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.

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, and therefore only uses the Primary Digital Clock to lock the
sample rate for the Dante Master. The Primary Clock on all Dante Slaves will be overridden by the Dante
Clock. If an additional digital input signal is required on a device that is already a Dante slave, this secondary
digital input must be locked using the SRC clock.
The front panel I/O Status 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.

Signal Processing Latency

The information in Table 9-1 lists the total latency for common input-output configurations when the audio
passes through the Module processing. Table 9-2 on page 72 shows the latency when configured as
pass-thru (no Module processing).
