Royer Labs Now Shipping SF-24 Microphone

New Phantom-Powered Stereo Ribbon Microphone (August 06, 2004)

Royer Labs, a leading manufacturer of high quality ribbon microphones, is now shipping its new SF-24 Phantom Powered Stereo Ribbon Microphone. Designed as a premium instrument for stereo and distance miking applications, the SF-24 provides extremely natural, uncolored recordings of choirs, pianos, harp, stringed instruments, and is particularly well-suited to miking large ensembles such as an orchestra or the various sections within?including brass and woodwinds. The SF-24 is also perfect as a single-point stereo overhead drum and percussion mic.

Like Royers popular SF-12 stereo ribbon microphone, the new SF-24 delivers high quality audio performance with outstanding stereo separation and imaging. But the SF-24 represents a significant improvement for many ambient and critical applications, due to the inclusion of Royers exclusive active electronics system for ribbon microphones. Featuring two fully balanced, discrete head amplifier systems utilizing ultra-low noise FETs, each delivering an output sensitivity rating of 38 dB, the SF-24s sensitivity is on par with that of phantom powered condenser microphones?facilitating use with any preamplifier with average gain characteristics. The impedance matching circuitry provides optimum impedance to the ribbon elements, preventing overdamping of the elements and assuring consistent performance. This capability translates to ultra-quiet operation with self-noise lower than 18 dB, making the SF-24 ideal for recording quiet sound sources with enough gain to drive any recording medium.

Housed in an ingot iron case that forms part of the magnetic return circuit, the SF-24 consists of two matched ribbon microphones placed one above the other, each aimed 45 degrees from center in the classic Blumlein configuration. The magnet/polepiece structure of each ribbon transducer allows a wide, uniform frequency range with no substantial peaks or dips, and the two 1.8-micron pure aluminum ribbons produce superb transient response. Frequency response is excellent, regardless of the angle of sound striking the ribbons, with negligible off-axis coloration. The SF-24's cable incorporates a Y adapter that splits into separate 3-pin male XLR connectors labeled "Upper" and "Lower" for the instruments upper and lower capsules. The SF-24s package also includes a shock mount, a mic sock, and an elegant protective case.

?The SF-24 represents an unheard of level in ribbon microphone performance, says John Jennings, Royers VP of Sales and Marketing. ?With its ability to accurately capture the most subtle performance nuances from a distance, the SF-24 is perfectly suited for orchestral and small ensemble recording. With the gain and impedance matching issues out of the way, the SF-24 greatly expands on the SF-12s stereo recording capabilities and becomes a drop-dead gorgeous mic for critical, lower SPL applications. And its smoking on drums and percussion.
