Modifications
◊
These modifications require soldering. Attempt only if you are
experienced in using an iron on PCBs. Otherwise, refer to qualified
personnel. After modification the warranty becomes void.
◊
We wish to be absolutely clear that BEHRINGER cannot be held
responsible after you start disassembling your XENYX. If you make
much of your warranty privileges, think again.
◊
Links should not be threaded into the holes on the PCB, but are to
be soldered to the tinned areas around the holes. Bend the links a
little upwards.
6.1
Mon/Aux sends > post-EQ
Pre-fader switched monitor sends and aux sends are tapped off before the
equalizer. Do you prefer post-EQ? What are you waiting for? You don't have to
look far—the necessary information is found on the bottom side of the unit.
◊
Make sure to turn off the mixer and disconnect it from the mains before
removing the cover.
1)
Strip the PRE EQ lead.
2)
Solder a POST EQ link into place.
3)
Make these modifications to as many channels as required (does it have to be
all of them?).
6.2
Direct Out > pre-fader
If you prefer to use the Direct Out pre-fader than post-fader, the signal needs
to be tapped off before the fader and not after the fader. To perform this
modification, find the label “DIR-OUT” on the circuit board.
◊
Make sure to turn off the mixer and disconnect it from the mains before
removing the cover.
1)
Strip the POST FADER lead.
2)
Solder a PRE FADER link into place.
3)
Make these modifications to as many channels as required.
