and lower band are 12 kHz and 80 Hz respectively. The mid
band is configured as a peak filter with a center frequency of
2.5 kHz. Unlike shelving filters, the peak filter processes a
frequency range that extends upwards and downwards around
its middle frequency.
2.1.3 Aux sends (MON and FX)
Fig. 2.3: The AUX SEND controls in the channel strips
Aux sends take signals via a control from one or more channels
and sum these signals to a so-called bus. This bus signal is sent
to an aux send connector and then routed, for example, to an
active monitor speaker or an external effects device. The return
from an external effects device can then be brought back into
the console via the aux return connectors.
For situations that require effects processing, the aux sends
are usually switched post-fader so that the effects volume in a
channel corresponds to the position of the channel fader. If this
were not the case, the effects signal of the channel would
remain audible even when the fader is turned to zero.
When setting up a monitor mix, the aux sends are generally
switched to pre-fader; i.e. they operate independently of the
position of the channel fader.
Both aux sends are mono, are sourced after the equalizer and
offer up to +15 dB gain.

If you press the MUTE switch of the respective
channel, aux sends and returns (MON and FX) are
not being muted.
MON
In the UB1222FX-PRO, aux send 1 (MON) is wired pre-fader
and is thus particularly suitable for setting up monitor mixes.
FX
The aux send labeled FX is for feeding external effects devices
and is thus set up to be post-fader.
In the UB1222FX-PRO, the FX send is routed directly to the
built-in effects processor. To make sure that the effects
processor receives an input signal, you shouldn’t turn this control
all the way to the left (-oo). Don’t have the FX MUTE switch
pressed, and you should also not have the FX SEND fader pulled
down.
2.1.4 Pan, mute switch and channel fader
Fig. 2.4: Channel fader and additional control elements
PAN
The PAN control determines the position of the channel signal
within the stereo image. This control features a constant-power
characteristic, which means the signal is always maintained at a
constant level, irrespective of position in the stereo panorama.
MUTE
Use the MUTE switch to mute the channel. This means that the
channel signal is no longer present in the main mix. However, the
aux sends (MON and FX) remain active.
If you want to use insert effects, you have to press the MUTE
switch, thus removing the signal of the corresponding channel
from the main mix (see also ch. 3: “DIGITAL EFFECTS PROCESSOR
AND XPQ SURROUND FUNCTION”). The processed signal is
then routed via the FX TO MAIN control back to the main mix.
MUTE LED
The MUTE LED indicates that the relevant channel is muted.
CLIP LED
The CLIP LED lights up when the input signal is driven too high.
In this case, lower apparent frequency increase on the channel
EQ to avoid distortion. For example, lower the mids and the highs
somewhat to emphasize the bass. If you don’t wish to change
the EQ settings under any circumstances, try lowering the TRIM
control somewhat (counterclockwise).
If you inserted an external effects processor via the insert
connector (e. g. a dynamic processor), then you should also
control its output signal level. It should not be higher than its input
signal level (0 dB).
The channel fader determines the level of the channel signal in
the main mix.
+
Attention: Since the aux path for the effect processor
is connected post-fader, the channel fader has to
be turned up in order to get this channel’s signal to
the effects processor!
