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. Check the 
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 may have stage 
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. 
 K1      MUTE. This momentary action switch turns 
all assigned input channels on or off. It acts as a 
remote control for the mute switches on those 
channels. The channel pre-fade, post-mute sends 
are also affected. The mute switches on assigned 
channels light when the group is muted. 
The switch also functions as a solo select when the 
console is in SIP mode or as a group select key 
when in EDIT GROUPS mode. 
The VCA group mute cannot be assigned to a mute 
group or snapshot memory. However, channels 
which have been muted by the group can be stored 
in the memories. 
K2  SAFE / EDIT. This green LED has a different 
function according to console mode: 
Normal No function 
Solo-in-Place The LED lights when the group has 
been made safe from solo-in-place. 
Edit Safes Indicates that the group is safe from 
solo-in-place in SIP mode. 
Edit Groups No action. 
Preview Snapshots No action. 
K3   PAFL. Press this switch to listen to the group 
signal in the headphones or engineers monitor 
without affecting the main outputs. It acts as a 
remote control for the PAFL switches on assigned 
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.
