Default Routing
Unlike video or audio matrices, data routers (also called “port” routers or machine control routers)
allow only point-to-point connections. For editing, Miranda port routers also allow point-to-multi-
ple-point connections. (Machine control connections are for dubbing, cue tone distribution, to roll a
backup VTR, etc.)
When connections are point-to-point, there are some operational issues. For example, if an editor in
one suite selects a VTR that is currently in use in another edit bay, he or she will break the RS-422
data connection to the edit controller, and disrupt the edit. It would be better if the control level
could be separated from the other levels. The NV9000 provides this separation in two of the three
different data modes: semi-automatic and manual.
The following are the data modes:
• Automatic mode. Control level switches automatically follow with the other configured levels.
• Semi-automatic mode. The new source will be routed on all levels — except control. The oper-
ator is prompted to press
Take
again, if the route on the control level is desired. Pressing
Clear
Preset or waiting for the preset to time out cancels the control level route. This is the recom-
mended mode for most applications.
• Manual mode. All switches performed on the control level between ports that are currently in
use are performed as separate takes, providing some degree of safety.
Modes of Operation
Depending on the control panel, it may have several modes of operation. Depending on the config-
uration, the modes for routing signals are X-Y mode only, MD mode only or both X-Y and MD. A
single button labeled ‘XY/MD’ toggles between the modes.
Other modes provide access to salvos, control panel settings and system information. Depending on
the control panel, not all of the modes are available.
X-Y Mode
X-Y mode provides full router control of sources and destinations. Any single source (X) can be
routed to any single destination (Y). In this mode, to perform a “take,” (1) choose a destination, (2)
choose a source, and (3) press
Take
to complete the route.
In X-Y mode there is full control of all levels. A level typically represents a single signal type used
in your system, such as AES or HD. (See
About Levels and Level Sets on page 112.) The display
area shows up to eight levels. If additional levels are available, press Page Up or Page Down to view.
Optional breakaway levels may also be selected. A breakaway is a subset of levels that may be
selected for a “take” from the list of available valid levels. For example, if a destination device is
assigned to levels HD, SD and TC, you can select to route to only HD. By default, all valid levels
are selected for a “take.” To route to only a subset—to “breakaway”—the levels must be specifi-
cally selected. For more information, see
About Breakaways on page 359.
Multi-Destination (MD) Mode
MD mode enables the operator to route one or more sources to multiple destinations at one time. In
this mode, the operator (1) chooses a destination, (2) chooses a source, and (3) using the
