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.

Cutting on the Program Bus
Cuts are the simplest transition, performing an
instantaneous change between sources. You can
perform a cut transition by pressing CUT, or you can
perform the transition directly on the Program bus.
This also applies to keys. If a key is on-air, you can
select alternate sources on the Key/Aux bus and
have them instantly cut on-air.
