Eartec UPMON6 6-Person Intercom System

Six-Person Wireless Intercom System for Full Duplex Communication on the Move
The Eartec UPMON6 is a professional wireless intercom system designed for six users who need clear, hands-free, full duplex communication while staying mobile. It includes one HUB Mini base station, six UltraPAK belt-worn transceivers, six Monarch midweight dual-ear headsets, six rechargeable lithium batteries, an 8-port charger, and a rugged soft-sided carry case. Ideal for stage crews, industrial teams, and video production units, this kit supports simultaneous talk for all users within a 300-yard range using license-free DECT technology.

UltraPAK Belt Packs Combine Compact Design with Durable Performance
UltraPAK transceivers are some of the smallest full duplex belt packs available—each unit weighs only 2.5 oz. Designed with a low-profile housing and equipped with a military-style clothing clip, these compact radios are easy to wear during extended workdays. They include a sealed silicone mute button with LED indicator and a five-step volume control interface. The headset connection uses a reliable 2-pin port that ensures a secure and consistent audio link even in challenging environments.

Monarch Headsets Are Rugged, Padded, and Built for All-Day Wear
Each system includes six dual-ear Monarch headsets constructed with tough PBT polymer—the same material found in automotive bumpers—for industrial-level durability. The slender backband design sits comfortably under hard hats or helmets, and the foam ear cushions provide long-wear comfort without compromising situational awareness. These headsets offer a unisex fit and are well-suited for work in production studios, broadcast booths, and demanding field locations.

External Battery System Offers Flexible Power Management
Each UltraPAK uses a rechargeable lithium polymer battery that is charged externally and easily swapped in the field. With up to six hours of runtime per charge, users can keep extra batteries ready to go and replace them in seconds for uninterrupted operation. The included 8-port multi-charger provides rapid turnaround with individual LED indicators for charge status, helping teams rotate and manage power across multiple units efficiently.

HUB Base Station Connects Teams with Two-Channel Flexibility
At the core of the system is the HUB Mini, a compact digital repeater that supports up to eight wireless users simultaneously. The HUB includes two separate communication channels, with a channel combine button to merge all UltraPAK units into one talk group. For growing teams, the HUB itself can act as an additional transceiver, increasing capacity to nine. When two HUBs are bridged together, the system scales up to 16 users—all communicating in real time, full duplex.

HUB Interface Supports Hybrid Wired and Wireless Systems
For facilities already using wired intercom systems, the HUB Interface provides a practical way to add wireless mobility. It enables a seamless full duplex link between UltraPAK users and a hardwired base, allowing up to eight wireless crew members to communicate with wired staff as if they were cabled into the system. This makes it an excellent choice for theaters, auditoriums, houses of worship, and studios that need wireless coverage without replacing legacy systems.

Field Programmability Ensures Scalable and Future-Proof Operation
The Eartec UPMON6 is designed for flexible growth. UltraPAK units are field programmable, meaning you can add more headsets, HUBs, or transceivers to accommodate larger teams as your needs evolve. Whether you're building out a permanent system or expanding for a specific event, this modular solution adapts easily to growing communication demands.
