Introduction1.
FBQ Feedback Detection System
One of the most outstanding features of this console is the
FBQ Feedback Detec tion System, which is part of the graphic
equalizer. This ingenious circuit makes it possible to detect and
subsequently eliminate feedback frequencies ver y 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 nest 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 eects processors
using 24-bit A/D and D/A converters and the eects algorithms of
our renowned 19" multi-eects device VIRTUALIZER PRO
DSP2024P. Each processor oers 99 presets with rst-class room
simulations, delay and modulation eects as well as compressor, tube distortion
and numerous other eects 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 eciency, it is also
more economical in terms of power consumption than standard power supply units.

Control Elements and 2.
Connections
This chapter describes the various control elements of your mixing console.
All controls and connections are explained in full detail.
Mono input channels2.1
Microphone and line inputs2 .1.1
Fig. 2.1: Connectors and controls of the mic/line inputs
Each mono input channel is equipped with a balanced microphone input [1]
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”.
Each mono input also has a balanced line input on ¼" TRS connectors. [2]
Of course, these inputs can also be used with unbalanced plugs
(¼" TS connector).
The [3] 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 eects, 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
ow interruption. For this you need a cable with a ¼" TS connector on the
recorder/eects processor end, and a bridged stereo ¼" TRS connector on
the console end (tip and ring interconnected).
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 netuning can be done with a music signal and the LEVEL SET LED, which will
illuminate when the optimum operating level has been set.
Mono channels are equipped with a high-slope [5] LOW CUT lter eliminating
unwanted low-frequency signals, such as oor rumble (18 dB/oct., -3 dB
at 80 Hz).
Equalizer2.1.2
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. 2.2: Equalizer section of input channels
The [6] HIGH control in the EQ sec tion controls the high frequency range of
the respective channel. It is a shelving-type lter which can boost or cut all
frequencies above a xed frequency (12 kHz).
The [7] MID control allows you to raise or lower the mid-range level. It is a semi-
parametric peak lter, 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.
The [8] LOW control boosts or cuts the low-frequency range. Like the HIGH lter
it is a shelving-type lter, which raises or lowers the level of all frequencies
below a specic frequency (80 Hz).
Aux/FX send buses2.1.3
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 eects
device, for example. The FX returns are subsequently used as a return bus for the
processed signal.
The [4] 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 rst scale has a gain from +1 0 to +60 dB for
the MIC input.

[20]
[21]
On each channel, the [9] 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.
Press the [10] 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 ◊
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).
FX 1[11] and FX 2 controls provide a direct route to the built-in eec ts processor.
Additionally, they can be used to control an external eects unit, via the
FX SEND 1 and 2 outputs (similar to the AUX SEND 1 and 2 jacks). To ensure
that the internal eects 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.
Please also read chapter 2.10 “Effects section” and ◊
3 “Digital effects processor”.
The [15] 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 aecting 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] ).
The [16] 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).
The [17] MAIN switch routes the signal to the main mix.
The channel fader governs the level of the channel signal as part of the main [18]
mix (or submix).
Stereo channels2.2
Channel inputs2.2.1
Mono channel fader and further control elements2.1.4
Fig. 2.4: Channel f ader, pan control, mute b utton, etc.
The [12] 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).
Use the [13] 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.
The [14] 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. 2.5: Stereo c hannel inputs
Each stereo channel is equipped with two balanced line-level inputs on [19]
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.
All stereo channel strips have a [20] 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.
Stereo channel equalizer2.2.2
Fig. 2.6: Stere o channel equalizer
The stereo channels are equipped with a stereo equalizer. The lter types
and cuto frequencies for HIGH and LOW lters 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 xed
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 dierent settings between the left and right channels.
