Note: If device A is deriving its clock from an external word clock source ('Enable Sync To External'), but device B is set as Preferred Leader, device A will lose sync with the Dante network and will eventually be muted - unless device B is also deriving its clock from the same external source as device A.Ĭlock Status Clocking and Synchronization in Redundant Networks
#DANTE VIRTUAL SOUNDCARD CLOCK SYNC UNLOCKED MAC#
If more than one device has 'Preferred Leader' set, the device with the lowest MAC address will be chosen. A Dante device with 'Preferred Leader' set will always be chosen as the PTP Leader Clock. Sometimes it may be necessary to force a particular device to provide the PTP Leader Clock. A Dante device with this attribute set will become the PTP Leader Clock, unless there is another Dante device present with 'Preferred Leader' set. Clock Settings Enable Sync To ExternalĪ Dante device set to 'Enable Sync To External' will use the external word clock from its host equipment to tune its onboard VCXO. In the case of Dante Virtual Soundcard, the computer’s clock will be used. Dante Clock TypesĮach Dante hardware device can derive its clock from either its high-quality onboard clock circuit, or an externally connected word clock. The election process may be overridden by manually setting 'Preferred Leader' on a device. A tie-breaker rule of the lowest MAC address is used if several equivalent candidate leader clocks are available. A gigabit connected device is preferred over a device connected via 100Mbps. Word Clock or AES3) will be preferred in the election process. Although many Dante devices may be capable of becoming PTP Leader Clock, only one device will win the election. One Dante device will be elected as the PTP Leader Clock for the network all other Dante devices act as a PTP Follower Clocks to the elected leader clock. Clock Synchronization In Standard Dante NetworksĪll Dante-enabled devices use the IEEE 1588 Precision Time Protocol (PTP) across the network to synchronize their local clocks to a leader clock, providing sample-accurate time alignment throughout the network.
