8EURORACK UB1204FX-PRO/UB1204-PRO User Manual

2.3Connector panel and main section

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.

2.3.1 Aux sends 1 and 2

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.

◊If you want to monitor the signal of just one AUX bus, none of the other SOLO SWITCHES should be pressed and the MODE switch must be in the SOLO position (not pressed down).

2.3.2 Aux send connectors 1 and 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.

2.3.3 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.

◊You can also use these connectors as additional line inputs.

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.

◊In this instance, the FX control of the channel being used as an effects return should be turned fully counterclockwise, otherwise feedback problems could occur!

◊If you wish to use the internal effects processor, no connectors should be plugged into STEREO AUX RETURN 2.

2.3.4 Stereo aux return

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.

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.

◊In this instance, the effects device should be set at 100% effect.
