Neumann KM-131 Omnidirectional Free Field Equalized Microphone with SG 21 BK – WNS 100 – Woodbox
The Miniature Microphone KM 131 The variable condenser miniature microphone system consists of several active microphone capsules with different directional characteristics, an output stage, and numerous accessories. Currently there are seven active capsules available: omni diffuse-field equalized, omni free-field equalized, cardioid, wide-angle cardioid, cardioid with bass roll-off, hypercardioid, and figure-8. Through the modular construction of mic capsules and the output stage it is very easy to adapt the system to a wide range of applications. The mic becomes nearly invisible during work with cameras (film, video), on stage, or suspended from the ceiling in a concert hall. An active capsule can also be screwed directly onto the output stage. The result is a compact miniature microphone.
