EURORACK UB2442FX-PRO/UB2222FX-PRO/UB1832FX-PRO/UB1622FX-PRO User Manual
LEVEL
For level matching, the stereo inputs on the UB1622FX-PRO, UB1832FX-PRO and
UB2222FX-PRO have a LEVEL switch to select between +4 dBu and -10 dBV.
At -10 dBV (homerecording level), the input is more sensitive than at +4 dBu
(studio level).
2.2.2 Equalizer stereo channels
The stereo channels contain a stereo EQ section. The cut-off frequencies of
the high and low bands are 12 kHz and 80 Hz respectively, while the center
frequencies of the high-mid and low-mid bands are 3 kHz and 500 Hz
respectively. The HIGH and LOW controls have the same characteristics as the EQ
in the mono channels. Both mid range bands are of the peak filter type. A stereo
EQ is superior to two mono EQs on a stereo signal as two separate EQs will usually
result in a discrepancy between left and right channels.
2.2.3 Aux sends stereo channels
In principle, the aux sends of the stereo channels function the same way as those
of the mono channels. As the aux sends are mono, the send from a stereo channel
is first summed to mono before it reaches the aux bus.
2.2.4 Routing switch, solo and channel fader
All Models

BAL
The BAL (ANCE) control has a similar function to the PAN control in the
mono channels.
The balance control determines the levels of the left and right input signals
relative to each other before both signals are routed to the left/right main mix
bus (or odd/even subgroup).
The remaining control elements in the stereo channels perform the same
functions as their counterparts in the mono channels (MUTE switch, MUTE and
CLIP LEDs, SOLO switch, SUB and MAIN switches and channel fader).

2.3 Interface panel and main section

Where 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 MON control, aux sends 1, 2 and 3 (FX)
Turning up the AUX 1 control in a channel routes the signal to the aux send bus 1.
◊ As the UB1832FX-PRO is equipped with an additional monitor path,
its first aux control in the channel strips is named MON. The console
also has a dedicated master fader (MON SEND) for this aux path.
AUX SEND 1, 2 and 4
The AUX SEND 1 control governs the master send level of the mix created by the
individual channel AUX 1 sends.
Likewise, the AUX SEND 2 contol is the master control for the aux 2 bus,
and AUX SEND 4 controls the AUX 4 bus.

AUX SEND 3 (FX)
The FX control determines the signal level for effects processing, i.e. regulates
the level to an external (or the internal) effects device.
UB1622FX-PRO and UB1832FX-PRO: On these consoles, this function is performed
by the AUX SEND 2 control (FX).
SOLO
You can use the SOLO switch to separately monitor the aux sends via the /
PHONES/CTRL ROOM 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 should be in
the SOLO position (not depressed).
2.3.2 Aux send jacks

AUX SEND jacks
The AUX SEND jack should be used when hooking up a monitor power amp or
active monitor speaker system. The relevant aux path should be set pre-fader.
◊
On the UB2222FX-PRO, aux send 1 is hard wired as pre-fader and hence
called MON. Model UB1832FX-PRO has a dedicated monitor output
(MON OUT jack), cf. chapter 2.3.4.
As already mentioned, the aux sends in the channels—if set post-fader—can be
used to connect to external effects devices.
