Eartec UPMX4GS7 7-Person Full Duplex Wireless Intercom

Professional Wireless Intercom for Seamless Crew Communication
The Eartec UPMX4GS7 is a complete 7-person full duplex wireless intercom system built for teams who require real-time communication while keeping their hands free. Featuring seven UltraPAK beltpack transceivers paired with seven Max 4G single headsets, this bundle includes the HUB Mini Base Station, rechargeable batteries, an 8-port charger, and a soft-sided case for transport. Designed for live production, construction, broadcasting, and industrial coordination, this system ensures continuous talk communication across a quarter-mile range.

Compact UltraPAK Beltpacks with All-Day Comfort
UltraPAK beltpacks are lightweight, weighing only 2.5 oz, and feature a durable clip-on design for secure, all-day wear. These transceivers include volume control, a mic mute button, and a bright LED status indicator. Using DECT technology, UltraPAK devices provide simultaneous voice transmission without dropouts or lag. Each unit operates up to six hours per charge and uses field-replaceable lithium batteries for quick power swaps in active environments.

Max 4G Single Headsets Deliver Clear and Reliable Audio
Each Max 4G single headset includes a padded ear cup, flexible boom mic, and adjustable headband for secure, comfortable fit. The microphone arm rotates 270° and features AutoMute technology that silences the mic when lifted. Engineered with noise-canceling electret condensers and lightweight construction, these headsets are ideal for high-noise job sites or long-duration events where constant clarity is critical.

Versatile HUB Mini Base Offers Mobile Range Extension
At the core of this system is the HUB Mini Duplex Transceiver Base, allowing up to 8 wireless users to communicate simultaneously. It features two communication channels and supports dual power modes—battery or AC power—ensuring flexibility in field or fixed installations. Compact enough to clip to a belt, the HUB extends range up to 1,000 feet line-of-sight, making it easy to deploy for mobile crews.

Fast Battery Charging with the 8-Port Multi-Charger
This bundle includes an 8-bay charger that rapidly recharges all included lithium batteries. LEDs clearly indicate charging status, turning green when batteries are ready to use. External charging allows batteries to be rotated while systems stay live, helping teams stay connected with minimal downtime.

Transport-Ready with Durable Soft-Sided Case
A rugged soft case is included for organizing and storing the complete system. Made from water-resistant nylon with internal dividers, this case keeps headsets, beltpacks, batteries, and accessories protected and sorted for quick deployment.
