Description
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 Royer’s 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 are 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.
