Nzira yekugadzira amplifier ine multimeter

Mimhanzi ine simba uye yakanaka ruzha system inoita kuti ive nani. Wana zvakanyanya kubva mumotokari yako stereo uye odhiyo system nekunyatso gadzirisa amplifier yako ine multimeter. Iyo haingo chengetedza midziyo yako chete, asiwo inopa yakanakisa ruzha rwemhando.

Iwe unogona kugadzirisa kuwana kweamplifier yako nekufananidza iyo musoro unit's AC inobuda voltage kune iyo amplifier yekupinza voltage. Iyo inodzivirirawo kuderedzwa kweaudio.

Kuti ugadzire iyo gain control, iwe uchada zvinotevera:

Digital multimeter, vatauri, yako amplifier manual, Calculator, uye bvunzo chiratidzo CD kana flash drive. Heano nhanho-nhanho mirairo yekugadzirisa amplifier nenzira dzakasiyana.

Nzira yekugadzira amplifier ine multimeter?

Danho 1: Edza iyo mutauri impedance ine multimeter.

Tarisa kusagadzikana kwemutauri. Iwe uchave uchibatanidza kune amplifier uchishandisa dijitari multimeter. Kuti uite izvi, dzima simba kune mukurukuri. Woona kuti ndeipi terminal pamukurukuri iri positive uye iri negative. Batanidza iyo tsvuku bvunzo inotungamira kune yakanaka terminal uye dema bvunzo inotungamira kune iyo isina kunaka terminal.

Nyora pasi kushorwa mu ohms kunoonekwa pane multimeter. Rangarira kuti iyo yakanyanya mutauri impedance ndeye 2, 4, 8 kana 16 ohms. Nokudaro, kukosha kwepedyo kune kukosha kwakanyorwa kunogona kuonekwa nechivimbo.

Nhanho yechipiri: Teerera kune yakakurudzirwa kuburitsa simba reamplifier.

Tora yako amplifier's user manual uye tsvaga inokurudzirwa kuburitsa simba. Enzanisa izvi nekuramba kwemutauri wako muohms.

Danho rechitatu: Verenga inodiwa AC voltage

Iye zvino isu tinoda kutsvaga yakananga voltage yeamplifier. Iyi ndiyo voltage inobuda yatinoda kuseta kuwana kweamplifier. Kuiverenga, tinoda kushandisa mutsauko wemutemo waOhm, V = √ (PR), apo V ndiyo inonangwa AC voltage, P isimba, uye R ndiyo inopikisa (Ω).

Ngatitii bhuku rako rinoti amplifier inofanira kunge iri mazana mashanu watts, uye impedance yemutauri wako, iyo yawakawana ine multimeter, ndeye 500 ohms. Kugadzirisa equation, wedzera 2 watts ne 500 ohms kuti uwane 2. Iye zvino shandisa karukureta kuti uwane square root ye1000 uye yako inobuda voltage inofanira kuva 1000V munyaya yekubatana kuwana kugadzirisa.

Kana iwe uine amplifier ine maviri ekuwana ekudzora, iwo anozogadziriswa akazvimirira.

Semuyenzaniso, kana amplifier iine 200 watts kumachaneli mana, shandisa simba rekubuda reimwe chiteshi kuverenga voltage. Iwo magetsi ega ega ega ega ega kudzora ndiyo square root ye200 watts x 2 ohms.

Nhanho 4 Bvisa Zvese Zvishandiso

Bvisa zvese zvimwe zvekuwedzera, kusanganisira vatauri uye subwoofers, kubva kune amplifier pasi pekuyedzwa. Dhonza chete materminal ari positive kuitira kuti urangarire kuseta paunoda kuabatanidza zvakare.

Nhanho 5: Kuisa Equalizer kusvika Zero

Pamwe dzima iyo yakaenzana kana kuseta ese magadzirirwo ayo akadai sevhoriyamu, bass, treble, kugadzirisa, bass boost uye basa rekuenzanisa kusvika zero. Izvi zvinodzivirira masaisai eruzha kubva kusefa uye nekudaro anowedzera bandwidth renji.

Nhanho yechitanhatu: Isa Gain kune Zero

Kune akawanda amplifiers, iyo shoma yekuseta inowanikwa nekutenderedza dial counterclockwise kusvika painoenda.

Matanho 4, 5 uye 6 anosiya amplifier yakabatana kune magetsi chete.

Nhanho yechinomwe: Isa iyo vhoriyamu ku7%

Vhura chikamu chemusoro pa75% yehuwandu hwehuwandu. Izvi zvinodzivirira stereo yakakanganiswa manzwi kubva pakutumirwa kune amplifier.

Nhanho 8 Tamba Toni Yekuyedza

Usati waenderera mberi, ita shuwa kuti mutauri adzimwa kubva kune amplifier.

Iye zvino iwe unoda kuyedza ringtone kuti uedze system yako. Tamba chiratidzo chekuyedza pane stereo system ine sine wave pa0 dB. Ruzha runofanira kunge rwuine frequency ye50-60 Hz ye subwoofer amplifier uye wavelength ye100 Hz yepakati-renji amplifier. Inogona kugadzirwa nechirongwa chakadai seAudacity kana kutorwa kubva paInternet. (1)

Isa iyo head unit kuitira kuti ruzha rurambe ruchiridzwa.

Nhanho 9: Batanidza iyo Multimeter kune Amplifier

Gadzirisa iyo DMM kune AC voltage uye sarudza renji ine voltage yakanangana. Batanidza iyo multimeter inotungamira kune amplifier's speaker inobuda ports. Iyo yakanaka probe ye multimeter inofanira kuiswa muhutano hwakanaka, uye iyo isina kunaka probe ye multimeter inofanira kuiswa mumagetsi asina kunaka. Izvi zvinokutendera kuyera iyo AC voltage pane amplifier.

Kana iyo yekukurumidza kubuda voltage inoratidzwa pane multimeter yakakwira kupfuura 6V, dzokorora nhanho 5 uye 6.

Nhanho 10: Gadzirisa iyo Gain Knob

Zvishoma nezvishoma shandura iyo amplifier yekuwana knob uchitarisa kuverenga kwevoltage pane multimeter. Rega kugadzirisa knob nekukurumidza kana iyo multimeter ichiratidza chinangwa AC yekubuda voltage yawakaverenga kare.

Makorokoto, wakanyatso gadzirisa kuwana pane amplifier yako!

Nhanho 11: Dzokorora kune mamwe maamps

Uchishandisa iyi nzira, gadzirisa ese amplifiers mumhanzi system yako. Izvi zvinokupa mhedzisiro yawanga uchitsvaga - yakanyanya kunaka.

Nhanho 12: Isa vhoriyamu kusvika zero.

Deredza vhoriyamu yemusoro kusvika zero uye dzima stereo system.

Nhanho 13: Batanidza Zvese Kudzokera mukati

Batanidzazve zvese zvishongedzo sezvaungaita mamwe maamplifiers uye vatauri; iwe wakabvisa usati waisa kuwana. Ita shuwa kuti waya dzese dzakabatana nemazvo uye vhura iyo musoro unit.

Nhanho 14: Nakidzwa neMumhanzi

Bvisa tuni yebvunzo kubva kustereo yako uye ridza imwe yenziyo dzaunofarira. Zvikomberedze nenziyo dzinorwadza uye unakirwe nekukanganiswa kwakanaka.

Dzimwe nzira dzekugadzirisa amplifier

Iwe unogona kugadzirisa yako amp kuwana uye bass boost nekuigadzirisa nemaoko uye kuteerera kune zvinonzwika zvakanyanya. Asi nzira iyi haikurudzirwe nekuti isu kazhinji tinotadza kubata zvidiki zvakamonyaniswa.

mhedziso

Kushandisa dijitari multimeter kugadzirisa kuwana ndiyo imwe yenzira dzinoshanda uye dziri nyore. Izvi zvinokutendera kuti uise mukana kune angangoita ese amplifiers. Nzira yakanakisa yekudzivirira chero kukanganisa muhurongwa hwako kushandisa oscilloscope. Iyo inonyatsoona zvese kuchekwa uye kukanganisa. (2)

Iine yakanakisa multimeter paruoko, isu tinovimba gwara iri richakubatsira iwe kumisikidza amplifier yako nemazvo.

Iwe unogona zvakare kutarisa uye kuverenga mamwe mabhuku uchishandisa multimeter iyo inogona kukubatsira mune ramangwana. Zvishoma zvinyorwa zvinosanganisira: Maitiro ekuyedza capacitor ine multimeter uye Maitiro ekuyedza bhatiri ine multimeter.
