The SF-12 stereo coincident ribbon microphone combines high quality audio performance with outstanding stereo separation and imaging. It is a modern ribbon design with no audible diffraction effects or cavity resonance. An SF-12 is actually two matched ribbon microphones placed one above the other; each aimed 45 degrees from center in the classic Blumlein configuration. The frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible.The SF-12 utilizes two 1.8-micron ribbons, each weighing approximately 1/3 milligram and producing superb transient response. The two ribbon transducers are magnet/pole piece structures that produce a wide, uniform frequency response 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. The SF-12's extension cable comes with 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).Royer Labs SF-12 Features 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.

...been learning so much from this forum for years. My humble rig, during a recent orchestral recording at Stony Brook University: Royer SF12 main Blumlein on Manfrotto stands CMC6 MK2 outriggers, half way between center mics and last stand on strings, also on Manfrotto's KM184's wood winds in NOS Joly modded Oktava's MC012 cards in NOS percussion Earthworks QTC1 timps,...

Anything better than km184s/84s for OHs?!

I actually prefer the Mercenary KM69 (though no longer available new) to either of the Neumanns for cymbal mics. I often use a Royer SF12 nowadays with a little shelf at 16k for OH.
