Eartec HUB INT Interface Module

An installed party line is expensive to rip out and cabling a roaming position into it is worse. The HUB INT interface is the cheap way around both: a software-controlled circuit plugs into the wired line, a HUB mini base repeater plugs into the interface, and up to eight wireless headsets join the existing system. Dial adjustments on the module itself balance the signal levels between the wired line and the HUB, so the audio link comes up level instead of hot on one side.

Order the module that matches the intercom you already own. Once linked, the HUB adds full duplex for up to eight wireless users over a 300-yard range, on two channels, with headsets split across channels A and B or joined into one team at the push of a button. It runs on DECT and needs no FCC licensing. The HUB mini base is purchased separately.
