Factory defaults
A facility is provided at the card-edge to load ‘factory defaults’ for routing, delay and
preset data into TANDEM’s non-volatile memory. It is strongly recommended that the
appropriate factory defaults be loaded after any of the following:
•
whenever sub-PCB cards have been changed
•
at any time card edge or other menus appear corrupted
Please refer to the Statesman ‘Recalling Defaults’ or the card edge section 6.3 for details
of the available factory defaults that may be recalled.
Note:
Always check that the appropriate groups are selected for embedding or de-embedding
after loading defaults (refer to Statesman ‘Audio Routing’ or section 6.4 for card edge
controls).
Monitoring
TANDEM-300 is equipped with two monitoring outputs:
•
analogue headphone output
•
analogue or AES rear connector output
The rear connector output is fed from a monitoring ‘bus’ that may be switched between
OFF (silence or high impedance), a copy of the analogue headphone output or an
automatically assigned AES output. The rear connector monitoring may be used to extract
a ‘breakout’ monitoring quality output, when an output option card is not fitted.
The analogue output can be manually selected as adjacent pairs or routed using the in-
built routing to extract non-adjacent signals from the same group.
The AES output monitors the following audio:
•
de-embedded audio if a Demux (de-embedder) is enabled
•
audio routed to an output option card if the Demux (de-embedder) is disabled
•
audio silence if Demux (de-embedder) is disabled no output option-card is fitted
Note:
The analogue monitoring output can provide a Demux output even if an output option is
not fitted.
Setting all but a selected card’s monitoring BUS to OFF allows multiple TANDEM or
Demon cards to be selectively monitored.
The AES monitoring bus may be used for re-processing. AES signals can be fed to a
gain control, compressor or other process and then fed back into a digital input card for
further TANDEM processing or routing.
