Its ancestor was the five-channel Motown input box that guitars and bass ran through in Detroit from 1966 to 1972.\u003c\/p\u003e\n\u003ch3\u003eInstrument straight into the tubes, no amplifier\u003c\/h3\u003e\n\u003cp\u003eInstead of miking an amp in a booth, bass goes directly into a tube path feeding a Cinemag output transformer. There is no baffling to arrange and no bleed to fight, and the signal arrives with density and compression that a clean direct box does not provide. A quarter-inch through output sends the instrument to an amplifier in parallel.\u003c\/p\u003e\n\u003ch3\u003eDrive set at two points in the chain\u003c\/h3\u003e\n\u003cp\u003eThe original had no input or output control. The MTP-66 has both, so you can push the tubes hard and pull level back at the output, or work cleanly: that is what sets the amount of drive and natural compression. The microphone section is built on a fixed-gain pentode with an Acme Audio\/Triad transformer and a 15 dB pad. The unit does not provide phantom power.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRecreation of the Motown input box from the 1966 schematics\u003c\/li\u003e\n\u003cli\u003eAll-tube signal path with hand-selected tubes\u003c\/li\u003e\n\u003cli\u003eCinemag output transformer\u003c\/li\u003e\n\u003cli\u003eMicrophone section with fixed-gain pentode and Acme Audio\/Triad transformer\u003c\/li\u003e\n\u003cli\u003eIndependent input and output controls, absent from the original\u003c\/li\u003e\n\u003cli\u003eQuarter-inch instrument through output\u003c\/li\u003e\n\u003cli\u003eCustom VU meter in a rugged steel enclosure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: tube microphone preamp and DI, single channel\u003c\/li\u003e\n\u003cli\u003eGain: 36 dB\u003c\/li\u003e\n\u003cli\u003eTubes: EF86, two 12AT7, 6V6\u003c\/li\u003e\n\u003cli\u003eOutput transformer: Cinemag\u003c\/li\u003e\n\u003cli\u003eMicrophone input transformer: Acme Audio\/Triad\u003c\/li\u003e\n\u003cli\u003eInputs: 1\/4\" Hi-Z, XLR microphone\u003c\/li\u003e\n\u003cli\u003eOutputs: XLR main, 1\/4\" instrument through\u003c\/li\u003e\n\u003cli\u003eMicrophone input pad: 15 dB\u003c\/li\u003e\n\u003cli\u003ePhantom power: not provided\u003c\/li\u003e\n\u003cli\u003ePower: 115\/230 V, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eWeight: 11.5 lbs (approx. 5.2 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"ACME","offers":[{"title":"Default Title","offer_id":54554195558737,"sku":"58198","price":2399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AcmeAudioMTP-66MotownTubePreamplifierandDI1.jpg?v=1786971662","url":"https:\/\/wrdtunes.com\/products\/acme-audio-mtp-66-motown-tube-preamplifier-and-di","provider":"Wired Tunes","version":"1.0","type":"link"}
