Only forty-eight originals were ever built. Acme Audio spent several weeks taking one apart under McLean's own guidance.\u003c\/p\u003e\n\u003ch3\u003eStepped control instead of faders\u003c\/h3\u003e\n\u003cp\u003eRather than sliders the unit uses rotary switches, and each band tops out at 8 dB. That sounds modest until you put it on bass or a horn section: the passive inductor circuit shapes the band gently and without phase artefacts, so 3 dB here does more than 6 dB on a typical digital equalizer.\u003c\/p\u003e\n\u003ch3\u003ePeriod-correct parts, not close approximations\u003c\/h3\u003e\n\u003cp\u003eInductors are wound by Mesanovic on MPP cores, the input transformer is an AMI A24, the output transformer is custom made, and the output stage is built around an Opamp Labs 425 amplifier. Values and tolerances follow the original rather than modern equivalents with similar figures on paper. The power supply sits outside the chassis, which lowers the noise floor. Response reaches from 10 Hz to 30 kHz within 1 dB.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSeven-band passive graphic equalizer on rotary switches\u003c\/li\u003e\n\u003cli\u003eRecreation of Mike McLean's design for Motown Records\u003c\/li\u003e\n\u003cli\u003eMesanovic inductors on MPP cores\u003c\/li\u003e\n\u003cli\u003eAMI A24 input transformer and custom output transformer\u003c\/li\u003e\n\u003cli\u003eOpamp Labs 425 output amplifier\u003c\/li\u003e\n\u003cli\u003eExternal power supply for a lower noise floor\u003c\/li\u003e\n\u003cli\u003e19 inch, 2U aluminium rack chassis\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: passive graphic equalizer, seven bands\u003c\/li\u003e\n\u003cli\u003eFrequencies: 50 Hz, 130 Hz, 320 Hz, 800 Hz, 2 kHz, 5 kHz, 12.5 kHz\u003c\/li\u003e\n\u003cli\u003eRange: +\/- 8 dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz - 30 kHz, +\/- 1 dB\u003c\/li\u003e\n\u003cli\u003eMaximum level: 29 dB\u003c\/li\u003e\n\u003cli\u003eInput transformer: AMI A24\u003c\/li\u003e\n\u003cli\u003eOutput transformer: custom made by Mesanovic\u003c\/li\u003e\n\u003cli\u003eOutput amplifier: Opamp Labs 425\u003c\/li\u003e\n\u003cli\u003eConnectors: XLR input and output\u003c\/li\u003e\n\u003cli\u003eChannels: 1\u003c\/li\u003e\n\u003cli\u003eFormat: 19 inch rackmount, 2U, aluminium chassis\u003c\/li\u003e\n\u003cli\u003ePower: external power supply included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"ACME","offers":[{"title":"Default Title","offer_id":54554195951953,"sku":"60751","price":6999.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AcmeAudioMotownEQ1.jpg?v=1786971616","url":"https:\/\/wrdtunes.com\/fr\/products\/acme-audio-motown-eq","provider":"Wired Tunes","version":"1.0","type":"link"}
