IS2/3 Emulation Mixfiles
is23.mix & is23eply.mix
For the IS2/3 emulation mixfiles, a ‘group’ refers to a collection of four
mono inputs. Mixing occurs between the group currently selected for
Program (PGM) and the group selected for Preset (PST). Further still,
selectable cross-points for each channel allow mapping of both groups for the
mix.
The operation of the IS2/3 emulation mixfiles remains unchanged compared
with earlier versions of the Imagestore software. However to improve
usability (especially as part of a PresMaster based Master Control
environment) the following features are now supported:
Program output meter tracking
Program output meters 5-8 track the master output level.
Voice-over preview meter tracking
Voice-over input previewing tracks the gain applied to the voice-over inputs
without the voice-over being on-air.
12 channel pass-through
Embedded audio on groups 2-4 passes through to output groups 2-4
regardless of which input group is active for the AB mix.
Group sensitive previewing
As the active group changes within the audio engine, the input previews track
to display the correct inputs.
Note Due to the way these are implemented within the mixfile
interface these features only apply to is2/3 emulation mixfiles.
