Our R-series mics have a patented offset ribbon design, created to help them do a better job of handling high SPL’s. Because the ribbon is in a different physical space when you use the back side of the mic, there is a slight tonal difference between the two sides (see Recording With The Back Side).
The best way to explain the differences between R-series mics (R-121, R-122 MKII, R-122V) and SF-series mics (SF-12, SF-24, SF-1) is to take a look at their ribbon transducers (the transducer is the magnetic frame or assembly that the ribbon element is housed in). This is the R-121 transducer (also used in R-122 MKII’s and
An SF-12 cannot be upgraded to SF-24 specification. Although the SF-12 and the SF-24 share the same transducer assemblies and have similar sonic characteristics, they are two very different microphones. The impedance matching transformers that are integral to each model are very different electrically and physically. The SF-24’s active electronics will not work with the
Yes, in two different ways. The SF-12 sums to mono extremely well, so you can combine the outputs of both channels into one channel for a mono track. Or, being that an SF-12 is made up of two identical mono ribbon elements, positioned one above the other, you can use either side of the SF-12
No. The magnet system and ribbon elements of SF-12’s and R-121’s are entirely different, and the response and recommended uses for each mic are somewhat different. In my opinion, the SF-12 has a slightly smoother response and somewhat better figure-8 pattern. Did this answer your question?Yes NoAdditional CommentsSend Feedback
Yes. The SF-12 has two ribbon elements spaced at 45 degrees from center, which is the classic Blumlein configuration. Being that the SF-12’s ribbons are positioned at 90 degrees apart (X-Y position) you can also rotate the SF-12 by 45 degrees and use it for M-S recording. For a detailed explanation of how this works,
Some preamplifier designs are prone to developing internal ground loops when used in conjunction with stereo microphones such as the Royer SF-12. A ground loop manifests itself as unwanted noise, buzz or hum (usually 60Hz or 120 Hz). The problem may be more apparent with lower output microphones such as dynamics or passive ribbons because
The R-122 MKII can handle SPLs of up to 135db, which is really loud! At high levels, care must be taken in placement – a 45 degree angle is helpful. Also, mic pre overload becomes a possibility, due to the high output of the R-122 MKII’s active circuitry (see When I use my R-122 MKII
The R-122 MKII is a high output microphone. When used on loud sources, the possibility exists of overloading the input of your microphone preamp. An easy fix is to use an inline attenuator between the mic and the input of the mic pre. Inline attenuators, such as those made by Switchcraft, AudioTechnica, Shure and ProCo,
Phantom power is actually required for operation of the R-122 and will not damage it in any way. For more information visit Ribbon Mics and Phantom Power. Did this answer your question?Yes NoAdditional CommentsSend Feedback
