XLR Connectors
These are the most common professional audio connectors. They almost always carry
a balanced signal. Many cables use an XLR connector on one end and a 1/4" TRS
connector on the other. The signal may be microphone level (when using a
microphone) or +4 dBu/dBm (professional) line level.
