2.3 Connector 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
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.
2.3.3 Stereo aux return connectors
Fig. 2.8: 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
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.
