VCA GROUPING
When the level of the VCA master is
adjusted it will change the audio level
of all its slaves by the same amount.
Changing the CUT, AFL and PFL
settings of a VCA master applies the
same settings to its slaves.
The slave faders will not move when
their master is adjusted, but the Null
LEDs will illuminate to indicate whether
the audio is above or below the position
of the fader.
The MR and SL LEDs next to the Assign
buttons on the fader strip indicate
whether that fader is a master or a slave.
The editing of VCA groups is enabled
and disabled using the States screen.
This provides protection against
accidental changes.
Primary and Secondary VCA Masters
It is possible to select a VCA master as
a slave of another VCA group. When this
happens, 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.
The number of slaves in VCA group with
a primary master would include all the
primary master’s slaves and the slaves of
all its secondary masters. A secondary
master fader has both the MR and SL LED
lit.
It is possible to create the primary or
secondary group in any order. A slave can
be made into a secondary master by
adding slaves to it. If a slave added to
the VCA group is already a master it will
become a secondary master.
5.1 Surround Channels
If a surround master is part of a VCA
group then the VCA primary and
secondary master levels, cut settings
and APFL settings affect all of its spill
legs. It is not possible for the spill faders
themselves to be masters or slaves of a
VCA group.
VCA Group Interrogation
Interrogation provides a clear way of
indicating VCA group assignments.
When the fader assign button of a VCA
group member is held down, the fader
assign buttons of all members of the
same group will be lit, and the fader
assign buttons of paths which are not
part of the group will cease to be lit.
Interrogation of a Primary Master will
light the fader assign buttons of its
primary slaves and secondary masters.
Interrogation of a secondary master will
light the Assign buttons of its secondary
slaves, and the primary master’s Assign
button will flash.
