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.
Designing a seamless interface between analog two-wire and digital systems is no simple feat, yet Clear-Com has done just that. The HLI-2W2 Interface Module enables two-channels of Clear-Com or RTS intercom to transparently interface with digital HelixNet intercom channels. This two-wire module preserves the wideband two-wire frequency response, is conveniently packaged in a rugged, pluggable module, and is easily assignable to any of the HelixNet Main Station intercom channels
