A preamplifier (preamp) imagetsi Amplifier iyo inogadzirira chiratidzo chidiki chemagetsi kuti chiwedzere kuwedzera kana kugadzirisa.
A preamplifier inowanzoiswa padyo ne sensor kuderedza mhedzisiro yeruzha uye kukanganisa. Iyo inoshandiswa kukwidziridza simba rechiratidzo kutyaira tambo kune chikuru chiridzwa pasina kushatisa zvakanyanya chiratidzo-ku-ruzha reshiyo (SNR).
Kuita ruzha rwe preamplifier kwakakosha; maererano nefomura yaFris, apo iyo pfuma yepreamplifier yakakwira, iyo SNR yechiratidzo chekupedzisira inotemerwa neSNR yechiratidzo chekuisa uye iyo ruzha nhamba ye preamplifier.
Muimba yekuteerera sisitimu, izwi rekuti 'preamplifier' dzimwe nguva rinogona kushandiswa kurondedzera midziyo inongochinja pakati peakasiyana mutsara masosi masosi uye inoshandisa vhoriyamu kutonga, kuti pasave nekukwidziridzwa chaiko kungave kubatikana.
Mune odhiyo system, yechipiri amplifier inowanzoita simba amplifier (simba amp). Iyo preamplifier inopa voltage kuwana (semuenzaniso kubva pagumi millivolts kusvika 10 volt) asi hapana yakakosha kuwana ikozvino.
Iyo simba amplifier inopa yakakwira ikozvino inodiwa kutyaira magudzanzwi.
Preamplifiers inogona kunge iri: inosanganisirwa mudzimba kana chassis yeamplifier yavanodyisa mune imwe imba yakasimudzwa mukati kana padhuze nechiratidzo chechiratidzo, senge turntable, maikorofoni kana chiridzwa chemumhanzi.
Preamplifier Types: Mhando nhatu dzekutanga dzepreamplifier dziripo: ikozvino-sensitive preamplifier, iyo parasitic-capacitance preamplifier, uye charge-sensitive preamplifier.
Ini ndini Joost Nusselder, muvambi weNeaera uye mushambadzi wemukati, baba, uye ndinoda kuyedza michina mitsva ine gitare pamoyo pechido changu, uye pamwe nechikwata changu, ndanga ndichigadzira zvakadzama zvinyorwa zveblog kubva 2020. kubatsira vaverengi vakavimbika nekurekodha nemagitare.
