The HMS-4X is a 1U digital partyline main station with 12 channels of full-duplex audio and program audio feed that can support up to 60 beltpacks on a single station (beltpacks sold separately). The user can listen in via the integrated speaker or headset and can talk via a headset mic or a push-to-talk microphone. Additionally, online configuration is available through the browser-based Core Configuration Manager (CCM) tool.

Linking

Up to three Main Stations may be linked using any combination of HLI-ET2 Ethernet or HLI-FBS Fiber modules.

Up to 3 LQ-R Series devices can be linked using the HLI-ET2 module. All linking is via IP over LAN/WAN connections.

Features

• Add up to 24 ports of audio inputs/outputs 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
• Up to 3 main stations and 3 LQ-R Series devices can be linked over LAN and WAN
