12.3 Group Masters
A “group master” must be designated in order to control the faders, mutes, and inserts on other
channels.
Any fader on the console, including the channel faders, the two Control Group Master faders (G1-
G2), and the Program Master fader (PGM) may be designated as a “Group Master Fader” or simply
“group master.”
Any channel and either of the two Control Group Master faders (G1-G2) may be designated as
group master for mutes. Mutes cannot be controlled from the Program Master fader (PGM).
Any channel and/or the Program Master (PGM) may be designated as group master for inserts.
Inserts cannot be controlled from either of the two Control Group Master faders (G1-G2).
Channel Fader
Channel Group Masters faders, mute, and inserts are fully automatable and can be set up to
control faders, mutes, and inserts on their assigned “Member” channels.
Control Group Masters
Any 548B input channel can be designated as a “Group Master Fader” for faders,
mutes, and inserts. It’s common to use an unused channel as a Group Master,
but any fader, including one carrying audio, may be used. If the Group Master is
passing audio and is adjusted (i.e. fader change or mute), it will affect the group
Members as well as its own audio.
An advantage of using channel faders as masters is the ability to locate a Group
Master near the Members it controls. Channel Group Masters can also control
channel inserts.
The two (2) Control Group Master Faders (G1 & G2) on the
Automation Controller that can be designated as Group Masters for
faders and mutes.
Control of inserts is not available from the Control Group Master
Faders (G1 or G2).
These Control Group Masters are control devices only and cannot be
used to carry audio.
An advantage of using the Control Group Master is they do not use
any channel resources and are located next to the Program Master
Fader.
Control Group Master Faders and mute are fully automatable and
can be set up to control faders and mutes on their assigned
“Member” channels.
The MUTE switch on the 548B Input Module is typically used as
the “Mute Group Master” when that channel is designated as a
“Group Master Fader.” However, mute groups can be set up
independently of fader groups.
The MUTE switch on the G1 and G2 masters is
typically used as the “Mute Group Master” when that
fader is designated as a “Group Master Fader.”
However, mute groups can be set up independently
of fader groups.
The INSERT switch on the 548B Input Module is typically used as
the “Insert Group Master” when that channel is designated as a
“Group Master Fader.” However, insert groups can be set up
independently of fader and mute groups.
