and lower band are 12 kHz and 80Hz 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 shouldnt turn this control
all the way to the left (-oo). Dont have the FX MUTE switch
pressed, and you should also not have the FX SEND fader pulled
down.
