Application of RJ45-type connectors and quad twisted pair cable for audio Interconnections

For some years now, audio signals, both analog and digital, have been transmitted over hardware created for the Ethernet connection protocol, using quad twisted pair (QTP) cabling and “RJ45” connectors. This proposal calls for standardization of the “RJ45” connector pin-out, including channel order, pair color and polarities, and as these correspond to existing audio industry connectors including XLR, 25 pin DSUB and TRS. Other considerations include wiring recommendations, system caveats, and issues arising from operation in the presence of IP network cabling.

SC-05-02 has begun developing a draft standard on this topic.  All interested parties are encouraged to join SC-05-02 and participate.
