Working with Voice-Overs
Imagestore 750s have two voice-over mixers: Over 1 and Over 2. The “layer” section of the
program 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 –99.9 dB to +28.0 dB).
Each voice-over has its own set of levels. The physical audio level knobs adjust these parame-
ters. The knob labeled ‘Duck Level’ adjusts the “duck” level. The knob labeled ‘Gain/Voice-Over
Preset’ adjusts the over level.
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.
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:
1 Press the desired VO button(s) on preset. Selected VO buttons are high-tally.
On preset, the VO buttons have 3 states: cut, fade, and off. Press the button again to cycle it
to its next state. When the state is ‘cut’, the VO cuts to the program bus during the next tran-
sition and when the state is ‘fade’, the VO fades (at its current rate) to the program bus.
2 Optionally, set up other video effects, and transition type and rate.
3 Press the Transition button.
To remove voice-over(s) from program, press the desired VO button(s) on the preset bus to dese-
lect them and perform a transition in the normal way. Here too, the VO buttons have 3 states:
cut, fade, and off. When the state is ‘cut’, the VO cuts from the program bus during the next tran-
sition and when the state is ‘fade’, the VO fades from the program bus.
Please note: you can “hot cut” VOs directly on and off the program bus at any time , as required,
simply by pressing the desired VO on the program bus. Hot cuts are not recommended.
Hot cuts have side effects on the preset bus, depending on which transition options are active in
the currently selected Imagestore 750.
