EC-1 AES/EBU Interface, Appendix E E- 4 EC-1 M ANUAL 1.00 A BOUT THE EC-1 The EC-1 is an optional AES/EBU protocol expansion card designed exclusively for the M20. It provides 8 simultaneous channels of AES/EBU digital audio inputs and outputs via eight XLR type jacks (four input channel pairs and four output channel pairs).
