The Royer Labs SF-24 Stereo Ribbon Microphone is an active, phantom-powered evolution of the renowned SF-12, combining the SF-12’s superior stereo imaging and separation with enhanced sensitivity for versatility across various recording environments. With a -38 dB output—14 dB higher than the SF-12—the SF-24 achieves condenser-level sensitivity, allowing compatibility with most mic preamps. Royer’s custom FET design provides ultra-low self-noise under 18 dB, ideal for capturing quiet, nuanced sound sources.

Built with dual matched ribbon elements in a Blumlein configuration, the SF-24 ensures pristine stereophonic capture. The microphone’s unique crossfield magnet/pole piece structure supports a broad frequency response and minimizes off-axis coloration. Featuring a low-impedance output, the SF-24 performs consistently on long cable runs with minimal signal degradation. The SF-24’s active electronics maintain optimal impedance matching, preserving the microphone’s full sonic range.
