Eartec UPMX4GS1 UltraPAK Intercom System

Compact Wireless Intercom System for One Person Communication
The Eartec UPMX4GS1 is a professional one-user wireless intercom solution designed for people who need to talk hands-free while staying mobile. This system includes one UltraPAK remote beltpack transceiver, one Max 4G single-ear headset, and one rechargeable lithium battery. Built for reliability and clarity, it enables continuous full-duplex voice communication within a 400-yard range using DECT wireless technology. Ideal for solo operators who need to stay connected in fast-paced environments like broadcast, AV production, and industrial coordination.

Lightweight Beltpack with Comfortable Ergonomic Fit
The UltraPAK is a compact, belt-worn transceiver that delivers hands-free performance without bulk. Weighing only 2.5 ounces, it’s built with a contoured shape that fits securely on your waist or clipped to gear. A mic mute button with a red LED indicator provides clear visibility of mic status, and the unit includes a convenient volume control for on-the-fly audio adjustments. Its rechargeable lithium battery provides up to 6 hours of continuous use per charge.

Noise-Canceling Headset with Adjustable Fit and Auto-Mute
The Max 4G single headset offers a lightweight design with deluxe padding and a fully adjustable headband for long-wear comfort. The boom mic rotates a full 270° and features AutoMute technology that automatically cuts off mic signal when flipped upright. The electret-condenser microphone offers noise-canceling performance for clean, clear audio even in noisy environments. A 3' molded cable with dual 3.5mm and 2.5mm connectors ensures secure integration with the UltraPAK.

Plug-and-Play Wireless Setup for Fast Deployment
This system requires no complex setup, frequency coordination, or FCC licensing. Just power up the UltraPAK, connect the Max 4G headset, and you’re ready for seamless full-duplex communication. The UPMX4GS1 is ideal for individuals working on small production teams, technical crews, or stage setups where a wired intercom would hinder movement and efficiency.

Rechargeable Battery for Extended Operation
Included with the UltraPAK is a compact rechargeable lithium battery that installs directly into the beltpack compartment. Each battery charges in approximately three hours and provides up to six hours of runtime. The field-replaceable design means you can swap out charged spares quickly without taking the unit offline—perfect for extended shifts or mobile operations.

Durability and Practicality in Demanding Environments
Every component of the UPMX4GS1 is engineered for professional use. The headset and beltpack are rugged enough to withstand the rigors of daily work in production, warehouse, or industrial settings, yet lightweight enough to minimize fatigue. Whether you're coordinating events, cueing talent, or managing a team remotely, this single-user system provides critical voice communication without compromising mobility.
