AMPLIFIED DYNAMIC MICROPHONE DC-1A

The David Clark DC-1A Microphone with a male-to-male pigtail is a noise-cancelling, amplified dynamic microphone.

This mic replaces the M-1/DC microphone (P/N 12948G-01). Provides clear, crisp voice transmission.

• DC supply voltage and source resistance: 8 to 16 volts, 220 to 2200 ohms - not polarity sensive
• Output voltage of 40 mV, +/-3dB 1000 Hz for 94 SPL (re. .0002 microbar) input as function of DC source resistance and AC load impedance
• Frequency response: designed for optimum speach intelligibility and nolse cancelation
• 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 (max noise cancellation).
