Description

The SF-24V ribbon microphone is the pinnacle of our stereo ribbon microphone designs. With the inclusion of vacuum tube circuitry derived from our TEC Award winning R-122V, the SF-24V provides unmatched clarity, detail, midrange reach, and an airiness previously unknown to ribbon microphones. For orchestra, acoustic instruments and all critical stereo applications, the SF-24V is perfection.
