Instead of one gain stage it runs two 101 amplifier modules together with US-made input and output transformers.\u003c\/p\u003e\n\u003ch3\u003eOld console tone without owning the console\u003c\/h3\u003e\n\u003cp\u003eOriginal Spectra Sonics desks survive in a handful of rooms worldwide and cannot realistically be kept in service. The STX 100 D repeats the same circuit in a package over 75% smaller and drops into any 500 series rack, so the same character is available on a pair of snare channels without maintaining vintage hardware.\u003c\/p\u003e\n\u003ch3\u003eTransformers on both ends of the path\u003c\/h3\u003e\n\u003cp\u003eAn input transformer and an output transformer together produce a midrange density that a preamp with iron on one side only does not reach. A three-position pad plus continuously variable input and output controls let you place the operating point deliberately: back off for clarity, drive harder when a vocal should thicken on the louder phrases. With 64 dB of gain on tap, low-output ribbons and dynamics are not an issue.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMicrophone channel from the 1964-1971 Spectra Sonics consoles\u003c\/li\u003e\n\u003cli\u003eTwo 101 amplifier modules in a fully discrete topology\u003c\/li\u003e\n\u003cli\u003eUS-made input and output transformers\u003c\/li\u003e\n\u003cli\u003eSingle 500 series slot, original circuit reduced by over 75%\u003c\/li\u003e\n\u003cli\u003eThree-position pad with continuously variable input and output\u003c\/li\u003e\n\u003cli\u003e48 V phantom power and polarity reverse\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGain: 64 dB\u003c\/li\u003e\n\u003cli\u003eTHD: less than 0.03% at 20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003eSignal to noise: better than 120 dB, unweighted\u003c\/li\u003e\n\u003cli\u003eMaximum output: +18 dBm, 20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003ePower requirement: less than 50 mA at +18 dBm\u003c\/li\u003e\n\u003cli\u003eInput impedance: 600 Ohm nominal\u003c\/li\u003e\n\u003cli\u003eOutput impedance: less than 50 Ohm\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz - 50 kHz\u003c\/li\u003e\n\u003cli\u003ePhantom power: 48 V\u003c\/li\u003e\n\u003cli\u003ePolarity: 180 degree reverse, mic or line input\u003c\/li\u003e\n\u003cli\u003eInput\/output control: continuously variable, three-position pad\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Spectra 1964","offers":[{"title":"Default Title","offer_id":54556577005905,"sku":"60780","price":1299.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/Spectra1964STX100D1.jpg?v=1786971198","url":"https:\/\/wrdtunes.com\/fr\/products\/spectra-1964-stx-100-d","provider":"Wired Tunes","version":"1.0","type":"link"}
