The R-122V is the world's first commercially produced tube ribbon microphone and the pinnacle of Royer's R-Series line – pairing the proven ribbon transducer from the R-121 and R-122 with a vacuum tube output stage that delivers warmth, depth, and headroom unavailable from any phantom-powered ribbon design.\u003c\/p\u003e\n\n  \u003ch3\u003eTube in the Ribbon Signal Path – What It Actually Changes\u003c\/h3\u003e\n  \u003cp\u003eThe output stage is built around a JAN mil-spec 5840W pentode wired in triode configuration, operating at a 135 V DC plate supply – headroom that no phantom-powered circuit can match. The result is a sensitivity of -36 dBV\/Pa with self-noise below 18 dB, and an output approximately 25 dB hotter than a passive R-121, while retaining the smoothness and detail characteristic of the best tube condensers. The active circuitry provides optimal impedance to the ribbon element under any load condition, eliminating the damping problem caused by low-impedance preamp inputs. A Jensen 8:1 output transformer delivers a fully balanced, electrically isolated output capable of driving any preamplifier and long cable runs without signal loss.\u003c\/p\u003e\n\n  \u003ch3\u003eRibbon Transducer and Figure-8 Pattern – Studio and Stage\u003c\/h3\u003e\n  \u003cp\u003eThe 2.5-micron aluminium ribbon at 99.99% purity operates in a neodymium magnet field within Royer's patented offset-ribbon flux frame, which reduces stray magnetic radiation. The figure-8 polar pattern delivers equal sensitivity from both sides of the capsule, opening up MS, mid-side with a cardioid, and classic two-mic stereo configurations. The rear axis has a slightly brighter character within approximately three feet, which can be exploited deliberately on acoustic sources. The Matched Pair designation means factory-selected units with closely matched sensitivity and frequency response – a necessary condition for a coherent stereo image.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eWorld's first commercial tube ribbon microphone – limited production, hand-built in Burbank CA\u003c\/li\u003e\n    \u003cli\u003eJAN mil-spec 5840W tube in triode configuration – headroom far beyond phantom power supply limits\u003c\/li\u003e\n    \u003cli\u003e2.5-micron aluminium ribbon, 99.99% purity, neodymium magnets in patented flux frame\u003c\/li\u003e\n    \u003cli\u003eOutput approximately 25 dB hotter than passive R-121 with low self-noise maintained\u003c\/li\u003e\n    \u003cli\u003eJensen 8:1 output transformer – symmetrical, fully balanced output signal\u003c\/li\u003e\n    \u003cli\u003eFigure-8 polar pattern – equal sensitivity both sides, rear axis slightly brighter in close field\u003c\/li\u003e\n    \u003cli\u003eSPL handling above 135 dB @ 20 Hz – electric guitar, cymbals, and drums without issue\u003c\/li\u003e\n    \u003cli\u003eFactory Matched Pair – selected for stereo and MS use\u003c\/li\u003e\n    \u003cli\u003eDedicated power supply included, military-grade locking XLR cable set, RSM-1 shockmount, wooden storage case\u003c\/li\u003e\n    \u003cli\u003eLifetime warranty to original owner; tube warranted 10 years; first re-ribbon free of charge\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eAcoustic operating principle: electrodynamic pressure gradient with vacuum tube electronics\u003c\/li\u003e\n    \u003cli\u003eVacuum tube: JAN mil-spec 5840W pentode in triode configuration\u003c\/li\u003e\n    \u003cli\u003ePolar pattern: figure-8\u003c\/li\u003e\n    \u003cli\u003eGenerating element: 2.5-micron aluminium ribbon\u003c\/li\u003e\n    \u003cli\u003eMagnets: rare earth neodymium\u003c\/li\u003e\n    \u003cli\u003eFrequency response: 30–15,000 Hz ±3 dB\u003c\/li\u003e\n    \u003cli\u003eSensitivity: -36 dBV\/Pa ±1 dB\u003c\/li\u003e\n    \u003cli\u003eSelf-noise: \u0026lt;18 dB\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 200 Ω, balanced\u003c\/li\u003e\n    \u003cli\u003eRated load impedance: 1 kΩ\u003c\/li\u003e\n    \u003cli\u003eMaximum SPL: \u0026gt;135 dB @ 20 Hz\u003c\/li\u003e\n    \u003cli\u003ePower requirements: plate 135 V DC @ 2 mA, filament 6 V DC @ 150 mA (dedicated power supply)\u003c\/li\u003e\n    \u003cli\u003eDimensions: 206 mm L x 25 mm W\u003c\/li\u003e\n    \u003cli\u003eWeight: 300 g (10.9 oz)\u003c\/li\u003e\n    \u003cli\u003eFinish: dull satin nickel \/ matte black chrome optional\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Royer Labs","offers":[{"title":"Default Title","offer_id":53989019386193,"sku":"28592","price":8781.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/RoyerLabsR-122VTubeVersion-MatchedPair1.jpg?v=1781093759","url":"https:\/\/wrdtunes.com\/fr\/products\/royer-labs-r-122v-tube-version-matched-pair","provider":"Wired Tunes","version":"1.0","type":"link"}
