Description
The 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 reasonably tolerant to shock and vibration, and performance 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 screen, such as the Royer PS-101, WS58 or equivalent, is highly
recommended for close-miking vocalists or certain types of percussion and wind instruments.
Applications
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
