Open projects

AES72 – Application of RJ45-type connectors and quad twisted-pair cable for audio interconnections
Anthony has contacted several manufacturers of RJ cable adaptor products informing them of AES72 and encouraging adoption. He does not yet know which manufacturers will agree to label their products in accordance with the standard. Anthony reviewed several of the products currently on the market. He then reviewed the basics of the standard and some of the development history. Anthony will be presenting a webinar on the standard and its applications in September. He expects to include real-time demonstrations in the presentation.
