AES/EBU, which stands for Audio Engineering Society/European Broadcasting Union, is a standard for digital audio interconnection. The AES/EBU digital interconnect is commonly used in professional audio applications to transmit high-quality digital audio signals between different audio devices.
The XLR connectors used in AES/EBU applications are designed to carry both the audio signal and provide a secure physical connection.
AES/EBU interconnects are typically constructed to meet specific 110Ohm impedance requirement
