Many years ago, when they were first introduced, ribbon microphones used to be extremely delicate and very expensive, but with the advancements in modern materials some of the ribbon mics available today are very durable and can even find a home on stage with high SPLs. Designed primarily for classical applications and acoustic instruments, the SF-2 combines high-quality audio performance with Royers 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 st
