6.4 Audio routing
Routing audio on the TANDEM-300 involves selecting valid audio sources and
destinations. The available options depend on the sub-boards that have been fitted and the
mode selected.
Changing or establishing new Routing settings involves the following steps:
•
Select appropriate groups for de-embedding and embedding
•
Select appropriate sources and destinations
Tip:
If TANDEM-300 firmware or sub-boards have been changed it is recommended to start
by loading valid default settings for the entire routing table held in TANDEM’s non-
volatile memory. This will prevent erroneous settings from appearing in the routing
assignment menus. Please refer to the previous section (6.3) if default settings are
required.
Selecting groups
When embedding or de-embedding, the source and destination groups should be selected
as part of the audio routing setup. This is accomplished using the status display; Menu
switch with all levers OFF (UP). The SEL switch selects each side’s de-embedding or
embedding functions and the ADJ shaft encoder selects the available groups. Save the
group assignment by toggling MENU switch 1 down and then up again.
The above table summarises the available source and destination group assignments.

No.

Note:
Remember that the ‘=’ sign before a group number indicates an existing group already
present in the incoming SDI signal.
When embedding, a space just before a group number, ‘ ’n, indicates a non-existent
group or new group to be formed.
