Now Shipping: Royer SF-24

Royer Labs’ SF-24 phantom-powered stereo ribbon microphone features two fully balanced, discrete head amplifier systems utilizing ultralow-noise FETs, each delivering an output sensitivity rating of –38 dB. The impedance-matching circuitry provides optimum impedance to the ribbon elements, preventing over-damping of the elements and ensuring consistent performance.

Housed in an ingot iron case that forms part of the magnetic return circuit, the SF-24 comprises two matched ribbon microphones placed one above the other, each aimed 45 degrees from center in the Blumlein configuration. The magnet/pole piece structure of each ribbon transducer allows a wide, uniform frequency range with no substantial peaks or dips. The two 1.8-micron pure-aluminum ribbons produce high-quality transient response. The SF-24’s cable incorporates a Y adapter that splits into separate 3-pin male XLR connectors labeled Upper and Lower for the instrument’s upper and lower, respectively, capsules. The SF-24’s package also includes a shock-mount, mic sock and protective case.
