6.3 Selecting default routing
A facility is provided to load default routing assignments including delay and preset
values for embedder and de-embedder groups, which will be valid for the current
TANDEM-300 installation.
There are three options, ‘Basic’, ‘Total’ and ‘Delay’. The ‘Basic’ option routes directly
without delay whereas the ‘Delay’ option routes via the currently selected audio delay.
Total refers to a composite 'Basic + Delayed' selection.
The ‘Total’ default, which provides a simple way to quickly achieve stored settings for
direct or delayed audio paths, involves the following sequence:
•
'Delay' default is recalled and those settings stored in presets 8 through to 15
•
‘Basic' default is recalled and those settings stored in presets 0 through to 7
•
Factory default values are applied to Silence Detect Delay, Error Level and
AES phase
When the ‘Total’ default operation completes, the audio paths are all routed one-to-one
directly (non-delayed).
Total Defaults should be recalled if the existing routing table has become corrupted or
invalid. This could occur as a result of changing sub-boards or upgrading firmware.
The menu is obtained with MENU lever 6 ON (DOWN), all other levers UP (OFF
)
and
the SEL switch in position B. The display will read ‘Defaults?’. Turn the shaft encoder to
select between ‘Basic Def’, ‘Delay Def’ and ‘Total Def,’.
All three options will attempt to select one-to-one routing (in1.1 to out 1.1, in1.2 to out
1.2 etc) according to the fitted sub-boards.

Use the Shaft Encoder to select Basic, Delay or
Total .
When the desired option is displayed, toggle piano switch 1 down and then up again to
implement the routing.
Recalling any preset 8~15 will reload one-to-one audio routing with delay in every path.
Recalling any preset 0~7 will again reload one-to-one audio routing, but without delay.
Presets may be re-called, 'edited' by changing settings and then re-saved until the required
routing has been obtained. TANDEM-300 applications are unlikely to require simple one-
to-one routing and Audio Group selections for de-embedders ‘A’ & ‘B’, and for
embedder ‘C’ will almost certainly need to be set differently to the default settings.
Note:
Only routing or delay information is recalled with the load ‘defaults’ function. Other
data such as embedder or de-embedder settings remain as they were. It is recommended
to manually check the current group in/out, embedder/de-embedder and mute/invert
settings (card-edge section 6.4).
