preset source for the destination. The middle line of text is blank when you have not preset a
source. The bottom line of text is the destination name.
• In X-Y mode, the top left button of the NV9616 represents the selected destination. Similarly,
the left button of the NV9608 represents the selected destination. Any remaining buttons repre-
sent levels. Not all levels necessarily apply to the selected destination. Those that do apply can
be selected and those that are selected are high-tally.
The text on the destination button varies. The top two lines usually read “X - Y” and “DEST”
respectively. The bottom line is the destination name.
The top line of buttons that represent levels is the current source for that level. The middle line
is the preset source for that level. The middle line of text is blank when you have not preset a
source. The bottom line is the level name.
• In menu mode, the button text varies according to the button function.
• In salvo mode, the button text is the salvo name.
Operating Concepts
Levels
In the NV9000-SE Utilities and in the NV9000 router control system, routes occur on levels. A
level is typically SD, HD, analog video, AES, analog audio, or machine control. Various devices
are defined as sending and receiving signals on certain levels. The set of levels handled by a device
belong to what is called a level set.
A source can be routed to a destination if it has the same set of levels, i.e., it belongs to the same
named level set. A source can be routed to a destination in a different level set if the NV9000 con-
figuration has the appropriate level mapping.
The effect of this is that when you, the operator, choose a destination, the NV9000 recognizes
which source devices are allowed to be routed to the destination and limits your selection to those
sources.
Breakaway
Routes can be all-level in which case they are taken on all levels defined for the destination. The
acceptable sources for a route have the same levels as, or some configured mapping to, the levels of
the destination.
A breakaway is where you take different sources to the same destination — on different levels.
It is not possible to take different sources to the destination on the same level. For instance, you
cannot take SD from two different sources. The outcome would be noise even if you could do it.
(That is because routers are not mixers.)
Hold
Hold mode (and hold buttons) apply in both X-Y mode and multi-destination mode.
A hold button is also called a ‘Hold Preset’ button.
