Advanced Settings

Use the Advanced Settings page to set the clocking mode for the domain, and manually configure domain clocking.

Clocking Mode

Three domain clocking modes are supported:

  • Default

    In default mode, the domain uses the standard Dante PTP clocking solution as described above.

  • AES67

    In AES67 mode, the domain is configured for AES67 clocking, enabling audio interoperability between Dante devices and non-Dante AES67 devices.

  • SMPTE

    In SMPTE mode, the domain is configured for SMPTE ST 2110-30 clocking, enabling audio interoperability between Dante devices and non-Dante SMPTE devices.

See AES67 and SMPTE Domains for more information.

PTP Configuration

Set the PTP Configuration to 'Custom' to enable PTP V2 clocking, specify the PTP V2 domain number, and specify the default PTP V2 priorities for all supporting devices in the domain (or shared audio group).

This feature enables you to configure the domain so that a non-Dante clocking device (for example, a GPS-enabled device) can win the clock election, and thus become grand leader clock for the domain.

PTP V2 priorities can also be specified at device level via the 'Customize Clocking' feature. Device-level priorities override domain-level priorities.

Note:  Custom PTP configuration is supported by devices at v4.2 firmware or above.

Note:  With Custom PTP Configuration enabled, the Dante Controller 'Preferred Leader' setting is unavailable for devices enrolled in the domain.

Note:  The PTP V2 domain number cannot be specified for AES67 domains.

Domain Clocking

Manual clocking configuration allows you to selectively nominate unicast clocks for the domain. Suitable devices are those that are unlikely to be removed from the network or powered down. Where possible you should nominate two devices.

Note:  As a rule of thumb, the more powerful Dante platforms provide slightly better clocks - for example, a Brooklyn II based device should be preferred over an Ultimo based device.

To configure clocking for a domain manually:

  1. In the Domains page, select the relevant domain.
  2. In the Domain Details panel, click Advanced Settings.
  3. For each subnet, enable one or two devices to act as unicast clocks.

Note:  It is common for devices to share the roles of subnet leader and unicast clocking (boundary clock). See Synchronous Clocking for more information.

Assign Zone

Enables subnets in a domain to be independently clocked by an external clock source (for example, GPS).

See About Zones for more information.

Note:  The Assign Zone button is displayed when two or more devices in a domain reside in different subnets.

Customize Clocking

Click Customize to enable PTP Preferred Leader and PTP sync External for the device, and to toggle PTP v1 delay requests between unicast and multicast. See the Dante Controller user guide for more information about these device features.

For SMPTE domains, you can also use Customize Clocking to specify the PTP V2 priorities and the RTP prefix for RTP-enabled devices.

For domains with a Custom PTP configuration, you can use Customize Clocking to specify the PTP V2 priorities for devices.

Shared Audio

Clocking settings can cover multiple domains if you have configured audio sharing between domains.
