To start, the user must select Add button to add the number of sources that will be available to the EMC.
In the dialog box, enter the number of sources.
Note: The maximum number of sources that an EMC can currently
upstream router is 240.
5.1. CONFIGURING CURRENT SOURCE
The user now must select a source from the list that has been populated with the number of sources
available to EMC.
Router Index: This is the actual router index on the upstream router for the selected source. Sources
may not necessarily in contiguous blocks on the upstream router. This maps the
logical source of the EMC to the physical input port on the upstream router.
Note: A Router Index MUST only be used once in the EMC Source List. If there are
repeated indexes used this can result in incorrect source status tally on control panels
Identification: This the name of the source and how it will appear on LCD buttons of the control
panels. By selecting the Auto-assign box, the name entered will be copied
automatically to the LCD legend.
5.1.1. Audio Parameters
These are audio parameters the user may want to define on a per source basis.
Video Only: Check this option for sources that do not have any discrete audio associated with
them; this prevents the EMC requesting audio routes of the upstream router when they
are not required. When this option is checked all other audio options are disabled.
Shuffle: This drop-down combo box selects any audio shuffling stores configure in section 4.7
applied to the EMC when this source is selected to the preset or program bus. If no
change is required when this source is selected set this to the first selection
"Unchanged".
Format: This drop-down combo box selects the audio format type for the EMC when this source
is selected to the preset or program bus. If no change is required when this source is
selected then set this to the first selection "Unchanged".
5.1.2. Keyer Parameters
For each source, parameters can be given that change the keying levels that are selected on the preset
and or program bus when this source is selected. The options are to:
Unchanged: Leave the keyer level as it is.
Take Off: Take the selected Keyer Off-Air if this source is selected.
