The EXPANDER PORT inputs have a nominal level of -2 dBu
(subgroup/mix) and +2 dBu (aux).
All variable gain circuits offer +15 dB (except aux re-

Modifications

These 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 warranty becomes discretionary.
+ Excuse us for repeating ourselves once again:
BEHRINGER is not responsible for anything what hap-
pens after you start disassembling your EURODESK
SX4882. Don't even think of it, if you make much of your
warranty privileges.
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.
23.1 Aux sends > post EQ
All channel aux sends are post mute and pre fader. If you want to
convert these to post EQ, carry out the following modification to
each channel. You will find a corresponding printing on the PCB
(see fig. 23.1).
1) Disconnect power supply.
2) Cut the "post mute" track.
3) Add in a "post EQ" link.
4) Repeat for all channels you want to be modified.

23.2 MIX-B source > post fader
That's it. You've decided to use the MIX-B as a stereo aux send
to FX rather than a separate stereo feed. You can move the tap
from the A-channel from pre to post the channel fader as follows.
Again, look for the printing on the PCB shown below.
1) Disconnect power supply.
2) Cut the "pre" track.
3) Add in a "post" link.
4) Repeat for all channels you want to be modified.

23.3 LED meters > pre fader
In channel mode the meterbridge monitors the DIRECT OUT
signal (post EQ, post mute and post fader). You would prefer to
see what's going on pre mute and pre fader? Once you found the
corresponding printing on the PCB, all you have do is:
1) Disconnect power supply.
2) Cut the "line out" track.
3) Add in a "pre fade" link.
4) Repeat for all channels you want to be modified.
