The Eartec HUBINTX HUB interface is a simple, affordable way to add full-duplex wireless headsets to RTS intercoms that use 3-Pin Female XLR. Each complete interface package includes a HUB mini base and a software-controlled interface. The interface connects the HUB-HD to the wall jack or rack-mounted power console. Signal level adjustments create a seamless audio link to any combination of up to 8 transceivers. Add up to eight wireless headsets to your RTS wired intercom system with this HUB Interface from Eartec. By adapting the HUB for use with the RTS system, this wireless-to-wired interface enables up to eight wireless users to roam freely and communicate in full duplex with the partyline-handsfree-just as if they were plugged in to the wired system by a cable. Push-button adjustments balance the signal levels creating a seamless audio link for production crews on the move.
