Product Details
The 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 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 Electronics The 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 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 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 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 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. Patented Offset Ribbon Technology The R-122’s proprietary offset ribbon transducer (Patent Number: 6,434,252) positions the ribbon element closer to the front (logo) side of the microphone than the rear. This arrangement gives the ribbon more room to move within the prime magnetic field while maintaining full frequency response during high SPL recordings. It’s an integral piece of the magic of all Royer R-series microphones.
