Ops 10–12 • Peripheral Control Vision Operator’s Manual (v12.0 MD)
1. The switcher applies the normal AFV rules to the select which channels, or groups, will
be taken on-air.
2. The switcher checks for preset overrides that will turn channels, or groups, off or on,
depending on how they are set in the Preset Audio bus.
3. The switcher performs the audio transition by fading the Preset channels to their Preset
audio levels. These levels then become the Current audio levels for those channels, or
groups.
Note — When an audio channel is faded off-air by dragging the level to zero on the audio
mixer, that channel will return to the Default level the next time it is taken on-air.
4. The switcher then saves the Current levels of the audio channels that were taken off-air
at the Preset levels for those channels, or groups. These levels will be used as the Preset
levels for the next transition.
Audio Only Transitions
With the audio override custom controls properly set up, it is possible to perform an audio only
transition. This transition does not alter the video signals on the Program or Preset bus, but
transitions the audio crosspoints on those buses.
Use the following procedure to perform an Audio Only transition:
Important — You must hold the Bank button referred to in step one for the entire procedure.
The button must be held to hold the Crosspoint Group in Audio Mixer mode.
1. Press and hold the Audio Bank custom control button to place the bottom Crosspoint
Group into Audio Mixer mode. The crosspoint buttons on this Crosspoint Group are
now audio crosspoints and represent the audio channels that are on-air and will be taken
on-air in the next transition.
2. Select the audio crosspoint that you want to take on-air on the Preset bus.
3. Press Auto Trans on the Transition Module for the bottom Crosspoint Group to
perform the audio only transition.
Note — Audio Only transitions should only be performed once as they will create audio
overrides. In order to properly perform your next transition, you should check the audio
crosspoints and run an Audio Reset Pst custom control to return to AFV.
This completes the procedure for performing an Audio Only transition.
