Project AES-X213 initiation

[page updated 2012-11-07]

This project was proposed by Marc Brunke. It was approved under our rules by Subcommittee SC-02 and assigned to the SC-02-02 Working Group on Digital Input/Output Interfacing.

TITLE AES-X213, MADI over twisted-pair cabling
SCOPE To add twisted pair connectivity to AES10 in addition to the current connectivity options.
RATIONALE A twisted-pair interconnection should lead to further simplification of multichannel audio connectivity and significant cost reductions.
  1. Interface cost reduction allowing for use in low and high channel capacity applications.
  2. Allows use of commonly available Category 5 (or better) cabling infrastructures.
  3. Smaller footprint for device connectors, allowing for high density connectivity.
  4. Easier implementation, as the most of the coding is done by a cost effective and readily available Ethernet PHY.
  5. Galvanic isolation for copper based AES10 interfaces.
  6. Guarantees immunity from obsolete, boutique and expensive components
  7. Optionally allows for standardized control using 10/100MB Ethernet on the same cable/connector as MADI.
  8. Optionally allows for devices to be remote power over the interface using PoE phantom power.

WHO BENEFITS? Professional audio users who would have greater range of connectivity options.
Developers of audio systems who could add connectivity features at lower cost.
WHY AES? This would be a natural extension of the existing AES10 MADI standard
