Synchronization
On the Synchronization tab, you can configure different synchronization options for the device.
System Sample Rate
You can adjust the sample rate of a device to 48 kHz or 44.1 kHz.
Even if the device works with external synchronization, you have to set the correct sample frequency here, because the internal Quartz PLL can not adjust correctly to the external clock otherwise.
Synchronization Sources
You can define two synchronization sources on 52/XD2, 52/XD, 52/XC2 and 52/XC cores - Sync Source and Sync Source 2. On 52/XS and 52/XS2 cores you can configure only one sync source.
The source configured at Sync Source is the primary synchronization source. If this sync source fails, the system automatically changes to the source configured in the Sync Source 2 list. If the second sync source fails too, the system switches to the internal clock of 48 kHz or 44.1 kHz, depending on the selection above.
Sync sources can only be signals that are connected directly to the core. Cores with integrated MADI interface (52-7321, 52-7325, 52-1821 or 52-1825) can sync to that source. Otherwise an external BNC sync needs to be connected. The type of BNC source signal has to be selected on selecting source.
Also direct APC links or Gigabit Audio (GA) links between DSP Cores can be used as a sync source.
