The SF-24 stereo ribbon microphone is a phantom-powered version of our popular SF-12 stereo ribbon microphone. It combines the SF-12's high-quality audio performance, outstanding stereo separation, and imaging with our exclusive active electronics system for ribbon microphones. The SF-24's output of -38 dB is a full 14 dB more sensitive than our non-powered SF-12, putting its sensitivity on par with that of phantom powered condenser microphones. The unique electronics and custom-designed FET's used in the SF-24 allow for ultra-quiet operation, with self-noise of lower than 18 dB. Like an SF-12, the SF-24 is actually two matched ribbon microphones placed one above the other in a coincident pair, each aimed 45 degrees from center in the classic Blumlein configuration. The magnet/pole piece structure of each ribbon transducer delivers a wide, uniform frequency response with no substantial peaks or dips, and the 1.8-micron ribbons produce superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible. The SF-24's extension cable comes with a Y adapter that splits into separate 3-pin male XLR connectors labeled “Upper” and “Lower” for the upper and lower capsules of the microphone (when held vertically). Features: • Phantom powered circuitry provides high output and impedance matching • True stereophonic (Blumlein and M-S) recording from one microphone • High SPL capabilities • No distortion up to maximum SPL rating • Extremely low residual noise • Ribbon elements are not affected by heat or humidity • Absence of high frequency phase distortion • Equal sensitivity from front or back of elements • Consistent frequency response regardless of distance • High efficiency, matching toroidal transformers • Very low magnetic leakage

What is the SF-24 Stereo Acive Ribbon Microphone?
Ribbon microphones capture the top end gently rather than exaggerating it, which is why they sit so well on guitar cabinets, brass and drum overheads where a bright condenser turns brittle. The figure-of-eight pattern also rejects sound from the sides, giving useful control over what the microphone does not hear.

Why choose Royer Labs?
Ribbons are the classic answer to a source that sounds harsh on everything else. They are the difference between taming a guitar amp at the source and fighting it with EQ afterwards.
Frequently asked questions
What is a ribbon microphone good for?
Guitar cabinets, brass, strings and drum overheads. Anywhere a condenser sounds harsh.
Does it need phantom power?
Passive ribbons do not, and phantom can damage some. Active models require it. Check the specification.
Is it fragile?
Modern ribbons are robust, but avoid blowing into them and use a windscreen outdoors.
Do you supply matched pairs?
Yes where listed. Call 844-687-4208 for stereo pairs.
