The SF-1 is an ultra-compact, monaural ribbon microphone, exhibiting flat frequency response and a well-balanced, panoramic soundfield. The SF-1 has superb transient response due to its ultra low-mass 1.8-micron ribbon assembly. Frequency response is excellent regardless of the angle of sound striking the ribbon, and off-axis coloration is negligible.

The heart of the SF-1 is its proprietary cross-field ribbon transducer. Comprised of four powerful Neodymium magnets and Permendur iron pole-pieces, the cross-field design assures the shortest front-to-rear ribbon path length for best high frequency response. The case is fashioned from ingot iron and forms the magnetic return circuit, an effective system with low leakage flux which accounts for the relatively high sensitivity in a trim package.

No internal active electronics to overload or produce distortion up to maximum SPL rating.
