Eartec UltraLITE Interface to Wired Intercom — ClearCom / Metro (HUBINCC)

Add UltraLITE Wireless Headsets to Your ClearCom or Metro Theatre Intercom System

The Eartec UltraLITE HUB-INT interface bridges the UltraLITE HUB wireless system with 2-wire wired intercoms — bringing full-duplex wireless headsets to permanently installed party line systems without floor cables or major infrastructure changes.

This version (HUBINCC) is designed for ClearCom and Metro Theatre intercom systems, which operate at a higher intercom voltage (30V DC). For Tecpro and Telex Audiocom systems (24V DC), order the HUBINTX instead.

The interface draws its power directly from the intercom circuit. On power-up, a software-controlled circuit initiates the signal balancing automatically — but this also means the interface loses its settings if power is interrupted.

Important: The interface must not be connected to the HUB when it is powered up. Connect the interface to the intercom first, allow it to initialise, then connect the HUB.

Showcomms supplies a setup crib sheet with every HUBINCC order to guide you through the initialisation sequence.
