Using 6J5 tube, NE5532\u003cbr\u003e\u003cbr\u003e3. The resistor uses high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.\u003cbr\u003e4. PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality.\u003cbr\u003e5. The input and output are made of gold-plated RCA lotus seat, which is durable and beautiful! The board layout is reasonable, beautiful, and the current is small.\u003cbr\u003e\u003cbr\u003eBasic parameters:\u003cbr\u003ePower supply: DC12V2A ( needs to be regulated by 12V, not higher than 12V)\u003cbr\u003eMachine size: about 129 x 100 x 35MM (without tube height)\u003cbr\u003ePanel function: switch treble adjustment bass adjustment total volume\u003cbr\u003eNote:\u003cbr\u003e1. This finished machine is a preamplifier, not an amplifier. It should be used with a post-amplifier or an active speaker. It is not allowed to directly connect passive speakers, speakers and earphones to the power amplifier; if it is not used, the car will be burnt if the voltage is unstable.\u003cbr\u003e\u003cbr\u003e3. Make sure that there is no problem with your source. The preamplifier itself has a preamplifier function. If the source itself is noisy, then the preamplifier will only amplify its noise. Please use a good source test.\u003cbr\u003e\u003cbr\u003eNote:\u003cbr\u003ePower supply is not included in the package. You need to buy 12V2A power supply by yourself.\u003cbr\u003eMaterial:Aluminum alloy\u003cbr\u003ecolour:Silver\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"mickcara","offers":[{"title":"Silver","offer_id":42999500669065,"sku":"2e8223-1-Silver","price":133.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0365\/2131\/2393\/files\/17d18fb42f16f56f65e8571bb478131c.jpg?v=1727159594","url":"https:\/\/mickcara.com\/fr\/products\/2x-buffer-hifi-6j5-bluetooth-4-2-tube-preamp-amplifier-stereo-preamplifier-with-treble-bass-tone-ustmentsier","provider":"mickcara","version":"1.0","type":"link"}
