Description
The   R-122V   is   a   compact,   active,   bi-directional   (figure-eight)   velocity   type   tube   ribbon 
microphone designed for professional applications. The figure-eight pickup pattern allows the 
R-122V 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-122V is reasonably tolerant of 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-122V  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-122V 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 vocalists and announcers. 
Female vocalists often benefit from the R-122V’s ability to capture high frequencies without 
distortion or edginess. Orchestral instruments are captured in a natural-sounding way, free from 
microphone-induced   “hype.”   The   R-122V   has   exceptionally   smooth   high   frequency 
characteristics   and   is   devoid   of   microphone   induced   ringing.   Phase-related   distortion   and 
irregular frequency peaks are conspicuously absent. These features make the R-122V vacuum 
tube   ribbon   microphone   an   ideal   choice   for   strings,   woodwinds,   percussion   and   amplified 
instruments. Theater organs and electric guitar amplifiers sound big and fat, without unnatural 
coloration, when recorded with the R-122V. Acoustic pianos can be captured accurately without 
the comb-filtering effects associated with condenser microphones. 
Ribbons in the Digital World
Digital recordings benefit greatly from the properties inherent in ribbon microphones. Since A to 
D converters   cannot  distinguish   between  the  sound  source  being   recorded  and   the complex 
distortion   components   often   associated   with   condenser   microphones,   they   sometimes   have 
difficulty tracking the signal, resulting in ringing and edgy-sounding tracks. With quality ribbon 
microphones, ringing is almost nonexistent due to the ribbon’s lack of distortion artifacts and 
high frequency peaks. A to D converters have less difficulty tracking the ribbon-generated signal, 
resulting in very smooth digital recordings free of microphone-related edginess.
