Active Ribbon Technology
Royer Labs pioneered the first active ribbon microphones with
the introduction of the R-122 in 2002. The R-122 is a solid-state
microphone that operates from standard 48-volt simplex power.
The development of that microphone was the result of several
years of effort that actually began with our developing several
vacuum tube versions first. The tube circuitry research was crucial
to the development of the specialized audio transformer used in
the R-122, and a necessary step for the development of our solid-
state, phantom powered ribbon microphones. Technically speaking,
Royer vacuum tube ribbon microphones predate our phantom
powdered models, which are now industry standards.
The heart of the R-122V (and all Royer Active Series microphones)
is a proprietary system consisting of a specially designed toroidal
transformer and electronic buffering stage. These work together
as a single unit to provide excellent frequency response, very low
noise, very low distortion and very high SPL handling without
the use of pads. The system gives the R-122V an output level
comparable to that of condenser microphones, and its buffer stage
provides a low impedance output while presenting a perfect
impedance load to the ribbon element. Non-powered ribbon
microphones suffer substantially degraded frequency response
and lowered sensitivity when they are paired to a preamp with
too low of an input impedance. With the R-122V’s vacuum tube
circuitry, the microphone’s frequency response and output are
much less affected by variations in the input impedance of the
following preamp.
Sonically, the R-122V differs from the non-powered R-121 and
the phantom powered R-122 in a few subtle, but significant, ways.
Due to the extra iron in the R-122V’s much larger transformer,
low-end frequencies sound slightly tighter and more focused than
with the R-121 (the R-122 also utilizes this special Royer designed
transformer). Compared with that of the R-121, the transient
response of the R-122 and R-122V is faster, giving the sense of
a more open high-end response.
Sonically, the R-122V is set apart by its increased midrange reach
