    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!
