Royer SF-12

Passive ribbon microphone

The Royer SF-12 stereo coincident ribbon microphone is one of the finest devices of its kind, combining high quality audio performance with outstanding stereo separation and imaging.

The Royer SF-12 is uncanny for creating ‘you-are-there’ stereo recordings that capture not only the instrument being recorded, but, depending on positioning, the acoustic environment as well. It is a modern ribbon design with no audible diffraction effects or cavity resonance. An SF-12 is actually two matched microphones placed one above the other, each aimed 45 degrees from center. The frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible. The SF-12's extension cable comes with a Y adapter that splits into separate 3-pin male XLR connectors. The two connectors are labeled Upper and Lower for the upper and lower capsules of the microphone (when held vertically).

The two 1.8-micron ribbons are of pure aluminum (99.99%), each weighing approximately 1/3 milligram and producing superb transient response. The magnet/polepiece structure allows a wide uniform frequency range with no substantial peaks or dips. The case is ingot iron and forms part of the magnetic return circuit, an effective system with low leakage flux which accounts for the relatively high sensitivity in a trim package.
