Program Master
IMPORTANT NOTE: If the Program Master Fader (PGM) is used as a Group Master in addition
to carrying the program audio (mix), the level of Member Channels will be
doubly affected when the Program Master Fader is moved. If the Program
Master is moved downward, the contribution of Member Channels to the
Program Bus will be attenuated as well as the Program Outputs of the
console. The result will be a decreasing amount of Member Channel
contribution to the mix as the mix is faded. The Member Channels will
effectively “disappear” from the mix towards the end of a final fade.

The INSERT switches on the 548B Input Modules and the PGM INS (Program Insert) in the
268B Program Master Module can be a Master or Member of a group. The input channel and
program master inserts cannot be controlled from the Control Group Master faders (G1 or
G2) since these faders do not have inserts.
The Program Master fader on the Automation Controller can also be designated
as a Group Master for faders and inserts.
Control of mutes is not available from the Program Master Fader (PGM).
Program Master Fader feeds the console Program Outputs, so it is not commonly
used as a “Group Master Fader.”
The Program Master Fader and insert are fully automatable and can be set up to
control fader and inserts on the assigned “Member” channels.
Any 548B Input module on the
console may be designated as an

common practice to use an unused
channel as a Group Master, but any
channel, including one carrying
audio, may be used.
