9.2: VCA GROUPS
MUTE & VCA GROUPS > VCA GROUP OPERATION
VCA Groups conguration is started by pressing the MUTE & VCA GROUPS [SETUP] button. When you press a VCA
Master [SOLO/SEL] button you can assign channels to that VCA group with their individual [SOLO/SEL] buttons, and
also access VCA group options - including labelling - in the Master Bay Vistonics. See below for more information.
You can select EITHER output channels OR input channels to be part of a normal VCA group.
In order to assign VCAs, the VCA masters [SOLO/SEL] buttons have to be made available by selecting the appropri-
ate Master Bay Fader Pages layer - [VCA] for VCA masters 1-8, or [E] for VCA masters 9-16.
VCA Master level at setup
The assignment of VCAs should be done with the channel or group faders and the VCA master, to which assignment
is being made, being at or near a nominal operating level. That is, don’t assign a VCA master to a channel or group if
the VCA master is at -40dB while the channel or group is at 0dB. There are 0dB buttons for VCA masters available in
VCA group conguration mode.
VCA and 'E' Buttons
Fader Pages buttons for mapping VCAs to the Master Bay faders.
The [VCA] button maps VCA masters 1-8 to the eight Master Bay faders. The [E] button maps VCA masters 9-16
to the eight Master Bay faders.
VCA Masters 1-16 can be assigned to any Output Fader page from A to E, along with Bus Output faders using the
User Defined fader page setup. The VCA page cannot be remapped and always contains VCA 1-8.
VCA Masters [ON] Buttons
Master On/Off button for all of the VCA's member channels.
If a channel that was previously on is turned o by the action of a VCA Master [ON]/O button, the channel’s
[ON] button will illuminate in red to distinguish this condition from a manually 'o' channel.
The VCA Master On/O switch itself has only 2 states, and always illuminates red when o, and green when on.
VCA Group Fader
An offset dB level for all channels that are members of the VCA Group.
• When a VCA master fader is moved, the contributing channel fader levels remain unchanged.
• If a channel is assigned to more than one VCA Group, the resultant oset applied to the channel is calculated as
the arithmetic sum of the dB values of each VCA Master.
• Any VCA master fader reaching –infinity dB (fader at lowest position) will set all member channels to –infinity
dB, regardless of other Master fader settings.
• The maximum gain applied to a member channel as the result of the channel fader setting plus osets from
VCA Master faders is limited to +10dB.
VCA Master Solo/Sel
A master Solo button for all of the VCA's member channels.
Depending on the setting of the AUTO button in the Monitor Setup page (SOLO section), activating a VCA Solo
will result in PFL (if the group only has one member channel) or AFL (if the group has more than one member
channel). Otherwise the VCA solo will follow the setting of the PFL/AFL switch in the Monitor Setup page.
