Royer SF-24V Stereo Tube Ribbon Microphone

The SF-24V incorporates vacuum tube circuitry, which provides a higher output level and a distinctively warm, airy character compared to passive ribbon designs. This active design also allows it to drive long cable runs without signal degradation.

Yes, the SF-24V is fully mono-compatible. Because the two ribbon elements are perfectly coincident, you can sum the signals to mono without worrying about phase cancellation or comb filtering.

Yes, the SF-24V includes a dedicated external power supply unit to provide the necessary voltage for its vacuum tubes. You will need to connect the microphone to this power supply using the included cable before routing the signal to your preamp.

With a maximum SPL rating of 130dB, it can handle most acoustic instruments and guitar cabinets comfortably. However, as with any ribbon microphone, you should avoid placing it directly in front of high-velocity air blasts.

The coincident-pair configuration allows you to easily set up Blumlein stereo or Mid-Side (M-S) recording. It is an excellent choice for capturing natural room ambiance, orchestral ensembles, or acoustic piano.

No, the active tube electronics provide high output sensitivity, meaning you don't need a specialized high-gain preamp to achieve a clean, noise-free recording. It works well with standard professional-grade microphone preamplifiers.
