1. Introduction  
FBQ Feedback Detection System  
Make sure that children cannot play unsupervised with the unit or  
its packaging.  
Please ensure proper disposal of all packing materials.  
One of the most outstanding features of this console is the  
FBQ Feedback Detection System, which is part of the graphic  
equalizer. This ingenious circuit makes it possible to detect and  
subsequently eliminate feedback frequencies very quickly.  
FBQ increases the brightness of the EQ fader LEDs for the frequency bands where  
feedback is occurring. What used to be a tedious search for feedback frequencies  
is now mere child’s play.  
1.1.2 Initial operation  
Ensure adequate air supply and to avoid overheating do not place the unit  
near radiators etc.  
Blown fuses must be replaced by fuses of the correct rating!  
Please refer to the “Specifications” section for the applicable rating.  
For connection to the mains use the enclosed power cord with cold connector  
which complies with the relevant safety regulations.  
XENYX Mic Preamps  
The microphone channels feature high-end XENYX Mic Preamps  
that compare well with costly outboard preamps in terms of sound  
quality and dynamics and boast the following features:  
Please make sure that all devices are properly grounded. For your own  
safety, never remove or disable the ground conductors from the devices  
or on the power cords. The unit must always be connected to the mains  
outlet with a protective grounding connection.  
130 dB dynamic range for an incredible amount of headroom  
A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear  
reproduction of even the finest nuances  
We would like to point out that high volume levels may damage your  
hearing and/or your headphones/loudspeakers. To avoid switch-on/off  
thumps from the console and any downstream devices, always make  
sure that your power amp(s) or active speakers are the last components  
that are switched on and the first to be switched off. Always make sure  
that the appropriate volume is set.  
The extremely low-noise and distortion-free circuitry guarantees absolutely  
natural and transparent signal reproduction  
They are perfectly matched to every conceivable microphone with up to  
60 dB gain and +48 volt phantom power supply  
Important notes concerning installation  
They enable you to use the greatly extended dynamic range of your  
24-bit/192-kHz HD recorder to the full, thereby maintaining optimal  
audio quality  
The sound quality may diminish within the range of powerful  
broadcasting stations and high-frequency sources. Increase the  
distance between the transmitter and the device and use shielded  
cables for all connections.  
“British EQ”  
The equalizers used for the XENYX Series are based on the legendary circuitry of  
top-notch consoles made in Britain, which are renowned throughout the world  
for their incredibly warm and musical sound character. Even with extreme gain  
settings these equalizers ensure outstanding audio properties.

2. Control Elements and  
Connections  
The second scale has a gain from +10 to -40 dBu for the line input.  
For devices with a nomal line output level of-10 dBV or +4 dBu the setting  
is as follows: with GAIN fully counter-clockwise connect the external device  
and adjust the output level recommended by the manufacturer. If available,  
the output level display of the external device should read 0 dB with signal  
peaks. For +4 dBu increase GAIN, for -10 dBV increase it further. The fine-  
tuning can be done with a music signal and the LEVEL SET LED, which will  
illuminate when the optimum operating level has been set.  
This chapter describes the various control elements of your mixing console.  
All controls and connections are explained in full detail.  
2.1 Mono input channels  
2.1.1 Microphone and line inputs  
[5] Mono channels are equipped with a high-slope LOW CUT filter eliminating  
unwanted low-frequency signals, such as floor rumble (18 dB/oct., -3 dB  
at 80 Hz).  
2.1.2 Equalizer  
[1]  
All mono input channels are equipped with a 3-band equalizer. The maximum  
boost/cut of the individual bands is 15 dB, in mid position the EQ is set to neutral.  
[2]  
[3]  
[6]  
[7]  
[4]  
[5]  
[8]  
Fig. 2.1: Connectors and controls of the mic/line inputs  
Fig. 2.2: Equalizer section of input channels  
[1] Each mono input channel is equipped with a balanced microphone input  
on an XLR connector, which provides +48 V phantom power for condenser  
microphones at the touch of a button (see rear panel).  
[6] The HIGH control in the EQ section controls the high frequency range of  
the respective channel. It is a shelving-type filter which can boost or cut all  
frequencies above a fixed frequency (12 kHz).  
Be sure to switch off your audio system before you activate the  
phantom power supply to prevent audible switch-on thumps from  
reaching your monitor speakers. Please also note the information given  
in chapter 2.11 “Rear panel”.  
[7] The MID control allows you to raise or lower the mid-range level. It is a semi-  
parametric peak filter, which boosts or cuts the frequency range around a  
variable mid-range frequency. Use the FREQ control to select the mid-range  
frequency from 100 Hz to 8 kHz. Then use the MID control to boost or cut the  
selected frequency range.  
[2] Each mono input also has a balanced line input on ¼" TRS connectors.  
Of course, these inputs can also be used with unbalanced plugs  
(¼" TS connector).  
[8] The LOW control boosts or cuts the low-frequency range. Like the HIGH filter  
it is a shelving-type filter, which raises or lowers the level of all frequencies  
below a specific frequency (80 Hz).  
[3] The INSERT I/O connector is used to process a signal with dynamic  
processors or equalizers. This insert point isprefader, pre-EQ and  
pre-aux send.  
2.1.3 Aux/FX send buses  
Unlike reverb and other effects, which are usually added to the dry signal,  
dynamic processors process the entire signal. So, aux send buses are not the  
best solution here. Instead, dynamic processors and equalizers are inserted  
into the signal path. Once processed, the signal then re-enters the mixing  
console at the same point where it left. Signal interruption only occurs if  
a plug is inserted into the corresponding jack (¼" stereo plug: tip = signal  
output, ring = input). All mono input channels are equipped with insert  
points. They can also be used as pre-EQ direct outputs, without signal  
flow interruption. For this you need a cable with a ¼" TS connector on the  
recorder/effects processor end, and a bridged stereo ¼" TRS connector on  
the console end (tip and ring interconnected).  
Aux sends enable you to take the signals from one or multiple channels and  
collect them on one bus. This signal is then present at one of the aux send jacks,  
from where it can be routed to an active monitor speaker or external effects  
device, for example. The FX returns are subsequently used as a return bus for the  
processed signal.  
[9]  
[10]  
[11]  
[4] The GAIN control adjusts the input gain. Be sure to set this control fully  
counter-clockwise before you connect or disconnect a signal source to or  
from one of the inputs.  
GAIN has a dual scale: the first scale has a gain from +10 to +60 dB for  
the MIC input.

EURODESK SX2442FX/SX3242FX User Manual  
[9] On each channel, the AUX 1 and AUX 2 controls allow you to determine the  
level of the aux signals sent from the channel. The main aux send signal  
comprising the aux send signals from all channels can then be adjusted  
with the corresponding master AUX SEND controls [51], and is present at the  
AUX SEND outputs [52]. Both aux sends are mono, post-EQ, with a gain of up  
to +15 dB.  
[15] The SOLO switch routes the channel signal to the solo bus (Solo In Place)  
or the PFL bus (Pre Fader Listen). Thus, you can monitor a channel signal  
without affecting the main output signal. The signal to be monitored is  
taken either pre (PFL, mono) or post-panorama control (Solo, stereo) and  
post-channel fader (depending on the position of the SOLO/PFL switch [40]).  
[16] The SUB switch routes the signal to the respective subgroups.  
Your EURODESK features 4 subgroups (1-2 and 3-4). With the PAN control on  
the input channel (see [12]) you can determine to which of the two groups the  
signal is routed (hard left: sub 1 or 3, hard right: sub 2 or 4).  
[10] Press the PRE switch to set all aux sends to pre-fader. In this case,  
the volume of the aux signals is no longer dependent on the fader position,  
so you can create completely independent monitor mixes.  
For most applications when controlling an external effects device from [17] The MAIN switch routes the signal to the main mix.  
one of the aux buses, the aux sends must be set post-fader, so that  
the effect volume in a channel depends on the position of the channel  
fader. Otherwise, the effect signal would still be audible, even if the  
channel was turned down completely. For this type of application it is  
advisable to leave the PRE switch out (= not pressed).  
[18] The channel fader governs the level of the channel signal as part of the main  
mix (or submix).  
2.2 Stereo channels  
[11] FX 1 and FX 2 controls provide a direct route to the built-in effects processor. 2.2.1 Channel inputs  
Additionally, they can be used to control an external effects unit, via the  
FX SEND 1 and 2 outputs (similar to the AUX SEND 1 and 2 jacks). To ensure  
that the internal effects processor and the FX SEND outputs actually get a  
signal, the corresponding FX control must not be set fully counter-clockwise  
(-oo), and the master FX SEND (see [60]) must be turned up. The FX buses are  
hard wired post-fader.  
[19]  
Please also read chapter 2.10 “Effects section” and  
3 “Digital effects processor”.  
[20]  
2.1.4 Mono channel fader and further control elements  
Fig. 2.5: Stereo channel inputs  
[12]  
[19] Each stereo channel is equipped with two balanced line-level inputs on  
¼" TRS connectors for the left and right channels. The channels can also  
process mono signal, as long as you use the “LEFT” jack only.  
[13]  
[20] All stereo channel strips have a GAIN control for gain adjustment. Its scale  
ranges from +20 to -20 dB and allows you to adapt the input level to the  
line inputs.  
[14]  
[15]  
2.2.2 Stereo channel equalizer

[17]  
[18]  
[21]  
Fig. 2.4: Channel fader, pan control, mute button, etc.

EURODESK SX2442FX/SX3242FX User Manual  
2.2.3 Stereo channel aux/FX send buses  
2.4 Subgroups 1 - 4  
Basically, the aux and FX buses on the stereo channels are the same as on the  
mono channels. Since aux buses are always mono, the signal from a stereo  
channel is first mixed to mono before it is routed to the aux bus.  
[26]  
2.2.4 Stereo channel fader and other control elements  
[27]  
[22]  
[25]  
Fig. 2.9: Subgroups 1 - 4  
The EURODESK has 4 subgroups enabling you to create mono or stereo mixes  
from multiple input signals. Subgroups are controlled from one (mono) or two  
(stereo) subgroup faders. Additionally, it is possible to connect the subgroup  
outputs as tape sends to a multi-track recorder.  
[25] The subgroup faders determine the volume of the subgroup signal at the  
subgroup output [28]. Depending on the position of the routing switch [27]  
you can thus control the subgroup volume in the main mix.  
[26] The SOLO switch routes the subgroup signal to the solo bus (Solo In Place)  
or PFL bus (Pre Fader Listen), so that you can monitor the subgroup signal  
without affecting the main or sub output signals. The signal to be monitored  
is taken either pre (PFL, mono) or post-subgroup fader (Solo, stereo),  
depending on the position of theSOLO/PFL switch [40]). The SOLO LED  
illuminates when the SOLO switch is pressed.  
Fig. 2.7: Channel fader, balance control, mute switch, etc.  
[22] The BAL(ANCE) control has the same function as the PAN control on  
the mono channels. It determines the relative volume of the left and  
right input signals before they are routed to the stereo main mix bus  
(or to two subgroups).  
[27] Use the routing switches for the subgroups to send the subgroup signal to  
the main mix. You can route it to the left stereo side (=LEFT pressed), to the  
right stereo side (=RIGHT pressed) or to both (=LEFT and RIGHT pressed).  
For example, when you have created a stereo submix using subgroups  
1 and 2, be sure to route group 1 to the left and group 2 to the right side  
to maintain proper stereo positioning. If it is a mono submix with just one  
subgroup, route it to the left and right sides of the main mix to make the  
signal audible on both sides.  
All other control elements of the stereo channels work in the same ways as their  
counterparts on the mono channels (faders, MUTE switches, etc.).  
Please note: When you route a stereo channel to the subgroups  
using the SUB switches, please be sure to set the BAL control to  
its mid position, so that the signal is sent to two subgroups and  
remains stereo.  
2.3 Stereo channels 21-24 (SX2442FX) or  
29-32 (SX3242FX)  
[28]  
[23]  
Fig. 2.10: Subgroup outputs 1 - 4  
[28] These four SUBGROUP OUT (puts) carry the signals of the individual  
subgroups. For multi-tracking connect the outputs to the inputs of a  
multi-track recorder (see chapter 4.1 “Studio set-up”).  
[24]  
Fig. 2.8: Auxiliary stereo channels  
Your EURODESK has two stereo channels with an aux send section [23]  
(AUX 1 and AUX 2) and one LEVEL control. [24] For these channels, the aux buses  
are hard-wired to pre-fader and are therefore particularly useful for monitoring.  
They have no routing switches and are always sent to the main mix. Like the  
normal stereo channels they have two line-level inputs on ¼" TRS connectors  
for the left and right channels, and a SOLO switch.  
Similar to the CD/TAPE inputs (see [49]) the auxiliary stereo channels can  
be connected to CD players, tape decks, etc., for example, to feed in  
playback material.

2.5 Mono out section for  
subwoofer applications  
[33] Use this high-precision MAIN fader to control the output level of the main mix.  
Using this auxiliary mono output you can route the main mix signal to a separate  
power amp. The tunable low-pass filter allows you to limit the signal content to  
the low-frequency range to get a perfect subwoofer signal. This signal is mono  
because very low frequencies disperse quickly, so there would be no benefit to  
position this signal in the stereo mix.  
[34]  
Fig. 2.14: XLR main out connectors  
[30]  
[31]  
[29]  
[34] The MAIN OUT(puts) are balanced XLR connectors with a nominal operating  
level of +4 dBu and provide the main mix signal.  
[36]  
[35]  
Fig. 2.15: Main out connectors and main insert  
[35] The MAIN OUT ¼" TRS connectors outputs also provide the main mix signal.  
Fig. 2.11: Mono out fader and low-pass filter  
[36] Like the channel inserts, the MAIN INSERT connectors can be used to  
connect a dynamics processor or equalizer for further processing of the  
mix signal. The MAIN INSERT refers to the Main Outs (XLR and ¼" TRS  
connectors), the MONO OUT (see [32]) and, if the MAIN switch in the  
PHONES/CONTROL ROOM section is pressed, also to the PHONES/CTRL ROOM  
output (see [46]).  
[29] The MONO fader controls the volume of the signal present at the  
MONO OUT (see [32]).  
[30] The FREQ control adjusts the cut-off frequency of the low-pass filter  
(30 to 200 Hz). Frequencies above cut-off are filtered out when activated.  
[31] Use the LOW PASS FILTER switch to activate the filter function (LED illuminates).  
[37]  
[38]  
[39]  
[32]  
fig. 2.12: Mono out connector  
[32] The MONO OUT connector provides the line-level mono signal for  
connection to the inputs of a power amp or active speaker. You can also use  
this output as a monitor bus, e.g. to connect a headphone amplifier. In this  
case, the signal should of course not be limited by the low-pass filter.  
2.6 Main out section  
[40]  
Fig. 2.16: Level meter  
[37] The red “+48 V” LED illuminates when phantom power is on.  
Phantom power is required for the operation of condenser microphones,  
and can be switched on with the corresponding switch on the rear of  
the console.  
[38] The POWER LED is illuminated when the console is switched on.  
[39] The high-precision level meter accurately indicates the output signal level.  
For example, when you press the SOLO switch on one of the input channels,  
its signal level will be displayed here, either pre-fader (PFL) or post-fader  
(SOLO), depending on the position of the SOLO/PFL switch (see [40]). In PFL  
mode only the left display is active, because the PFL signals are mono.  
[33]

10 EURODESK SX2442FX/SX3242FX User Manual  
[40] The SOLO/PFL switch determines whether the monitored signal is pre  
(PFL) or post-fader (SOLO) after pressing the SOLO/PFL switch (the LED  
illuminates). The level meter indicates the corresponding signal (see [39]).  
When you adjust a signal with the GAIN control, it is advisable to select PFL  
mode, so that the level shown is independent of the channel fader position.  
IMPORTANT! High volume levels may damage your hearing and/or  
your headphones/loudspeakers. To avoid switch-on/off thumps from  
the console and any downstream devices, always make sure that the  
power amp(s) or active speaker(s) are the last components that are  
switched on and the first to be switched off. Always make sure that the  
appropriate volume is set.  
2.6.1 Talkback  
2.7 CD/Tape  
The talkback function of the EURODESK allows you to communicate with  
the musicians in the recording room or on the stage. The talkback signal  
is present at the AUX SEND outputs, which are particularly useful for  
monitor/ headphone mixes.  
[44]  
[48]  
[41]  
Fig. 2.20: CD/tape  
[47] TO MAIN controls the volume of, for example, a CD player connected to the  
CD/tape input connectors (see [49]).  
[42]  
[43]  
Fig. 2.17: Talkback section  
[48] When the STANDBY switch is pressed, all input channels are muted. Only the  
CD/tape signal will be routed to the main mix. In this way, you can prevent  
the microphones from pickung up unwanted sounds or noise that would  
interfere with CD playback during a break. The main mix and channel faders  
can remain in their normal positions while playing back music from CD  
(using the CD/TAPE INPUTs [49]), so you don’t lose your mix.  
[41] The LEVEL control determines the volume of the talkback signal at the  
AUX 1/2 outputs.  
[42] Use the TALK TO AUX 1/2 switch to activate the built-in talkback  
microphone. Its signal is sent to the AUX SEND jacks 1 and 2. Keep the  
switch pressed while you’re speaking.

[49] The CD/TAPE INPUT RCA connectors are for the connection of CD players,  
tape decks or other line-level sources. The signal volume is adjusted with  
the TO MAIN control.  
[44] The PHONES/CTRL R control adjusts the volume of the headphones  
connected to the PHONES/CTRL ROOM OUT jack (see [46]). If you have an  
active monitor speaker or power amp connected here, you can also control  
the monitor volume.  
[50] The CD/TAPE OUTPUT RCA connectors provide the stereo main mix signal to  
a tape deck or DAT recorder to record your mix. The signal is taken pre-fader,  
so that it will not be influenced by the fader positions.  
[45] These switches select the signal sent to the PHONES/CTRL ROOM jack.  
Available sources are: MAIN, CD/TAPE, AUX 1/2 and subgroups 1 - 2 and 3 - 4. 2.8 Master Aux Send 1 and 2

[56]  
“Digital effects processor”).  
[58] The FX LED level meters show the effects processor’s input signal.  
Be sure that the clip LED only illuminates with signal peaks. If it is lit  
all the time, the effects processor is overloading and hence producing  
unpleasant distortion.  
[59] The Effect displays show the currently selected presets.  
[60] This is the master FX 1 (or 2) SEND control for adjusting the volume of all  
FX send signals at the corresponding FX send jacks (see [66]) and at the  
inputs of the built-in effects processor. Use it to control the master signal of  
all FX 1/FX 2 signals from the input channels. When neither of the FX SEND  
controls is turned up, the effects processor will not receive a signal.

briefly to confirm your selection and activate the new effect.  
[62] The FX 1 (or 2) TO AUX 1 controls allow you to add the effect signal from  
the built-in effects processor (FX1 or FX2) to the AUX 1 monitor signal.  
Naturally, the effects processor must be provided with an input signal  
(i.e. the FX controls in the channel strips plus the FX SEND controls and the  
channel faders must be turned up).  
[54] Use the EQ IN switch to switch the equalizer on. In this case, the fader  
LEDs illuminate.  
[55] With the MAIN/AUX 1 switch you can determine the signal to be processed,  
either main or AUX 1.  
[63] This is the FX 1 (or 2) TO AUX 2 control adding the effect signal from the  
effects processor to the AUX 2 monitor signal. See [62]for further details.  
[56] Press the FBQ IN switch to activate the FBQ Feedback Detection System.  
The frequencies causing feedback are indicated by the brightly lit fader  
LEDs, while all other LEDs are darker. Simply lower the level of the brightly  
lit faders until feedback disappears.  
[64] The FX 1 (or 2) TO MAIN control routes the effect signal either to the main  
mix or the subgroups 1 and 2 (or 3 and 4), depending on the position of the  
selector switch (see [65]). When it is hard left, no effect signal will be audible.  
Here, too, the FX controls in the channel strips plus the FX SEND controls and  
the channel faders must be turned up.  
When the switch is in the “AUX 1” position (see [55]), the EQ fader  
LEDs show both the MAIN and the AUX 1 signal simultaneously.  
However, if feedback occurs in one of the signals, those signals without  
feedback will be faded out to enable clear identification of where  
feedback is occurring. If the MAIN signal happens to be the one carrying  
feedback, put the switch [55] to “MAIN” and then use the 9-band EQ to  
remove the feedback.

[65] These selector switches route the effect signal to the main mix or to the  
subgroups 1-2 or 3-4. If the MAIN/SUB switch is not pressed, the effect  
signal is sent to the main mix and the SUB 1/2 / SUB 3/4 switch below  
is inoperative. If the upper switch is pressed (SUB), however, the lower  
switch determines whether the effect signal is routed to subgroups 1 and 2  
(SUB 1/2) or 3 and 4 (SUB 3/4).  
[70] With the PHANTOM switch you can activate the phantom power supply  
for the XLR connectors of the mono channels for condenser microphones.  
The +48 V-LED [37]illuminates when phantom power is on. In most cases,

effects from our renowned studio effects processor  
VIRTUALIZER PRO DSP2024P. Use the FX control on the channels and the FX SEND  
control to supply the effects processor with signals. A built-in digital stereo  
effects processor has the benefit of no external wiring, thus reducing the risk of  
ground loops or level differences. Handling is therefore much easier.  
2.11 Rear panel  
PARALLEL FX  
The effects presets 1 to 70 provide classic “add-to-mix” effects. So, when you  
turn up the FX 1 (or 2) TO MAIN control, you create a mix of the (dry) channel  
signal and the effect signal. The balance between the two signals can be set  
with the FX send and FX 1/2 TO MAIN controls.  
This also applies to adding effect signals to the AUX 1 (or 2) monitor mix, with the  
exception that the mix here is adjusted with the AUX 1 (or 2) control in the  
channel strip and the FX TO AUX 1 (or 2) potentiometer. Of course, the effects  
processor must receive a signal from the channel using the FX 1 (or 2) control.  
Make sure that the PRE switch in the corresponding channel strip(s) is pressed.  
Otherwise, the AUX buses will be set post-fader making the volume of the  
AUX monitor signal dependent on the position of the channel fader(s).

[69] Use the POWER switch to put the mixer into operation. This switch should  
always be in the “Off” position when you connect your unit to the mains.  
Effects presets #71 and higher process the entire signal, unlike the “add-to-  
mix” effects. When you use an insert preset, be sure to separate the respective  
channel from all buses (SUB button and MAIN button not pressed) and only  
route the effect signal to the main mix (FX 1/2 control, FX SEND 1/2 control and  
FX TO MAIN 1/2 control).  
Please note: The POWER switch does not fully disconnect the unit from  
the mains. To disconnect the unit from the mains, pull out the main  
cord plug or appliance coupler. When installing the product, ensure the  
plug or appliance coupler is readily operable. Unplug the power cord  
when the unit is not used for prolonged periods of time.  
The channel fader of the corresponding channel remains active and  
governs (in combination with the FX controls) the signal level sent to  
the built-in effects processors.

4.1 Studio set-up  
The following wiring example shows a studio set-up for 4-track-recording:  
the drums are mixed down to two subgroups and then routed via the subgroup  
outputs to two tracks of the multi-track recorder. The remaining two subgroups  
are used to record the guitar, keyboard (stereo channel) and two vocal signals  
on the remaining two tracks. The four return paths from the recorder are  
connected to four separate mono input channels on the EURODESK. The built-in  
compressor is used only for the bass, which is why this input channel is separate  
from all buses (SUB and MAIN switch not pressed). The bass signal is directly  
routed from the built-in effects processor to the respective subgroups  
(FX TO MAIN control). The MAIN/SUB switch in the FX1 section is pressed,  
but NOT the SUB 1/2 SUB 3/4 button.

This example shows a classic live set-up. As in the studio example, four drum  
microphones, bass, keyboard (stereo channel), guitar and two vocal microphones  
are connected. The four drum channels (kick drum, snare, overhead L, overhead R)  
are mixed down to two subgroups and then routed to the main mix. This way,  
it is possible to conveniently control the volume of the entire drums in the main  
mix with the two subgroup faders. The built-in compressor insert effect is used  
for the bass. The corresponding input channel is separate from all buses and the  
bass signal is routed directly from the internal effects processor to the main mix  
bus. The MAIN/SUB switch must not be pressed in this case and the position of the  
SUB 1/2 SUB 3/4 switch is irrelevant.
