It is important to note that Royer ribbon microphones are known to be tough and durable. While all Royer’s are built to last a lifetime, the thicker ribbon element in our R-121 ribbon mic can take more abuse than the finer, somewhat more delicate ribbon element in your SF-1. - Page 4 3. The Royer model SF-1 requires no power supply and is safe to use on consoles with phantom microphone powering, provided that the cabling is properly wired. It should be noted that not all ribbon microphones are compatible with phantom-powering systems, so check the manufacturer’s recommendations before using other ribbon microphones.

If the microphone is to remain set-up on a stand when not in use, place a “mic sock” over it until it is to be used. Do not carry the microphone around without placing a “mic sock”...
- Page 6 For example: If the mic is rated at 300 Ohms (as Royer’s are), the preamp should have an input-impedance of at least 1500 Ohms. If the impedance of the preamp is too low, the microphone will lose low end and body.

Page 7: Equalization And Ribbon Microphones
With vintage ribbon microphones that employ large bulky magnet structures, the problem can be worse. Royer SF-1 and SF-12 microphones are designed to minimize the effects of unwanted radiation by integrating the transducer barrel as part of the magnetic return circuit. With this design, the barrel housing the transducer serves to complete the North-South magnetic return and neutralizes the effects of outside magnetic radiation. -

produce hum on their own. Unwanted noise (hum) can only come from an external source. Fortunately, there is a simple procedure that can be used to identify the source of the noise and eliminate it. Repositioning a dynamic and ribbon microphone is the number-one way to get rid of unwanted noise. -

2. Frequency response variation due to treble losses as a result of absorption and narrowing of the pattern at high frequencies-causing weakening of highs as the microphone is moved away from the sound source. 3. Rise in treble response on-axis due to diffraction. 4. -

Typical relationship of microphone distance to frequency response for ribbon-velocity bi- directional microphone. Another area where proximity effect can be turned to an advantage is in making things sound “more real than real.” For example, many voices and certain musical instruments produce fundamental frequencies within the bass range (below 150HZ or so) but the fundamentals are weak. - Page 11 piano at a distance of one foot to several feet, depending on taste. A more direct up front sound will be achieved when the microphone is placed closer to the soundboard. For capturing a piano in stereo, place the microphones apart, one over the bass strings and the other over the high strings.

- Page 15 them. The new designs were compact, rugged and sensitive. It wasn’t long before the television industry embraced these new designs. Radio followed the trend shortly afterward. Further technological development of ribbon microphones was considered unnecessary and the beloved ribbon soon faded into obscurity. It is a fate reminiscent of that of the vacuum tube when transistors hit the scene.
