EURORACK MX2004A
8.3 Modifications
The following modifications require you to do some soldering. Attempt only if you are experienced in using an iron on
PCBs. Otherwise, refer to qualified personnel. After modification the BEHRINGER warranty becomes discretionary.
Links should not be threaded into holes on the PCB. They should be soldered to the tinned areas around the
holes, and bowed slightly upwards in between.
Mono channel aux send 2 > pre-fader
Mono channel aux sends 2 are post-fader. If you want to convert them, carry out the modification described
below to each mono channel you want to be altered. The right PCB area is indicated by a yellow printing (see
figures below).
1) Switch desk off and disconnect it from the mains supply!
2) Cut the “post” track.
3) Add in a “pre” link.
Repeat for all mono channels you want to be modified.

8.4 Expanding
When the EURORACK is your main mixer, you may find that you run out of inputs as your system expands.
It is possible to expand your mixing system by combining two or more mixers.
Adding extra Line inputs to your EURORACK:
A small line mixer (such as the BEHRINGER ULTRALINK PRO MX882) can inexpensively add extra line inputs
to your console. With the ULTRALINK PRO, any stereo, line-level input on your EURORACK can become a
stereo line input plus a further 6 panable mono line inputs. Great for adding tape monitor returns etc.
Linking two EURORACK:
Simply take the main mix output of one, and feed it into a suitable stereo line input of the second.
Linking the EURORACK to a master console:
Feed any or all of the main mix, Alt 3-4 and aux outputs from your EURORACK into separate channels of the
master console. The aux outputs should be routed only to individual aux send buses on the master console.
Now the aux sends from the EURORACK can access effects currently used by the master console.
The EURORACK outputs are essentially submixes of several channels of sound, and are therefore likely to be
considerably higher than the typical source signals (coming from mics, MIDI instruments or tape) seen by the
remaining channels of the master console or the 2nd EURORACK.
A usefull feature here is the 20 dB pad buttons on the back panel. These buttons enable you to feed the
balanced output of the MX2004A to the microphone input of another console. This way it is possible to make
for instance a separate keyboard or drum kit mix and feed that to the front of house console (without having to
use XLR to jack adapters to feed the Line inputs which may also be unbalanced).
