The 1.8-micron aluminum ribbon at 59.7 mm × 4.7 mm, the transformer, and the 16.5 Hz resonant tuning are identical to the R44C; the motor uses modern design techniques with stronger but smaller permanent magnets. The result is classic RCA 44 tonality with extended top-end response, reduced proximity effect, and better mechanical vibration isolation in a body weighing 1.36 kg instead of the R44C's 3.6 kg.\u003c\/p\u003e\n\n  \u003ch3\u003eBig Ribbon and 16.5 Hz Tuning — Dynamics and Low End Without Resonance\u003c\/h3\u003e\n  \u003cp\u003eRibbon resonant tuning below the audible band (16.5 Hz) means the R84 exhibits no mechanical resonances in the 20 Hz–20 kHz range — a common problem with shorter ribbon elements and condenser capsules that show audible response peaks. In practice this translates to smooth, coherent low-frequency reproduction of drums and bass instruments, accurate transient attack without exaggeration, and a high-frequency rolloff that avoids the harshness of condenser designs. Proximity effect is present but less pronounced than in the R44C — at 12–24 inches the R84 holds a tonal balance comparable to what the R44C delivers at roughly 3 feet. This makes it practical for close-miking (amplifiers, brass, percussion) as well as medium-distance applications (vocals, acoustic instruments, strings). Maximum SPL of 165+ dB handles speaker-level signals from cranked amplifiers without any external attenuator.\u003c\/p\u003e\n\n  \u003ch3\u003ePassive Signal Path and Preamp Requirements\u003c\/h3\u003e\n  \u003cp\u003eThe R84 requires no phantom power and is not recommended with it — 48 V can damage the ribbon if the cable or preamp circuit is unbalanced or develops a fault. Sensitivity of 2.5 mV\/Pa (–52 dBV) is higher than the R44C (1.8 mV\/Pa) and substantially higher than the Coles 4038 (0.5 mV\/Pa), but still demands a preamp with at least 60 dB of gain and a load impedance above 1.2 kΩ for full frequency response. For loud sources, any console preamp presenting above 5 kΩ is adequate; for quiet sources or distance recording, AEA's dedicated ribbon preamps are recommended. The microphone ships with a 3-meter captive cable terminating in XLR-3M, a shockmount, and a foam-lined carrying case.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003ePassive Big Ribbon — same ribbon element, tuning (16.5 Hz), and transformer as the R44C\u003c\/li\u003e\n    \u003cli\u003eModern motor with stronger magnets — extended HF and reduced proximity effect vs. R44C\u003c\/li\u003e\n    \u003cli\u003ePolar pattern: figure-8 (bidirectional)\u003c\/li\u003e\n    \u003cli\u003eMax SPL: 165+ dB (1% THD harmonic distortion \u0026gt;1 kHz)\u003c\/li\u003e\n    \u003cli\u003eSensitivity: 2.5 mV\/Pa (–52 dBV) into unloaded circuit\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 270 Ω nominal\u003c\/li\u003e\n    \u003cli\u003eRecommended load impedance: ≥1.2 kΩ\u003c\/li\u003e\n    \u003cli\u003ePhantom power: not required or recommended\u003c\/li\u003e\n    \u003cli\u003eSmooth top-end response — extended and controlled vs. R44C, no condenser harshness\u003c\/li\u003e\n    \u003cli\u003eOff-axis rejection: –35 dB at 90°\/270° (both axes)\u003c\/li\u003e\n    \u003cli\u003e3 m captive cable, XLR-3M connector\u003c\/li\u003e\n    \u003cli\u003eAccessories: shockmount, 3 m cable, foam-lined carrying case\u003c\/li\u003e\n    \u003cli\u003eDimensions: 295 mm (H) × 99 mm (W) × 64 mm (D); weight: 1.36 kg with cable\u003c\/li\u003e\n    \u003cli\u003eHandmade in Pasadena, California, USA\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eOperating principle: pressure gradient transducer (passive)\u003c\/li\u003e\n    \u003cli\u003ePolar pattern: figure-8 (bidirectional)\u003c\/li\u003e\n    \u003cli\u003eFrequency range: \u0026lt;20 Hz – \u0026gt;20 kHz\u003c\/li\u003e\n    \u003cli\u003eMax SPL: 165+ dB (1% THD \u0026gt;1 kHz)\u003c\/li\u003e\n    \u003cli\u003eSensitivity: 2.5 mV\/Pa (–52 dBV) into unloaded circuit\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 270 Ω nominal\u003c\/li\u003e\n    \u003cli\u003eRecommended load impedance: ≥1.2 kΩ\u003c\/li\u003e\n    \u003cli\u003ePhantom power: not required or recommended\u003c\/li\u003e\n    \u003cli\u003ePolarity: Pin 2 + for positive pressure at front\u003c\/li\u003e\n    \u003cli\u003eOff-axis rejection: –35 dB at 90°\/270° (horizontal and vertical)\u003c\/li\u003e\n    \u003cli\u003eRibbon thickness: 1.8 µm; width: 4.7 mm; length: 59.7 mm\u003c\/li\u003e\n    \u003cli\u003eRibbon material: corrugated aluminum\u003c\/li\u003e\n    \u003cli\u003eResonant tuning: 16.5 Hz\u003c\/li\u003e\n    \u003cli\u003eConnector: XLR-3M on 3 m captive cable\u003c\/li\u003e\n    \u003cli\u003eDimensions: 295 mm (H) × 99 mm (W) × 64 mm (D)\u003c\/li\u003e\n    \u003cli\u003eWeight: 1.36 kg (with cable); 1.8 kg (with case)\u003c\/li\u003e\n    \u003cli\u003eMade in: USA (Pasadena, CA)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"AEA","offers":[{"title":"Default Title","offer_id":54014128619857,"sku":"25527","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AEAR841.jpg?v=1781105287","url":"https:\/\/wrdtunes.com\/fr-fr\/products\/aea-r84","provider":"Wired Tunes","version":"1.0","type":"link"}
