It's the two-channel counterpart to the single-channel 40AM-1 module from the same octal Locomotive preamp family.\u003c\/p\u003e\n\u003ch3\u003eTwice the same heavy American character\u003c\/h3\u003e\n\u003cp\u003eEach channel repeats the 40AM-1 design: two 6SJ7 tubes (pentode input, triode output) and a maximum gain of 52dB, built on the same topology combining the RCA BA-11A and Gates SA-70 from 1940s American broadcast radio. MuMetal input transformers and nickel-and-steel output transformers, wound in-house, are shared across both channels.\u003c\/p\u003e\n\u003ch3\u003eA dedicated line input with no phantom power risk\u003c\/h3\u003e\n\u003cp\u003eEach channel gets its own 5-position Response switch, 5-position mic\/line input switch, -20dB pad, 85Hz high-pass filter and high-impedance front-panel DI input. A separate line-level XLR input lets you send a line signal in \"around\" the mic circuit, with no risk of accidentally applying phantom power to a sensitive source. Two channels of the same octal electronics in one unit make stereo tracking or parallel-doubling a track with the same dense tonal character straightforward.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2-channel octal tube preamp, standalone rack chassis\u003c\/li\u003e\n\u003cli\u003eTwo independent 40AM-1 circuits in one unit\u003c\/li\u003e\n\u003cli\u003eTubes: 2x 6SJ7 per channel\u003c\/li\u003e\n\u003cli\u003eMaximum gain: 52dB per channel\u003c\/li\u003e\n\u003cli\u003e5-position Response switch per channel\u003c\/li\u003e\n\u003cli\u003eDedicated line XLR input with no phantom power risk\u003c\/li\u003e\n\u003cli\u003e-20dB pad and 85Hz high-pass filter per channel\u003c\/li\u003e\n\u003cli\u003eHand-built in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: 2-channel octal tube preamp\u003c\/li\u003e\n\u003cli\u003eTubes: 2x 6SJ7 per channel\u003c\/li\u003e\n\u003cli\u003eMaximum gain: 52dB per channel\u003c\/li\u003e\n\u003cli\u003eTransformers: MuMetal input, nickel-and-steel output, in-house wound\u003c\/li\u003e\n\u003cli\u003ePad: -20dB per channel\u003c\/li\u003e\n\u003cli\u003eHigh-pass filter: 85Hz per channel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Locomotive Audio","offers":[{"title":"Default Title","offer_id":54961112842577,"sku":"61011","price":2699.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/Locomotive_Audio_40AM-2_1.jpg?v=1789721088","url":"https:\/\/wrdtunes.com\/es\/products\/locomotive-audio-40am-2","provider":"Wired Tunes","version":"1.0","type":"link"}
