From Neumann, the RSM 191 A-S is a professional stereo shotgun microphone system designed for crucial recording and live sound reinforcement applications. The system consists of the RSM 191 microphone and MTX 191 matrix amplifier. The revolutionary design of the RSM 191 begins with it's dual capsule system. A hypercardioid element and a figure-8 element exist in a short shotgun housing. Together the capsules generate the mid and side signals necessary to achieve either M-S or X-Y style capturing.
The MTX191 matrix amplifier is the control center, output stage and power supply for the microphone. The MTX191 features controls to adjust the width of the stereo image by adjusting the side signal gain. The controls may be used to widen a stereo perspective or create a focused, narrow pick up with exceptional attenuation of residual off-axis noise. The output stage features dual (stereo) 3-pin XLR outputs. The MTX191 is capable of +48 V phantom power via an external source or internal 9-volt battery (8 hours typical).
Neumann's dedication to excellence is apparent in the overall sound quality of the RSM 191 A-S. As a stereo microphone the imaging and detail is reproduced with stunning accuracy in either M-S or X-Y configurations. As a shotgun, the focused pick up pattern provides an off-axis rejection that rivals dedicated shotguns in the same price range. The RSM 191 AS is a formidable choice for film, television, Electronic News Gathering (ENG), orchestra capturing, ambiance capturing and more.
