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.
To perform a transition:
1.
Select the elements to include in the next
transition by pressing any one of the following:
•
BKGD
•
KEY 1
•
KEY 2
•
KEY 3
(KM-H3000 only)
2.
Select the source on the Preset bus (when
BKGD
is selected as part of the next transition),
that you want to take on-air. The selected source
appears on your preview monitor.
3.
If you selected any keys for the transition in step
1, select keys and sources on the Key/Aux bus.
4.
Choose the type of transition you wish to
perform:
• Press
DISS
to select a dissolve transition.
• Press
WIPE
to select a wipe transition.
• Press
DVE
to select a DVE transition
5.
Perform the transition by choosing one of the
following:
• Press
CUT
to immediately cut the selected
source on-air (selected transition type is
ignored).
• Press
AUTO TRANS
to have the switcher
perform a smooth transition.
• Move the Fader from one limit to the other to
perform a manual transition..
Note:
• You can select multiple elements for the next
transition by pressing and holding the button for
the first element, then pressing one or more of the
other next transition buttons.
• While still holding the first element button, press an
element button again to remove it from the next
transition.

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.
