HelixNet Main Stations accept linking as well as two-wire and four-wire optional interface modules, offering seamless connectivity to LAN and virtually all common two-wire and four-wire audio systems.
The 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 employ both transformer and electrical balancing to ensure incoming and outgoing audio paths are free of hum and noise.
