You have a professional 16-channel audio snake cable system (also known as a multicore cable or audio link). These systems are designed to bundle multiple audio signals—typically from microphones or instruments—into a single, organized cable to run long distances between a stage and a mixing console.
* Key Components*
• Stage Box: The black metal box features 20 total XLR ports. It is often configured as 16 inputs (for microphones/instruments) and 4 returns (labeled A, B, C, D for monitors or speakers).
• Multicore Cable: The thick, coiled cable contains individually shielded pairs of copper conductors to ensure clear sound and minimal signal interference.
• Fan-Out (Tails): The bundle of numbered XLR connectors at the end of the cable connects directly into the mixing board.
