Clear-com HRM-4X 4-Channel Remote Station

Clear-com HRM-4X 4-Channel Remote Station

Clear-com HelixNet HRM-4X remote station is a 1RU 4-channel intercom user station with utility connections for Program Audio input and Stage Announce output, hosted by Arcadia® Central Station or HelixNet HMS-4X main station.

User Station

The innovative front panel user station provides four keysets assignable to any intercom channel. The user station is provisioned with a headset connection, gooseneck mic connector and a loudspeaker in addition to All Call, Stage Announce, Remote Mic Kill and Program Audio level controls.

Expansion mode allows up to six HRM (or HMS-4X in non-Arcadia systems**) networked user stations to be combined, for a unified user station with up to 24 channels.

Local and Central Management Options

HRM-4X can be added to an Arcadia or HelixNet system host without central configuration or interruption. Front panel keysets form unique waterfall menusallowing tactile device configuration and channel assignments.

Roles can be created and applied to one or multiple HRM-4X remotely or locally. Roles can be edited locally or centrally managed from the Core Configuration
Manager (CCM*).

Connectivity and Power Options

HRM-4X connects to Arcadia Central Station or HelixNet HMS-4X main station with HLI-ET2 Ethernet module over network. Power can be supplied to the HRM-4X locally with a supplied power supply or Power over Ethernet (PoE) from 3rd party devices.

Alternatively, HRM-4X can connect to HelixNet HMS-4X main stations over XLR Powerline with power or locally powered.

*CCM and Endpoint network connection to HMS-4X requires HLI-ET2
**HMS-4X is not used in Arcadia hosted HelixNet Systems
***XLR Powerline connection is not available for Arcadia. Contact Clear-Com for further information.
