The Eartec HUB is a wearable mini-Base that expands the capacity of UltraLITE wireless headsets for larger crews that need to communicate and work with their hands. This compact transceiver weighs only 9 oz and can either be placed in a strategic position when "on location" or can be belt worn. When clipped comfortably to the user's waist it moves seamlessly with your group allowing UltraLITE headsets to remain connected in full duplex. Each HUB mini-base can accommodate up to 8 UltraLITE remote headsets and 1 wired headset. Please note once you have added a HUB and one of the 3 wired headsets to your UltraLite system, the HUB becomes the "MAIN", all other communication can only be transmitted by using "REMOTES".
