Eartec XT-4AU 4-User Full Duplex Wireless Intercom System

Reliable Hands-Free Communication for Production Teams
The Eartec XT-4AU Comstar is a four-person full duplex wireless intercom system designed for professional users who need simultaneous, hands-free voice communication without bulky belt packs. Each headset is self-contained with its own built-in transceiver, and the centralized Com-Center base allows up to four users to talk freely without delay, interference, or the need for push-to-talk. This model is optimized and certified for use in Australia and is ideal for AV teams, sports coaches, and production crews.

Dual Channel Base With Conference Mode Options
At the heart of the system is the Com-Center Dual Channel Base Station. With a range of up to 400 yards in any direction, the base supports up to 8 users in total (4 per channel) and includes a conferencing feature for linking all users together. The self-tuning system eliminates complicated setup—just power it up using the included AC adapter, lithium battery, or AA sled, and you're ready to go. No external antennas are required, and no FCC license is needed.

All-In-One Headsets With No Beltpacks or Cables
Each XT-4AU system includes two single-ear and two double-ear COMSTAR headsets. These headsets eliminate the need for wires and belt pack transceivers by integrating the transmitter directly into the earcup. The adjustable boom microphones offer clear voice pickup, while around-ear cushions and padded headbands provide comfort during long shifts. Headsets are field programmable and operate on the secure 1900 MHz PCS band for interference-free communication.

Long-Lasting Rechargeable Batteries and Multiport Charger
Each headset runs on a rechargeable lithium-ion battery that delivers up to 10 hours of talk time. The Com-Center base runs for up to 6 hours on its included NiMH battery and also supports power from an AC wall plug or AA battery sled for field flexibility. The included multi-port desktop charger charges all headset and Com-Center batteries simultaneously. LED indicators provide clear battery status for quick readiness checks.

Compact Padded Case for Transport and Storage
To make transport easy and protect your gear, the system includes a rugged padded carrying case. With custom foam inserts, the case securely holds the Com-Center, headsets, charger, and accessories. Whether you're working on location or organizing crew communications on set, the case keeps your intercom system organized and ready for action.
