Can you hear me now? You won't be having to say that when you're using this David Clark microphone in your cockpit. The David Clark M-7A amplified electret microphone (model 09168P-33) features advanced technology for crystal clear sound and exceptional noise cancellation. Install this high-performance microphone in place of carbon and amplified dynamic microphones for the highest speech intelligibility.

The David Clark M-7A is an amplified electret impedance microphone that transmits clearly, even when surrounding noise is as much as 120 dB SPL. This is the microphone you need for a noisy cockpit. It's lightweight and fits sleekly onto your current headset. This affordable replacement microphone will greatly enhance your communications at a low cost.

Note: The David Clark M-7A microphone requires circuits that supply a DC bias voltage. Most of today's aviation communications equipment does supply this required voltage, but if you're not sure, check your radio's manual or give SkyGeek a call!

  • DC Supply voltage and source resistance: 8 to 16 volts, ee0 to 2200 ohms-not polarity sensitive.
  • Output voltage, 1000 HZ for 114 dB SPL (re:.002 microbar) input, as a function of DC source resistance and AC input impedance.*Note-Electrical specifications are given for two earphones wired in parallel.

  • Frequency Response: designed for optimum speech intelligibility and noise cancellation.
  • Ambient noise level: Communications can be carried on in noise levels up to 120 dB SPL(re:.0002 microbar) with adequate signal to noise ratio. Microphone must be zero to 1/8" from lips at corner of mouth for best signal to noise ratio (maximum noise cancellation).
