Neumann KM 183 mt stereo set - a pair of studio stereo microphones, consisting of two omni-directional KM 183 microphones, two SG 21/17 mt microphone stand mounts, and two WNS 100 windscreens, all housed in a robust wooden case for protection and transport. The set is ideal for use in X,Y audio signal recordings, as ambient microphones, or for instruments such as piano, string instruments, organ, or choir. Black finish.
