AES67 Overview

AES67 is a networked audio transport similar to Dante, AVB, and CobraNet.  It is a standard to enable high performance audio-over-IP streaming interoperability between the various IP based audio networking products currently available, based on existing standards such as Dante.

The BSS Soundweb London BLU-806DA, BLU-326DA and BLU-DA are capable of sending and receiving audio over AES67.  The BLU-806DA, BLU-326DA and BLU-DA running firmware version 86.4.1 or later are also capable of sending and receiving audio over AES67.  AES67 is a property of these devices and can be disabled if required.

AES67 operates at sample rates of 48kHz only.  For venues running at a sample rate of 96kHz, AES67 must first be disabled before changing the sample rate.

The devices will be running London/Dante software version 1.2.2 or higher.  Expand the Device tree in Audio Architect to see the firmware version.

Devices running this version of firmware will enable the AES67 tab in Dante Controller Device View.

AES67 is an option within Dante. Although Dante routing can be configured either via the Matrix Router or via Dante controller, AES67 Multicast flows can only be configured using Dante Controller.

Any combination of Dante and AES67 can be transmitted / received simultaneously within a device e.g.

·       Transmit Dante, receive Dante, receive AES67

·       Transmit AES67, receive Dante receive AES67

·       Transmit Dante, transmit AES67, receive Dante, receive AES67

Devices in AES67 mode are able to transmit and receive AES67 multicast flows to / from non-Dante AES67-enabled devices. Between Dante devices, Dante's native audio transport protocol is used instead (even when AES67 is enabled for both devices).  The routing in Dante Controller will display AES67 channels only for non-Dante devices, Dante devices will display Dante channels even in AES67 enabled devices.

Each BSS Soundweb London AES67 enabled device is capable of sending 64 channels and receiving 64 channels of audio over AES67 at 48kHz. Sample rate is restricted to 48kHz only over AES67. 

Refer to Dante Overview for details on setting up a Dante network.
