4.3 Audio routing and processing options
Routing audio on the TANDEM-110 involves selecting valid audio sources and
destinations. The available options depend on the sub-boards that have been fitted.
Tip:
If TANDEM-110 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. From firmware V5.15 this function is performed automatically (card-
edge display shows Save Pre15 > Pre1). Please refer to the previous section (5.2) if
default settings are required.
Changing or establishing new Routing settings involves the following steps:
Select appropriate groups for de-embedding and embedding
Select appropriate sources and destinations
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 follwing table summarises the available source and destination group assignments:

No.

Notes:
Remember that the ‘=’ sign before a group number indicates an existing group, when
embedding a space before a group number, ‘ ’n, indicates a non-existent group or new
group to be formed.
E and F replace C and D respectively, if there is no analogue or digital input sub-board.
