Eartec UPSST8 8-Person HUB Intercom System

Eight-Person Full Duplex Wireless Intercom System
The Eartec UPSST8 provides a professional communication solution for teams of up to eight users who need clear, hands-free, simultaneous dialogue while staying active and mobile. This complete intercom package includes one HUB Mini Base Station, eight UltraPAK beltpack transceivers, eight SST “Secret Service Style” headsets, eight rechargeable lithium batteries, an 8-port charger, and a rugged soft-sided carry case. Built for production crews, coaching staff, training teams, or any workgroup requiring close coordination, the UPSST8 is a compact, license-free solution using Digital Enhanced Cordless Technology (DECT).

Ergonomic Beltpacks with Intuitive Controls
UltraPAK beltpacks are compact digital transceivers designed for users who need lightweight and reliable communication gear. Each unit weighs only 2.5 oz and is contoured to wear comfortably on a belt or waistband. Equipped with a volume control dial and a push-button mic mute function with an LED status indicator, UltraPAK provides full duplex communication over a range of up to 1/4 mile. A single lithium battery powers the unit for up to 6 hours and can be hot-swapped for extended use.

Discreet SST Headsets for Low Profile Applications
The SST headset is the smallest in Eartec’s lineup, designed for low-visibility use in environments where traditional headsets may be too bulky or visually obtrusive. Featuring a coiled acoustic tube with an earbud-style earpiece, SST headsets are ideal for stage crews, sports coaching, and production environments where discretion is critical. These lightweight headsets connect to the UltraPAK via dual 3.5mm/2.5mm plugs and offer secure, clear audio without interfering with movement or situational awareness.

Field-Replaceable Batteries with Long Runtime
Each UltraPAK is powered by a compact lithium-ion battery that charges in about three hours and runs for up to six hours in full duplex mode. Because the batteries are removable and externally charged, users can keep fresh batteries ready and swap them in seconds, minimizing system downtime. Whether for long rehearsals or full-day events, the UPSST8 supports continuous operation with minimal interruption.

Charge Multiple Batteries Simultaneously
The included 8-port multi-bay charger allows all eight lithium batteries to be charged at once, each in its own independent bay. Red and green LED indicators show charge status for each battery, so users can easily determine when a battery is ready. This charger makes it simple to rotate batteries between users or events without confusion or delay.

Durable Storage Case for Transport and Organization
To keep the system organized and protected, the UPSST8 comes with a waterproof nylon soft-side case with padded compartments. This storage solution keeps all components—headsets, beltpacks, batteries, and charger—neatly arranged. An extra storage pocket with hook and loop fastener secures spare batteries or cables, while the molded plastic handle makes the entire kit easy to carry on location.
