Transition Controls and Operation
Audio/Video Breakaways
Transitions can be tailored to change only selected signals using the Mode
(Audio and Video Breakaway) transition selections ( Figure 2-6 ). Normally,
audio and video signals are transitioned simultaneously. The Audio Only and
Video Only buttons are used to perform program and preset bus breakaway
source selection. These buttons transition audio only or video only signals
as described below:
■ Audio Only —when selected, the next transition will change only the
audio portions of the on-air signal.
■ Video Only —when selected, the next transition will change only the back-
ground video portions of the on-air signal.

Pressing either the Audio Only or Video Only button causes it to toggle between
its active and inactive state. Preset selections made while the Audio Only or
Video Only button is in the active state (lighted), unless the button is held,
will be restricted as indicated. If an Audio Only or Video Only button is active
when a Preset selection is made, the Audio Only or Video Only button will
toggle to its inactive state automatically.
