Momwe mungakhazikitsire amplifier ndi multimeter

Nyimboyi ndi yamphamvu ndipo kamvekedwe kabwino ka mawu kamapangitsa kuti zikhale zabwinoko. Pindulani bwino ndi stereo yamagalimoto anu ndi makina omvera posintha bwino amplifier yanu ndi multimeter. Sikuti zimangoteteza zida zanu, komanso zimapereka mawu abwino kwambiri.

Mutha kusintha kupindula kwa amplifier yanu pofananiza voteji ya AC ya mutu wagawo ndi mphamvu yolowera ya amplifier. Zimalepheretsanso kudula mawu.

Kuti mupange chiwongolero cha phindu, mudzafunika zotsatirazi:

Digital multimeter, okamba, buku lanu la amplifier, chowerengera, ndi CD yoyeserera kapena flash drive. Nawa malangizo atsatanetsatane akukonzekera amplifier m'njira zosiyanasiyana.

Momwe mungakhazikitsire amplifier ndi multimeter?

Khwerero 1: Yezerani kulephera kwa speaker ndi multimeter.

Onani kulephera kwa speaker. Mudzakhala mukulumikizana ndi amplifier pogwiritsa ntchito multimeter ya digito. Kuti muchite izi, zimitsani mphamvu kwa wokamba nkhani. Kenako dziwani kuti ndi terminal iti pa choyankhulirayo yomwe ili yabwino komanso yotsutsa. Lumikizani mayeso ofiira otsogolera ku terminal yabwino ndipo mayeso akuda amatsogolera ku terminal yoyipa.

Lembani kukana mu ohms kuwonedwa pa multimeter. Kumbukirani kuti kulepheretsa koyankhula kwakukulu ndi 2, 4, 8 kapena 16 ohms. Choncho, mtengo wapafupi kwambiri wamtengo wolembedwa ukhoza kuzindikiridwa ndi chidaliro.

Khwerero 2: Samalani ndi mphamvu yotulutsidwa ya amplifier.

Tengani kabuku kanu ka amplifier ndikupeza mphamvu zomwe zikulimbikitsidwa. Fananizani izi ndi kukana kwa speaker yanu mu ma ohms.

Khwerero 3: Werengetsani mphamvu ya AC yofunikira

Tsopano tiyenera kupeza voteji chandamale cha amplifier. Izi ndi mphamvu zotulutsa zomwe timafunikira kukhazikitsa phindu la amplifier. Kuti tiwerengere, tifunika kugwiritsa ntchito lamulo la Ohm, V = √ (PR), pomwe V ndiye voteji ya AC, P ndi mphamvu, ndipo R ndi kukana (Ω).

Tiyerekeze kuti buku lanu likunena kuti amplifier iyenera kukhala ma watts 500, ndipo kusokoneza kwa wokamba nkhani, komwe mudapeza ndi multimeter, ndi 2 ohms. Kuti muthane ndi equation, chulukitsani ma Watts 500 ndi 2 ohms kuti mupeze 1000. Tsopano gwiritsani ntchito chowerengera kuti mupeze muzu wapakati wa 1000 ndipo voteji yanu yotulutsa iyenera kukhala 31.62V ngati pali kusintha kwa mgwirizano.

Ngati muli ndi amplifier yokhala ndi zowongolera ziwiri, zidzasinthidwa paokha.

Mwachitsanzo, ngati amplifier ili ndi ma watts 200 pamayendedwe anayi, gwiritsani ntchito mphamvu yotulutsa njira imodzi kuwerengera voteji. Mphamvu yamagetsi pakuwongolera kulikonse ndi muzu wapakati wa 200 watts x 2 ohms.

Khwerero 4 Chotsani Zida Zonse

Lumikizani zida zonse zowonjezera, kuphatikiza okamba ndi ma subwoofers, kuchokera ku amplifier poyesedwa. Lumikizani ma terminals abwino okha kuti mukumbukire zoikamo mukafunika kuzilumikizanso.

Khwerero 5: Kukhazikitsa Equalizer kukhala Zero

Kapena zimitsani zofananira kapena ikani makonda ake onse monga voliyumu, bass, treble, processing, bass boost ndi ntchito zofananira mpaka zero. Izi zimalepheretsa mafunde amawu kuti asasefedwe ndipo motero amakulitsa kuchuluka kwa bandwidth.

Khwerero 6: Khazikitsani Gain to Zero

Kwa ma amplifiers ambiri, mawonekedwe ochepera amatheka potembenuza kuyimba motsatana ndi momwe kungathekere.

Masitepe 4, 5 ndi 6 amasiya amplifier olumikizidwa ndi magetsi okha.

Khwerero 7: Sinthani voliyumu kukhala 75%

Yatsani mutu wamutu pa 75% ya voliyumu yayikulu. Izi ziletsa kuti mawu opotoka a stereo asatumizidwe ku amplifier.

Khwerero 8: Sewerani Toni Yoyeserera

Musanapitirire, onetsetsani kuti wokamba nkhani wachotsedwa pa amplifier.

Tsopano muyenera kuyesa Ringtone kuyesa dongosolo lanu. Sewerani chizindikiro choyesa pa stereo system ndi sine wave pa 0 dB. Phokoso liyenera kukhala ndi ma frequency a 50-60 Hz a subwoofer amplifier ndi kutalika kwa 100 Hz kwa amplifier yapakati. Itha kupangidwa ndi pulogalamu monga Audacity kapena kutsitsa kuchokera pa intaneti. (1)

Ikani mutu wa mutu kuti phokoso likuseweredwa mosalekeza.

Khwerero 9: Lumikizani Multimeter ku Amplifier

Khazikitsani voliyumu ya DMM kukhala AC ndikusankha mitundu yomwe ili ndi voteji yomwe mukufuna. Lumikizani ma multimeter otsogolera ku madoko otulutsa mawu a amplifier. Kufufuza kwabwino kwa multimeter kumayenera kuyikidwa mu terminal yabwino, ndipo kafukufuku woyipa wa multimeter ayenera kuyikidwa mu terminal yoyipa. Izi zimakulolani kuyeza voteji ya AC pa amplifier.

Ngati mphamvu yotulutsa nthawi yomweyo yomwe ikuwonetsedwa pa multimeter ndi yayikulu kuposa 6V, bwerezani masitepe 5 ndi 6.

Khwerero 10: Sinthani Gain Knob

Pang'onopang'ono tembenuzirani mfundo ya amplifier pamene mukuyang'ana kuwerengera kwamagetsi pa multimeter. Lekani kusintha konoko pomwe ma multimeter akuwonetsa chandamale cha AC yotulutsa mphamvu yomwe mudawerengera kale.

Zabwino zonse, mwasintha bwino phindu pa amplifier yanu!

Khwerero 11: Bwerezani ma amps ena

Pogwiritsa ntchito njirayi, sinthani ma amplifiers onse mu nyimbo yanu. Izi zikupatsani zotsatira zomwe mumayembekezera - zabwino kwambiri.

Khwerero 12: Khazikitsani voliyumu kukhala ziro.

Chepetsani voliyumu pamutu mpaka ziro ndikuzimitsa sitiriyo.

Khwerero 13: Lumikizani Chilichonse Kubwerera

Lumikizaninso zida zonse monga momwe mungachitire ndi amplifiers ena ndi okamba; mudachotsa musanayike phindu. Onetsetsani kuti mawaya onse alumikizidwa bwino ndikuyatsa mutu.

Gawo 14: Sangalalani ndi Nyimbo

Chotsani nyimbo yoyeserera pa sitiriyo yanu ndikuyimba imodzi mwa nyimbo zomwe mumakonda. Dzizungulireni nokha ndi nyimbo zankhanza ndikusangalala ndi kupotoza koyenera.

Njira zina zosinthira amplifier

Mutha kusintha kupindula kwa amp ndi bass boost poyisintha pamanja ndikumvera zomwe zikumveka bwino. Koma njira imeneyi si ovomerezeka chifukwa nthawi zambiri timalephera kugwira zopotoka zing’onozing’ono.

Pomaliza

Kugwiritsa ntchito ma multimeter a digito kuti musinthe phindu ndi njira imodzi yothandiza komanso yosavuta. Izi zimakuthandizani kuti muyike mwayi kwa pafupifupi amplifiers onse. Njira yabwino yopewera kusokonekera kulikonse m'dongosolo lanu ndikugwiritsa ntchito oscilloscope. Imazindikira molondola kudula ndi kupotoza konse. (2)

Ndi multimeter yabwino kwambiri, tikukhulupirira kuti bukuli likuthandizani kukhazikitsa amplifier yanu moyenera.

Mukhozanso kuyang'ana ndikuwerenga zolemba zina pogwiritsa ntchito multimeter yomwe ingakuthandizeni mtsogolo. Nkhani zingapo zikuphatikizapo: Momwe mungayesere capacitor ndi multimeter ndi Momwe mungayesere batire ndi multimeter.
