Damage could occur to avionics equipment that is intended for
use only with 600-ohm headsets. If in doubt, consult the avionics
equipment manufacturer.
Monaural mode: 160 ohms (ON) and 230 ohms (OFF) at 1 kHz
Stereo mode: 320 ohms (ON), 460 ohms (OFF)
15 Hz to 15 kHz
Sensitivity: 90 dB SPL typical, measured at 1mw, 1kHz, full
volume on KEMAR ear simulator
Bias required: 8 to 16 VDC through 220 to 2200 ohms
Sensitivity: Varies depending upon bias and radio AC input
impedance. Typical output is 300 mV at 114 dB SPL. To assure
proper modulation of the radio, it is recommended that an
avionics technician adjust its input to match the output of the
microphone.
Impedance: 5 ohms
Sensitivity: Equivalent to M-87/M-101
110 dB SPL
Battery powered: 9-volt alkaline
Aircraft powered: 10 to 32 VDC
Alkaline: Up to 20 hours in typical aircraft noise (decreases at
cold temperatures)
Operating: 25 ma in typical aircraft noise
