Clear-Com HLI-2W2 HelixNet 2-Wire Interface Module

In combination with a HelixNet Main station, the HLI-2W2 interface module allows seamless connectivity to almost all common two-wire audio systems. Plug the HLI-2W2 into one of the rear panel slots of the main station, (sold separately) and a pair of 3-pin XLR connectors on the HLI-2W2 send the audio to connected intercom lines such as Clear-Com or RTS, assignments can be made via the main station menu. Requires external partyline power source.
