Q: 6. Our Church bought a 4 pack headset and we are wondering if we could buy another headset and somehow connect them together..?

A: Yes, if you are using a 4-person Eartec UltraLITE system that has one master headset and 3 remote headsets, you can add an additional remote headset and program it to work with the master headset. This type of system with one master headset can be used with up to 4 remote headsets for a maximum of 5 users. If you need to expand the system for more than 5 users, you can purchase the Eartec HUB Mini Duplex Transceiver Base (B&H # EAHUB) which will replace the master headset (the electronics in the master headset provide the same type of functions as the HUB), and you can use up to 8 wireless remote headsets and one wired headset that will connect directly to the HUB for a total of 9 users. Please contact us by phone or through live chat on the website if you would like further assistance with your wireless intercom system.

A: An "EU" version of the Eartec UL5S 5-Person Full-Duplex Wireless Intercom with 5 UltraLITE Single-Ear Headsets is recommend for use in Taiwan as opposed to the "US" version.
