The Royer SF-12 is a stereo coincident ribbon microphone that seamlessly blends high-quality audio performance with exceptional stereo separation and imaging. This modern ribbon design eliminates audible diffraction effects and cavity resonance, delivering a pristine audio experience. The SF-12 essentially comprises two matched ribbon microphones strategically positioned in a Blumlein configuration, providing optimal stereo performance. Each ribbon is aimed 45 degrees from the center, ensuring outstanding frequency response and negligible off-axis coloration.
The Royer SF-12 stands as a versatile and powerful tool for stereo and mono recording applications, delivering exceptional audio quality and flexibility.
Stereo Coincident Design: The SF-12 features two matched ribbon microphones arranged in a Blumlein configuration, capturing stereo audio with remarkable separation and imaging.
No Diffraction Effects: The modern ribbon design eliminates audible diffraction effects and cavity resonance, contributing to the microphone's transparent and natural sound reproduction.
Dual 1.8-Micron Ribbons: The SF-12 incorporates two 1.8-micron ribbons, each weighing approximately 1/3 milligram. These ribbons offer superb transient response, ensuring accurate capture of audio nuances.
Magnet/Pole Piece Structures: The ribbon transducers employ magnet/pole piece structures, producing a wide, uniform frequency response without substantial peaks or dips.
Ingot Iron Case: The microphone's case is crafted from ingot iron, forming part of the magnetic return circuit. This design minimizes leakage flux and enhances sensitivity within a compact package.
Y Adapter with Separate XLR Connectors: The SF-12 comes with an extension cable featuring a Y adapter that splits into separate 3-pin male XLR connectors labeled "Upper" and "Lower" for the upper and lower capsules of the microphone when held vertically.
True stereophonic (Blumlein and M-S) recording from one microphone.
High SPL capabilities.
No internal active electronics to overload or produce distortion up to maximum SPL rating.
Extremely low residual noise.
Ribbon element not affected by heat or humidity.
Absence of high frequency phase distortion.
Equal sensitivity from front or back of elements.
Consistent frequency response regardless of distance.
High efficiency, matching toroidal transformers.
Very low magnetic leakage
Natural Stereo Recordings: The SF-12 excels in creating "you-are-there" stereo recordings, faithfully capturing the instrument and the acoustic environment. Ideal for orchestras and ensembles.
Drum Overheads: Perfect for drum overheads, the SF-12 delivers powerful and dynamic drum tracks with exceptional stereo imaging and realism.
Jazz and Rock Recordings: In jazz settings, capturing the kit flat provides natural cymbals, tom-toms, and snares. For rock and pop, the SF-12 allows flexibility for EQ adjustments without introducing unpleasant distortion.
Brass and Woodwinds
Acoustic & Electric Guitars
Recording in Mono:
Phase Compatibility: The SF-12 exhibits excellent phase compatibility between its two sides, enabling the combination of channels for mono recording without introducing phase artifacts. (Stereo to Mono)
Mono Recording: Either side of the SF-12 can be used individually for mono recording, providing versatility in capturing a wide sound field.
