The Royer Labs model SF-1 is an ultra compact bi-directional
(figure-eight)
velocity type
ribbon microphone designed for professional applications. The figure-eight pick-up
pattern allows the SF-1 to be addressed from either side with equal sensitivity. The
in-
phase
signal is achieved when the microphone is addressed from the front, indicated by
the “ROYER” logo.
The SF-1 is very tolerant to shock and vibration, and is unaffected by changes in
temperature or humidity. However, ribbon microphones are sensitive to direct blasts of
air and the SF-1 is no exception to this rule. Discretionary use of a windscreen or pop-
filter, such as the WS58, PS-100 or equivalent is highly recommended for situations such
as close miking, especially with vocalists or certain types of percussion and wind
instruments.
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. The SF-1 can handle over 130 dB SPL, while the R-121 can handle over 135
dB SPL. Please be aware of this as you use your SF-1. Handled with care, it will be
many years before you need to re-ribbon your microphone (ribbons can last indefinitely if
not abused.)
