Preamplifier (preamp) na'urar lantarki ne Amplifier wanda ke shirya ƙaramin siginar lantarki don ƙarin haɓakawa ko sarrafawa.
Sau da yawa ana sanya na'urar riga-kafi kusa da firikwensin don rage tasirin hayaniya da tsangwama. Ana amfani da shi don haɓaka ƙarfin siginar don fitar da kebul zuwa babban kayan aiki ba tare da rage girman sigina-zuwa-amo rabo (SNR).
Ayyukan amo na preamplifier yana da mahimmanci; bisa ga tsarin Friis, lokacin da riba na preamplifier yana da girma, SNR na siginar ƙarshe an ƙaddara ta SNR na siginar shigarwa da kuma sautin amo na preamplifier.
A cikin tsarin sauti na gida, ana iya amfani da kalmar 'preamplifier' wani lokaci don kwatanta kayan aiki waɗanda kawai ke musanya tsakanin matakan matakin layi daban-daban kuma suna amfani da ikon sarrafa ƙara, ta yadda babu ainihin ƙarawa da za a iya shiga.
A cikin tsarin sauti, amplifier na biyu yawanci ƙararrawar wuta ce (amplifier). The preamplifier yana ba da riba mai ƙarfin lantarki (misali daga 10 millivolts zuwa 1 volt) amma babu wani gagarumin riba na yanzu.
Ƙarfin wutar lantarki yana ba da mafi girman halin yanzu da ake buƙata don fitar da lasifika.
Ana iya haɗawa da na'urar faɗakarwa a cikin gidaje ko chassis na amplifier da suke ciyarwa a cikin keɓantaccen mahalli da aka saka a ciki ko kusa da tushen siginar, kamar na'urar juyawa, makirufo ko kayan kiɗa.
Nau'o'in Preamplifier: Akwai nau'ikan na'urori masu mahimmanci guda uku: na'urar tantancewa ta halin yanzu, na'ura mai karfin iya jurewa, da preamplifier mai caji.
