Extron Ships AES67-Based DMP 128 Series – And, Here’s Why This Matters…

Several competing Audio over IP protocols have emerged over the last several years and have been implemented in certain markets by various manufacturers. However, equipment using incompatible audio over IP protocols often needs to be part of a single system. Without an interoperability standard, designers and integrators have been forced to modify their equipment choices or abandon audio networking altogether, sacrificing the flexibility of an IP solution.

The AES67 standard provides interoperability between the predominant audio over IP protocols in use today. Developed by the Audio Engineering Society, published as an open standard in 2013, and most recently updated in 2015, AES67 is not an Audio over IP protocol by itself. Rather, it is an interoperability standard that acts as a translator between protocols. To take advantage of AES67 within a networked audio system, all system components must have implemented AES67 on top of their native protocols. Therefore, it is highly advisable to research what is implemented on the specific devices that will interconnect via IP within a design.

Extron has had Dante-enabled audio networking gear for years — as does many manufacturers. But, for system designs where required devices utilize an audio over IP protocol other than Dante, operating in AES67 mode provides interoperability with other AES67 capable devices on the network.

These Dante-enabled Extron products have additionally implemented AES67:
