Royer Labs SF-2 Active Small-Diaphragm Ribbon Microphone

Royer's phantom-powered version of the SF-1, this high-output ribbon shines on acoustic instruments, choirs, orchestras, and overhead/distance applications.

The Royer Labs SF-2 is a compact, monaural, phantom powered active ribbon microphone, exhibiting flat frequency response and a well balanced, panoramic soundfield. The SF-2 has superb transient response due to its low-mass 1.8-micron ribbon element. Frequency response is excellent regardless of the angle of sound striking the ribbon, and off-axis coloration is negligible.

The heart of the SF-2 is its ribbon transducer's proprietary crossfield 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 maximum high frequency response. The SF-2's active electronics produce an output comparable to studio condenser microphones, while providing an optimum load to the ribbon at all times. The low output impedance of the SF-2 enables it to operate with any microphone pre-amplifier of average gain and impedance characteristics, and makes it suitable for use with long cable runs.
