Clear-Com HRM-4X HelixNet Remote Station

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.

New in Version 4.0 (Available Now):

Add up to 24 ports of audio I/O per Main Station by connecting to LQ Series
Quickly connect Agent-IC mobile clients with existing HelixNet users via connected LQ Series devices
Binaural listening on HXII-BP-X5 beltpacks
SIP/VoIP calling from HelixNEt via LQ Series
