Eartec UPMX4GD1 UltraPAK Intercom System

Hands-Free Full Duplex Communication in a Compact Beltpack Solution
The Eartec UPMX4GD1 system combines the lightweight UltraPAK beltpack with the double-ear Max 4G headset to give professionals reliable, full duplex communication in hands-free environments. Whether you're managing a live production, directing a team on set, or coordinating staff across a job site, this system is engineered to let you talk simultaneously with no push-to-talk buttons and zero transmission delay. Compact, easy to wear, and long-lasting, this one-to-one solution is perfect for users who need clear and consistent communication without the bulk of larger systems.

Ultrapak Beltpack Designed for Comfort and Mobility
Weighing just 2.5 ounces, the UltraPAK digital beltpack is an ergonomic communication unit designed to be worn all day. It features a sealed mic mute button with LED indicator that glows when the mic is muted, along with intuitive volume controls for quick adjustments on the fly. It clips securely to a belt or pocket, allowing the user to remain mobile and connected across environments like event venues, studios, industrial sites, and more.

Field-Replaceable Lithium Battery with Long Runtime
Each UltraPAK includes a lightweight rechargeable lithium battery that fits into a dedicated compartment on the unit. These batteries charge externally, so there’s no need to plug the beltpack in during downtime. With approximately six hours of continuous operation per charge and just three hours to fully recharge, they provide a seamless power solution. Keep spare batteries on hand for fast change-outs during long shifts without interrupting workflow.

Max 4G Headset Delivers Comfort and Audio Clarity
The Max 4G double-ear headset offers superior audio isolation and comfort in high-noise environments. Built with deluxe foam padding, the headband and earcups are designed for long-wear performance. Its rotating boom arm offers 270° of adjustment, and when flipped to the upright position, the built-in AutoMute Boom Technology automatically disables the microphone—a smart feature that prevents unintended transmission during breaks.

Ideal Headset System for Live Events, Broadcast, and Industrial Use
This UPMX4GD1 system is built for users who require dependable one-on-one communication, especially in situations where freedom of movement is crucial. With no base station required, the UltraPAK and Max 4G headset work together as part of a scalable wireless system, making it easy to integrate with larger Eartec UltraLITE networks or use as a standalone communication solution.
