AES3 - A digital audio standard defined by the Audio Engineering Society. The standard specifies several basic physical interconnections between devices:
- Balanced – 3-conductor, 110 ohm cabling with an XLR connector, typically referred to as “AES/EBU audio.”
- Unbalanced – 2-conductor, 75 ohm coaxial cable with an RCA connector, typically used in consumer audio applications. In many consumer products such as DVD players and AV receivers, this is often referred to as a “digital coaxial” connection type.
- AES-3id – A professional version of the 2-conductor 75 ohm coaxial cable terminated with a BNC connector. AES3 unbalanced and AES-3id audio can be switched or routed using a video switcher with a minimum of 150 MHz (-3 dB, fully loaded) video bandwidth.
