Q: 3. if I use 4 entire sets of this unit in a common space for 4 different user groups. will they work flawless without any crosstalk or interference.? also can I connect 2 or more Hubs together to get a larger common user group?

A: No, it is not possible to use four separate Eartec systems simultaneously in the same general open space because they would interfere with each other. However, the signal is not able to travel through walls or floors, so if the systems are placed far enough away from each other with walls or floors between each system, they could be used at the same time. But in one open space multiple systems cannot be used at the same time. It is possible to link two Eartec Hubs together to create a larger single wireless intercom system that will accommodate up to 16 users.

Q: 4. Can you integrate with a Clear-Com system or is this a standalone system?
