The Microphone Madness FGNC-1 is a 7" long, stereo gooseneck microphone featuring dual cardioid capsules. The 1/8" connection is completely compatible with microphone inputs found on MiniDiscs, Dat recorders and analog portable recorders that supply a bias voltage of 1.5 to 10 volts D.C. (also known as plug in power). The cardioid polar pattern is effective in minimizing off-axis noise and ambiance. The microphone provides a signal response that features smooth mid-range, and clean high frequency response for maximum detail.
