Electrical characteristics.
Receiver.
Output level. The receiver output level shall be 75.5± 4 dB SPL (12.6 mV rms through 600 ohms).
Distortion. Distortion for the headset shall be less than 5 percent.
Receiver impedance. The receiver impedance shall be 600 ohms nominal.
Microphone/amplifier.
Output level. The output level shall be -22.5 dB V ±4 dB V (47 to 119 mV rms).
(NOTE: All transmit measurements are made with 94 dB SPL drive at 1000 Hz into a 50 ohm resistive load at 100
mA dc. Also 0 dB m = 1 milliwatt; 0 dB SPL = .0002 dynes/cm2; 0 dB V = 1 volt.)
DC resistance. The dc resistance shall be greater than 35 ohms.
Terminal voltage. Terminal voltage shall be 4.7 V dc at 100 mA.
Microphone impedance. Microphone impedance shall be 50 ohms nominal.
Polarity. The microphone/amplifier shall be nonpolar.
Marking. Headsets supplied to this CID shall be marked with the manufacturer's (MFR's) standard commercial PIN.
