Welcome to the future of clear voice communication
Note: AFA Microphone capsules require DC bias voltage. Please ensure that your headset supplies the required voltage (2v to 10v DC)
Directivity (Voice Microphone) = Unidirectional
Directivity (Noise Microphone) = Omnidirectional
Frequency (f) = 100-20,000 Hz
Signal to noise ratio (S/N) = 81 dBA
Total Harmonic Distortion (THD) = 0.0038%
Sensitivity (S) = -50 to -39 dB
Output Impedance = 2.2k
Operating Temperature = -20 to 70°C
Standard operating voltage (Vs) = 2 Vdc
Max operating voltage = 10 Vdc
 
The AFA ELM-03 Noise Cancelling Microphone Capsule is designed to operate in place of carbon and amplified dynamic microphones.
NOTE: It will not operate in circuits that do not supply a DC bias voltage.
Most modern Motorsport & Aviation communications equipment does supply the required voltage. If unsure, consult with your radio technical manual or with your local technician.
