A: The Eartec UL5S 5-Person Full-Duplex Wireless Intercom with 5 UltraLITE Single-Ear Headsets includes one wireless master headset and four wireless remote headsets. The master headset can be used with up to four remote headsets, so this system is not expandable unless you add the Eartec HUB Mini Duplex Transceiver Base for 1 Plug-In & up to 8 Wireless UltraLITE Headsets (B&H # EAHUB). The HUB contains the same electronics that are used in the master headset, so the HUB will be used instead of the master headset if you expand the system. It will allow you to use up to eight wireless remote headsets and one wired headset. The HUB can operate with a battery so it can be worn like a wireless beltpack together with the wired headset. You can also further expand the system by linking two HUBs to accommodate up to 16 wireless remote headsets.
