    HMS-4X - Overview

    The ClearCom HMS-4X HelixNet main station is a combination of a system master and intercom user station with XLR Powerline connections to the user stations. HMS-4X hosts up to three HLI interface modules for external connectivity including Ethernet and Fiber.

    The HMS-4X manages all endpoint connections and Ethernet routing of incoming audio to all listening user stations and interfaces where the audio is locally mixed. HelixNet's 12 channels of partyline intercom and Program Audio are available at any HelixNet user station or interface port regardless of where they connect to the system. The optional license expands the HMS-4X to support 24 channels.

    HMS-4X features two XLR Powerlines each capable of supporting up to 10 user stations. Powerline allows digital connection using standard XLR cables and supports various cabling topologies and passive splitting, like analog partyline cabling. HMS-4X also supports endpoint connectivity over mix of Powerline and Ethernet with the optional HLI-ET2 Ethernet module. HelixNet supports up to 64 endpoints, user stations or interface ports. User stations may be added and removed dynamically without configuration and assigned to any channel without restrictions.

    HMS-4X hosts firmware for endpoints and automatically matches versions upon endpoint connection. Linking Up to five additional HMS-4X main stations can be linked to the master HMS-4X over Ethernet networks or fiber for a total of six linked HMS-4X. Link groups of multiple HMS-4X seamlessly form a distributed HelixNet system, allowing local connectivity using HLI interface modules and XLR Powerlines to user stations.

    Please Note! This item is just one component of a larger system. Please refer to the diagrams for ideas and recommendations on how to build a Clear-Com intercom system to suit your needs.
