The Clear-Com HLI-2W2 is a professional interface module designed to bridge Clear-Com's digital HelixNet party-line intercom systems with traditional 2-wire analog party-line systems. This module enables seamless communication between users on a modern HelixNet network and those using legacy 2-wire beltpacks or station equipment, allowing organizations to integrate and extend their existing intercom infrastructure without requiring a full system replacement. The HLI-2W2 provides two independent channels, allowing it to interface with two separate 2-wire party lines or to provide separate talk and listen paths on a single line. It is typically mounted within a HelixNet main station or a compatible interface enclosure, drawing power from the host system and requiring no external power supply.

The module ensures high-quality audio conversion with appropriate level matching and noise isolation, maintaining clear and reliable communication across the hybrid digital-analog environment. It includes features such as ground lift switches to eliminate ground loop hum and level controls to balance audio between the systems. By providing this critical interoperability, the HLI-2W2 protects investments in legacy analog equipment while enabling users to take advantage of the advanced features, superior audio quality, and scalability of the HelixNet digital platform. It is an essential tool for broadcast facilities, live event production companies, and theaters undergoing phased technology upgrades.

As a key integration component, the Clear-Com HLI-2W2 facilitates a smooth transition to digital intercom networks. Its robust design and transparent operation make it a reliable solution for creating unified communication systems that serve both new and existing users across different technology generations.
