    The Royer Labs SF-24V is the world's first vacuum tube stereo ribbon microphone, delivering the ultimate in single-point stereo miking for your clients who demand the very best.

    Main Features

    • Vacuum tube circuitry provides high output and impedance matching
    • True stereophonic (Blumlein and M-S) recording from one coincident microphone and equal sensitivity from front or back of elements
    • High SPL capabilities and no distortion up to maximum SPL rating
    • Extremely low residual noise and very low magnetic leakage
    • Ribbon elements are not affected by heat or humidity
    • Consistent frequency response regardless of distance and absence of high frequency phase distortion
    • High efficiency, matching toroidal transformers

    The SF-24V is distinguished by extraordinary transparency, depth and midrange reach. It delivers gorgeous recordings of virtually all acoustic instruments. The Blumlein X-Y stereo image is wide and pinpoint accurate, and the mic can be rotated 45 degrees for M-S recording as well.

    The SF-24V comes in a protective carrying case containing:
    SF-24V in a beautiful custom made jewellers box
    Dedicated power supply
    RSM-24 shock mount
    20-foot stereo cable
    Owners manual and documentation

    Recommended applications: Orchestra, Small to Large Ensembles, Choir, Woodwind Sections, String Sections, Brass Sections, Drum Overhead, Drum Room, Piano, Percussion, Acoustic Instruments

    Warranty: Lifetime to the original owner. The tube warranty is 10 years. The ribbon elements are warranted for one year (first re-ribbon free within one year).

    A prominent Los Angeles engineer said 'The best way to describe the sound with the tube circuit involved is you start with an SF-24, add amazing midrange reach and transparency, sprinkle fairy dust all over it, and you get an SF-24V.' It's not the most technical explanation, but it does the job!

    Grammy winning scoring engineer Alan Meyerson (Angels & Demons, The Dark Knight, Pirates of the Caribbean) says 'The latest addition to Royer's tube ribbons, the SF-24V stereo, is astonishing. Unbelievable sound - superb imaging! Royer has hit another home run with the SF-24V.'
