Connecting Dante devices with other AES67 devices
AES67 is a published standard which defines interoperability guidelines for high performance professional digital IP networking. AES67 provides the means for exchanging audio streams between areas with different networking solutions or technologies already in place, such as Dante, Ravenna, Q-LAN, Livewire, and WheatNet.
Yamaha also has started to successively update Dante products to support the AES67 standard beginning with the CL/QL series consoles and R series I/O racks. However, please understand that AES67 is a transport option as part of Dante but will not be a replacement of Dante. This is because Dante is a complete audio networking solution, including control & monitoring software, network redundancy, and automatic device discovery, while AES67 has limited functionality to achieve wider interoperability as
This document describes general instructions to connect Yamaha Dante devices with 3rd party non-Dante AES67 devices. For details on the 3rd-party device setup, please refer to the documents each manufacturer provides as well.
Dante Controller v220.127.116.11 and later supports the AES67-enabled Dante devices, but as of January 2017, the following requirements and limitations are applied to the use of AES67 with Dante.
SAP (Session Announcement Protocol) must be supported.
This is one of four device discovery methods referenced in the AES67 standard.
Check if the transmitting non-Dante AES67 device supports SAP. Otherwise Dante Controller cannot discover the audio flows coming from the device. Dante devices support SAP if their AES67 mode is enabled. Even if the non-Dante AES67 device does not directly support SAP, the vendor may have a software conversion tool available, providing wider compatibility, such as ALC NetworX RAV2SAP.
Multicast flow only (unicast is not supported yet).
Up to 8 channels per flow.
Multicast IP addresses must be in the range of 18.104.22.168 - 22.214.171.124/16.
In addition, the same network address range must be specified for other AES67 devices transmitting to Dante devices.
48 kHz sampling rate only.
The Dante audio flows from/to the device will also be limited to 48 kHz if the device is engaged in AES67 mode.
24 bit (L24) only for transmission and reception.
2 milliseconds fixed latency for reception.
Primary network only (redundant network is not defined within the AES67 standard).
100 Mbps or slower connections are not supported.
In addition, please be aware of the following notes due to known issues.
Initialize the Dante module before the AES67 mode is enabled.
Do not change the TX multicast address prefix (default 239.69).
Do not change the bit depth (default 24 bit) from Dante Controller or the console after
enabling the AES67 mode. Rebooting the device or Dante module with the change could reset the multicast addresses if using a different multicast address prefix other than default 239.69, which would cause audio interruption.
Do not change the multicast addresses and labels of non-Dante AES67 transmission flows patched to Dante AES67 devices. The change could cause audio interruption.
If the device labels are changed, reboot the Dante module. The AES67 transmission flow labels will not be updated until after the reboot.
