For a microphone that features advanced noise cancellation technology and high speech intelligibility, try the David Clark 09168P-33. This microphone can be installed in place of carbon and amplified dynamic microphones for crystal clear, uninterrupted sound. The David Clark M-7A requires circuits which supply a DC bias voltage, common in most updated aviation communication systems. This amplified electret impedance microphone can transmit clearly with a surrounding noise level as high as 120 dB SPL. If you're looking for a microphone that will perform inside your noisy cockpit, the David Clark M-7A delivers. This lightweight product will fit snugly onto your current headset and improve your communication quality. Don't waste hundreds replacing your headset; this accessory is priced to fit your budget and help you save. Simply replace your microphone with the M-7A amplified electret and communicate with the clarity and precision you expect from our David Clark products.
- DC Supply voltage and source resistance: 8 to 16 volts, 0 to 2200 ohms-not polarity sensitive.
- Output voltage, 1000 HZ for 114 dB SPL (re:.0002 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).
