Leader Clock

In its default state, the M-1620 Pro D uses an internal reference clock for its audio signals. When connected to other Dante® devices, one device is elected the Leader Clock, and the other devices synchronize via network as Followers. This election takes places automatically and does not require any user interaction.

The current state can be observed in the Dante controller, the web remote and the device display:

When receiving MADI signals from other devices, these signals must use the same reference clock as the M-1620 Pro D. This is usually achieved by connecting a MADI or Word Clock signal from the M-1620 Pro D to the other MADI device. The other device must then be configured to use that signal as a reference clock signal.

Alternatively, a device connected via MADI or Word Clock can be used as an external reference clock. This may be necessary when the configuration of the MADI device cannot be changed. The external clock must match the sample rate configured and the M-1620 Pro D must be clock leader.
