ProCo's Analog over Category boxes (AoC) allows users to run four channels of analog audio up to 100 Mtrs. Available with various connector combinations of XLR male, xls female, and Balanced 1/4" connectors.
The Boxes are extruded aluminum chassis and terminate with an individual Neutrik EtherCON connector. The AOC boxes allow for quick setup and longer runs with less signal degradation than conventional analog wire.
