Connecting Yamaha Dante devices with AES67

3) One AES67-enabled Dante device will automatically be selected as the
Boundary clock, becoming the Dante Master.
C. An external word clock source is used, connected to a Dante device.
1) Enable “Sync to External” and “Preferred Master” for the Dante device
which is connected to the external clock.
2) Enable “Preferred Master” for the AES67-enabled Dante device which
should be the Boundary clock and the PTP v2 Master.
3) Disable “Preferred Master” and “Sync To External” for all other Dante
devices.
4) Assign a PTP v2 priority level of between 128 and 255 for all non-Dante
PTP v2 devices.
Of the three above solutions, A is probably the simplest to understand, though takes some
configuring for the other PTP v2 devices. B is easy to achieve. C is very difficult to
achieve in practice, and should be avoided if possible.
When solution B is used, make sure the Master Clock device is set to use the “Media
profile” (not the “Default profile”). Profiles are a set of parameters used to define the
network clock’s characteristics. In this case, the Media profile uses more frequent sync
checks than the default profile, so is better suited to high performance audio systems.
The Media profile settings are described in the AES67 standard. Dante devices do not
support the Default profile.
