AES67 is a protocol for transmitting audio over a computer network. Unlike its proprietary contemporaries (eg Q-Lan, Dante), AES67 is an open standard and is thus implemented in many products.
Q-SYS offers the ability to use both Dante and/or AES67 to receive and transmit audio. However, AES67 does not require a license, which can make it appealing in many scenarios.
Q: Does AES67 support redundancy?
A: Unlike Q-LAN and Dante, AES67 does not support redundant topologies.
Q: How do I transmit AES67 from a Dante device?
A: This is done from the AES67 page in device view in Dante controller. Note that if that the page is missing, your device likely does not support AES67 at all. Please see this article from Audinate for more details - AES67 Config.
Q: How do I transmit AES67 from Q-SYS to a Dante device? / Dante controller shows "No audio data" when I receive a third party AES67 stream
A: The majority of Dante devices can only receive AES67 streams that have an address in the range configured in Dante controller (default 239.69.x.y). Please see this article from Dante for more details: AES67 Config
Q: Why can't I discover AES67 streams?
A: Most AES67 streams announce themselves over the network via Multicast (session announcement protocol). If you are having issues discovering streams, it is overwhelmingly likely that your network is not properly configured for multicast.
Q: Can you use AES67 to transmit audio between Q-Sys cores?
A: Absolutely. This may be a preferrable option to Q-Lan because unlike Q-Lan, you can transmit audio between cores on different firmware versions.
Q: How does AES67 work with Dante Domain Manager?
A: Audinate has excellent documentation covering this integration. See AES67 Interoperability | Dante and AES67 and SMPTE Domains.
