Zaɓin amplifier don tsarin sautinku

Da farko kallo, yana iya zama kamar tsarin zaɓin amplifier a cikin mota don masu magana ko subwoofer ba haka ba ne mai sauƙi. Amma samun taƙaitaccen umarni "Yadda za a zabi amplifier" ba zai haifar da matsala ba. Manufar amplifier don tsarin sauti shine ɗaukar sigina mara ƙarfi kuma a canza shi zuwa sigina mai girma don fitar da lasifikar.

Suna iya bambanta a yawan tashoshi na haɓakawa, ƙarfi da farashi. Na'urorin haɓaka tashoshi biyu da huɗu suna cikin mafi girman buƙata tsakanin masu ababen hawa. Kuma yanzu bari mu amsa tambayar yadda za a zabi amplifier a cikin mota daki-daki.

Azuzuwan Amplifier Mota

Da farko, Ina so in yi magana game da azuzuwan amplifier, a halin yanzu akwai adadi mai yawa, amma za mu yi la'akari da manyan guda biyu waɗanda suka zama ruwan dare a cikin tsarin sauti na mota. Idan kuna sha'awar wannan batu daki-daki, a ƙarshen labarin akwai bidiyon da ke magana game da duk nau'ikan amplifiers na atomatik waɗanda aka samo yanzu.

• Class AB amplifier. Wadannan amplifiers suna da ingancin sauti mai kyau, tare da haɗin haɗin da ya dace suna da abin dogara kuma masu dorewa. Idan amplifier na aji AB yana da iko mai girma, to yana da girma gaba ɗaya, waɗannan amplifiers suna da ƙarancin inganci na kusan 50-60%, watau idan ana ciyar da watts 100 a cikin su. makamashi, to a halin yanzu na 50-60 watts zai kai ga masu magana. Sauran makamashin ana canza su zuwa zafi kawai. Ba shi yiwuwa a shigar da amplifiers na aji AB a cikin rufaffiyar sarari, in ba haka ba, a cikin yanayin zafi, zai iya shiga cikin kariya.
• Class D amplifier (amfanin dijital). Ainihin, ana samun ajin D a cikin monoblocks (masu haɓaka tashoshi ɗaya), amma akwai kuma tashoshi huɗu da biyu don haɗa sautin murya. Wannan amplifier yana da fa'idodi da yawa. Idan aka kwatanta da ajin AB, tare da iko iri ɗaya, yana da ƙananan girma. Ingancin waɗannan amplifiers na iya kaiwa 90%, kusan ba ya zafi. D aji na iya aiki a tsaye a ƙarƙashin ƙananan nauyin ohmic. Komai zai yi kyau, amma ingancin sautin waɗannan amplifiers ya yi ƙasa da ajin AB.

Mun kammala wannan sashe da ƙarshe. Idan kuna neman ingancin sauti (SQ), to zai zama mafi daidai don amfani da amplifiers na aji AB. Idan kuna son gina tsarin mai ƙarfi sosai, to yana da kyau ku zaɓi masu haɓaka Class D.

Adadin tashoshin amplifier.

Batu mai mahimmanci na gaba shine adadin tashoshin amplifier, ya dogara da abin da zaku iya haɗawa da shi. Komai yana da sauki a nan, amma bari mu duba a hankali:

         

• Amplifiers guda ɗaya, ana kuma kiran su monoblocks, an tsara su don haɗa subwoofers, galibi suna da aji D da ikon yin aiki da ƙarancin juriya. Ana yin saitunan (tace) don subwoofer, watau idan kun haɗa mai magana mai sauƙi zuwa monoblock, zai sake haifar da bass na yanzu.

 

• Amplifier na tashoshi biyu, kamar yadda zaku iya tsammani, zaku iya haɗa masu magana biyu zuwa gare shi. Amma kuma yawancin amplifiers na tashoshi biyu na iya aiki cikin yanayin gada. Wannan shine lokacin da aka haɗa subwoofer zuwa tashoshi biyu. Wadannan amplifiers suna da saitunan duniya (tace), watau suna da sauyawa na HPF, wannan yanayin yana sake haifar da ƙananan mita na yanzu, kuma lokacin da aka canza zuwa tace LPF, amplifier zai fitar da ƙananan mitoci (wannan saitin yana da mahimmanci ga subwoofer).
• Idan kun fahimci abin da amplifier na tashoshi biyu yake, to komai yana da sauƙi tare da tashoshi huɗu, waɗannan nau'ikan amplifiers guda biyu ne, watau zaku iya haɗa masu magana guda huɗu zuwa gare shi, ko 2 speakers da subwoofer, a cikin lokuta masu wuya biyu subwoofers ne. an haɗa, amma ba mu bayar da shawarar yin wannan ba. Amplifier zai yi zafi sosai kuma nan gaba yana iya zama mara amfani.
  
  Uku da biyar amplifiers tashoshi ba kasafai suke ba. Komai yana da sauƙi a nan, za ku iya haɗa masu magana guda biyu da subwoofer zuwa tashar tashar tashar tashoshi uku, masu magana da 4 da subwoofer zuwa amplifier tashoshi biyar. Suna da duk masu tacewa don daidaita abubuwan da aka haɗa da su, amma a matsayin mai mulkin, ikon waɗannan amplifiers kadan ne.

A cikin rufewa, ina so in faɗi mai zuwa. Idan kun kasance sababbi ga sautin mota kuma kuna son samun ingantaccen sauti mai inganci, daidaitacce, muna ba ku shawara ku zaɓi amplifier tashoshi huɗu. Tare da shi, zaku iya haɗa lasifikan gaba da subwoofer m. Wannan zai ba ku ingantacciyar gaba mai ƙarfi, goyon baya ta hanyar haɗin subwoofer.

Amplifier iko.

Ƙarfi yana ɗaya daga cikin mahimman sigogi. Da farko, bari mu gano menene bambanci tsakanin ƙididdiga da mafi girman iko. Ƙarshen, a matsayin mai mulkin, an nuna shi a jikin amplifier, bai dace da gaskiya ba kuma ana amfani dashi azaman tallan talla. Lokacin siyan, kuna buƙatar kula da ikon da aka ƙima (RMS). Kuna iya duba wannan bayanin a cikin umarnin, idan an san samfurin lasifikar, za ku iya samun halaye akan Intanet.

Yanzu 'yan kalmomi kan yadda ake zabar ƙarfin amplifier da lasifika. Kuna son ƙarin koyo game da zaɓin lasifika? Karanta labarin "yadda za a zabi sautin mota". Hakanan masu magana da mota suna da ƙima mai ƙarfi, a cikin umarnin ana kiranta da RMS. Wato, idan acoustics yana da ƙimar ƙarfin 70 watts. Sa'an nan da maras muhimmanci ikon amplifier ya zama kamar guda, daga 55 zuwa 85 watts. Misali na biyu, wane irin amplifier ake buƙata don subwoofer? Idan muna da subwoofer tare da rated ikon (RMS) na 300 watts. Ikon amplifier ya kamata ya zama 250-350 watts.

Ƙarshen sashe. Yawancin iko tabbas yana da kyau, amma bai kamata ku bi shi ba, saboda akwai amplifiers tare da ƙarancin ƙarfi, kuma suna wasa da kyau da ƙarfi fiye da waɗanda ba masu tsada ba amma tare da yin aiki mai ƙarfi.

Sunan furodusa.

 

Lokacin siyan amplifier, yana da matukar mahimmanci a kula da wane masana'anta ya yi shi. Idan ka sayi kayan aikin hannu, da kyar ba za ka iya dogaro da ingancin sauti mai kyau ba. Zai fi kyau a juya zuwa nau'ikan hauka waɗanda ke kan kasuwa na dogon lokaci kuma sun riga sun sami girmamawa da daraja suna. Misali, kamfanoni irin su Hertz, Alpine, DLS, Focal. Daga mafi yawan kasafin kuɗi, zaku iya karkatar da hankalin ku ga irin waɗannan samfuran kamar; Alphard, Blaupunkt, JBL, Ural, Swat, da dai sauransu.

Shin kun yanke shawarar zaɓin amplifier? Labari na gaba wanda zai zama da amfani a gare ku shine "yadda ake haɗa amplifier mota."

Yadda ake zabar amplifier a cikin mota (bidiyo)

Amplifiers don SQ. Yadda ake zabar amplifier a cikin mota

Tabbas, waɗannan ba duka alamomi bane waɗanda yakamata ku kula da lokacin zabar amplifier, amma sune manyan. Bin shawarwarin da aka zayyana a cikin labarin, zaku iya zaɓar ingantaccen ƙararrawa don tsarin sautinku. Muna fata da gaske cewa mun amsa tambayar ku game da yadda ake zabar amplifier don masu magana ko subwoofer, amma idan har yanzu kuna da maki ko buri mara kyau, za mu yi farin cikin amsa ta a cikin sharhin da ke ƙasa!
