2.3.2 Monitor send and FX send connector

Fig. 2.7: Aux send connectors MON and FX
MON SEND
Connect the input of your monitor power amp or an active
monitor system here to make the monitor mix audible to the
musicians on the stage. The signal mix is created using the
channels MON controls.
FX SEND
The FX SEND connector outputs the signal you picked up
from the individual channels using the FX controls. You can
connect this to the input of an external effects device in order to
process the FX bus master signal. Once an effects mix is created,
the processed signal can then be routed from the effects device
outputs back into the AUX RETURN connectors.
+If the connected effects processor receives no
input signal, the FX MUTE switch is probably pressed
and/or the FX SEND control is too low. This also goes
for the built-in effects processor.
+Adjust your external effects processor to 100% wet
(effects signal only), because the effects signal is
added to the main mix along with the dry channel
signals.

2.3.3 Aux return connectors

AUX RETURN 1
The AUX RETURN 1 connectors generally serve as the return
path for the effects mix generated using the FX send. This is
where you connect the output signal of the external effects
device. If only the left connector is used, the aux return 1
automatically operates in mono.
+You can also use these connectors as additional
line inputs.
AUX RETURN 2
The AUX RETURN 2 connectors are used exactly the same
way as the AUX RETURN 1 connectors. If these connectors
