Stereo Coincident Ribbon Microphone

The Royer/Speiden 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. 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. TheSF-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.
