The sound pickup is lush, smooth and natural, with outstanding stereo imaging and superb transient response. The tube electronics provide increased midrange reach, unmatched clarity and detail, and an airiness previously unheard of in ribbon mics. Utilizing the same proprietary tube electronics as in the TEC Award winning R-122V ribbon microphones, the SF-24V delivers the ultimate in stereo ribbon miking for the true connoisseur of recorded sound.\u003c\/p\u003e\n\u003cp\u003eThe SF-24V’s independent tube circuits provide an output level of -38 dB, suitable for use with any professional preamplifier. With self-noise of lower than 18 dB, the SF-24V’s ultra-quiet operation is suitable for the most demanding classical and acoustic recording applications. Like an SF-12, the SF-24V is actually two matched ribbon microphones, placed one above the other in a coincident pair, each aimed 45 degrees from center in the classic Blumlein configuration. The magnet\/pole piece structure of each ribbon transducer delivers a wide, uniform frequency response with no substantial peaks or dips, and the 1.8-micron ribbons produce superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible.\u003c\/p\u003e\n\u003ch3 id=\"toc_0\"\u003eTHE ELECTRONICS\u003c\/h3\u003e\n\u003cp\u003eThe SF-24V’s twin head amplifiers consist of low-noise, triode-connected military grade 5840 vacuum tubes. Designed for a wide range of applications, the SF-24V delivers -38 dB output and the drive capabilities only vacuum tube head amplifiers can provide. The circuits are devoid of typical vacuum tube coloration. The SF-24V’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 SF-24V’s dedicated power supply, which provides ample current to the vacuum tube electronics. Induced noise is virtually eliminated by the microphone’s fully balanced outputs, which are electrically isolated with special purpose Jensen output transformers.\u003c\/p\u003e\n\u003cp\u003eThe SF-24V 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. In addition, the microphone’s electronics shield the ribbon elements from any possibility of damage by phantom power, electrical glitches or miswired cables.\u003c\/p\u003e\n\u003ch3 id=\"toc_1\"\u003eRECORDING\u003c\/h3\u003e\n\u003cp\u003eThe SF-24V excels on full orchestra, choir and ensembles, classical piano, drum overheads, virtually all acoustic instruments, small vocal groups, a wide variety of percussion instruments, as a room mic, etc. Like the SF-12, the SF-24V is uncanny for creating “you-are-there” stereo recordings that capture not only the instrument(s) being recorded, but, depending on how the microphone is positioned, varying degrees of the acoustical space. In addition, the increased sensitivity and impedance matching circuitry allows for more consistent results in a variety of recording situations and with a wider selection of mic pre’s.\u003c\/p\u003e","brand":"Royer Labs","offers":[{"title":"Default Title","offer_id":44449232027751,"sku":"14041","price":6999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/royer-labs-sf24v-mic_14041_1.jpg?v=1792522051","url":"https:\/\/vintageking.com\/products\/royer-labs-sf-24v","provider":"Vintage King","version":"1.0","type":"link"}
