Eartec UPMX4GS3 3-Person HUB Intercom System

Professional Wireless Intercom System for Three-Person Crews
The Eartec UPMX4GS3 UltraPAK intercom bundle is built for professionals who need clear, simultaneous communication while working hands-free. This compact 3-person system includes a HUB Mini Base Station, three UltraPAK Remote Beltpacks, and three Max 4G Single Headsets, all supported by four rechargeable lithium batteries, an 8-port charger, and a durable soft-sided case. Designed for production teams, construction crews, and field operators, this system allows you to talk in full duplex mode across a wide range without interruption.

Reliable Long-Range Connectivity with the HUB Base
The HUB Mini Duplex Base Station extends wireless intercom range by over 1000 feet, giving your team flexibility to move freely. Whether worn on a belt or placed at a central location, the HUB operates on DECT frequency, enabling simultaneous two-way communication over two selectable channels. It supports up to eight wireless headsets and even functions as an additional transceiver when necessary. A rechargeable LiPo battery and an AC adapter are included for dual power options.

Compact UltraPAK Beltpacks Built for All-Day Wear
The UltraPAK is one of the smallest and lightest full-duplex beltpack radios on the market, weighing just 2.5 oz. With an ergonomic form factor, it clips comfortably onto clothing or gear. It features intuitive volume control, a mic mute button, and LED indicators. Each unit runs up to six hours on a full charge, and the field-replaceable lithium battery design ensures minimal downtime on the job.

Max 4G Headsets Provide Comfort and Noise Isolation
Max 4G Single Headsets are engineered for demanding environments. These lightweight models feature a fully adjustable headband and noise-canceling boom microphones with a 270° rotation range. The leatherette ear cushion provides all-day comfort, while the automatic mic mute function activates when the boom is flipped up—making communication control simple and intuitive.

Efficient Charging with Multi-Port Charger Included
To keep your team powered and ready, this system includes an 8-port multi-bay charger capable of simultaneously charging UltraPAK and HUB batteries. LEDs provide real-time charge status—red for charging and green when ready. Fully charging a set of batteries takes approximately three hours, so you can cycle spares and reduce downtime.

Rugged Carrying Case for Transport and Storage
A medium-sized soft-sided case is included to keep all components secure and organized. Made from waterproof nylon, it includes internal compartments for belt packs, headsets, chargers, and accessories. A reinforced handle makes it easy to transport to any location, whether you're working indoors or out in the field.
