SF-2 - Active Ribbon Microphone Deluxe Edition
The SF-2 ribbon microphone is a phantom powered version of our original SF-1 ribbon microphone. Designed primarily for classical applications and acoustic instruments, the SF-2 combines high-quality audio performance with our exclusive active electronics for ribbon microphones. The SF-2's output of -38 dB puts its sensitivity on par with that of phantom powered condenser microphones, allowing it to be used with a wide variety of mic pre's regardless of gain characteristics. The unique electronics and custom designed FET's used in the SF-2 deliver ultra-quiet operation, with self-noise of lower than 18 dB.
The SF-2's magnet/pole piece transducer structure gives a wide, uniform frequency response with no substantial peaks or dips, and the 1.8-micron ribbon element delivers superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbon and off-axis coloration is negligible.
