Neumann RSM191

The microphone has a dual capsule systems, a hypercardioid element and a figure-8, both in a short shotgun. Together they generate the mid and the side signals. The matrix amplifier controls the width of the stereo image by changing the gain of the side signal relative to the middle signal in six 3dB steps. The output signals of the matrix amplifier are either mid-side (MS) or left/right (XY). The balanced, transformerless technology permits the use of long cables between the microphone, the matrix amplifier and the following mic input of other signal processing equipment.
