EURORACK
UB1002FX/UB1202FX
If you wish to use multi-way loudspeaker systems without an
integrated crossover, you have to use an active crossover and
several power amplifiers. Often, limiters are already built into
active crossovers (e.g. BEHRINGER SUPER-X PRO CX2310 and
ULTRADRIVE PRO DCX2496). Active crossovers are implemented
directly before the power amplifier, and they divide the frequency
range into several segments that are first amplified in the amplifiers
and then passed on to the corresponding loudspeakers.
Recording:
For mastering, using a stereo compressor such as the
COMPOSER PRO-XL MDX2600 can be recommended. Use it to
custom-tailor the dynamic characteristics of your signal to the
dynamic range of the recording equipment you are using. The signal
is in this case passed on from the compressor into the recorder.
CD/TAPE INPUT
The CD/TAPE INPUTs are used to bring an external signal
source (e.g. CD player, tape deck, etc.) into the console. They
can also be used as a standard stereo line input, so the output of
a second EURORACK or BEHRINGER ULTRALINK PRO MX882
can be connected. Alternatively the line or tape output of a hi-fi
amplifier with source selection switch could also be hooked up
here, allowing you to easily listen to additional sources
(e.g. cassette recorder, minidiskplayer, sound card etc.).
TAPE OUTPUT
These connections are laid out as RCA connectors and are
wired parallel to MAIN OUT. Connect the inputs of a computer
sound card or a recorder here. The output signal level is set up
using the highly accurate MAIN MIX fader.

+48 V
The red +48 V LED lights up when the phantom power is
turned on. Phantom power is required to operate condenser
microphones and is activated using the +48 V switch located
above the +48 V LED.
+ Connect microphones before you switch on the
phantom power supply. Please do not connect
microphones to the mixer (or the stagebox/
wallbox) while the phantom power supply is
switched on. In addition, the monitor/PA loud-
speakers should be muted before you activate
the phantom power supply. After switching on,

wait approx. one minute to allow for system
stabilization.
+ Caution! You must never use unbalanced XLR
connectors (PIN 1 and 3 connected) on the MIC
input connectors if you want to use the phantom
power supply.
POWER
The blue POWER LED indicates that the console is powered on.
LEVEL INDICATOR
The 4-segment display accurately displays the relevant signal
level.
LEVEL SETTING:
To correctly set the gains of the channels, first set the LEVEL
controls of the input channels to their center positions. Then use
the TRIM controls to increase the input amplification until signal
peaks show 0 dB on the level meter.
When recording to digital recorders, the recorders peak meter
should not go into overload. While analog recorders can be
overloaded to some extent, creating only a certain amount of
distortion, digital recorders distort quickly when overloaded. In
addition, digital distortion is not only undesirable, but also renders
your recording completely useless.
When recording to an analog device, the VU meters of the
recording machine should reach approx. +3 dB with low-
frequency signals (e.g. kick drum). Due to their inertia VU meters
tend to display too low a signal level at frequencies above 1 kHz.
This is why, for example, a Hi-Hat should only be driven as far
as -10dB. Snaredrums should be driven to approx. 0 dB.
+ The CLIP-LEDs of your EURORACK display the level
virtually independent of frequency. A recording level
of 0 dB is recommended for all signal types.
MAIN MIX
Use the MAINMIX fader to adjust the volume of the main out.
PHONES/CONTROL ROOM
Use the PHONES/CONTROL ROOM control to adjust the
signal level of the CONTROL ROOM and PHONES outputs.
CD/TAPE TO MIX
When the CD/TAPE TO MIX switch is pressed, the CD/tape
input is assigned to the main mix providing an additional input for
tape machines, MIDI instruments or other signal sources that do
not require any processing.
CD/TAPE TO CTRL
Press the CD/TAPE TO CTRL switch if you want to monitor
the CD/tape input via the CTRL ROOM and PHONES outputs.
A typical studio application of this function is recording music
into a digital audio workstation (DAW) with simultaneous
reproduction (see ch. 3.1).
+ If you are recording a signal via the TAPE OUTPUT
and wish to listen to this simultaneously via the
CD/TAPE INPUT, do not use the CD/TAPE TO MIX
switch. Doing this would create a feedback loop,
since the signal would be routed, via the main mix,
back to tape via the TAPE OUTPUT. To monitor the
CD/TAPE INPUT, use the CD/TAPE TO CTRL switch
to assign the tape signal to the monitor(s) or
headphones. This will avoid the tape signal being
routed to the TAPE OUTPUT.
FX TO CONTROL
If you want to monitor only the effects signal in your
headphones or monitor speaker(s), press the FX TO CTRL
switch. Now the signal of the effects processor can be monitored
alone, and the main mix and/or CD/tape signal is no longer present
on the phone and control room outputs.
