Working with Voice-Overs
Note that when this option is enabled and you select XG layers on PGM, the DSK is also
selected on PGM. Consequently, the XG layers appear on air. When this option is disabled and
you select XG layers on PGM, you can select a DSK on PST to view the XG layers.
• ‘Slave keyer follow down’.
This option can be enabled or disabled.
When it is enabled, the default DSK turns off automatically when no XG layers are selected.
When this option is disabled, the default DSK is not affected by XG layer selections.
Consult your system administrator to determine how your Imagestore 750s are configured.
Working with Voice-Overs
Imagestore 750s have two voice-over mixers: Over 1 and Over 2. The “layer” section of the pro-
gram and preset button rows can include 0, 1, or 2 voice-over buttons.
There are two parameters that govern the use of voice-overs: the “duck” level and the over level:
Both of these values are expressed in decibels (in the range –100.0 dB to +28.0 dB).
Each voice-over has its own set of levels.
There is an ‘Over Ratio/Duck Level’ knob. When the panel is controlling an Imagestore, and a
voice-over is selected on program, the knob controls the “duck” level of voice-over on program
output. If both voice-overs are selected on program, the knob adjusts the duck level of both voice-
overs. This control affects the on-air signal.
There is a ‘Program Out’ knob. When the panel is controlling an Imagestore, and a voice-over is
selected on program, the knob controls the over level of the voice-over on program output. If both
voice-overs are selected on program, the knob adjusts the over level of both voice-overs. This con-
trol also affects the on-air signal.
Voice-over sources are defined in the Imagestore 750 configuration. When voice-over accepts
EasyPlay clips, you can select different clips using the EasyPlay menus.
The voice-over mixers can also accept input from the Imagestore 750’s AES inputs. Choosing
audio clips from external media is outside the scope of this manual, but it will probably involve
loading, cueing, and pre-rolling different media.
The use of voice-overs is affected by certain transition options. See Transition Options on page 107
for more information.
Performing Transitions with Voice-Over
You can transition voice-overs to (or from) program output.
Follow these steps to transition one or more voice-overs to program output:
