Two Matched Ribbon Mics in One Body!

NEWS: Royer Labs has been given a GRAMMY award for their outstanding ribbon mics! In the words of the Academy, these mics "were revolutionary and moved the art of recording forward."

The Royer 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.

Royer SF-12 stereo ribbon microphone at a Glance:
  • Two matched ribbon mics in one body
  • Superb transient response from low-mass ribbons
  • Stereo recording at its finest for any application

Two matched ribbon mics in one body
The Royer SF-12 is actually two matched ribbon microphones placed one above the other and fixed at a 90-degree angle. This arrangement allows for Blumlein and M-S recording with one microphone, as well as excellent monaural compatibility when summing the two ribbon elements to mono. The SF-12's frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible. The Royer SF-12's extension cable comes with an adapter which splits into separate left and right XLR connectors, labeled "upper" and "lower."

Superb transient response from low-mass ribbons
The Royer SF-12's two 1.8-micron ribbons are of pure (99.99%) aluminum and provide superb transient response due to their low mass. Each of the Royer SF-12's two ribbon transducers incorporate "cross-field" motor assemblies (patent pending) which are comprised of four powerful Neodymium magnets and Permendur iron pole-pieces. This crossfield design delivers excellent high frequency response due to the extremely short path between the front and rear (sides) of the ribbon elements. The microphone's 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.

Stereo recording at its finest for any application
Trust the Royer SF-12 to provide flawless reproduction of any stereo source. It's especially well suited to capture large sections and ensembles with outstanding clarity and imaging. The SF-12 is ideal for percussion instruments, acoustic guitars, and other plucked strings

Royer SF-12 Recommended Applications:
  • Stereo & distance miking
  • Choir, orchestra, string sections
  • Drum overheads, room miking
  • Percussion instruments
  • Brass instruments, horn sections
  • Woodwind instruments
  • Stereo acoustic piano, harp
  • Acoustic guitar, mandolin, stringed instruments
Royer SF-12 stereo ribbon mic Features:
  • True stereophonic (Blumlein and M-S) recording from one microphone
  • No internal active electronics to overload or produce distortion up to maximum SPL rating.
  • Extremely low residual noise
  • Ribbon elements unaffected by heat or humidity
  • Absence of high frequency peaks, "ringing" and phase shifts
  • Equal sensitivity from front and back of elements
  • Very low magnetic leakage
  • High efficiency toroid matching transformers and gold plated output connector
The Royer SF-12 Stereo Ribbon Microphone is clearly a winner!

a balanced stereo mic

I had AT4050ST for overhead drums miking, it was amazing. but after compare SF-12 with it side by side, I have to say Royer is the winner. I run it with my RME XTC, gain 40 it already rocks, balanced and musical melody. it's all about the mid range, and the low end is just right. try before buy, or you may miss a magic! thanks to my manager Dennis Konicki, he's so patient and never let me down.

Wow! Drum Overhead and Acoustic mic magic!

I wanted a mic that would give me the best possible sound for acoustic instruments and make a great drum overhead. The Royer SF-12 does both with ease. My very first recording with this mic on an acoustic guitar made it obvious I was going to love it! Today I used the SF-12 for a drum overhead, put a MA-200 about 10 inches from the Kick drum port and a SM-57 on the snare. The SF-12 captured a very clean and realistic full bodied drum sound. I dressed up the sound by adding a little of the Kick drum mic and the snare mic, simply amazing. This ribbon really does take eq wonderfully, the nice thing is that it is easier to get the sound I want now. It is worth the money if you can afford it. You will need a high gain, very clean preamp, but you will like the results.

Sweetwater Advice

I haven't found a more natural-sounding mic than the Royer SF-12.

Alex Arnold

The Royer SF-12 is a fantastic ribbon microphone! The SF-12 is actually a stereo microphone, and as some people have put it, actually two SF-1's combined. It is a great value for the money, and is a microphone no studio would want to be without. In my experience of using it, I have found that it sounds great on a variety of instruments. I have used it on drums and the result is stunning; the captured warmth of the SF-12 translates beautifully even through an Mbox! This mic sounds not only great on drums, but on vocals, and guitar. I did some A/B comparisons between the Royer SF-12 and Audio Technica's AT3035, and while the AT3035 is a decent mic, the SF-12 blew it out of the water! The big difference is that the AT3035 has a slight tendency to sound 'tinny,' while the SF-12 sounds big and warm and nice in the lower end. All in all the Royer SF-12 would be a valued treasure to any home or commercial studio.
