Royer Labs R-122V Vacuum Tube Active Ribbon Microphone, from Royer

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.

Recording with the R-122V is a revelation. The realism, warmth, openness and detail have to be experienced to be believed. Asked to describe the R-122V's sound, a prominent Los Angeles based engineer said "You combine what's best about the R-121 and R-122 into one mic, sprinkle fairy dust all over it, and you have an R-122V." Not technical, but well put.

In classical recordings, the R-122V is used on woodwinds, strings, percussion, brass, room, even the Decca Tree. They make excellent spots. If condensers are used as spots, R-122V's at a distance (2 to 6 feet) add dimensionality, warmth and size to the recording. The microphone has ample gain to capture even the quietest instruments, and its low output impedance allows for long cable runs with no signal degradation.

On applications like electric guitars and drums, the "reach" and lushness of the R-122V helps capture drop-dead tracks.

The R-122V is the pinnacle of Royer's 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 R-122V offers the ultimate in ribbon microphone performance for those who insist on the very best.

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 the 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.

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.

At distances of three feet and closer, the back of the R-122V records slightly brighter than the front side. This can be extremely useful when recording acoustic guitars, vocals, and other sound sources for which you desire a slightly brighter response.
