Impedance Matching Transformers
Used to convert 110Ω AES/EBU digital audio signals to 75Ω signals and 75Ω signals to 110Ω
Allows for long distance transmission of AES/EBU digital audio over standard 75Ω coaxial lines
Can also be used to connect AES/EBU digital audio signals to high-definition, broadcast quality video patchbays for secure and lossless patching
