Eartec UPSST6 UltraPAK 6-Person HUB Intercom System

Six-Person Wireless Communication System for Hands-Free Teamwork
The Eartec UPSST6 is a six-user full duplex wireless intercom system built for crews that need reliable, uninterrupted communication while working with their hands. This all-in-one package includes the HUB Mini base station, six UltraPAK beltpack transceivers, six SST-style headsets, seven rechargeable lithium batteries, an 8-port charger, and a soft-sided transport case. Whether you’re coordinating a production crew, managing a live event, or coaching on the field, this lightweight and portable system provides seamless talk functionality over long distances.

Full Duplex Beltpack Radios with Professional DECT Performance
At the core of this system are six UltraPAK transceivers—lightweight, ergonomic belt-worn radios that support simultaneous voice communication using DECT (Digital Enhanced Cordless Telecommunications) protocol. Each transceiver weighs just 2.5 oz and includes essential controls such as a volume adjustment toggle, a mute button, and an LED status indicator for live mic monitoring. Operating within a quarter-mile range, UltraPAK allows team members to talk naturally without push-to-talk delays or signal dropouts.

Discreet SST Headsets Designed for Low-Profile Use
Each system includes Eartec's SST "Secret Service Style" headsets. These ultra-light headsets come equipped with clear acoustic tubes and single-earbuds for inconspicuous operation. The flexible transparent tubing and low-profile in-ear bud make them ideal for users in environments requiring discretion, such as broadcast sets, house of worship tech crews, or event production staff. With dual-pin 2.5mm/3.5mm connectors and a 3-foot cable, the SST headsets ensure compatibility with UltraPAK radios and a comfortable fit for extended use.

Flexible HUB Base Station Expands Communication Range and Users
The Eartec HUB Mini base station functions as the communication center of the system. Wearable on a belt or placed at a fixed station, the HUB enables full duplex communication for up to eight wireless users—perfect for expanding crew sizes. Powered by either an internal lithium battery or included AC adapter, the HUB delivers up to a 1/4-mile wireless range and offers two communication channels for added versatility. No FCC license is required, and setup is quick and user-friendly right out of the box.

Quick-Swap Rechargeable Batteries and Multi-Port Charging
Powering the system are seven field-replaceable lithium batteries, each capable of up to six hours of operation in full duplex mode. These batteries charge externally in the included 8-bay charger, making battery swaps fast and keeping downtime to a minimum. Each bay has an LED indicator that switches from red to green once the battery reaches full charge—typically within three hours—ensuring your system is always ready for action.

Durable Soft Case Keeps Everything Organized on the Go
The included medium-sized softside case is constructed of waterproof nylon with internal padded compartments to keep all components neatly stored and protected during transit. A Velcro-secured pocket holds the charger and spare batteries, while the molded hard plastic handle makes the case easy to transport to and from any work site or location.
