UltraLITE Pro16 all-in-one wireless headsets can link up to 16 users in full duplex without a base station or hub. Designed with a lightning-fast microprocessor that provides two channels of simultaneous hands-free communication, the Pro16 allows separate groups to speak privately. Connect your entire crew in a full duplex conference with the simple touch of a button. The Pro16 talking pattern is easily modified in the field or expanded to accommodate your changing needs.

The Pro16 has been engineered with Active Frequency Hopping technology. This specialty wireless technique allows the headsets to monitor the surrounding environment and automatically switch channels whenever necessary to easily avoid interference. The operating range has been increased three-fold to over a 1/2 mile line of sight.

The UltraLITE headsets have the transceiver built right inside the earcup, eliminating headset wires and belt-worn radios. They provide two-way voice communication and the microphone arm can swivel 270°, allowing you to wear the mic on the left or right side. Raising the mic boom into the up position automatically mutes the microphone. 

A fortified mic assembly, featuring internal metal construction and stainless attachment hardware is now standard. The new deluxe earpad is extra wide, soft, and weather resistant. New, large-capacity lithium-ion polymer batteries provide an impressive run time of up to 10 hours.

A: We bought a system that came with 5 headsets and the hub and I bought a separate headset and added it! Great Systems!

Q: 2. Can I add two headsets to my set?

A: Yes you can have one more headset without any additional hardware needed. If you need more then 5 headsets add the hub in the link bellow and that will allow you to use up to 8 headsets at once. If in the future you need more then 8 simply add another hub by connecting the two it will give you room to add 8 more headsets. https://www.bhphotovideo.com/c/product/1269407-REG/eartec_hub_mini_duplex_transceiver_base.html

A: This system uses the POSITION of your microphone, as in:Position microphone UP = mutedPosition microphone down (front of mouth) = talk and continuously open until you move the mic back up again

Q: 5. the extrenal hub gives you more covered distance and better signal? im afraid of having interference on concerts with 2000 cellphones around...

A: The Eartec UL4S UltraLite system operates in the 1920 to 1930 MHz range. 900MHz, 1800MHz and 1900MHz frequencies are not used in the US with the exception of 1 band using 1900MHz. Most cell phones in the US operate in the 800MHZ frequency range. So the risk of any problems with cell phones is pretty much slim to none. Not to mention the protocols are different between cell phones and professional duplex intercom and IFB systems.

Q: 6. Is there a device to extend the signal when walls or balconies are in the way e.g. in an old theatre or in a stadium)?

A: I don't think you should have any problems as long as you are within the distance they are made for. In an open space they are good up to 1312'. Also they are not bluetooth they run in the 1920 to 1930 MHz range.

Q: 7. 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: 8. Can you get program audio into these?

A: No. You cant.

Q: 9. Can two of the headsets be used on their own without the hub? How do I make one a master and the other link to it without the hub? Instructions online show how to do this on a different model.

A: In his set up, the headset that connects to the hub with a cable is always the master headset. You would have to get a separate wireless master headset to use for a two-person set up, without a hub.

Q: 10. Can more remote headsets be added to the master or is 4 the max?

A: More headsets can be added.
