EURORACK UB1002FX/UB1202FX
BAL
The BAL(ANCE) control determines the levels of left and right
input signals relative to each other before both signals are then
routed to the main stereo mix bus. If a channel is operated in
mono via the left line input, this control has the same function as
the PAN control used in the mono channels.
LEVEL
The LEVEL control determines the volume of the channel being
sent to the main mix.
+4/-10
The stereo inputs of the EURORACK have an input sensitivity
switch which selects between +4 dBu and -10 dBV. At -10 dBV
(home-recording level), the input is more sensitive (requires less
level to drive it) than at +4 dBu (studio level).

FX SEND
The FX SEND connector outputs the signal you picked up
from the individual channels using the FX controls. You can
connect this to the input of an external effects device in order to
process the FX bus’ master signal. Once an effects mix is created,
the processed signal can then be routed from the effects device
outputs back into a stereo input.
+
If the connected effects processor receives no input
signal, the FX SEND control is probably too low. This
also goes for the built-in effects processor.
+
Adjust your external effects processor to 100% wet
(effects signal only), because the effects signal is
added to the main mix along with the “dry” channel
signals.
+
In this instance, the FX control of the channel being
used as an effects return should be turned fully
counterclockwise, otherwise feedback problems
can occur!
PHONES/CONTROL ROOM OUT
The stereo PHONES connector (at the top of the connector
panel) is where headphones are connected. The unbalanced
CONTROL ROOM OUT connectors carry the summed effects
and main mix signals as well as soloed channel signals. The
PHONES/CONTROL ROOM control in the main section adjusts
the level of both headphones and main monitor outputs.
MAIN OUT
The MAIN OUT connectors are unbalanced mono connectors.
The main mix signal appears here at a level of 0 dBu. The MAIN
MIX fader adjusts the volume of these outputs. Depending on
how you wish to use your mixer and which gear you own, you
can connect the following equipment:
Live PA systems:
A stereo dynamics processor (optional), stereo equalizer
(optional) and the stereo power amplifier for full-range
loudspeakers with passive crossovers.
In the UB1002FX/UB1202FX, 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).
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.
LEVEL
The LEVEL control determines the level of the channel signal
in the main mix.
+
Attention: Since the FX path for the effect processor
is connected post-fader, the LEVEL control has to
be turned up in order to get this channel’s signal to
the effects processor!
CLIP
The CLIP-LED’s of the mono channels illuminate when the
input signal is driven too high, which could cause distortion. If
this happens, use the TRIM control to reduce the preamp level
until the LED does not light anymore.
2.2 Stereo channels
Fig. 2.2: Connectors and controls on the stereo channels
LINE IN
Each stereo channel has two balanced line level inputs on 1/4"
connectors for left and right channels. If only the connector
marked “L” (left) is used, the channel operates in mono. The
stereo channels are designed to handle typical line level signals.
Both inputs will also accept unbalanced connectors.
FX
The FX send of the stereo channels functions similar to that of the
mono channels. However, since the FX send bus is mono, a mono
sum is first taken from the stereo input before it is sent to the FX bus.
