KFM 6

Common name: Schoeps KFM 6

Production Status: Discontinued / Vintage

The KFM 6 is a stereo sphere microphone providing a recording angle of 90°. This requires the microphone to be placed relatively far from the sound source and special attention should be paid to room reflections and acoustics. The sound source should be within a +/- 45° angle from the 0° axis. Sounds reaching the microphone at an angle exceeding +/-45° will be panned and reproduced as fully left and fully right by a typical two speakers arrangement. The opposite result will occur when the sphere is positioned further away as the room sound will increase relative to the direct sound and sources will ted to concentrate in the middle of the stereo image. The KFM 6 has very good imaging and sense of depth, good localisation and a very natural sound. The microphone works with both 12 and 48 V phantom power supply (with 12 V the maximum SPL is 7 dB lower than with 48 V). The KFM output is about 15 to 20 times greater than that of the Colette series microphones, providing several advantages including connection to line inputs of a recording device, greater immunity to electrical interference and connection to unbalanced inputs (via decoupling device such as the NG 52 Uv). Includes suspension with universal ball and socket joint and AKSU/2U adapter cable (XLR-5F to 2 x XLR-3M).
