  • Full Duplex Communication
  • Up to 800-Yard Wireless Range
  • No Beltpacks Needed
The COMSTAR XT-2 2-User Full Duplex Wireless Intercom System from Eartec is a fully-functional wireless intercom that offers full-duplex communication in a simple design that does not require the use of beltpacks. The system, which is intended for use in Australia, consists of a Com-Center base station and 2 COMSTAR Single-Ear wireless headset transceivers. Additional headsets can be added to the system, allowing you to create a wireless network of up to 8 users who can all communicate simultaneously with no delay or voice activation. This is ideal for applications where teams need full use of their hands. In an expanded system, you can even split users into 2 groups of 4 people, or bring everyone together in conference mode.

Each headset connects wirelessly to the Com-Center at distances of up to 400 yards in any direction, allowing the headsets to be up to 800 yards apart while still enjoying full communication capabilities. The around-ear cushions and padded headbands provide lasting comfort for all-day use. Integrated controls make it easy to adjust the volume of the headsets and program them in the field. The COMSTAR system is self-tuning, so no remote antenna is needed.

Each headset has a microphone at the end of a positionable boom, allowing the user to place the mic in the best spot for more precise vocal pickup. A foam windscreen reduces the effects of wind noise and breath pops for clear transmission and reception. The headsets have rechargeable lithium batteries that provide up to 10 hours of operation, while the Com-Center has a rechargeable NiMH battery that provides up to 6 hours of operation. The Com-Center also has an AC wall plug and a battery sled for disposable AA batteries to give you additional powering options. A multi-port desktop charger is included that allows you to charge the Com-Center and headset batteries simultaneously. The XT-2 comes packaged inside a padded case to neatly and safely carry and store all of the system's components.
