8.11. MENU 31: OPTICAL I/O
Optical I/O can be set to ADAT or S/PDIF Optical.
Note: When Optical I/O is set to S/PDIF Optical instead of ADAT, AES 3 input is
replaced by "Optical" and its front panel BNC input is disconnected.
8.12. MENU 33: AES INPUT DEFAULT CLOCK SOURCE
When any AES or S/PDIF source is used as a reference or as an audio source, it is
automatically used as the default clock source, in that order of priority. If not, the user
can determine in this menu which AES or S/PDIF source to use as the clock source.
This will be used by the DCD-8 primarily for measurements (frequency & phase).
In AUTO mode, the DCD-8 scans through each input and selects the first valid signal it
8.13. MENU 41: INPUT STATUS
Menu 41 displays the rate and phase of a selected input. The rate of is shown in Hz.
The phase, relative to domain A, is shown in degrees (-180º thru 180º). A positive
value indicates that the source is lagging behind domain A, while a negative value
indicates that it is leading ahead of it.
there is no information (e.g. nothing plugged in) then both rate and phase fields will
show "n/a". There is no phase field at all for Video.
The PHASE ERROR LED lights up when the source being observed in menu 41 is out
of phase, which is defined as an error greater than 36º (10%). If the source is drifting,
then the LED will go on and off as the signal goes in and out of phase.
8.14. MENU 42: TERMINATION
This page shows a termination measurement for each of the 8 word clock outputs.
These measurements are not meant to be accurate, but to give an indication.
Ideally, the value displayed should be 75 . If < 48
if < 30
If any output is double or triple-terminated, the
