The HRM-4X is a 4-channel 1RU digital partyline headset and speaker Remote Station that connects to HelixNet HMS-4X Main Stations and other HelixNet user stations over a single shielded twisted-pair cable. The HRM-4X can be locally powered via an external power supply or third party Power-over-Ethernet (PoE) power source.
