Indlela yokusetha i-amplifier nge-multimeter

Umculo unamandla futhi uhlelo oluhle lomsindo luwenza ube ngcono nakakhulu. Thola okuningi ku-stereo yemoto yakho nesistimu yomsindo ngokulungisa kahle i-amplifier yakho nge-multimeter. Ayivikeli kuphela imishini yakho, kodwa futhi inikeza ikhwalithi yomsindo enhle kakhulu.

Ungalungisa inzuzo yeamplifier yakho ngokufanisa i-voltage yeyunithi yekhanda ephumayo ye-AC ne-voltage yokufaka ye-amplifier. Iphinde ivimbele ukunqunywa komsindo.

Ukuze usethe isilawuli sokuzuza, uzodinga okulandelayo:

I-multimeter yedijithali, izipikha, imanuwali yeamplifier yakho, isibali, ne-CD yesignali yokuhlola noma i-flash drive. Nansi imiyalelo yesinyathelo ngesinyathelo yokulungisa i-amplifier ngezindlela ezihlukahlukene.

Indlela yokusetha i-amplifier nge-multimeter?

Isinyathelo 1: Kala i-impedance yesipika nge-multimeter.

Hlola i-impedance yesipika. Uzobe uxhuma ku-amplifier usebenzisa i-multimeter yedijithali. Ukuze wenze lokhu, vala amandla esipika. Bese unquma ukuthi iyiphi itheminali kusipika ephozithivu nenegethivu. Xhuma i-red test lead kutheminali ephozithivu bese isivivinyo esimnyama siholele kutheminali enegethivu.

Bhala phansi ukumelana kuma-ohms okubonwa ku-multimeter. Khumbula ukuthi ukuvimbela okukhulu kwesipikha kungu-2, 4, 8 noma 16 ohms. Ngakho, inani eliseduze kunani elirekhodiwe lingaqashelwa ngokuzethemba.

Isinyathelo sesi-2: Naka amandla okukhipha anconyiwe we-amplifier.

Thatha imanuwali yomsebenzisi ye-amplifier futhi uthole amandla anconyiwe okukhiphayo. Qhathanisa lokhu nokumelana nesipika sakho ngama-ohms.

Isinyathelo sesi-3: Bala i-voltage ye-AC edingekayo

Manje sidinga ukuthola i-voltage eqondiwe ye-amplifier. Lena i-voltage ephumayo lapho sidinga ukusetha inzuzo ye-amplifier. Ukuze siyibale, sidinga ukusebenzisa okuhlukile komthetho ka-Ohm, V = √ (PR), lapho u-V eyi-voltage ye-AC eqondiwe, u-P amandla, no-R ukumelana (Ω).

Ake sithi imanuwali yakho ithi i-amplifier kufanele ibe ngama-watts angu-500, futhi i-impedance yesipika sakho, oyithole nge-multimeter, ingu-2 ohms. Ukuze uxazulule isibalo, phindaphinda ama-watts angu-500 ngo-2 ohms ukuze uthole u-1000. Manje sebenzisa isibali ukuze uthole impande eyisikwele engu-1000 futhi amandla akho okukhipha amandla kufanele abe ngu-31.62V esimweni sokulungiswa kwenzuzo yobumbano.

Uma une-amplifier enezilawuli ezimbili zokuzuza, zizocutshungulwa ngokuzimela.

Isibonelo, uma i-amplifier inama-watts angu-200 eziteshini ezine, sebenzisa amandla okukhipha isiteshi esisodwa ukuze ubale i-voltage. I-voltage yokulawula inzuzo ngayinye iyimpande yesikwele yama-watts angu-200 x 2 ohms.

Isinyathelo 4 Khipha Zonke Izinsiza

Nqamula zonke izinsiza ezengeziwe, okuhlanganisa izipikha nama-subwoofers, ku-amplifier ngaphansi kokuhlolwa. Nqamula kuphela amatheminali aphozithivu ukuze ukhumbule isilungiselelo lapho udinga ukuwaxhuma futhi.

Isinyathelo sesi-5: Ukusetha i-Equalizer ku-Zero

Khubaza isilinganisi noma usethe zonke izilungiselelo zaso ezifana nevolumu, i-bass, i-treble, ukucubungula, i-bass boost kanye nemisebenzi yesilinganisi ibe yiziro. Lokhu kuvimbela amaza omsindo ukuthi ahlungwe ngakho-ke kukhulisa ububanzi bomkhawulokudonsa.

Isinyathelo sesi-6: Setha i-Gain ibe nguziro

Kuma-amplifiers amaningi, ukulungiselelwa okuncane kufinyelelwa ngokuphendula ukudayela ngokuphambene newashi kuze kufike lapho kuzohamba khona.

Izinyathelo 4, 5 kanye no-6 zishiya i-amplifier ixhunywe kugesi kuphela.

Isinyathelo sesi-7: Setha ivolumu ibe ngu-75%

Vula iyunithi yekhanda ku-75% wevolumu ephezulu. Lokhu kuzovimbela imisindo ehlanekezelwe yesitiriyo ukuthi ingathunyelwa ku-amplifier.

Isinyathelo sesi-8 Dlala Ithoni Yokuhlola

Ngaphambi kokuthi uqhubeke, qiniseka ukuthi isipikha sinqanyuliwe ku-amplifier.

Manje udinga iringithoni yokuhlola ukuhlola isistimu yakho. Dlala isignali yokuhlola kusistimu ye-stereo ene-sine wave yayo ku-0 dB. Umsindo kufanele ube nemvamisa engu-50-60 Hz ye-subwoofer amplifier kanye nobude begagasi obungu-100 Hz ku-mid-range amplifier. Ingadalwa ngohlelo olufana ne-Audacity noma ilandwe ku-inthanethi. (1)

Faka iyunithi yekhanda ukuze umsindo udlalwe ngokuqhubekayo.

Isinyathelo sesi-9: Xhuma i-Multimeter ku-Aplifier

Setha i-DMM ku-AC voltage bese ukhetha ububanzi obuqukethe i-voltage eqondiwe. Xhuma i-multimeter eholela ezimbobeni zokuphuma kwezipikha ze-amplifier. I-probe enhle ye-multimeter kufanele ifakwe ku-terminal eqondile, futhi i-negative probe ye-multimeter kufanele ifakwe ku-terminal negative. Lokhu kukuvumela ukuthi ulinganise i-voltage ye-AC ku-amplifier.

Uma i-voltage ephuma ngokushesha ephumayo eboniswa ku-multimeter ingaphezu kuka-6V, phinda izinyathelo 5 no-6.

Isinyathelo 10: Lungisa I-Gain Knob

Kancane kancane vula i-knob ye-amplifier ngenkathi ubheka ukufundwa kwamandla kagesi ku-multimeter. Misa ukulungisa i-knob ngokushesha nje lapho i-multimeter ikhombisa i-voltage ye-AC ehlosiwe oyibale ngaphambilini.

Siyakuhalalisela, uyilungise kahle inzuzo ku-amplifier yakho!

Isinyathelo 11: Phindela amanye ama-amps

Usebenzisa le ndlela, lungisa wonke ama-amplifiers ohlelweni lwakho lomculo. Lokhu kuzokunikeza umphumela obuwufuna - okungcono kakhulu.

Isinyathelo 12: Setha ivolumu ku-zero.

Yehlisa ivolumu kuyunithi yekhanda ibe ziro futhi uvale isistimu ye-stereo.

Isinyathelo 13: Xhuma yonke into emuva

Xhuma kabusha zonke izesekeli njengoba ubungenza ezinye izikhulisa-zwi nezipikha; ukhiphe ngaphambi kokufaka inzuzo. Qiniseka ukuthi zonke izintambo zixhunywe ngendlela efanele futhi uvule iyunithi yekhanda.

Isinyathelo 14: Jabulela Umculo

Susa ingoma yokuhlola kusitiriyo sakho futhi udlale eyodwa yezingoma zakho eziyintandokazi. Zizungeze ngomculo onokhahlo futhi ujabulele ukuhlanekezelwa okuphelele.

Ezinye izindlela zokulungisa i-amplifier

Ungalungisa inzuzo ye-amp yakho kanye ne-bass boost ngokuyilungisa mathupha futhi ulalele lokho okuzwakala kahle kakhulu. Kodwa le ndlela ayinconywa ngoba sivame ukuhluleka ukubamba ukuhlanekezela okuncane kakhulu.

isiphetho

Ukusebenzisa i-multimeter yedijithali ukulungisa inzuzo kungenye yezindlela eziphumelela kakhulu nezilula. Lokhu kukuvumela ukuthi usethe inzuzo cishe kuwo wonke ama-amplifiers. Indlela engcono kakhulu yokuvimbela noma yikuphi ukuhlanekezela ohlelweni lwakho ukusebenzisa i-oscilloscope. Ithola ngokunembile konke ukusika nokuhlanekezela. (2)

Nge-multimeter engcono kakhulu esandleni, sethemba ukuthi lo mhlahlandlela uzokusiza ukusetha i-amplifier yakho kahle.

Ungaphinda uhlole futhi ufunde amanye amamanuwali usebenzisa i-multimeter engakusiza ngokuzayo. Izihloko ezimbalwa zifaka: Indlela yokuhlola i-capacitor nge-multimeter nokuthi Ungahlola kanjani ibhethri nge-multimeter.
