XENYX 1622FX/1832FX/2222FX/2442FX


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-artcircuitry your XENYX console produces a warm analog sound that is unrivalled. With the addition of the latest digital technology thesebest-in-classconsoles combine the advantages of both analog and digital technology.

XENYX Mic Preamp

The microphone channels feature high-endXENYX Mic Preamps that compare well with costly outboard preamps in terms of sound quality and dynamics and boast the following features:

s130 dB dynamic range for an incredible amount of headroom

sA bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clearreproduction of even the finest nuances

sThe extremely low-noiseanddistortion-freecircuitry guarantees absolutely natural and transparent signal reproduction

sThey are perfectly matched to every conceivable microphone with up to 60 dB gain and +48 volt phantom power supply

sThey enable you to use the greatly extended dynamic range of your 24-bit/192-kHzHD 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-notchconsoles 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-bitA/D and D/A converters included, which gives you 100 presets producingfirst-classreverb, delay and modulation effects plus

numerous multi-effectsin excellent audio quality.

The XENYX mixing consoles are equipped with a state-of-the-artswitched-modepower supply (SMPS). Unlike conventional circuitry an SMPS provides an optimum supply current regardless of the input voltage. And thanks to its considerably

higher efficiency a switched-modepower supply uses less energy than conventional power supplies.

FBQ Feedback Detection System

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-intensivesearch for feedback frequencies is now an activity that even a child could master.

Voice Canceller

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

ideally suited for use as a karaoke machine. This feature is also an optimal solution for singers who need accompanying music for their rehearsals.

USB/Audio interface

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-trackrecordings.


+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:

sSignal processing:


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 microphone 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-safesignal 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(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 effectively adjust the way a signal sounds.

Effects mixing

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.

sSignal distribution:

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-stagemusicians is also created using the aux sends (monitor mix). Similarly, for example, signals for recording equipment, power amplifiers, headphones and2-trackoutputs can also be taken.



XENYX 1622FX/1832FX/2222FX/2442FX


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/amplifier).

The control surface of BEHRINGER mixing consoles is optimized in such a way that these functions become easy to fulfil 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 specific issues, please visit our website at 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.

1.3Before you get started

1.3.1 Shipment

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.

+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-heatingplease do not place your mixing console onhigh-temperaturedevices 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 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.

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

2.1Mono channels

2.1.1Microphone and line inputs

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-freegain 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”.


Each mono input also has a balanced line input on a 1/4" 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!



XENYX 1622FX/1832FX/2222FX/2442FX


Insert points enable the processing of a signal with dynamic processors or equalizers. They are sourced pre-fader,pre-EQandpre-auxsend. Detailed information on using insert points can be found in chapter 5.3.

+Unlike the 2442FX, the 1622FX, 1832FX and 2222FX have their insert points located on the rear of the console.


Use the TRIM control to adjust the input gain. This control should always be turned fullycounter-clockwisewhenever you connect or disconnect a signal source to one of the inputs.

The scale has 2 different value ranges: the first value range (+10 to +60 dB) refers to the MIC input and shows the amplification for the signals fed in there.

The second value range (+10 to -40dB) refers to the line input and shows its sensitivity. The settings for equipment with st andardline-levelsignals(-10dBV or +4 dBu) look like this: While the TRIM control is turned all the way down, connect your equipment. Set the TRIM 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 TRIM slightly, for-10dBV a bit more.Fine-tuningof 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).

Using the TRIM control, drive the signal to the 0-dBmark. 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. Whilefine-tuning,the equalizer should be set to neutral.


Additionally, the mono channels of the mixing consoles have a high-slopeLOW CUT filter for eliminating unwanted, lowfrequency signal components (75 Hz, 18 dB/octave).

2.1.2 Equalizer

All mono input channels have a 3-bandequalizer with semiparametric mid bands. All bands provide boost or cut of up to 15 dB. In the central position, the equalizer is off (flat).

The circuitry of the British EQs is based on the technology used in the best-knowntop-of-the-lineconsoles 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: Equalizer of the input channels

The upper (HIGH) and the lower (LOW) bands are shelving filters that increase or decrease all frequencies above or below their cut-offfrequency. Thecut-offfrequencies of the upper and lower bands are 12 kHz and 80 Hz respectively. For the mid range, the console features asemi-parametricequalizer with a filter 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 effects busses (Aux sends)

Fig. 2.3: Aux Send control MON and FX in the channel strips

Monitor and effects busses (AUX sends) source their signals via a control from one or more channels and sum these signals to a so-calledbus. 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 effects device. In the latter case, the effects return can then be brought back into the console via the aux return connectors.

All monitor and effects busses are mono, are tapped into post EQ and offer amplification of up to +15 dB.


When using effects on a channel signal, it is usual to have the aux send post fader so that the balance between effect and dry signal stays constant even when the channel fader is altered. If this were not the case, the effects signal of the channel would remain audible even when the channel fader is turned all the way down. For monitoring, the aux sends are generally pre-fader,i.e. they operate independently of the position of the channel fader.


When the PRE switch is pressed down, the associated aux send is takenpre-fader.


The aux send marked FX offers a direct route to thebuilt-ineffects processor and is thereforepost-faderandpost-mute.Please refer to chapter 4 “DIGITAL EFFECTS PROCESSOR” for detailed information.

+If you are using the built-ineffects processor, make sure that STEREO AUX RETURN 3 has nothing plugged into it (2442FX and 2222FX), otherwise the internal effects return will be muted. This is not relevant if you use the FX OUT jack to drive an external effects device.

+1622FX and 1832FX: On these consoles, the above note refers to the STEREO AUX RETURN 2 jacks as these models do not have a dedicated effect output.



XENYX 1622FX/1832FX/2222FX/2442FX

2.1.4 Routing switch, PAN, SOLO and channel fader

Fig. 2.4: The panorama and routing controls and the channel fader


The PAN control determines the position of the channel signal within the stereo image. When working with subgroups, you can use the PAN control to assign the signal to just one output, which gives you additional flexibility in recording situations. For example, when routing to subgroups 3 and 4, panning hard left will route the signal to group output 3 only, and panning hard right will route to group output 4 only.


The MUTE switch breaks the signal pathpre-channelfader, hence muting that channel in the main mix. The aux sends which are set topost-faderare likewise muted for that channel, while thepre-fadermonitor paths remain active irrespective of whether the channel is muted or not.


The MUTE LED indicates a muted channel.


The CLIP-LEDlights up when the input signal is driven too high. If this happens, back off the TRIM control and, if necessary, check the setting of the channel EQ.


The SOLO switch 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 listen to a channel signal without affecting the main output signal. The signal you hear is taken either before the pan control (PFL, mono) or after the pan and channel fader (Solo, stereo) (cf. chap. 2.3.10 “Level meters and monitoring”).

SUB (1-2and3-4)

The SUB switch routes the signal to the corresponding subgroups. The 2442FX has 4 subgroups(1-2and3-4).


The MAIN switch routes the signal to the main mix bus.

The channel fader determines the channel’s volume in the main mix (or submix).

2.2Stereo channels

2.2.1Channel inputs

Fig. 2.5: The various stereo channel inputs

Each stereo channel has two balanced line level inputs on jacks for left and right channels. Channels 9/10 and 11/12 on the 2442FX feature an additional XLR microphone jack with phantom power. If only the left jack (marked “L”) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals, and, depending on model, have a level switch (+4 dBu or -10dBV) and/or a line TRIM control. Both jack inputs will also accept unbalanced connectors.


These two control elements operate on the XLR connectors of the 2442FX, and are used to filter out frequencies below 75 Hz (LOW CUT) and to adjust microphone levels (MIC TRIM).


Use this control to adjust the line signal levels on channels 13-16(2442FX only).


For level matching, the stereo inputs on the 1622FX, 1832FX and 2222FX have a LEVEL switch to select between +4 dBu and-10dBV. At-10dBV (homerecording level), the input is more sensitive than at +4 dBu (studio level).

2.2.2 Equalizer stereo channels

The stereo channels contain a stereo EQ section. The cut-offfrequencies of the high and low bands are 12 kHz and 80 Hz respectively, while the center frequencies of thehigh-midandlow-midbands are 3 kHz and 500 Hz respectively. The HIGH and LOW controls have the same characteristics as the EQ in the mono channels. Both mid range bands are of the peak filter type. A stereo EQ is superior to two mono EQs on a stereo signal as two separate EQs will usually result in a discrepancy between left and right channels.

2.2.3 Aux sends stereo channels

In principle, the aux sends of the stereo channels function the same way as those of the mono channels. As the aux sends are mono, the send from a stereo channel is first summed to mono before it reaches the aux bus.



XENYX 1622FX/1832FX/2222FX/2442FX

2.2.4 Routing switch, solo and channel fader

Fig. 2.6: Balance control and mute switch


The BAL(ANCE) control has a similar function to the PAN control in the mono channels.

The balance control determines the levels of the left and right input signals relative to each other before both signals are routed to the left/right main mix bus (or odd/even subgroup).

The remaining control elements in the stereo channels perform the same functions as their counterparts in the mono channels (MUTE switch, MUTE and CLIP LEDs, SOLO switch, SUB and MAIN switches and channel fader).

2.3 Interface panel and main section

Where 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.

2.3.1 MON control, aux sends 1, 2 and 3 (FX)

Turning up the AUX 1 control in a channel routes the signal to the aux send bus 1.

+As the 1832FX is equipped with an additional monitor path, its first aux control in the channel strips is named MON. The console also has a dedicated master fader (MON SEND) for this aux path.

AUX SEND 1, 2 and 4

The AUX SEND 1 control governs the master send level of the mix created by the individual channel AUX 1 sends.

Likewise, the AUX SEND 2 contol is the master control for the aux 2 bus, andAUX SEND 4 controls the AUX 4 bus.

Fig. 2.7: The AUX SEND controls of the main section!


The FX control determines the signal level for effects processing, i.e. regulates the level to an external (or the internal) effects device.

1622FX and 1832FX: On these consoles, this function is performed by the AUX SEND 2 control (FX).


You can use the SOLO switch 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 should be in the SOLO position (not depressed).

2.3.2Aux send jacks

Fig. 2.8: Aux send jacks

AUX SEND jacks

The AUX SEND jack should be used when hooking up a monitor power amp or active monitor speaker system. The relevant aux path should be setpre-fader.

+ On the 2222FX, aux send 1 is hard wired aspre-faderand hence called MON. Model 1832FX has a dedicated monitor output (MON OUT jack), cf. chapter 2.3.4.

As already mentioned, the aux sends in the channels—ifsetpost-fader—canbe used to connect to external effects devices.


The AUX SEND (FX) jack carries the master aux mix (from the channel’s FX controls). You can connect this to an external effects device to process the FX bus. The processed signal can then be brought from the effects device back into the STEREO AUX RETURN jacks.

2.3.3 Stereo aux return connectors

Fig. 2.9: The aux return connectors

+On the 2222FX, 1832FX and 1622FX the STEREO AUX RETURN jacks are located on the front panel of the unit.


The STEREO AUX RETURN 1 jacks generally serve as the return for the effects mix (created using thepost-faderaux sends) by connecting the output of an external effects device. If only the left jack is connected, the AUX RETURN is automatically switched to mono.

+You can also use these jacks as additional line inputs.

All stereo aux returns are balanced, but can of course also be used with unbalanced connectors. If you use an aux send for monitoring, the associated unused stereo aux returns are available for other line level signals (e.g. keyboards).

+A signal fed into the stereo return jacks can be output via an aux send jack. More information on this can be found in chapter 2.3.5 “STEREO AUX RETURN 1/2 (TO AUX SEND)”.


The STEREO AUX RETURN FX jacks accept the effects mix



XENYX 1622FX/1832FX/2222FX/2442FX

return (created using the channel FX sends). If these jacks are already in use as additional inputs, you can route the effects signal back into the console via a different channel. The advantage of this is that you can now use that channel’s EQ on 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, do not plug any connectors into the STEREO AUX RETURN FX jacks, unless you want to tap the processed signal via the FX OUT (2222FX and 2442FX only).

2.3.4 The monitor section of the 1832FX

One of the ways that the 1832FX differs from the other models of this series is that it has a separate monitor output.

Fig. 2.10: Monitor output of the 1832FX

The first aux send (MON) on this console is used to set up the monitor mix from the channels and route it to the MON SEND fader.

Fig. 2.11: Monitor fader of the 1832FX


Press the MUTE switch to mute the monitor send.


The SOLO switch routes the monitor send to the solo bus (post-faderandpost-mute)or to the PFL bus(pre-faderandpre-mute).The position of the MODE switch in the main section determines which of the buses is selected.

2.3.5 Stereo aux return control


The STEREO AUX RETURN 1 control determines the level of this signal in the main mix. If STEREO AUX RETURN 1 is used as effects return, this will determine the level of the effects when mixed with any “dry” channel signal.

+When used in this way, the effects device should be set at 100% effect.

Fig. 2.12: Stereo aux return and stereo aux return (to aux send) controls


The two right-handSTEREO AUX RETURN controls have a special function: they can be used to add an effect to a monitor mix. An example follows (1622FX wired to an effects device):

Monitor mix with effect

In this instance, your effects device should be set up as follows: the AUX SEND 2 jack should be connected to the L/Mono input of your effects device, with its outputs coming back into the STEREO AUX RETURN 1 jacks.

Connect the AUX SEND 1 jack output to the amplifier of your monitor system. The AUX SEND 1 master control determines the overall volume of the monitor mix.

Using the STEREO AUX RETURN (TO AUX SEND) control, the effect signal can now be blended into the monitor mix.

You can easily use the headphones distribution amplifier BEHRINGER POWERPLAY PRO HA4700/HA8000 to provide four (HA8000: eight) stereo headphone mixes for your studio.

Tab. 2.1: Connectors and controls for monitor mix with effect


On consoles 1622FX and 1832FX this is the STEREO AUX RETURN 2, on consoles 2222FX and 2442FX this is theSTEREO AUX RETURN 3.



XENYX 1622FX/1832FX/2222FX/2442FX

Use the STEREO AUX RETURN FX control to determine the level of the signal routed from the AUX RETURN FX jacks to the main mix. If nothing is connected to these jacks, the output of the built-ineffects module will appear.


This switch routes the signal fed in via the STEREO AUX RETURN FX jacks either to the main mix (not pressed) or to the submix (pressed).

On the 2442FX you can select which subgroup the signal is assigned to (switches 1-2 /3-4,to the right of MAIN MIX / TO SUBS).


Additionally, this model allows you to route the aux returns together to the solo bus and the PFL bus. The LED lights up when Solo is on.


This control behaves the same way as the other stereo aux returns. Additionally, it provides for a simple monitor path using the switch PHONES/CTRL ROOM ONLY.


Use this switch to route the signal appearing at the AUX RETURN 4 jacks to the control room and headphones outputs.

2.3.6 Supplement to 1832FX

The 1832FX has a stereo fader for the AUX RETURN FX and offers a variety of routing options: MUTE disables the effect return (but not PFL of course!), SOLO routes it to the Solo or PFL busses, SUB to the subgroups and MAIN to the main mix.

The MON switch routes the signals appearing at the AUX RETURN 2 jacks to the monitor path, along with the monitor signals from the channels.

If you wish to route the effect signal to the monitor mix, you can also switch aux 1 to pre-fader,drive the effect device from the aux 1 output and return the effect signal via AUX RETURN 2 to the monitor signal.

2.3.7 XPQ Surround function (1832FX only)

Fig. 2.14: Control elements of the surround function

The XPQ surround function can be enabled/

disabled with the XPQ TO MAIN switch. This is abuilt-ineffect that widens the stereo width, thus making the sound more lively and trans-

parent. Use the SURROUND control to determine the intensity of this effect.


Here, you have a filter circuitry that lets you almost entirely remove the vocal portion of a recording. The filter is constructed in such a way that voice frequencies are targeted without majorly affecting the rest of the signal. Additionally, the filter seizes

only the middle of the stereo image, exactly there where the vocals are typically located.

+Connect the signal sources you wish to process using the Voice Canceller to the CD/TAPE INPUT connectors. The Voice Canceller circuitry is not available for other inputs.

Possible applications for the Voice Canceller are obvious: you can very simply stage background music for Karaoke events. Of course, you can also do this at home or at your rehearsal room before you hit the stage. Singers with their own band can practice singing difficult parts using a complete playback from a tape player or a CD, thus minimizing rehearsal time.

2.3.8 CD/Tape input, CD/tape output

Fig. 2.15: 2-trackconnectors and lamp socket


The CD/TAPE INPUT jacks (RCA) are designed to accept a2-trackrecorder (e.g. DAT recorder), or they can be used as stereo line input. The output signal of a second XENYX or the BEHRINGER ULTRALINK PRO MX882 can also be connected here. If you connect the output of ahi-fiamplifier (with a source selection switch) to the CD/TAPE INPUT, you can easily listen to additional sources (e.g. cassette recorder, MD player, sound card, etc.).

Using the voice canceller function (1832FX only), you can process all signals being brought into your mixing console via these connectors.


These connectors are wired in parallel to the MAIN OUT and carry the main mix signal (unbalanced). Connect this to the inputs of your recording device. The final output level can be adjusted
