Description

Clear-Com HLI-4W2 HelixNet Interface Module

The Clear-Com HLI-4W2 is a 4-wire interface module for the HMS-4X main station that enables 4-wire audio paths, such as matrix ports, cameras, and telephone circuits to interface with HelixNet intercom channels. It fits within one of the three rear panel interface slots of an HMS-4X main station. Two RJ-45 connectors on the module can be assigned via the main station menu.

HelixNet Main Stations accept both two-wire and four-wire optional interface modules, offering seamless connectivity to virtually all common two-wire and four-wire audio systems.

The Clear-Com HLI-4W2 Interface Module provides an easy way to interface common four-wire audio paths such as matrix ports, cameras, and telephone circuits with a HelixNet Main Station. Each of the two ports employs both transformer and electrical balancing to ensure incoming and outgoing audio paths are free of hum and noise.

Features

  • 4-wire interface module
  • Matrix port, camera, and telephone circuit assignment from HelixNet main station
  •  Two RJ-45 connectors per module
