TECHNICAL INFORMATION
-Headphone Damage could occur to avionics equipment that is intended for use only with 600 Ohm headsets. If in doubt, consult the avionics equipment manufacturer.
-Impedance Monaural mode: 160 Ohms ON and OF Stereo mode: 320 Ohms ON and OFF
-Frequency response 15 Hz to 15 kHz Sensitivity: 92 dB SPL typical, measured at 1 mw, 1 kHz, full volume on a KEMAR ear simulator.
-Microphone (Electret) Bias required: 8 to 16 VDC through 220 to 2200 Ohms.Sensitivity: Varies depending on bias and AC radio input impedance. Typical output is 600 mV at 114 dB SPL. To assure proper modulation of the radio, it is recommended that an avionics technician adjusts its input to match the output of the microphone.
-Microphone (Dynamic) Impedance: 5 Ohm or 150 Ohm dynamic mic
-Sensitivity: Equivalent to M-87/M-101
-Maximum ambient noise level 115 dBC SPL for full active noise reduction performance
-Power source Battery-powered: Two (2) AA alkaline Aircraft-powered: 10 to 32 VDC
-Voltage Battery-powered: Two (2) AA alkaline batteries Aircraft-powered: 10 to 32 VDC
-Battery life Alkaline battery life: At least 45 hours in typical general aviation aircraft noise. Duration varies with battery age, ambient noise levels, temperature, ear cushion seal, and use of the Bluetooth feature.
-Current Operating: 25 mA in typical aircraft noise
-Fuse/breaker recommended 1/4 amp, fast-blow fuse (AGC 1/4 amp fuse) or 1/2 amp circuit breaker
-Headset weight 12 ounces
-Headset size range Slider not extended: 8.425" (214mm) H x 6.34" (161mm) W x 3.15" (80mm) D Slider extended: 10.2" (259mm) H x 6.6" (168mm) W x 3.15" (80mm) D
-Control module dimensions 1.5" (38.1mm) H x 1.5" (38.1mm) W x 4.92" (125mm) D
-Temperature and Altitude (Category A) Operating: 5 to 131°F (-15 to 55°C) Storage: -67 to 158°F (-55 to 70°C)
-Altitude: 15,000 feet maximum pressure altitude for full
