Modular ANR headset features automatically limited speaker output, high-bandwidth frequency response, and an advanced noise reduction system. It’s easy to experience the unmatched flexibility of the Ascend. A simple procedure allows you to change the connector, remove the boom or add a battery. The Telex Ascend has been meticulously designed and rigorously tested to meet the FAA TSO standards necessary for use in commercial aircraft. Ascend's advanced noise reduction system specifically targets common cockpit noises such as wind noise and avionics cooling fans. ANR can be powered by either mic bias or rechargeable battery module. The Telex Ascend is ideal for use in the cockpit or the cabin. The highly flexible design enables users to swap connectors and use the same professional-grade headset for commercial flying or personal audio applications. The Ascend is covered by a full three-year warranty. The solid construction is designed to prevail through the thousands of hours of flying time that dedicated pilots endure. Ascend's unique chassis features pivoting earcups, ensuring a snug, custom-fit for the user. The earcups pivot a full 180°, enabling the headset to fold flat for compact storage. The Ascend can change as your requirements change. A two-plug version used in a business or commercial jet will work just as well as when converted to a single-plug version for an Airbus. The Ascend is available in three different configurations: single-sided, dual-sided, and dual-sided with ANR (Active Noise Reduction).
