Synchronization
Sync Reference Options
The available sync reference options are:
·
PTP
- from the RAVENNA/AES67 streaming network.
·
Wordclock
– connected to WCLK IN on the front panel.
·
MADI
- connected to the active
MADI
port: either MADI 1 or 2 on the Power Core front panel.
·
Internal Clock
– set to 48kHz or 44.1kHz by the configuration.
All options are always enabled and so the system will use the highest prioritized sync source (if a valid signal is
present): PTP, WCLK, MADI, or internal. The switching between external sync and internal clock is handled
automatically.
If external sync is not available, then Power Core can act as a sync master and distribute its internal clock to
other devices (via WCLK OUT).
The internal clock generator defaults to 48kHz, but this can be changed to 44.1kHz from the DisplayDock GUI
(as described below).
Checking the Sync Reference
The available and active sync sources can be checked from the DisplayDock
"CLOCKING" area):
The "SYNC" fields are indicators only; you cannot change the sync source from the GUI: red = active; blue =
available. In our example, the active sync source is
INTERNAL
.
Changing the Sample Rate
The sample rate of the internal clock generator can be changed from
48kHz
to
44.1kHz
, or vice versa, when all
faders are closed (off-air) and UNLOCK (on the Central Module) is pressed.
Note that this operation is only possible when all faders are closed (as the change would be audible if it was
permitted while on-air). In this instance, the button colors update to red = active and blue = inactive but
available. Select the inactive (blue) option to make the change.
After a cold start, the internal generator will reset to the default value stored in the configuration (48kHz).
Sync Output
The WCLK OUT
connector always provides an output of the current system reference.
