Behringer Europack UB1204FX-Pro Owner's Manual

EURORACK UB1204FX-PRO/UB1204-PRO User Manual

Whereas it was useful to trace the signal flow from top to bottom in order to gain 

an understanding of the channel strips, we now look at the mixing console from 

left to right. The signals are, so to speak, collected from the same point on each of 

the channel strips and then routed to the main section all together.

Fig. 2.6: AUX SEND controls of the main section

A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on 

the corresponding channel.

AUX SEND 1 (MON)
The AUX SEND control MON acts as master control for aux send 1 and determines 

the level of the summed signal. In the UB1204FX-PRO, the MON control is called 

AUX SEND 1.

AUX SEND 2 (FX)
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.

SOLO
You can use the SOLO switch (UB1204FX-PRO only) to separately monitor the 

aux sends via the CONTROL ROOM/PHONES outputs and check these with the 

level meters.

Fig. 2.7: Aux send connectors

AUX SEND 1
If you use aux send 1 pre-fader, you would usually connect the AUX SEND 1 

connector to monitors via a power amp (or an active monitor system). If you use 

aux send 1 post-fader, proceed as described under aux send 2.

AUX SEND 2
The AUX SEND 2 connector outputs the signal you picked up from the individual 

channels using the FX control. You can connect this to the input of an effects 

device in order to  process the FX bus signal. Once an effects mix is created, 

the processed signal can then be routed from the effects device output back into 

the STEREO AUX RETURN connectors.

STEREO AUX RETURN 1
The STEREO AUX RETURN 1 connectors generally serve as the return path for the 

effects mix generated using the post-fader aux send. This is where you connect 

the output signal of the external effects device. If only the left connector is used, 

the AUX RETURN automatically operates in mono.

STEREO AUX RETURN 2
The STEREO AUX RETURN 2 connectors serve as the return path for the effects 

mix generated using the FX control. If these connectors already function as 

additional inputs, you can route the effects signal back into the console via a 

different channel, with the added benefit that the channel EQ can be used to 

adjust the frequency response of the effects return signal.

Fig. 2.9: Stereo aux return controls

STEREO AUX RETURN 1
STEREO AUX RETURN 1 is a stereo control which determines the level of the 

signal in the main mix. If STEREO AUX RETURN 1 is used as effects return, you can 

add the effects signal to any “dry” channel signal.
