High band centres are 2.5 kHz, 5 kHz, 10 kHz and 15 kHz; low band centres are 50 Hz, 100 Hz, 200 Hz and 300 Hz. Each band has its own bypass, so an A\/B against the unprocessed signal takes a second. The module needs a direct connection to an STX 100 and does not run on its own, as it carries no VPR edge connector.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-band passive equalizer designed to pair with the STX 100 preamp\u003c\/li\u003e\n\u003cli\u003eZero insertion loss thanks to operation inside the feedback loop\u003c\/li\u003e\n\u003cli\u003eFour selectable centre frequencies per band\u003c\/li\u003e\n\u003cli\u003eUp to 12 dB of boost and cut in 2 dB increments\u003c\/li\u003e\n\u003cli\u003eIndependent bypass for each band\u003c\/li\u003e\n\u003cli\u003eBuilt at the Spectra 1964 facility in Ogden, USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: two-band passive equalizer\u003c\/li\u003e\n\u003cli\u003eHigh frequency centres: 2.5 kHz, 5 kHz, 10 kHz, 15 kHz\u003c\/li\u003e\n\u003cli\u003eLow frequency centres: 50 Hz, 100 Hz, 200 Hz, 300 Hz\u003c\/li\u003e\n\u003cli\u003eRange: up to 12 dB boost and cut\u003c\/li\u003e\n\u003cli\u003eStep size: 2 dB\u003c\/li\u003e\n\u003cli\u003eBypass: independent per band\u003c\/li\u003e\n\u003cli\u003eInsertion loss: zero when combined with the STX 100\u003c\/li\u003e\n\u003cli\u003eRequirements: direct connection to an STX 100 preamp, no own VPR edge connector\u003c\/li\u003e\n\u003cli\u003eComponents: over 95% sourced in the USA and Europe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Spectra 1964","offers":[{"title":"Default Title","offer_id":54556577431889,"sku":"60781","price":1099.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/Spectra1964STX5001.jpg?v=1786971184"},{"product_id":"spectra-1964-bb-di","title":"Spectra 1964 BB-DI","description":"\u003cdiv lang=\"en\"\u003e\n\u003cp\u003e\u003cstrong\u003eSpectra 1964 BB-DI\u003c\/strong\u003e is a passive direct box built around a proprietary Hi-Z transformer custom-wound by Cinemag.
