The Call for Comment on DRAFT AES72-xxxx, "AES standard on interconnections - Application of RJ45-type connectors and quad twisted pair cable for audio interconnections" was published 2019-02-15.
This standard documents 8P8C (RJ45) pin-outs commonly used in analog and digital professional audio applications to carry four links, including channel/link order, signal polarity and phantom power compatibility. Type numbers are assigned to these variations, allowing manufacturers to easily specify which wiring standard is used in a particular piece of equipment. Users may use these type numbers to assess compatibility of disparate equipment in a given application. This standard also documents practical application details of interest to users of this technology. Conformance with this standard will identify mutually compatible devices, enabling users to avoid problems when employing equipment from multiple manufacturers.
