VCA GROUPS
Artemis’ moving fader VCA groups
provide control over fader level, cut
status and APFL status.
CreatinganddissolvingVCAgroups
To set up a VCA group, first choose a
fader to be master and then assign a
number of other faders for it to control
as slaves. To do this push and hold the
master fader’s assign button, then press
the assign buttons of any paths which
are to become slaves, or press again to
remove. Slaves can only have one master.
Grouphierarchy
Artemis provides up to three levels of
group hierarchy. A master can have slaves
but can also be made a slave of another
master. Fig 1 illustrates the hierarchy.
When the full hierarchy is in place, the
slave master is known as the secondary
master, and its master is known as the
primary master.
When the level of a primary master is
adjusted it will change the audio level
of its own slaves and the level of its
secondary master’s slaves by the same
amount. Changing the CUT, AFL and PFL
settings of a primary master applies the
settings to the slaves, secondary masters
and their slaves.
When the level of a secondary master
is adjusted, the audio level of all its
slaves changes by the same amount.
Its adjustment will not affect the level of
the primary master or its slaves. Changing
the CUT, AFL or PFL of a secondary
master applies the settings to the
secondary master’s slaves only.
Faderstatusindicators
Each fader contains two indicators next to
each assign button as shown in Fig 2.
• Neither indicator will be illuminated if
the fader is not part of any VCA group.
• The MR indicator illuminates red if the
fader is a master
• The SL indicator illuminates green if
the fader is a slave
• Both MR and SL indicators illuminate if
the fader is a secondary master.

If a fader contains a path and that
same fader is made into a group
master, the path below becomes a
slave of the master. Such paths are
shown as dashed in this diagram. A
fader which does not contain a path
can also be made a group master.
