Product Overview
The AoC Loom XLRf allows stable transmission of multiple audio or digital signals through one standard network cable (not included). The locking etherCON connection prevents accidental disconnection, while the colour-coded XLR outputs make channel identification quick and foolproof on stage or in the studio.
In addition to audio, the loom can also carry DMX or MIDI control data alongside phantom power—making it a flexible solution for live sound, broadcast, installations, conferences, and studio workflows.
