Neumann GFM 132 Description
The problem solver for special recording situations. The uniform frequency response for all angles of incidence, with an increase in the upper frequency range, ensures clarity and presence even when recording distant sound sources. However, optimal results are also obtainable when the mic is located in the bass drum!
The GFM 132 is a boundary layer microphone. Through computer simulation Neumann optimized the design to be free of any comb filter effects due to reflections, typical of other such microphones. The smooth frequency response for all angles of incidence exhibits a rise in the upper frequency range. This assures that all sound sources, even distant ones, will be recorded with clarity and presence.
Therefore, typical applications are for live recordings, such as in the orchestra pit of opera houses, theaters, and on stage.
The back of the microphone has non-slip pads for its use in a horizontal or inclined position, and holes for wall suspension. It is supplied with a wooden case and a wind screen.
