Eartec UPMON3 3-Person HUB Intercom System

Three-Person Wireless Intercom System for Hands-Free Team Communication
The Eartec UPMON3 is a complete wireless intercom system designed for small crews that need real-time voice coordination while remaining fully mobile and hands-free. This package includes one HUB Mini base station, three UltraPAK belt packs, and three low-profile Monarch dual-ear headsets—engineered for use in industrial, event, and production settings. Ideal for teams working on location, backstage, or across a facility, the UPMON3 system ensures seamless full duplex communication without tangled wires or push-to-talk delays.

Lightweight UltraPAK Belt Packs With Clear Audio and Easy Controls
The included UltraPAK remote belt packs operate on DECT protocol at 1.9 GHz, providing interference-free audio and extended range up to 1/4 mile. Each UltraPAK weighs just 2.5 ounces and includes user-friendly volume control, mute button, and LED status indicators. Designed for comfort and efficiency, these belt packs deliver stable, wireless performance in mobile or fixed setups, making them ideal for hands-on users such as camera operators, stagehands, or technical staff.

Rugged Monarch Headsets Built for Industrial Environments
Monarch headsets are designed with durable PBT polymer—commonly used in automotive bumpers—for maximum impact resistance. The dual-ear design enhances voice clarity while keeping users aware of their surroundings, and the slender back band ensures a low-profile fit that works for all users. Foam-padded ear cushions add comfort for extended wear during long productions or workdays. These headsets plug directly into UltraPAK belt packs and are optimized for clarity and comfort.

HUB Mini Base Station Offers Flexibility and Expansion
The HUB serves as the system’s central wireless relay and supports up to eight users in total, with one wired headset port and seven wireless slots. It offers a range of up to 1/4 mile using DECT technology and includes both a rechargeable lithium-polymer battery and AC wall plug for flexible operation. The HUB is compact and lightweight, and it can either be worn on the belt or placed on a flat surface, giving you deployment options based on your environment.

Rechargeable Battery System Keeps Your Team Running
Included in the UPMON3 system are four rechargeable batteries and an 8-port multi-charger. This ensures you always have enough power to keep your headsets and HUB online. The charger shows LED indicators for each bay—red when charging, green when fully charged—allowing you to monitor battery status at a glance. The quick 3-hour charge time and external battery design minimize downtime between shifts or events.

License-Free and Ready to Go Right Out of the Box
Operating on the 1.9 GHz band, the UPMON3 is FCC license-free and simple to set up. No configuration or frequency coordination is needed—just power on the HUB, connect the UltraPAKs, and your team is ready to communicate. This system is widely used in live event production, industrial safety teams, AV installations, and anywhere crystal-clear wireless audio is required with minimal setup time.
