Matched ribbon microphones, active tube circuitry, figure-8 pattern, enhanced high-frequency response, high SPL capability, low noise floor, includes shock mounts and case
The SF-24V vacuum tube stereo ribbon microphone is the pinnacle of our SF-series stereo microphones. The sound pickup is lush, smooth and natural, with outstanding stereo imaging and superb transient response. The tube electronics provide increased midrange reach, unmatched clarity and detail, and an airiness previously unheard of in ribbon mics. Utilizing the same proprietary tube electronics as in our TEC Award winning R-122V ribbon microphones, the SF-24V delivers the ultimate in stereo ribbon miking for the true connoisseur of recorded sound.
The SF-24V's independent tube circuits provide an output level of -38 dB, suitable for use with any professional preamplifier. With self-noise of lower than 18 dB, the SF-24V's ultra-quiet operation is suitable for the most demanding classical and acoustic recording applications.
Like an SF-12, the SF-24V is actually two matched ribbon microphones, placed one above the other in a coincident pair, each 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.
The Electronics
The R-122V's head amplifier consists of a low-noise, triode-connected military grade 5840 vacuum tube. Designed for a wide range of applications, the R-122V offers superb transient response and the drive capabilities only a vacuum tube head amplifier can provide. The circuit is devoid of typical vacuum tube coloration.
The R-122V's triode-configured cathode follower circuitry enables the microphone to drive long cable runs without sonic degradation or high-frequency loss. This capability is further enhanced by the R-122V's dedicated power supply, which provides ample current to the vacuum tube electronics. Induced noise is virtually eliminated by the microphone's fully balanced output, which is electrically isolated with a special purpose Jensen output transformer.
Like our phantom powered R-122, the R-122V has far more level than non-powered ribbon microphones and its impedance matching circuitry places a perfect load on the ribbon element at all times. This allows the use of a wide variety of mic preamps without concern for gain and impedance matches, two critical issues with ribbon microphones. All of the R122V's increased output comes from its large, specially designed toroidal transformer, so there is no additional noise associated with the microphone's higher output.
Patented Offset Ribbon Technology
The R-122's proprietary offset ribbon transducer (Patent Number: 6,434,252) positions the ribbon element closer to the front (logo) side of the microphone than the rear. This arrangement gives the ribbon more room to move within the prime magnetic field while maintaining full frequency response during high SPL recordings. It's an integral piece of the magic of all Royer R-series microphones.
