Audio Follow
Video Audio Follow Video determines whether audio settings are remembered for each
video input. When AFV is On, The FS2 remembers the saved audio settings
associated with the currently selected video input. Whenever a new video input is
selected, the corresponding audio settings are recalled. This allows you to set up
specific audio settings for the different video inputs.
When AFV is Off, you must manually select the audio you want for a selected video
input, and that audio source remains selected until you change it. If the audio
source has never been selected, the factory default audio source is used.
Audio Follow Video applies to these parameters:
• 1 Audio Input
• 1.1—1.16 Audio Map
• 1.17—1.24 Audio Map (Stereo)
• 6.0 Audio Delay
• 7.0 Audio Output Levels
• 7.1—7.16 Audio Level Ch (n)
• 8.0 Audio Output Phase
• 8.1—8.16 Audio Phase Ch (n)
Turning Audio Follow Video (AFV) On results in the loss of the above settings.
When AFV is turned On, the source-memory settings are written over the current
settings. Turning AFV Off again will not restore the original settings, but instead
will result in the source memory settings remaining in effect until edited again.
Audio SG Audio SG determines the audio signal output from the FS2’s internal test signal
generator.
(3) Audio Follow Video Selections Selection Descriptions
Off (default)
On
Normal operation. Audio settings must be made separately
from any video settings; they are not associated
automatically.
The FS2 remembers the saved audio settings associated
with the currently selected input. Whenever an input is
selected, the corresponding audio settings will be recalled.
This allows you to set up specific audio settings for the different video
inputs (i.e., perhaps the SDI 1 has a specific embedded audio channel
mapping while the component video input might always use AES
audio input).
