Introduction

This document provides an overview of Glensound Dante products and their interoperability with AES67 and other network audio protocols including instructions for configuring Dante devices to work with AES67.

AES67 Mode


AES67 Information

AES67 is an audio over IP standard compatible with Dante. Glensound Dante devices support AES67 mode which allows the device to work with different audio IP standards on the same network.


A Dante device can support any mix of Dante and AES67 flows up to the maximum supported on the device.


AES67 traits with Dante

AES67 flows can only be generated with the following rules:


•Multicast Only

• Non redundant

• Destination address in range 239.nnn.0.0 to 239.nnn.255.255 (239.nnn/16), port 5004

• 48kHz sampling rate

• 24 bit linear (L24) encoding

• 1 msec packet time

• Up to 8 channels per stream (dependant on dante device)


Received AES67 flows have the following rules:


• Multicast Only

• Non redundant

• Destination address in range 239.nnn.0.0 to 239.nnn.255.255 (239.nnn/16), port 5004. Must match destination address range.

• 48kHz sampling rate

• L16 or L24 encoding

• 125usec, 250usec, 333usec, 1 msec packet time

• Up to 8 channels per stream (dependant on dante device)


The saved configuration will persist if the device reboots.


AES67 Transmit flows created on a Dante device will be advertised via the Session Announcement Protocol (SAP). The announcement interval is 30 seconds.


AES67 Transmit flows are represented as virtual devices in Dante Controller, allowing configuration of AES67 Rx flows by clicking channel intersections in grid view, or drag and drop in Device View.


The receive latency for AES67 Rx flows is set to 2 Ms, this setting is not affected by changing the latency setting in Dante Controller.


Turning on AES67 mode for generic operation

Ensure you have the latest firmware for you device from Glensound. Always check www.glensound.com and the product page to check if your device is up to date. To see current version, check the Dante controller device view tab ‘Status’.


Next, locate the ‘AES67 Config’ tab. Choose enable and reboot the device.


After the reboot go back to the AES67 tab and set the multicast prefix address to one that is suitable for your newtork. This might change if you wish to interface with various other AES67 compatable devices which will be explored later in the document.
