The COMSTAR XT-4S 4-User Full Duplex Wireless Intercom System from Eartec is a fully functional wireless intercom that offers full duplex communication in a simple design which does not require the use of beltpacks. The system consists of a Com-Center base station and four wireless headsets. Additional headsets can be added to the system, allowing you to create a wireless network of up to eight users who can all communicate simultaneously with no delay or voice activation, ideal for applications where teams need full use of their hands. You can even split users into two groups of four people, or bring everyone together in conference mode.
Each headset connects wirelessly to the Com-Center at distances of up to 500M in any direction, allowing the headsets to be up to 700M 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.
