Frequency Response: 250 Hz to 4 KHz (tuned for voice frequency range) Ambient Sound Speakers: One ambient sound speaker is mounted on a circuit board inside of each earcup. Impedance: 32 ohms Output: 90 dBa (max) Frequency Response: 300 Hz to 6 KHz LIBERATOR II HEADSET (CONTINUED): Headset Weight: Approx. 300 grams Earcup Dimensions: Approx. 108 MM x 84 mm (H x W) Max. thickness of earcup approx. 28 mm Min. thickness of earcup approx. 12 mm Headset Environmental Standards: MIL-STD 810 C,D,E,F IP-68 Headset Operating Temperature: -55 C to +85 C Headset Immersion Rating: 1 Meter, 15 mins. Headset Cable Length: Approx. 150 MM (including plug) Cable Thickness: Approx. 5.1 MM Headset Connector: Over molded onto Polyurethane cable jacket for high axial strength, reliability and durability. Nexus brand TP-120 connector PRESS-TO-TALK UNIT (PTT): Designed to be enough to be used during tactical situations and gloved hands but not so large to interfere with movement or usage of other equipment. The PTT provides the user with an easy, intuitive and effective means of connecting and utilizing a tactical radio with Liberator II, TECS and other TCI Tactical Headsets. The PTT is environmentally sealed to insure reliability in harsh and demanding situations. The PTT features an ambidextrous design, heavy duty clothing clip (Molle/PALS compatible), remote finger PTT jack and factory mutually approved radio interface connector. PTT Enclosure Type: Circular, ambidextrous Injection molded composition resistant to abrasions, chipping or cracking, including an internal O-ring seal. The front surface of the PTT has a recessed area approx. 28 MM in diameter to protect accidental keying during movement, yet allows easy access to the PTT button with a gloved hand. Size: Approx. 52 MM x 52 MM x 32 MM (H x W x D) Weight: Approx. 250 grams (with cable and connector) Operating Cycles: 30,000
