1. Introduction
FBQ Feedback Detection System
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.
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:
• 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
• 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
• 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
“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.
What is more, the EURODESK comes with two effects processors
using 24-bit A/D and D/A converters and the effects algorithms of
our renowned 19" multi-effects device VIRTUALIZER PRO
DSP2024P. Each processor offers 99 presets with first-class room
simulations, delay and modulation effects as well as compressor, tube distortion
and numerous other effects available—all with excellent audio quality!
The mixer is equipped with a state-of-the-art integrated
switch-mode power supply. Unlike conventional designs,
this supply automatically adapts to supply voltages between
100 and 240 V. With its considerably higher efficiency, it is also
more economical in terms of power consumption than standard power supply units.

EURODESK SX3242FX/SX2442FX User Manual
2. Control Elements and
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
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 finetuning can be done with a music signal and the LEVEL SET LED, which will
illuminate when the optimum operating level has been set.
(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
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.
Fig. 2.1: Connectors and controls of the mic/line inputs
(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).
◊ 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”.
(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).
(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.
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).
(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.
Fig. 2.2: Equalizer section of input channels
(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).
(7) The MID control allows you to raise or lower the mid-range level. It is a semiparametric 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.
(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).
2.1.3 Aux/FX send buses
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.
Fig. 2.3: AUX/FX send controls in the channel strips
EURODESK SX3242FX/SX2442FX 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) ).
(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.
(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).
◊ 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).
(11) FX 1 and FX 2 controls provide a direct route to the built-in effects processor.
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.
(18) The channel fader governs the level of the channel signal as part of the main
mix (or submix).
2.2 Stereo channels
2.2.1 Channel inputs
◊ Please also read chapter 2.10 “Effects section” and
3 “Digital effects processor”.
2.1.4 Mono channel fader and further control elements
Fig. 2.5: Stereo channel inputs
(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.
(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.
2.2.2 Stereo channel equalizer
Fig. 2.4: Channel fader, pan control, mute button, etc.
(12) The PAN control determines the position of the channel signal in the
stereo mix as well as the subgroup to which the channel signal is routed
(see chapter 2.4).
(13) Use the MUTE switch to mute the channel signal, so it is no longer part of
the main mix. At the same time, all aux buses set to post-fader are muted for
the respective channel, while the pre-fader monitor buses remain operative.
The MUTE LED is illuminated when the channel is muted.
(14) The CLIP LED illuminates when the channel overloads. In this case,
please reduce the input gain using the GAIN control. This LED also illuminates
when you activate the solo function with the SOLO switch below.
Fig. 2.6: Stereo channel equalizer
The stereo channels are equipped with a stereo equalizer. The filter types
and cutoff frequencies for HIGH and LOW filters are the same as on the mono
channels. Instead of one semi-paramtric midrange band, the stereo channels
have two separate midrange bands (21) (HIGH MID and LOW MID) with fixed
mid-frequencies (3 kHz and 400 Hz). Stereo EQs are preferable for processing
the frequency response of stereo signals. With two mono equalizers you might
encounter problems with different settings between the left and right channels.
EURODESK SX3242FX/SX2442FX 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.
2.2.4 Stereo channel fader and other control elements
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.
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).
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)
(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.
(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.
Fig. 2.10: Subgroup outputs 1 - 4
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.
(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”).
EURODESK SX3242FX/SX2442FX User Manual
2.5 Mono out section for
subwoofer applications
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.
(33) Use this high-precision MAIN fader to control the output level of the main mix.
Fig. 2.14: XLR main out connectors
(34) The MAIN OUT(puts) are balanced XLR connectors with a nominal operating
level of +4 dBu and provide the main mix signal.
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
(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.
(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) ).
(31) Use the LOW PASS FILTER switch to activate the filter function (LED illuminates).
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
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.
Fig. 2.13: Main out fader
(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.
EURODESK SX3242FX/SX2442FX 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.
2.6.1 Talkback
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.
◊ 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.
2.7 CD/Tape
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) ).
Fig. 2.17: Talkback section
(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.
(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.
(49) (50)
(43) This is the built-in talkback microphone.
2.6.2 Phones & control room
Fig. 2.21: CD/tape connectors
Fig. 2.18: Phones/control room section
(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.
(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.
(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.
(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.
2.8 Master Aux Send 1 and 2
Fig. 2.19: Phones/control room output
(46) Connect your headphones or monitor speaker to the PHONES/CTRL
ROOM OUT ¼" TRS connector.
Fig. 2.22: Master aux sends
EURODESK SX3242FX/SX2442FX User Manual
(51) These are the master AUX SEND controls 1 and 2 for adjusting the volume
level sent to the corresponding aux send connectors (see (52) ). This way,
you can control the mix of all AUX 1 or AUX 2 signals of the input channels.
The AUX SEND section also has a SOLO switch.
2.10 Effects section
Fig. 2.23: Master aux send outputs
(52) Use the AUX SEND outputs 1 and 2 to take the master AUX SEND
signals and route them to an external effects device or your monitor
speakers. Subsequently, you can return the effect signal, e.g. via the
STEREO FX RETURN inputs (see (67) ) or specific input channels.
2.9 Graphic 9-band stereo equalizer
Fig. 2.25: The digital effects processor
(57) Here you will find a list of all multi-effects presets (see also chapter 3
“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.
(55) (54)
Fig. 2.24: The graphic stereo equalizer
(53) Your EURODESK is equipped with a graphic 9-band stereo equalizer
processing either the main or the AUX 1 signal. Use the EQ to adapt the
sound to the room acoustics.
(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.
(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.
◊ 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.
(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.
(61) Turn the FX 1 (or FX 2) control to select an effects preset. Then, push it
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).
(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.
(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.
EURODESK SX3242FX/SX2442FX User Manual
(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,
dynamic microphones can still be used as long as they are connected in
a balanced configuration. If in doubt, please contact the manufacturer of
your microphone!
(71) The mains connection is a standard IEC receptacle. An appropriate power
cord is supplied with the unit.
(72) FUSE HOLDER. Before connecting the unit to the mains, ensure that
the voltage setting matches your local voltage. Blown fuses should only
be replaced by fuses of the same type and rating. Please also read the
information given in chapter 6 “Specifications”.
Fig. 2.26: FX send and return connectors
(66) The FX SEND 1 and 2 connectors also provide the master FX send signals,
for example, to connect them to the inputs of an external effects device.
However, these are “dry” signals only with no “effect signals” from the
built-in effects processor!
3. Digital Effects Processor
(67) The Stereo FX RETURN inputs 1 and 2 return the effect signals from external
effects processors and add them to the main mix.
Fig. 3.1: List of all effects presets
Fig. 2.27: Footswitch connectors
(68) The FOOTSW(ITCH) connector allows you to connect a standard dual
footswitch to separately enable/disable FX 1 or FX 2. The tip of the ¼" plug
controls FX 1, the ring controls FX 2.
2.11 Rear panel
Here is the list of all multi-effects presets. The built-in
effects processor offers you various standard effects such as
reverb, chorus, flanger, delay and a variety of combination
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.
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.
Fig. 2.28: The rear panel of the EURODESK
(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.
◊ 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.
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).
INSERT FX (channel is muted)
Effects presets #71 and higher process the entire signal, unlike the “add-tomix” 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).
◊ 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. Wiring Examples
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.
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

◊ Please make sure that none of the subgroup routing switches
(1-2 and 3-4) is pressed in the channels connected to the recorder
returns. Otherwise, a feedback loop will be created as soon as you
start recording. Only press the MAIN switch on these input channels,
so that the tape return signals are routed to the main outs and
Phones/CTRL room outputs of the console.

Fig. 4.2: Wiring the console for live operation
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.
5. Audio Connectors
The inputs and outputs of the BEHRINGER EURODESK are designed as unbalanced
¼" TS connectors—except for the balanced line inputs of the mono and stereo
channels and the main out connectors. Of course, all inputs and outputs work
with both balanced and unbalanced connectors. The tape ins and outs are stereo
RCA connectors.
◊ Please ensure that only qualified personnel install and operate the
EURODESK. During installation and operation, the user must have
sufficient electrical contact to earth. Electrostatic charges might
affect the operation of the unit.
