Broadcast Routes
It is easy to route a source to multiple destinations for audio and video routers. You place the
panel in hold mode with the hold button.
In contrast, machine control routes are typically point-to-point. Therefore, to control multiple
machines requires that you perform a “broadcast” operation using a ‘Broadcast’ button.
In “broadcast mode,” the source device issues control commands to all destination devices —
but only one destination (the first one you connect to the source) can respond with status.
Broadcast routes can be performed in either mode.
 “Broadcast” routes are those that involve machine control. An NVISION series machine
control router such as the NV5256 is required.
Before You Begin
1 Ensure that all devices that you want to include in the route are not locked or protected —
and that their machine control levels can be acquired.
2 Ensure that the panel has a ‘Broadcast’ button. If it does not, broadcast routes are not possi-
ble. Consult your administrator.
3 Ensure that your data router has been configured as “data forward.” In this mode, the router
expects the source (e.g., playback device) to control the destination (e.g., recording device).
4 Cue your playback device. (After the take, you must manually start the playback.)
Performing a Broadcast Take
Follow these steps:
1 Select a destination and route a source to it. The source becomes the master because the
router is in data forward mode. This destination is the slave and communicates bidirection-
ally with the master on the machine control level.
2 Press ‘Broadcast’ (so that it is high-tally).
3 Choose a destination and route the same source to it. This destination only receives control
commands; it will not return status.
4 Repeat steps 2 and 3 to connect additional slave destinations.
5 To remove one slave from the group, turn off ‘Broadcast’ and route a source to it that is not
the master (e.g., the free source). This new device must have a machine control connection.
6 To clear the entire broadcast route, turn off ‘Broadcast’ and select the master device as the
destination in a new route. (We recommend that you use the free source as the new source).
The entire broadcast route is cleared, and data connections are removed from all slaves.
Important Points
• After you perform the complete take, you must start the playback of the source device man-
ually.
• The panel provides no way to determine which devices belong to the “broadcast group.” You
must keep track of this yourself.
• If another operator takes either your master device or the first slave device, the entire broad-
cast group collapses. Any other slave can be removed from the group, however, without col-
lapsing the entire group. Only the primary pair is critical to the group’s integrity.
