Synchronisation
Sync Reference Options
The sync reference options are:
·
PTP
- from the AES67/RAVENNA streaming network.
·
Wordclock
– connected to WCLK IN on the front panel.
·
MADI
– incoming MADI from front panel port 1 (or port 2 if redundancy is configured and port 2 is active).
Note that other MADI ports cannot be used for synchronisation.
·
Internal Clock
– 48kHz or 44.1kHz.
Each of the external sync options listed above can be independently enabled or disabled. If disabled, POWER
CORE will ignore the sync source even if it receives a valid signal. It is possible to enable one or multiple sync
options for the device.
If multiple external sync options are enabled, then it is possible to choose a priority order for PTP, Wordclock and
MADI. The device will then always use the highest prioritized sync source. If none are present, then the device will
default back to internal clock. The switching between the enabled sync options and internal clock is handled
automatically.
By disabling all external sync options, POWER CORE can act as a sync master and distribute its internal clock
via PTP, Wordclock or MADI to other devices.
Please note
: if POWER CORE has been synchronized once to a PTP master, then it will NOT automatically
switch to another sync source but try to re-establish its connection to the external PTP master. While doing
this, it becomes PTP master itself, and uses the pre-aligned internal clock as the reference.
In the configuration, the external sync options are enabled (or disabled) in the
branch of the ‘Tree Definition’. From here you can also set the internal sync generator to
run at either 48kHz or 44.1kHz.
Checking the Sync Status
The sync status can be checked from the front panel by looking at the STATUS LED:
Front View
The LED should be blinking at regular intervals; the color then indicates:
·
Blue
, blinking = synchronized to PTP master.
·
Yellow
, blinking = attempting to sync to PTP master.
·
Green
, blinking = synchronized to Wordclock.
·
Magenta
, blinking = synchronized to MADI.
·
Red
, blinking = synchronized to internal clock.
If the LED is not blinking, then there could be a problem with the system. See the
