Preview Bus
The preview bus is used to select a source on the preview output. This source is sent to
program when the next transition occurs. The selected source is indicated by a button that is
illuminated green. A blinking green button indicates that the shifted source is on preview.
Pressing the SHIFT button will display the shifted source.
SHIFT
The SHIFT button provides a global shift and is used to shift the program, preview and
select busses along with source labels. It also provides a shift for the transition type
and joystick and other menu functions.
Double-pressing buttons in the preview, select and destination busses, as well as the
transition style buttons, is the same as shift-selecting them and can be a faster way to
shift-select buttons. Double-pressing is not implemented for the program bus as it
would cause the program output to momentarily show the wrong source.
Destination Bus and Select Bus
The destination bus gives you 1 key access to make changes to sources in your cuts and fills,
borders and dip colors, stinger fills and cuts, DVE logos and cuts, and down stream fills and
cuts. To assign a source to one of these destinations, select any destination in the Destination
bus and make your source selection in the Select bus below it.
The destination bus works in conjunction with the source names display and select bus to
assign sources to auxiliary outputs and keyers.
The source names display and select bus together show you the routing of sources to keys and
auxiliary outputs. The currently selected source is indicated by an illuminated button. A blinking
button indicates a shifted source. A green illuminated button identifies a protected source.
Protected sources are program, preview, clean feed 1 and clean feed 2.
DEST SHIFT button
To access the shifted destinations in the destination bus, hold down the DEST SHIFT
button at the right side of the bus and make your selection.
CUT/KEY
When a key setup menu is selected and a CUT/KEY button is pressed, the select bus
changes to show the currently selected cut signal (also known as the Key signal) for that
key. When selecting sources for auxiliary outputs, pressing the two SHIFT buttons
displays program, preview, clean feed 1 and clean feed 2 as sources for selection on
the select bus.
Auxiliary Outputs
Aux crosspoint buttons are located in the M/E 2 destination bus. They can be used with an
ATEM switcher which has aux outputs and which has been assigned to the M/E 2 block. Select
the aux number in the destination bus, and then select a source for it in the M/E 2 Source Select
bus. See the later section “Using Auxiliary Outputs” for the many uses of auxiliary outputs.
The M/E 1 block doesn’t have aux buttons. If an ATEM production switcher is assigned to the
M/E 1 block, you can still access the aux outputs through the M/E 1 system control block. From
any menu, select HOME and then AUX and you’ll see the aux outputs are numbered. Select the
aux output you wish to change and then select a new source for it in the Source Select bus.
