Control Groups

Next, we'll place channels 1, 2, 3, and 4 into a gang fader control group. Press the Mode button for
GROUP2 repeatedly until it reads GANG. Then press the ON/OFF button for GROUP2 so that it
reads ON. Touch the buttons for Channels 1, 2, 3 and 4: the words "GP2" appear in each,
indicating that each of these channels have now been placed in Group 2, which has been designated as a
gang fader control group. (See Figure 9)

Move the Channel 1 fader; note that the faders for Channels 2, 3, and 4 also move, but with their relative
levels intact. Now try moving the faders for Channels 2, 3, and 4 in turn; note that any of these faders
can act as "master," affecting the level of all four channels. Note that the offsets within a gang fader
control group are logarithmic and not linear; this means that the distance between the faders decreases
relatively as they are lowered and increases relatively as they are raised, in order to reflect the logarithmic
nature of the fader path itself. At any time, you can easily change the relationship between the faders in a
gang fader control group; simply touch and hold one or more of them (be sure to make skin contact) and
rearrange them as desired, then let go. One potential problem with this procedure, however, is that if you
bring all faders fully up or fully down and then let go, the relationship between them will change — they
will all now be at equal level. To maintain the stored offsets, engage the MANUAL GROUP button in
the lower right-hand corner (so that it is lit green).
Note that when channels are assigned to a gang fader control group with MANUAL GROUP on (lit green),
their fader movements are no longer written as dynamic automation data (after all, that's why it's called a
"Manual" group!). Even if previous automation data has been written for those channels, if they are later placed
into a Manual gang control group, the fader automation data for those channels will no longer be played back
and the audio levels for those channels will be determined solely by the "live" fader position. For more
information, see the DMX-R100 Software Version 2.1/2.2 Supplement and Tutorial 3 in this guide.
