An XLR box, commonly known as an XLR patch bay or XLR splitter, is a device used in audio and video production to manage and route audio signals. It typically features multiple XLR input and output connections, allowing for easy organization and switching of microphone and instrument signals in studio or live sound setups. XLR boxes can also provide balanced connections, reducing noise and interference, and may offer additional features such as grounding switches and signal processing capabilities.
