## Overview

The Eartec UL422 UltraLITE is a professional-grade wireless intercom system featuring full duplex communication for up to 4 simultaneous users, expandable to 5. Operating on a 1.9 GHz frequency, it delivers up to 1000 ft line-of-sight range and 6 hours of talk time per charge. Its innovative design integrates all electronics within the ear cups, eliminating belt packs for maximum comfort. Equipped with noise-cancelling microphones and a pivoting boom, it ensures clear communication in high-noise environments, making it ideal for video production, construction, and other demanding professional settings.

## Description

UltraLITE are breakthrough full duplex wireless headsets that provide hands-free, two-way voice communications. At the heart of these systems is a specialty "Master" headset that relays the digital signals generated by up to three "emote" units. The resulting open line talking pattern allows up to 4 people to talk simultaneously without pushing buttons. To formulate your standard UltraLITE system select any combination of Double or Single ear headsets - up to 4 units. UltraLITE Double headsets allow users to remain in constant full duplex voice contact even while on the move. What sets them apart from most other wireless headsets is that they operate without belt pack transceivers. All electronics, even the battery, are installed right inside the ear cups. The UltraLITE Double includes deluxe padding and fully adjustable noise cancelling microphone to insure effective voice communication even in high noise environments.
