Hollyland HL-2/4 Wire Converter for Intercom Systems

The Hollyland HL-2/4 Wire Converter bridges legacy 2-wire party-line and modern 4-wire matrix intercom infrastructures in broadcast trucks, studios, and live-event venues. Its industrial metal housing, flexible 12–36 VDC powering, and auto-null echo suppression deliver reliable, low-noise communication over long cable runs.

Distance compensation switches let you fine-tune for up to 656 ft (200 m) of cable, while front-panel gain trims and six-segment LED meters provide precise level control. Built-in static and voltage protection guards connected systems, and the compact enclosure integrates easily into existing racks or mobile kits.

This converter supports bi-directional audio and call signalling, making it ideal for integrating Clear-Com®, RTS®, Datavideo®, Syscom 1000T, and similar intercom models without additional hardware.

Key Features
