Description

The Royer SF-12 is a passive stereo ribbon microphone designed to deliver remarkably natural, immersive recordings from a single, elegant body. Using two matched ribbon elements in a precise Blumlein configuration, it captures a lifelike stereo image with exceptional depth, realism and phase coherence, making it a go-to choice for engineers who want a true “you are there” sound without complex multi-mic setups. At its heart, the SF-12 is all about faithful, musical reproduction. Its ultra-thin 1.8-micron aluminium ribbons respond effortlessly to transients, while the symmetrical figure-8 polar patterns maintain a consistent frequency response regardless of angle or distance. The result is a smooth, open sound with negligible off-axis coloration, ideal for everything from orchestras and choirs to drum overheads, acoustic instruments and room ambience. Because the SF-12 is a coincident stereo design, you get superb stereo separation and imaging without the phase issues that can plague spaced pairs. The two ribbon motors share a carefully engineered magnet and pole-piece structure, housed in an ingot iron body that forms part of the magnetic circuit. This delivers high sensitivity in a compact, robust package with very low magnetic leakage, so you can place the mic confidently in demanding studio and live environments. Engineers value the SF-12 not only for its stereo performance but also for its flexibility. It excels as a single-point stereo solution for ensembles and rooms, yet each side can also be used individually as a mono ribbon microphone. Its outstanding phase compatibility means you can sum both channels to mono without introducing unwanted artefacts, making it a powerful tool when you need to move between stereo and mono mixes while preserving tonal integrity. Uncanny Stereo Realism The SF-12’s coincident Blumlein configuration captures a highly accurate stereo field with precise localisation and natural depth. By placing the microphone where the source sounds best in the room, you can record not only the instrument or ensemble but also the acoustic space itself, delivering a convincing, three-dimensional listening experience. Modern Ribbon Design Using two 1.8-micron aluminium ribbon elements, each weighing around one third of a milligram, the SF-12 offers superb transient response and a wide, uniform frequency range. The absence of audible diffraction effects or cavity resonances keeps the sound smooth and musical, with minimal off-axis coloration and no harsh high-frequency artefacts. Phase-Coherent Mono Compatibility Excellent phase compatibility between the two ribbon elements allows you to sum the SF-12’s outputs to mono without introducing phase problems. This is particularly useful when capturing wide sources that may need to sit in a mono mix, or when recording performers who move around the sweet spot, ensuring consistent, stable tone. High SPL Handling and EQ-Friendly Response The SF-12 can comfortably handle high sound pressure levels, making it ideal for drum overheads, brass, percussion and other powerful sources. With no internal active electronics to overload and virtually no self-distortion, the microphone responds extremely well to equalisation, allowing you to boost frequencies confidently without unpleasant artefacts. Key Features True Stereo from a Single Microphone – The SF-12 houses two matched ribbon elements in a coincident configuration, enabling Blumlein and mid-side techniques from one body. This simplifies setup, reduces phase issues and delivers a coherent, natural stereo image that translates beautifully on speakers and headphones. Symmetrical Figure-8 Polar Patterns – With equal sensitivity front and back, the SF-12’s figure-8 patterns maintain a consistent frequency response regardless of angle. This gives you predictable results when positioning the mic around ensembles, drum kits or in rooms, and helps capture a balanced blend of direct sound and ambience. Ultra-Thin 1.8-Micron …
