Balanced Inputs/Outputs

Balanced Inputs/Outputs: A protocol for connecting analog audio devices using impedance-balanced cables. This protocol is usually associated with professional-level audio equipment and allows for longer cable lengths as well as reducing the addition of external noise to the signal. Balanced cables have either XLR or TRS plugs. Professional-level digitization will usually involve balanced outputs on the analog playback device and balanced inputs on the analog to digital converter. A balanced signal can be converted to an unbalanced signal through the use of a DI unit or a transformer. A simple XLR to ¼” adapter will not suffice. [ Audio Glossary ] [ Video Glossary ]
