Eartec UPSST4 UltraPAK 4-Person HUB Intercom System

Compact Wireless Intercom System for Hands-Free Team Communication
The Eartec UPSST4 is a complete 4-user full duplex wireless intercom system built for professionals who need to coordinate clearly and reliably while staying mobile. This bundle includes a HUB Mini base station, four UltraPAK remote beltpacks, four SST single-ear headsets, five rechargeable lithium batteries, a rapid-charging 8-bay charger, and a soft-sided case. It’s an ideal solution for teams working in event production, education, coaching, and industrial environments.

Wireless Clarity with Full Duplex UltraPAK Beltpacks
Each included UltraPAK beltpack operates on DECT (Digital Enhanced Cordless Telecommunications) technology to ensure reliable, interference-free wireless communication up to a quarter-mile in range. The units weigh just 2.5 ounces and clip comfortably to clothing, providing long-wearing comfort during extended use. Each UltraPAK also features user-friendly controls, including volume adjustment and a mic mute button with an LED status light.

Discreet SST Headsets with Secret Service Styling
The SST headset features a clear acoustic tube and single earbud for discreet monitoring—perfect for coaching, production teams, or anyone needing a low-profile communications solution. The flexible audio tube and earbud ensure comfort and clarity without drawing attention. A two-pin connector (3.5mm/2.5mm) provides compatibility with UltraPAK beltpacks, while the 3-foot cable offers ample reach and flexibility.

Expandability and Range with the HUB Mini Base Station
The system is centered around Eartec’s HUB Mini duplex transceiver, which supports up to 8 wireless users and one wired headset. The HUB can be belt-worn or placed on a table and includes two communication channels, a rechargeable LiPo battery, and an AC power option. The HUB increases overall range by more than 1000 feet and eliminates the need for FCC licensing, making it a plug-and-play solution right out of the box.

Efficient Battery Management with Multi-Port Charger
Included are five rechargeable lithium batteries and an 8-bay multi-charger for uninterrupted workflow. The charger’s individual LED indicators turn from red to green once each battery reaches full capacity, ensuring easy monitoring. Charge times are approximately three hours per battery, and the system supports hot-swapping, minimizing downtime on the job.

Durable Transport and Storage Case for Easy Mobility
Eartec’s medium soft-sided case is made of rugged, waterproof nylon and features padded internal compartments to organize and protect your gear. The molded hard handle ensures easy transport from location to location, whether you’re heading to a rehearsal, tournament, or remote work site.
