• Separate Dante and AES67 flows can operate simultaneously. The total number of flows is determined by the maximum flow limit of the device.
Sending Audio from a Shure Device
All AES67 configuration is managed in Dante Controller software. For more information, refer to the Dante Controller user guide.
1. Open the Shure transmitting device in Dante Controller
2. Enable AES67
3. Reboot the Shure device.
4. Create AES67 flows according to the instructions in the Dante Controller user guide.
Receiving Audio from a Device Using a Different Audio Network Protocol
Third-party devices: When the hardware supports SAP, flows are identified in the routing software that the device uses. Otherwise, to receive an AES67 flow,
the AES67 session ID and IP address are required.
Shure devices: The transmitting device must support SAP. In Dante Controller, a transmit device ( appears as an IP address) can be routed like any other Dante
device.
Encryption
Audio is encrypted with the Advanced Encryption Standard ( AES -256), as specified by the US Government National Institute of Standards and Technology
(NIST) publication FIPS-197. Shure devices that support encryption require a passphrase to make a connection. Encryption is not supported with third-party
devices.
To activate encryption:
1. Open the Settings menu and select the General tab.
2. Select the Enable Encryption checkbox.
3. Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.
Important: For encryption to work:
• Encryption must be universally enabled or disabled on all connected Shure devices
• AES67 must be disabled in Dante Controller to turn encryption on or off. AES67 encryption is currently not supported.
Networking and Dante
Digital Audio Networking
Dantetm digital audio is carried over standard Ethernet and operates using standard Internet Protocols. Dante provides low latency, tight clock synchronization,
and high Quality-of-Service (QoS) to provide reliable audio transport to a variety of Dante devices. Dante audio can coexist safely on the same network as IT
and control data, or can be configured to use a dedicated network.
Switch Recommendations for Dante Networking
In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or router with the following features:
• Gigabit ports
• Quality of Service (QoS) with 4 queues
• Diffserv (DSCP) QoS, with strict priority
• Recommended: A managed switch to provide detailed information about the operation of each network link (port speed, error counters, bandwidth used)
Cable Requirements
Always use Cat5E cable or higher.
QoS (Quality of Service) Settings
QoS Settings
QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with heavy traffic. This feature is
available on most managed network switches. Although not required, assigning QoS settings is recommended.
Note: Coordinate changes with the network administrator to avoid disrupting service.
To assign QoS values, open the switch interface and use the following table to assign Dante™ -associated queue values.
• Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
• Use descending priority values for each remaining packet.
