PROBLEM TO BE SOLVED: To obtain a condenser stereo microphone of narrow directivity compatible with plug-in power.SOLUTION: The condenser stereo microphone includes: a mid-condenser microphone unit 10 whose directional axis is disposed along the main axis of a microphone main body; and left and right side condenser microphone units 20, 30 whose directional axes orient to a direction orthogonal to the main axis and which are disposed symmetrically to sandwich the main axis. A connection is made in such a manner that the output of the mid-condenser microphone unit 10 is added to the left and right side condenser microphone units 20, 30, which are connected to a connector terminal 21 for a left channel and a connector terminal 22 for a right channel, respectively. The connector terminals 21, 22 for left and right channels are connected to the mid-condenser microphone unit 10 through power supply resistors 11, 12, respectively. |
