Eartec UltraLITE Overview

This UltraLITE 4-Person Headset System from Eartec includes one UltraLITE Single-Ear Master headset, three UltraLITE Single-Ear Remote headsets, four rechargeable LiPo batteries, a ten-port charger, and a soft-side case.

The UltraLITE headsets have the transceiver built right inside the ear-cup, 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.

Are communications contained in the earpieces (no bleed in a quiet church environment)?
Asked by: Ole
The sound would be contained in the earpiece. The Eartec UltraLITE systems are made specifically for situations where the communication must be silent in the room, such as film and video shoots, or theater productions.

Is it possible to combine 2 sets to get 8 headset working together?
Asked by: Alvaro
No, it is not possible to combine two UL4S systems. Eartec's fully wireless UltraLITE headset system allows one master headset to be used with up to four remote headsets. If you require more than five headsets, you will want to use Eartec's HUB mini base station which allows use of up to eight wireless UltraLITE headsets and one wired headset. For a system with eight wireless headsets, the best option is the Eartec HUB8S UltraLITE 8-Person HUB Intercom System - USA (B&H # EAHUB8S) which includes eight wireless single-ear headsets and an additional wired headset (sold separately) can be added for use with the HUB base.

Hello! a year ago I bought a heatset 4 single set, I want to know if it is possible to add 2 more units to this set (to make a 6 heatset single system)
Asked by: RODRIGO
You need a hub to do that and you can't reuse the master headset so you would need the hub and three more wireless or 2 wireless and one wired to the hub.

I am considering these for a public school within a cafeteria like space. Part of our trouble is our PA system is limited to accepting devices. Do these have their own amp? Will they work with our system?
Asked by: Kristine
This won’t tie into anything. One of the headsets is also the base station. But they are perfect if you don’t need to tie into anything and just need to communicate.
