And some active speakers and pure power amplifiers have high gain themselves, so they needn't match active pre-amp to amplify the signal. Passive pre-amp is the best choice to reduce the sound rendering at the most extent because of no power transistor.\n\nProduct Details:\n\n\nHas no gain, such as input 1V, the maximum output is also 1V\n\nCan match power amplifiers, active speakers and some monitor devices very well with lossless sound quality.\n\nHigh-end texture, adopting full aluminum chassis and knob with CNC maching technology\n\nInput impedance: 50K\n\nColor: Black\n\nDimensions (W*H*D): 63.8MM*40MM*93MM\n\nNet weight: 0.28KG\n\nPackage List:\n\n\n1 × Preamplifier","brand":"mickcara","offers":[{"title":"black","offer_id":46440538013833,"sku":"NIMENJIAOWOZ","price":34.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0365\/2131\/2393\/files\/Sa2a71e4f1e314b6aac67406b4a0aeda0G.webp?v=1778050250","url":"https:\/\/mickcara.com\/products\/fv3-high-precision-passive-preamp-volume-controller-hifi-pre-amplifiers-for-power-amplifiers-or-active-speakers","provider":"mickcara","version":"1.0","type":"link"}
