Product Description
The AoC Loom XLRm enables the stable transmission of up to four balanced analogue audio signals—or eight AES3 digital channels—through a single standard Ethernet cable (not included). Its locking etherCON connector prevents accidental unplugging, ensuring reliable performance in demanding live and installed setups.
Beyond audio, the loom can also carry DMX or MIDI control signals, as well as 48-volt phantom power, all over the same Cat cable. This makes it a highly flexible solution for live sound, broadcast, studio recording, press conferences, theatres, and AV installations where clean cabling and fast deployment are essential.
Built with premium Neutrik connectors, a rugged aluminium-steel housing, and durable mesh cabling, the AoC Loom XLRm is engineered for long-term reliability. Its compact, professional design not only withstands tough environments but also keeps stage and rack layouts clean and organised.
