Eartec UPMX4GD2 2-Person Full Duplex Wireless Intercom

Hands-Free Wireless Communication System for Two-Person Crews
The Eartec UPMX4GD2 is a compact, full duplex intercom system designed for two users who need uninterrupted, hands-free communication in active environments. Featuring the Eartec HUB Mini Base Station, two UltraPAK beltpack transceivers, and two Max 4G Double Headsets, this system allows simultaneous talk across a job site without delays, push-to-talk limitations, or tangled wires. With a range of up to 1/4 mile and no FCC licensing required, it's ideal for AV teams, sports production, warehouse operations, or construction.

Comfortable and Durable Max 4G Double Headsets
The included Max 4G double-ear headsets are purpose-built for clarity and comfort in high-noise environments. Their over-the-head design and thick foam padding provide a secure fit and noise isolation during long shifts. A rotatable boom arm features built-in AutoMute technology—simply rotate the mic upward to instantly mute your voice. These headsets are rugged, field-tested, and ready for day-to-day use in demanding job sites.

Compact and Lightweight UltraPAK Beltpacks
The UltraPAK transceivers weigh just 2.5 ounces and clip easily to belts or clothing, offering minimal interference with workflow. Each unit includes volume control, a sealed mic mute button with LED status, and reliable audio transmission through DECT 1.9 GHz wireless. Perfect for professionals who require portable communication without sacrificing performance.

Battery Power That Keeps You Going
This system includes three rechargeable lithium batteries—two for the UltraPAKs and one for the HUB. Each battery provides approximately 6 hours of runtime and charges in the included 8-port multi-charger. The batteries are field-replaceable and externally charged, allowing for hot swapping to ensure continuous operation throughout the day.

HUB Mini Base Station Expands Coverage and Team Size
At the center of the system is the HUB, a portable mini base station that supports up to eight users in full duplex. With dual-channel operation and optional AC or battery power, it offers reliable signal relay even on large job sites. The HUB can be worn on a belt or placed on a flat surface, giving you flexible deployment depending on your team’s needs.

Protected and Organized for On-the-Go Use
Everything fits neatly into the included soft-sided case made from weather-resistant nylon. Molded compartments keep each component secure and organized during transport, while a padded handle ensures comfortable carry. It’s a practical addition for crews working on location or shifting between multiple venues.
