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

Combines stereo ribbon microphone performance with phantom-powered active electronics, delivering higher output and improved impedance matching. This allows the microphone to perform consistently with a wide range of preamps while capturing both quiet and loud sound sources with clarity, making it suitable for professional studio and live recording environments.
Features two matched ribbon elements arranged in a precise Blumlein configuration, providing accurate stereo imaging and natural spatial depth. This design captures sound with realistic placement and balance, making it ideal for recording ensembles, acoustic instruments, and environments where detailed stereo reproduction is essential.
Offers significantly higher sensitivity compared to passive designs, with output levels comparable to condenser microphones. The active circuitry and custom FET design ensure ultra-low noise performance, allowing for clean signal capture across a wide dynamic range, from subtle acoustic details to louder sound sources.
Engineered to handle high sound pressure levels without distortion, maintaining clarity even in demanding recording situations. Suitable for loud sources such as drums, electric guitar amplifiers, and brass instruments, while still delivering detailed and natural sound on quieter sources.
Designed for flexibility across a wide range of stereo recording applications, including Blumlein and mid-side techniques. Its ability to capture both direct sound and ambient space makes it ideal for orchestras, ensembles, room miking, and professional audio production requiring accurate stereo imaging.
