Output Gain Types
Each output can be assigned a cross-point gain type. The gain type defines
the behaviour of the particular output as used in the conceptual model. If no
gain type is specified, the output audio will be UNITY (unchanged).
PROGRAM_GAIN Modify output gain by the
value of the Program gain.
PROGRAM_GAIN
The PROGRAM_GAIN type will modify the output’s gain by the value of
the program gain (set with the j103 automation command). Any channels that
are required to be modified by the program gain should be set to this gain
type. Additionally, if metering is required to reflect the program gain’s value,
any meters assigned to program outputs should also be set to this gain type.
Destinations
Each mix can be mapped to any number of destinations, however, each
destination can only come from one mix. An example destination would be
the left-hand channel of AES output pair 5 (AES_O_P5_L) or one of the 64
metering points.
A full list of output destinations can be found on page 232.
Mix File Commands
The mix file is constructed from a series of commands, which are used to
create mixes. The order of the commands is important. Commands can be
separated from their arguments by one or more spaces or tabs. Comments can
be included in the mix file on a line starting with a ‘#’ character. Blank lines
are ignored.
