Clear-Com HMS-4X 4-Channel 1RU Digital Main Station

Clear-Com HMS-4X 4-Channel 1RU Digital Main Station

Seamless LinkingLink main stations together using LAN, fiber, 2-wire or 4-wire without the need for active splitter devices. Once linked, auto-discovery detects and configures linked devices so that any beltpack has access to active intercom channels.

Configuration Made SimpleThe free, browser-based Core Configuration Manager (CCM) tool provides the same functionality as the main station menus and is supported by all major browsers on MAC, PC and tablet platforms.

Easily Expand SystemWith an optional channel expansion license, a single main stations channel capacity increases to 24 available channels. Add up to 24 ports per main station by connecting to LQ Series devices.

Single Cable OperationAll networked intercom channels and power for beltpacks or a combination of user devices can be transmitted over a single shielded twisted-pair cable (mic cable for powerline, CAT5/6 for Power-over-Ethernet).
