The Royer Labs model R-121 is a compact bi-directional (figure-eight) velocity type
ribbon microphone designed for professional applications. The figure-eight pick-up
pattern allows the R-121 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 R-121 is tolerant of shock and vibration, and is unaffected by changes in temperature
or humidity. However, ribbon microphones are somewhat more sensitive to direct blasts
of air, and the R-121 is no exception to this rule. Discretionary use of a windscreen or
pop-filter, such as the PS-100, PS-101, WS58 or equivalent is highly recommended for
situations such as close miking, especially with vocalists or certain types of percussion
and wind instruments.

The Royer Labs model R-121 is a versatile microphone and is ideally suited for many
critical recording applications. Its smooth frequency response characteristics and ability
to capture detail make it a fine choice for many instruments, as well as for general
broadcast applications. Its gentle low-frequency proximity effect makes it especially
useful for announcers and vocalists. Female vocalists often benefit from the R-121’s
ability to capture high frequencies without distortion or edginess. Orchestral instruments
are captured in a natural sounding way and free from microphone-induced “hype”. The
R-121 has exceptionally smooth high frequency characteristics. Phase-related distortion
and irregular frequency peaks are conspicuously absent. Theater organs and electric guitar
amplifiers sound big and fat, without unnatural coloration, when reproduced with the R-
121. These features make the R-121 ribbon microphone an ideal choice for strings,
