Basic Operation
This chapter describes the general operation of your
switcher. Basic information is provided to help you
become familiar with switcher operation.
Transition Overview
Transitions allow you to replace the on-air video
source with another source. During a transition, the
source you selected on the Preset bus becomes active
on the Program bus and the source that was active on
the Program bus is now active on the Preset bus.
You can perform the following types of transitions:
• Cuts — The video image instantly switches
between selected sources.
• Dissolves — The video image gradually fades
from the on-air source to the selected source.
• Wipes — The selected source wipes over the
on-air source using a user-specified pattern and
direction.
• DVE — The video image is taken off-air using a
selected digital video effect.
• Media — The video image cuts to another video
image behind a playing animation or still.
Note:
• If any of the inputs going on-air have an assigned
GPI output, the GPI output is triggered and the
switcher then waits the configured pre delay
interval before performing the transition. If you
perform a transition with the fader handle, the GPI
output is triggered but the pre delay interval is
ignored.
• If any of the inputs going on-air are assigned to a
video server, the switcher waits for the configured
pre delay interval before performing the transition.
If you perform a transition with the fader handle,
the pre delay interval is ignored.
For More Information on...
• assigning a GPI output to an input source, refer to
the section “Triggering GPI Outputs” on
page 4-15.
Performing a Transition
A transition can be performed on almost any
combination of the background and keyers,
depending on the type of transition you are
performing, and what you are transitioning. These
factors include the number of media resources you
have, and if you are trying to perform a background
and keyer transition at the same time.

1. Select the elements to include in the next
transition by pressing any one of the following:

2. Select the sources that you want to take on or
off-air.
• For a background transition ( BKGD ), select
the source on the Preset bus, that you want to
take on-air. The selected source appears on
your preview monitor.
• For a key transition, select the keys and
sources on the Key/Aux bus that you want to
take on-air.

transition.
4. Perform the transition by choosing one of the
following:
• Press CUT to immediately cut the
