Royer Sf-2 Matched Pair.
The Royer Labs SF-2MP is a matched pair of active ribbon microphones designed for high-resolution recording of acoustic instruments, ensembles, and classical performances. By combining Royer’s ribbon transducer design with active electronics, the SF-2 delivers condenser-like output levels while preserving the smooth, natural sound ribbon microphones are known for.
Each microphone features a custom FET-based active circuit powered by standard 48V phantom power, providing high output and consistent impedance regardless of the preamp used. With a sensitivity of -38 dB, the SF-2 can be used with virtually any professional microphone preamp without requiring excessive gain.
The SF-2’s 1.8-micron ribbon element and precision magnet structure provide fast transient response, wide frequency range, and minimal off-axis coloration. Its bidirectional polar pattern offers equal sensitivity from the front and rear, making it ideal for stereo recording techniques, room capture, and ensemble miking. Designed for reliability, the SF-2 resists damage from phantom power, electrical spikes, and long cable runs.
