RSM 190 i
Common name: Neumann RSM 190 i
Production Status: Discontinued / Vintage
The RSM 190-i is the first stereo shotgun microphone manufactured by Georg Neumann GmbH. It had a really short market life as it was only available in 1987. It was suddenly replaced by the RSM 191-i, which is basically the same microphone with some improvements. The KK 190 MS is a double-pressure gradient capsule system. The two transducers are angled by 90° in a Mid-Side configuration. The axial one works as a lobe (shotgun) interference “middle” transducer, while the other one has a bidirectional polar pattern and provides the side information. A dedicated matrixing power supply unit has controls for side information and provides either stereo-decoded L-R outputs or direct M-S outputs at microphone level. The RSM 190-i is phantom powered (P 48) by the dedicated box and includes a shock mount and windscreen. It was only available in a dark matt finish.
