The heart of the SF-1 is its ribbon transducers proprietary  cross-field motor assembly. 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.

 Features
•No internal active electronics to overload or produce
distortion up to maximum SPL rating.
•Extremely low residual noise
•Ribbon element not affected by heat or humidity
•Absence of high frequency phase distortion
•Equal sensitivity from front and back of element.
•Consistent frequency response regardless of distance
•Very low magnetic leakage
•High efficiency toroid matching transformer and gold
plated output connector
•Ultra compact package
•Matte Black Chrome finish reduces reflected light for
on-camera use.
