10.7.2. Clock Source Priorities
There are two options for clock source configuration: Manual Configuration or Automatic Detection.
For Manual Configuration, the selected internal or external clock source remains fixed regardless of whether a
compatible clock signal is preset.
For Automatic Detection, the most appropriate clock matching the selected base-rate is automatically selected
according to the following priorities.
1. AES1 (Input 1+2)
2. Internal Clock
When using automatic detection, the AES3 digital input is monitored and will switch the clock source back and
forth depending on the availability of an AES3 signal. Please refer to the Lake Controller Operation Manual for
additional information.
10.7.3. Dante Clock Configuration
Dante uses its own digital clocking technology across the Ethernet network to ensure that all Dante devices are
synchronized. As part of this logic, an order of priority is defined to identify which device becomes the Dante
Master. A Dante-capable device set as Preferred Clock Master is chosen as the highest priority, followed by a
device with a valid AES3 signal, then an internally generated clock.
Dante only operates at 48 kHz or 96 kHz, with the PLM+ digital clock on all Dante Slaves being overridden by the
Dante Clock.
The front panel Input View indicates if that device is selected as Dante Clock Master. Confirmation of Dante
Master / Slave status is also displayed in the Lake Controller. The Dante Preferred Master setting can be set from
the Lake Controller I/O Configuration screen, or via the Dante Controller. For further information on Digital Clock
configuration and the Lake Controller user interface, please refer to the Lake Controller Operation Manual.
