{"product_id":"royer-ro-sf2","title":"Royer SF-2 Active Ribbon Microphone (Matte Black)","description":"\u003cp\u003eThe Royer SF-2 is a phantom-powered mono ribbon microphone designed for classical recording and acoustic instruments, from choir and strings to woodwinds, piano, harp and acoustic guitar. It is the active version of Royer's SF-1. Built-in electronics raise its output to -38 dB, on par with a phantom-powered condenser, so it works with almost any mic preamp, and self-noise stays under 18 dB. Its 1.8-micron aluminum ribbon gives fast transient response and a figure-8 pattern with equal pickup from front and back.\u003c\/p\u003e\n\n\u003ch3\u003eActive Electronics\u003c\/h3\u003e\n\u003cp\u003eA fully balanced, discrete head amplifier with a specially wound toroidal transformer and low-noise FETs drives the output. The transformer supplies an extra 14 dB of gain and the circuit runs below unity, so the higher output adds no noise. The electronics also give the ribbon the correct load whatever preamp follows, so the mic keeps its low end and body on any input, and the low output impedance handles very long cable runs. Phantom power, electrical glitches and miswired cables cannot damage the ribbon.\u003c\/p\u003e\n\n\u003ch3\u003eSound\u003c\/h3\u003e\n\u003cp\u003eThe magnet and pole-piece structure gives a wide, even frequency response with no large peaks or dips. Response holds up whatever the angle of the sound reaching the ribbon, so off-axis coloration is negligible. Before release, prototype SF-2s spent years in major studios and scoring stages on choir, piano, woodwinds and strings.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePhantom-powered electronics for high output and correct ribbon loading\u003c\/li\u003e\n  \u003cli\u003eOutput on par with phantom-powered condenser microphones\u003c\/li\u003e\n  \u003cli\u003eHandles 130 dB SPL at 70 Hz, with no distortion up to the maximum rating\u003c\/li\u003e\n  \u003cli\u003eExtremely low residual noise\u003c\/li\u003e\n  \u003cli\u003eRibbon unaffected by heat or humidity\u003c\/li\u003e\n  \u003cli\u003eNo high-frequency phase distortion\u003c\/li\u003e\n  \u003cli\u003eEqual sensitivity from the front and back\u003c\/li\u003e\n  \u003cli\u003eConsistent frequency response regardless of distance\u003c\/li\u003e\n  \u003cli\u003eHigh-efficiency toroidal transformer and gold-plated output connector\u003c\/li\u003e\n  \u003cli\u003eVery low magnetic leakage\u003c\/li\u003e\n  \u003cli\u003eMatte black finish cuts reflected light on stage and on camera\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating principle:\u003c\/strong\u003e Electrodynamic pressure gradient with active electronics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePolar pattern:\u003c\/strong\u003e Figure-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElement:\u003c\/strong\u003e 1.8-micron aluminum ribbon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnets:\u003c\/strong\u003e Neodymium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 30 Hz to 15 kHz, +\/- 2 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e -38 dBV (re. 1 V\/Pa)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-noise:\u003c\/strong\u003e Under 18 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum SPL:\u003c\/strong\u003e Over 130 dB (130 dB at 70 Hz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput impedance:\u003c\/strong\u003e 200 ohms at 1 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated load impedance:\u003c\/strong\u003e Over 1,500 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput connector:\u003c\/strong\u003e 3-pin male XLR (pin 2 hot)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 48 V phantom, 4 mA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 203 mm long, 39 mm at the base, 25 mm at the top (8 x 1.5 x 1 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 448 g (15.8 oz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Matte black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 10 years on materials, workmanship and finish to the original owner; first re-ribbon free within one year\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSF-2 microphone\u003c\/li\u003e\n  \u003cli\u003eSF-2 shock mount\u003c\/li\u003e\n  \u003cli\u003eMicrophone sock\u003c\/li\u003e\n  \u003cli\u003eCable ties\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Royer","offers":[{"title":"Default Title","offer_id":67380197261561,"sku":"RO-SF2","price":2749.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/sf2-1.jpg?v=1792176216","url":"https:\/\/blackoutaudio.com\/products\/royer-ro-sf2","provider":"Blackout Audio","version":"1.0","type":"link"}
