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.
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).
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.
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 effect. The adjacent LED with light when the effect is engaged.
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.
Fig. 2.2: The equalizer of the input channels
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.
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.
AUX 1 (MON)
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.
PRE
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.
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.
MUTE/ALT 3-4
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 MUTE LED indicates that the relevant channel is diverted to the submix (Alt 3-4 bus).
CLIP-LED
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.
SOLO
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 "Level meters and monitoring").
The channel fader determines the level of the channel signal in the main mix (or submix).
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).
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.
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.
BAL
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.
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.
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.
AUX SEND 1 (MON)
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.
AUX SEND 2 (FX)
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.
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.
Fig. 2.7: Aux send connectors
AUX SEND 1
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.
AUX SEND 2
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.
Fig. 2.8: Stereo aux return connectors
STEREO AUX RETURN 1
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.
STEREO AUX RETURN 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.
Fig. 2.9: Stereo aux return controls
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.
STEREO AUX RETURN MON
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.
STEREO AUX RETURN 2 (FX)
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.
MAIN MIX/ALT 3-4
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).
Fig. 2.10: 2-track connectors
CD/TAPE INPUT
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.).
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.
Fig. 2.11: Control room/phones section, level meter
CD/TAPE
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.
MAIN MIX
The MAIN MIX switch sends the main mix signal to the above-mentioned outputs and to the level meter.
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 any further processing. At the same time, this switch disables the main mix to tape output link.
POWER
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.
LEVEL METER
The high-precision level meter accurately displays the appropriate signal level.
LEVEL SETTING:
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.
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.
MODE (1204FX only)
The MODE switch determines whether the channels' SOLO switch operates as PFL (Pre Fader Listen) or as solo (Solo In Place).
PFL
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.
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".
PFL (1204FX only)
The PFL LED indicates that the peak meter is set to PFL mode.
Fig. 2.12: PHONES connector
PHONES
You can connect headphones to this ¼" TRS connector. The signal on the PHONES connection is sourced from the control room output.
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.
Fig. 2.14: Main mix outputs, Alt 3-4 outputs and control room outputs
MAIN OUTPUTS
The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors with a nominal level of +4 dBu.
ALT 3-4 OUTPUTS
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.
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.
USB INPUT/OUTPUT
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 behringer.com.
Fig. 2.16: Voltage supply and fuse
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.
IEC MAINS RECEPTACLE
The mains connection is via a cable with IEC mains connector. An appropriate mains cable is supplied with the equipment.
POWER
Use the POWER switch to power up the mixing console.
PHANTOM
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!
SERIAL NUMBER
Please note the important information on the serial number given in "Online registration" chapter.
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.
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.
LEVEL
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.
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.
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.
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.
Fig. 4.1: ¼" TS connector for foot switch
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).
