The system's dual-channel functionality allows for versatile conferencing options, enabling you to split users into two groups of four or unite everyone in a single conference mode. The digital full duplex voice technology ensures crystal-clear audio quality, eliminating frustrating delays and voice activation requirements. Each XTreme Wireless Headset is designed with comfort and durability in mind, featuring deluxe padding, noise cancellation, and the ability to fit comfortably under a hard hat. The headsets are equipped with positionable boom microphones, complete with foam windscreens to minimize wind noise and breath pops, ensuring your voice is transmitted with ultimate clarity. The COMSTAR system is remarkably portable and simple to set up, making it ideal for on-location use in various industries such as construction, crane operations, avionics, and defense. It requires no FCC license for operation, as it utilizes the 1900MHz frequency band reserved for "PCS" voice communication. Each headset boasts a rechargeable lithium battery offering up to 10 hours of operation, while the Com-Center features a rechargeable NiMH battery with up to 6 hours of operation. Additional powering options include an AC wall plug and a battery sled for disposable AA batteries. A multi-port desktop charger is provided for convenient simultaneous charging of both the Com-Center and headset batteries. In summary, the COMSTAR XT 4-User Full Duplex Wireless System is a reliable, innovative, and user-friendly communication solution that ensures efficient, uninterrupted collaboration for teams that need to stay connected while working with their hands.
