Clear-Com HMS-4X HelixNet Main Station

HMS-4X Main Station Highlights:

• Four independent intercom channels and power for Beltpacks transmitted over a shielded twisted-pair (mic cable or CAT-5 cable).
• No rewiring required for communicating on more than one partyline channel or for adding or changing channel assignment.
• Single cable operation to deliver cost savings, cable reductions, and time savings during setup and configuration. Fewer cables means touring crews have more space and less weight to transport.
• No hum or electro-magnetic interference thanks to an all-digital system architecture.
• Works with existing partyline products and cables.
• Clear-Com Sound: Legendary contoured audio frequency response for maximum intelligibility and exceptional sound quality.
• Plug-and-go system with hardware auto-discovery allows any connected beltpack or user device to be immediately recognized.
• Seamless connectivity to existing analog intercom systems and audio devices using optional 2-wire and 4-wire interface modules.
• Easy-to-navigate menu provides quick access to system settings and configuration, for fast and painless set up.
• High-resolution, large format OLED displays provide up to 10 characters of user-defined labels.
