Well, part of the confusion is an indiscriminate interchanging of the terms aux where in some places he means group. To
clear it up, let's eliminate those terms altogether.
There are master dials on the output that are permanently linked to 1/4"
TRS (there's no such thing as 1/4" TLR;
TRS stands for Tip, Ring, Sleeve). There are also master faders that are permanently linked to
XLR outputs.
He asked if there's any way to make the faders control what comes out of the
TRS outputs. The answer is no.
You can
switch what bus feeds the dials vs the faders with those little blue switches. Normally, the aux busses, which are controlled by the dials on each
channel strip, feed the dials/
TRS outputs, and the group busses, which are controlled by the group assign switches and the
channel level fader for each
channel, feed the faders/
XLR outputs.
Pressing the blue
button for each pair of groups/auxes will
switch these so that the aux busses feed the faders and
XLR outputs, and the group busses feed the dials.
The faders, however, are permanently linked to the
XLR outputs, and the dials are permanently linked to the
TRS outputs.
If you're any good at making sense out of
block diagrams, download the diagram for the 2200 from A&H's website. Near the center is a vertical dotted
line with a black square in the middle of it, labeled "GROUP/AUX REVERSE". If you follow that dotted
line, you'll see it
pass through a pair of DPST switches (just look at the top half of the diagram, the
mono channel, to keep things simple).
It's
clear on the diagram that these switches come
before the output faders/dials, not after, so the switches don't affect the routing of those output controls to output jacks; those are hard-wired.
1/4" should be group outs, if the GL2200 has them, if not, then the grp/aux
switch should change the outputs to the group outs....
No, this is incorrect. By default as shipped from the factory (ie, in typical
FOH configuration), the
TRS jacks are aux outs, and the
XLR jacks are group outs. The group/aux reverse
switch reverses these, BUT it reverses the controls feeding these outputs, too; the faders always stay with the XLRs, the pots with the TRSs. The only thing you can change is what feeds those pots/faders.
