Recalling defaults
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 recalls all factory defaults for all parameters including the 'Basic + Delayed' routing
parameters.
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).
It is recommended that Total Defaults are recalled after a Mode change or if option-cards
have been changed.
Total Defaults should also 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.
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.
