Mute Groups
There are many times when it is useful to mute some of the inputs and outputs. For example, you might want to mute everything but a stereo input
for break music. Or there may be a part of your show when the band leaves the stage while one member does a solo number. Mute groups let you
mute multiple inputs and outputs from a single button. For more information on mutes, see "Mutes" on page 19

DCA Groups
A DCA groups faders together so the overall level of all the channels in the group can be controlled by a single DCA fader.
A DCA fader does not change the position of any of the faders in the group.
IMPORTANT: Here is an important thing to know – if the DCA master fader is at 0.0 (the unity (U) mark), it does nothing to the
level of an assigned channel. The DCA adds or subtracts level. Move the DCA Fader up 3 dB and everything it’s assigned to will
increase by 3 dB. Move it down 3 dB and – well you probably figured that out. Remember that assigning or unassigning a channel
to a DCA Group can cause a sudden change in the level of the channel so it’s good practice to have the DCA master at 0.0 when
changingassignments.
To Setup a DCA Group:

Continue selecting channels as you
wish.
You can assign inputs, outputs and FX Master faders to a DCA. If you assign an input, and the output to which it's going to the same DCA, changes
you make using the DCA are doubled for the input. Raise the DCA 3 dB, the input is effectively raised 6 dB.

When you mute a DCA, all channels assigned to that DCA are muted. If a channel is muted by the channel Mute button, or a Mute Group, the DCA
does not un-mute the channel when the DCA is un-muted.
