Overview:

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.

-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
