The Hub with UltraLite Serie - Single Headsets

Expanded UltraLITE wireless systems for larger crews / HUB full duplex wireless headset intercom
UltraLITE self-contained headsets provide professional full duplex wireless communication literally right “Out of The Box”. To operate simply turn the headsets “ON” and talk it’s that simple. All electronics, including rechargeable lithium battery, are installed right inside the ear cup.
The HUB is a revolutionary mini base station that expands the capacity of UltraLITE linking up to 8 wireless headsets allowing larger production crews to communicate hands free.
Weighing only 9 oz. the HUB can either be placed strategically “on location” or belt worn. When clipped comfortably to the users waste it moves seamlessly so your crew can remain in constant full duplex voice contact.
Two HUBs can be interlinked doubling the talking pattern to 16. An added benefit is that HUB transceivers include an accessory jack so that with addition of a plug-in headset capacity is expanded to a crew of nine all communicating in full duplex.
Both HUB and UltraLITE utilize the same Lithium Polymer batteries (included), that charge externally and are field replaceable. This allows you to keep spare batteries on hand extending the run time of your system.
The included multi-port charger features positive LED indicators. When the batteries reach full charge the corresponding LED turns from red to green indicating that the battery is ready to go.
If you need to add full duplex wireless to an existing, permanently installed wired system in an auditorium, church, or production studio the HUB with UltraLITE has you covered. The HUB interface is a software controlled module that plugs into a wall jack replacing a wired amplifier and allows up to 8 roaming wireless users to communicate with the wired system in full duplex just as if connected by a floor cable. (see HUB Interface page to learn more).
Since UltraLITE are field programmable you can always modify your system adding components at any time expanding the talking pattern as your needs grow.
Select from the standard HUB w/ UltraLITE packages or contact EARTEC for help designing a customized full duplex system specifically for your production staff.
