Using VCA Groups
Use audio groups where you want to insert group
signal processing or send groups of signals to the
matrix. Use VCA groups if you want grouped level
control only.
Route the channels to the mix by pressing the MAIN
MIX switch C1 . Adjust the PAN and BLEND
controls for the image required. Assign the channel
to the required VCA group using the edit groups
routine described on the next page.
channel VCA assign LEDs next to the fader for
correct assignment. Once assigned, the group
fader affects the channel level. Start with the group
fader set to its nominal '0' position.
You can assign the channel to more than one
group. Take for example a theatre musical
production. Here, you
microphones assigned to Group 1, radio mics to
Group 2, and all microphones to Group 3. You may
also have all channels assigned to Group 8 as a
'grand master' to control the overall volume. In this
case, a radio microphone would be assigned to
Groups 2, 3 and 8. Note that the VCA groups affect
all channel post-fade sends such as effects and
direct outputs but not the pre-fade monitors.
Refer also to section M for details on storing the
channel VCA group assignments in the snapshot
memories.

channels. It actions either all channel PFL or stereo
AFL in-place depending on the setting of the master
section INPUT PAFL switch P2 .
Using PAFL
Set the master section INPUT PAFL switch for
either PFL or stereo AFL in-place when you select a
VCA group PAFL.
Use PFL to check for signal presence while the
group fader is down. This is useful when you need
to check that all is well before raising the fader and
bringing the assigned channels into the mix. The
channel PFL switches are turned on and the signals
mixed together at the same level. Turn down the
master PFL TRIM control N1 if the signal is too
loud in the monitor.
Use AFL to check the balance and contribution of
the group of channels to the mix. The signal follows
the fader levels and image controls with C mixed
into the L and R so that you can listen to the LCR
mix in stereo.
