2.2.2 Stereo channel equalizer
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 ( 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.
2.2.3 Stereo channel aux/FX send buses
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. 2.7: Channel fader, balance control, mute switch, etc.
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 (SL2442FX-PRO)
or 29 - 32 (SL3242FX-PRO)
Fig. 2.8: Auxiliary stereo channels
Your EURODESK has two stereo channels with an aux send
section ( AUX 1 and AUX 2) and one LEVEL control . 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 1/4"
TRS connectors for the left and right channels, and a SOLO
switch.
Similar to the CD/TAPE inputs (see ) the auxiliary stereo
channels can be connected to CD players, tape decks, etc., for
example, to feed in playback material.
2.4 Subgroups 1 - 4
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.
The subgroup faders determine the volume of the subgroup
signal at the subgroup output . Depending on the
position of the routing switch you can thus control the
subgroup volume in the main mix.
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 the
SOLO/PFL switch ). The SOLO LED illuminates when
the SOLO switch is pressed.
