Pre-gudzazwi nokuda subwoofer

Vanoda mumhanzi, kana kuona mafirimu pamusoro guru chidzitiro musha yemitambo, zvirokwazvo, vanofarira sei kuti yepamusoro inzwi. Naizvozvo, zvakakosha kuti preamplifier vanosarudza kuva mugumisiro hainyadzisi chii maitiro kutsvaka kana Pakusarudza zvakarekodhwa mudziyo.

Kana mimhanzi pamusoro CD-mutambi inoda imwe gudzazwi nekuti chiratidzo vakashandira simba chaizvo chechetere. Kuti abatsire mbiru chokuita gudzazwi. Iye anokwanisa nokuchinja uye kuwana Audio chiratidzo, nokumutsa nayo kuna achida vhoriyamu.

Amplifiers akakamurwa mhando nhatu: rokutanga, Integrated uye simba amplifiers. Chinokosha, iro rinobatanidza zvinhu zvose chimwe pasuru, pari rakajairika. Anodhura uye unhu anoonekwa ari oga redunhu mudziyo zvinosanganisira simba gudzazwi uye preamplifier. The amplifiers vari chubhu, transistor.

Zviri rokutanga shanduro anokwanisa kupa mumhanzi zvechokwadi vanoda kurira kuti aida kunzwa - yakachena uye yepamusoro, mupenyu zvechokwadi.

Kusarudza kubva muchikwata dzinodhura multi-mugero digitaalinen hurongwa, unogona kugara panguva AV-processor. Asi chisarudzo pakati amplifiers, zviri nani kupa kupfuura imwe preamplifier, inova yakanakisisa ukoshi mari. The processor anokwanisa zvakanaka kuchinja parameters uye vakombe kugadzira. Somugumisiro, unogona unganidza zvinotevera okuteerera ezvinhu kuti rinosanganisira itsime (semuenzaniso, CD mutambi), preamplifier, gudzazwi uye vakurukuri. Sezvo bhuku rinogona kushanda mutambi raive nebutiro zvinyorwa, kukaseti uriri uye dzimwe pfungwa. In basa preamplifier zvinogona kushandiswa AV-processor. Preamplifiers vabudirire pachiimbwa digitaalinen makaseti gadziriro, umo zvinoumba peya simba amplifiers. Izvi zvinobvumira muridzi nyanzvi acoustics kudzivisa zvikanganiso kana kuridza mumhanzi kurekodha uye neutralize kakawanda resonances kuri mumba.

Kwerubwinyo rwakagara rwuripo-gudzazwi nokuda subwoofer akapa kutsvakwa inzwi quality, zvakakodzera kupfeka ake EQ centre maitikiro pedyo mumwe kilohertz, uye midrange akaisa pasi poldetsibela.

Kugadziridza kurira kuti preamplifier vanofanira kuuya nacho kuna kufadza, uye pasuo ane gudzazwi ane mashoma chechetere. Kurira dzichavapo yepamusoro yepamusoro kana goho impedance pamusoro preamplifier dererei pane mazano voltage kuti simba gudzazwi. Well dzichienderana chubhu redhiyo amplifiers uye transistor simba amplifiers. Unogona batanidza kuti rokutanga shanduro Powered vatauri, asi inzwi rakanaka, unogona chete kuwana kana uchishandisa Studio-unhu yokutevedzera.

Sezvo kutonga, preamp kunoita basa controller, izvo zvinoita kuti kuchinja vhoriyamu uye mataurire Audio ezvinhu, chinja makaseti zvinyorwa uye anogadzira mureza simba gudzazwi. Kusiyana vapedzisira, mumwe preamplifier pamberi.

Kana ukasarudza munhu yepamusoro preamplifier, ichi Nzira kirasi «High End», semuenzaniso, «Evolution», akasikwa kubudikidza vagadziri German. Zvasvikira vaifanira nokwawakarerekera, processing mazano Audio chiratidzo. The midziyo ine chaikosha akakwana nechigadziko, pfupi uye akatsiga anonongedzera kuburikidza nesimba rive. Predusilistel imwe monkey goho kubva subwoofer Satellite akaisa-pamusoro mabhokisi ari, rinogona revatema tuner uye ichiita mabasa akawanda fonokorrektor preamplifier. Pasina mubvunzo, pane mudziyo akadaro anogona kununura akawanda papera vateereri ichi.
