9.4 Control Groups or Multi Format Masters
This section presents general information to help decide whether to use a Control Group
or Multi Format Master for a given task.
If you need to adjust individual parameters on the slave channels, use a Control Group.
Multi Format Master channels are set up with all functions on the slave channels
switched in. Therefore, adjusting the EQ on the Multi Format Master channel affects all
the slave channels. Adjusting parameters on the Control Group Master affects the slave
channels only if that function is switched in at the slave when the Control Group was
created or subsequently. For example, adjusting EQ on a Control Group master has no
effect on the slave channel unless the slave channel’s EQ is switched in.
If a VT is playing a stereo format, use a Multi Format Master because they include ded-
icated stereo functions: LTM, RTM, Balance and Swap (see Stereo Controls on page
103).
If the VT is playing dual mono signals (i.e., dialog and music), use a Control Group or
just two mono channels because you may want to apply different EQ and compression
settings to each signal. Use a Control Group to control multiple mics on a similar source
(i.e., crowd or drums).
To summarize:
• True stereo source: Multi Format Master (do not adjust the slave channels)
• Dual mono: Control Group (adjust functions on the slave channels)
• Multiple similar signals: Control Group (adjust functions on the slave channels)
