The Royal Labs R-122V is the pinnacle of our R-Series line, a world class tube ribbon microphone exhibiting unparalleled richness, depth and detail, particularly in the midrange frequencies. With a lushness that has to be heard to be truly appreciated, the Royal Labs R-122V offers the ultimate in ribbon microphone performance for those who insist on the very best.
The Royal Labs R-122V takes the Royer-pioneered concept of active ribbon microphone technology to an unprecedented level by incorporating vacuum tube electronics into the same proven transducer system used in the venerable R-121 and Royal Labs R-122 ribbon microphones. The high operating voltage of the vacuum tube provides headroom far beyond that available from a standard phantom power supply. Sonically this translates into unmatched clarity, detail and airiness, along with the ability to handle brute SPL levels without flinching.
The Royal Labs R-122V's head amplifier consists of a low-noise, triode-connected military grade 5840 vacuum tube. Designed for a wide range of applications, the Royal Labs R-122V offers superb transient response and the drive capabilities only a vacuum tube head amplifier can provide. The circuit is devoid of typical vacuum tube coloration.
The Royal Labs R-122V's triode-configured cathode follower circuitry enables the microphone to drive long cable runs without sonic degradation or high-frequency loss. This capability is further enhanced by the R-122V's dedicated power supply, which provides ample current to the vacuum tube electronics. Induced noise is virtually eliminated by the microphone's fully balanced output, which is electrically isolated with a special purpose Jensen output transformer.
Like our phantom powered R-122, the Royal Labs R-122V has far more level than non-powered ribbon microphones and its impedance matching circuitry places a perfect load on the ribbon element at all times. This allows the use of a wide variety of mic preamps without concern for gain and impedance matches, two critical issues with ribbon microphones. All of the Royal Labs R122V's increased output comes from its large, specially designed toroidal transformer, so there is no additional noise associated with the microphone's higher output.
