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.

{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 cor-
responding 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.
(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 depen-
dent on the fader position, so you can create completely
independent monitor mixes.
For most applications when controlling an external ef-
+
fects 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).
(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 actu-
ally 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.

(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 TRIM
control. This LED also illuminates when you activate the solo
function with the SOLO switch below.
(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 sub-
groups. 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).
(17) The MAIN switch routes the signal to the main mix.
(18) The channel fader governs the level of the channel signal
as part of the main mix (or submix).
(19) Each stereo channel is equipped with two balanced line-level
inputs on 1/4" TRS connectors for the left and right channels.
The channels can also process mono signal, as long as you
use the "LEFT" jack only.
