5. AUX Channels Modification

All monitor and effects signals are tapped into post mute and pre fader,
which resembles the function of a pre fader aux channel on conventional mixing
consoles. If you prefer to use the aux channels mainly for effect applications,
we suggest to alter them to post Fader. The difference is that you extract
the respective channels' signal from the effect mix, too, when you turn the
LEVEL-control to minimum. You can do this modification for each channel
individually, the choice is yours.

The following modifications put your soldering skills to the test.
Only attempt to implement them if you feel you have enough
past experience. Consider hiring professional help. Regardless of
who implements these modifications, they effectively void all
warranty claims.
◊
A piece of advice for the brave: bridge endings that are to be soldered
should not be put into the drill holes. Instead, bridge endings should
be soldered above the drill holes in a flat fashion! A bridge should be
somewhat upwardly curved between both of the bases.
1. Power down the unit and unplug the power cord before you remove the
cover from the rest of the housing!
2. The positions in question are found on the part of the circuit board located
perpendicular to the front side. Please observe figure 5.1.
◊
Hold the unit so that you can read the FX/MON insignia on the circuit
board. Soldering points should match those in the illustration.
3. Separate the "pre fader" conductor path.
4. Solder a "post fader" bridge.
5. Repeat this step on as many channels as desired.
