Royer Labs is a microphone company that some consider to be one of the foremost manufacturers of ribbon microphones. The reasons most often cited for this opinion is that Royer has combined the traditional warmth of vintage ribbon microphones with modern output levels. While older ribbon microphones had a great sound, the ribbons were weak and would break easily. Royer microphones, however, are still strong enough to be placed in front of electric guitar amps, a placement that certain older ribbons could not have weathered.
David Royer designed his first ribbon microphone in 1997 and started the company that bears his name one year later. When that first microphone, the R-121, was released, it received positive reviews from all the major recording magazines.
The R-121 Ribbon microphone contained two innovations that delivered the performance levels necessary for professional studio use. Neodymium magnets produce a much stronger magnetic field than the AlNiCo magnets used by vintage designs, raising the microphones's sensitivity. High-grade output transformers raise the microphone's signal-to-noise ratio.
The R-121 is also known for its use of Royer's patented "offset ribbon" design, in which the placement of the aluminum ribbon allows it to withstand louder sources from the front of the microphone, as well as giving the microphone a slightly different voicing from front to back.
