{"product_id":"royer-ro-sf2mp","title":"Royer SF-2 Active Ribbon Microphone Matched Pair (Matte Black)","description":"\u003cp\u003eThe Royer SF-2 Matched Pair is two SF-2 phantom-powered ribbon microphones supplied by Royer Labs as a matched set for stereo work on choirs, orchestras, string sections, piano and drum overheads. Each mic's active electronics bring its output to -38 dB, on par with a phantom-powered condenser, with self-noise under 18 dB, so the pair runs on ordinary mic preamps. The 1.8-micron aluminum ribbons give 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\u003eEach SF-2 has a fully balanced, discrete head amplifier with a specially wound toroidal transformer and low-noise FETs. The transformer supplies an extra 14 dB of gain and the circuit runs below unity, so the higher output adds no noise. The electronics give each ribbon the correct load whatever preamp follows, and the low output impedance handles very long cable runs.\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, and it stays consistent at any distance from the source.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo SF-2 active ribbon microphones, sold as a matched pair\u003c\/li\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\u003eQuantity:\u003c\/strong\u003e 2 microphones, matched pair\u003c\/li\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) each\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","brand":"Royer","offers":[{"title":"Default Title","offer_id":67380197490937,"sku":"RO-SF2MP","price":5599.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/sf2-2_15125d3f-4393-485e-a160-38156d66440b.jpg?v=1792179649","url":"https:\/\/blackoutaudio.com\/products\/royer-ro-sf2mp","provider":"Blackout Audio","version":"1.0","type":"link"}
