16 BASS V-AMP / BASS V-AMP PRO User Manual 8.5 AES/EBU and S/PDIF standards In general, there are two different standards when the subject is digital signal processing. AES/EBU is the professional, balanced connection with XLR jack connectors. This interface is based on two identical protocols published in November 1985 by the European Broadcast Union (EBU Tech. 3250-E) and in December 1985 by the Audio Engineering Society (AES3-1985). Sony and Philips oriented themselves around this standard and developed an additional interface with unbalanced signal routing and several important differences that primarily have to do with allocating channel status bits. This standard, named after the two com-panies (S/PDIF = Sony/Philips Digital Interface) uses either cinch jacks or a digital connection with optical cables. It is relevant mostly because of the attempt to introduce copy protection embedded in the IEC 958 norm. This norm describes both the re-worked AES/EBU interface that has been modified to work with the S/PDIF format and described as IEC 958 Typ I (Professional). The formal description of the S/PDIF interface is IEC 958 Typ II (Consumer). 9.
