6. Signal transport and storage in production environments
6.1 Two-channel cable transport
The exchange of audio data streams between production studio equipment is usually supported by two-channel links.
• Professional AES/EBU [IEC 60958-4]
The data stream consists of two channels, each coded linearly to a maximum of 24 bits. Three such links are needed to carry 5.1 without any reduction in bit rate.
Connectors can be either XLR 3-pin 110 Ohms or BNC 75 Ohms, hence the need for impedance adapters.
• Consumer S/PDIF (Sony/Philips Digital Interface) [IEC 60958-3], on coaxial cable with Cinch corrector and/or TDSLINK (Toshiba-Link) link on plastic fiber and EIAJ/JEITA corrector.
This link is used for linear stereo. For multichannel,...
