Yadda ake saita amplifier tare da multimeter

Kiɗa yana da ƙarfi kuma tsarin sauti mai kyau yana sa ya fi kyau. Sami mafi kyawun tsarin sitiriyo na motar ku da tsarin sauti ta hanyar daidaita amplifier ɗinku da kyau tare da multimeter. Ba wai kawai yana kare kayan aikin ku ba, har ma yana ba da ingantaccen ingancin sauti.

Kuna iya daidaita ribar amplifier ɗin ku ta hanyar daidaita ƙarfin fitarwa na AC naúrar kai zuwa ƙarfin shigarwar ƙararrawa. Hakanan yana hana yanke sauti.

Don saita ikon samun riba, kuna buƙatar masu zuwa:

Multimeter na dijital, lasifika, manual amplifier, kalkuleta, da siginar gwaji CD ko filasha. Anan akwai umarnin mataki-mataki don kunna amplifier ta hanyoyi daban-daban.

Yadda za a kafa amplifier tare da multimeter?

Mataki 1: Auna rashin karfin lasifikar da multimeter.

Duba impedance lasifika. Za ku haɗa zuwa amplifier ta amfani da multimeter na dijital. Don yin wannan, kashe wuta ga lasifikar. Sa'an nan ƙayyade abin da tasha a kan lasifikar da yake tabbatacce kuma wanda ba shi da kyau. Haɗa jagorar gwajin ja zuwa madaidaicin tasha da gwajin baƙar fata zuwa mara kyau.

Rubuta juriya a cikin ohms da aka gani akan multimeter. Ka tuna cewa matsakaicin matsananciyar magana shine 2, 4, 8 ko 16 ohms. Don haka, ƙima mafi kusa da ƙimar da aka rubuta za a iya lura da shi tare da amincewa.

Mataki 2: Kula da shawarar da aka ba da ikon fitarwa na amplifier.

Ɗauki littafin mai amfani na amplifier kuma nemo ƙarfin fitarwa da aka ba da shawarar. Kwatanta wannan da juriyar lasifikar ku a cikin ohms.

Mataki na 3: Lissafin wutar lantarkin AC da ake buƙata

Yanzu muna buƙatar nemo maƙasudin ƙarfin lantarki don amplifier. Wannan shine ƙarfin fitarwa wanda muke buƙatar saita riba na amplifier. Don lissafta shi, muna buƙatar amfani da bambance-bambancen dokar Ohm, V = √ (PR), inda V shine wutar lantarki AC, P shine iko, R shine juriya (Ω).

Bari mu ce littafin ku ya ce amplifier ya kamata ya zama watts 500, kuma impedance na lasifikar ku, wanda kuka samo tare da multimeter, shine 2 ohms. Don warware ma'auni, ninka 500 watts ta 2 ohms don samun 1000. Yanzu yi amfani da kalkuleta don nemo tushen murabba'in 1000 kuma ƙarfin fitarwar ku ya kamata ya zama 31.62V a yanayin daidaitawar haɗin kai.

Idan kana da amplifier tare da sarrafa riba biyu, za a sarrafa su da kansu.

Misali, idan amplifier yana da watts 200 don tashoshi huɗu, yi amfani da ikon fitarwa na tashar ɗaya don ƙididdige ƙarfin lantarki. Wutar lantarki don kowane iko shine tushen murabba'in 200 watts x 2 ohms.

Mataki na 4 Cire duk na'urorin haɗi

Cire haɗin duk ƙarin na'urorin haɗi, gami da lasifika da subwoofers, daga amplifier ƙarƙashin gwaji. Cire haɗin tashoshi masu inganci kawai don ku tuna saitin lokacin da kuke buƙatar haɗa su baya.

Mataki 5: Saita Mai daidaitawa zuwa Sifili

Ko dai musaki mai daidaitawa ko saita duk saitunan sa kamar girma, bass, treble, sarrafawa, haɓaka bass da ayyukan daidaitawa zuwa sifili. Wannan yana hana tace raƙuman sauti don haka yana haɓaka kewayon bandwidth.

Mataki 6: Saita Gain zuwa Sifili

Ga mafi yawan amplifiers, ana samun mafi ƙarancin saiti ta hanyar juya bugun kira a kishiyar agogo gwargwadon yadda zai tafi.

Matakai 4, 5 da 6 suna barin amplifier da aka haɗa da wutar lantarki kawai.

Mataki na 7: saita ƙarar zuwa 75%

Kunna naúrar kai a 75% na matsakaicin ƙarar. Wannan zai hana a aika gurbatattun sautunan sitiriyo zuwa amplifier.

Mataki na 8 Kunna Sautin Gwaji

Kafin ci gaba, tabbatar da an cire haɗin lasifikar daga amplifier.

Yanzu kuna buƙatar sautin ringi na gwaji don gwada tsarin ku. Kunna siginar gwajin akan tsarin sitiriyo tare da igiyar sine a 0 dB. Sautin ya kamata ya kasance yana da mitar 50-60 Hz don amplifier na subwoofer da tsawon zangon 100 Hz don amplifier na tsakiya. Ana iya ƙirƙira shi da shirin kamar Audacity ko zazzage shi daga Intanet. (1)

Shigar da naúrar kai domin a ci gaba da kunna sautin.

Mataki 9: Haɗa Multimeter zuwa Amplifier

Saita DMM zuwa AC ƙarfin lantarki kuma zaɓi kewayon da ya ƙunshi ƙarfin wutan lantarki. Haɗa jagorar multimeter zuwa tashoshin fitarwa na lasifika. Ya kamata a sanya ingantaccen bincike na multimeter a cikin tashoshi mai kyau, kuma ya kamata a sanya mummunan binciken na multimeter a cikin mummunan tashar. Wannan yana ba ku damar auna wutar lantarki ta AC akan amplifier.

Idan wutar lantarki nan take da aka nuna akan multimeter ya fi 6V, maimaita matakai 5 da 6.

Mataki na 10: Daidaita Kullin Sami

Sannu a hankali kunna kullin ribar amplifier yayin lura da karatun ƙarfin lantarki akan multimeter. Dakatar da daidaita kullin da zaran multimeter ya nuna maƙasudin ƙarfin fitarwa na AC da kuka ƙididdige a baya.

Taya murna, kun daidaita ribar da aka samu akan amplifier dinku!

Mataki 11: Maimaita don sauran amps

Amfani da wannan hanyar, daidaita duk amplifiers a cikin tsarin kiɗanku. Wannan zai ba ku sakamakon da kuke nema - mafi kyau.

Mataki 12: Saita ƙarar zuwa sifili.

Rage ƙarar kan naúrar kai zuwa sifili kuma kashe tsarin sitiriyo.

Mataki 13: Toshe Komai Baya

Sake haɗa duk na'urorin haɗi kamar yadda za ku yi sauran amplifiers da lasifika; kun cire kafin shigar da riba. Tabbatar cewa an haɗa duk wayoyi daidai kuma kunna sashin kai.

Mataki na 14: Ji daɗin Kiɗa

Cire sautin gwajin daga sitiriyo kuma kunna ɗayan waƙoƙin da kuka fi so. Kewaye kanku da mugunyar kiɗa kuma ku more cikakkiyar murdiya.

Sauran hanyoyin kunna amplifier

Kuna iya daidaita ribar amp ɗin ku da haɓakar bass ta hanyar tweaking da hannu da sauraron abin da ya fi kyau. Amma wannan hanya ba a ba da shawarar ba saboda sau da yawa mun kasa kama mafi ƙanƙanta murdiya.

ƙarshe

Yin amfani da multimeter na dijital don daidaita riba yana ɗaya daga cikin mafi inganci kuma mafi sauƙi hanyoyin. Wannan yana ba ku damar saita fa'ida don kusan duk amplifiers. Hanya mafi kyau don hana duk wani murdiya a cikin tsarin ku shine amfani da oscilloscope. Yana gano daidai duk guntuwa da murdiya. (2)

Tare da mafi kyawun multimeter a hannu, muna fatan wannan jagorar zai taimaka muku saita amplifier ɗin ku daidai.

Hakanan zaka iya dubawa da karanta wasu litattafai ta amfani da multimeter wanda zai iya taimaka maka nan gaba. 'Yan kasidu sun haɗa da: Yadda ake gwada capacitor tare da multimeter da Yadda ake gwada baturi tare da multimeter.
