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:
•
a change of Mode
•
whenever sub-PCB cards have been changed
•
at any time card edge or other menus appear corrupted
Please refer to section 9.3 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 section 9.4 for card edge controls).
Monitoring
TANDEM-200 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.
