EURODESK SX3282 User Manual

12. Expanding

When the SX3282 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 Eurodesk
A small line mixer can inexpensively add extra line inputs to your console.
With the ULTRALINK PRO, any stereo, line-level input on your SX3282 can become
a stereo line input plus a further 6 pan-able mono line inputs. Great for adding
tape monitor returns etc.
Linking the SX3282 to a master console
Feed any or all of the main mix, subgroup outputs and aux outputs from your
SX3282 into separate input 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 SX3282 can access effects currently used by the
master console.
The SX3282 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 master console.
Therefore, we recommend a reduction of gain in those channels of the master
console that are fed by the SX3282's outputs.

13. Modifications

The following modifications require you to do some soldering. Only attempt
that if you are experienced in using an iron on PCBs. Otherwise, refer to qualified
personnel. After modification the Behringer warranty becomes void.
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.
Aux sends > pre EQ
All channel aux sends are post-EQ. If you want to convert them, carry out the
modification described below to each channel. The right PCB area is indicated by
a yellow printing (see figures below).
1) Disconnect power supply.
2) Cut the 'post' track.
3) Add in a 'pre' link.
4) Repeat for all channels you want to be modified.
