Neumann KM100F

The KM 100 F output stage is an alternative to the KM 100 output stage. In contrast to the KM 100 output stage with a flat frequency response, the KM 100 F attenuates frequencies below 80 Hz at 6 dB/octave. This eliminates or suppresses interference caused by wind or structure-borne noise. A built-in slide switch allows to raise the cut-off frequency (-3dB point) from 80 Hz to 120 Hz. An additional slide switch lowers the sensitivity by 10 dB.
