AES standard for digital audio engineering – High-resolution multi-channel audio interconnection (HRMAI)

Project scope: To specify a bi-directional, point-to-point connection for up to 48 channels of digital audio in a variety of formats. The link uses a single Category 5 (or better) structured-wiring data cable, and is designed for use in a studio environment. The system uses the 100Base-TX physical layer of Fast Ethernet (IEEE 802.3) to transfer framed audio data. Audio synchronisation is maintained by transmitting an audio clock signal in parallel with the audio data utilising available signal pairs on the cable.
