Nzira yekugadzira amplifier ine multimeter
Zviri mukati
Kunyangwe kuri mangwanani-ngwanani kutyaira kana rwendo rwehusiku, kuridza mimhanzi kubva kumota yako stereo ndeimwe yemitambo. manzwiro ari nani. Chii chinoita kuti zvinyanye kuve nani ndeye yakanaka ruzha sisitimu inokupa iwe zvese ruzha runofanira kupa.
Kuiswa kwakakodzera kwekuwana pane yako amplifier kuchakubatsira kuwana yepamusoro ruzha kunaka. Nekudaro, vanhu vazhinji havazive kuti amplifier chii uye havazive nhanho dzakaringana dzekugadzirisa kudzora kuwana.
Chinyorwa chino chinokuzivisa Zvese zvaunoda kuziva, kusanganisira nhanho-nhanho amp tuning neDMM chete. Ngatitangei.
Nei multimeter iri chishandiso chakakodzera?
Iyo inonziwo multitester kana volt-ohmmeter (VOM), multimeter chinhu chinoshandiswa kuyera huwandu hwemagetsi, ikozvino, uye kuramba huripo muchikamu chemagetsi. Iyo multimeter iri nyore kushandisa.
An amplifier, kune rumwe rutivi, mudziyo wemagetsi unoshandiswa kukwidziridza kana kuwedzera voltage, ikozvino, kana simba (amplitude) yechiratidzo kune imwe pfuma.
Chii chinonzi Amplifier Gain? Ingori chiyero cheamplitude kubva kune amplifier.
Iyi ndiyo nzira iyo multimeter uye amplifier zvinosangana pamwe chete. Amplifier tuning zvinongoreva kushandura amplitude level yevatauri vemota yako. Izvi zvinokanganisa kunaka kweinzwi rinobuda mumukurukuri uye, zvakare, ruzivo rwese rwekuteerera.
Iwe unogona chete kushandisa nzeve dzako kuona kuti aya masaini masaini ari kubuda zvakanaka sei. Nekudaro, iyi haisiriyo nzira yakanakisa yekuwana ruzha rwakanyanya, sezvo kukanganiswa kudiki kungangopotsa.
Apa ndipo panouya multimeter inobatsira.
Iyo dijitari multimeter inokuratidza iyo chaiyo yekusimudzira nhanho yeako masaini masaini.
Kwaunenge uine chaiwo kukosha kwauri kuvavarira nechiratidzo amplitude, multimeter inokutendera kuti uzviwane zviri nyore.
Pasinei nezvose izvi, hazvisi nyore sezvazvinoratidzika. Paunenge uchigadzira iyo amplifier, iyo voltage painopinza yemusoro unit inofanira kunge yakafanana neyekubuda kwayo. Izvi zvinoita kuti maaudio clippings adzivirirwe.
Zvino izvo zvekutanga zvakafukidzwa, ngatidzikei kubhizinesi.
Kugadzirisa amplifier ine multimeter
Mukuwedzera kune multimeter, iwe uchada mamwe maturusi. Izvi zvinosanganisira
- Amplifier test speaker
- Amplifier manual kuti udzidze zvakawanda nezvazvo
- Calculator yekuyera chaizvo huwandu hwekushushikana, uye
- CD kana imwe sosi inoridza ruzha pa60 Hz.
Ese ane mashandisiro azvo pakugadzirisa amplifier. Nekudaro, iwe zvakare uchashandisa formula. Ndiko kuti;
E = √PRapo E ndiyo AC voltage, P isimba (W) uye R ndiyo inopikisa (Ohm). Tevera matanho aya zvakanyatsonaka.
- Tarisa bhuku rekushandisa rinokurudzirwa simba rekubuda
Tarisa kubhuku remuridzi weamplifier kuti uwane ruzivo nezve simba rayo rekubuda. Hazvishanduke uye unoda kuzvinyora pasi usati waenderera mberi.
- Tarisa kusagadzikana kwemutauri
Resistance inoyerwa muohms (ohms) uye iwe unoda kurekodha ohms kuverenga kubva kumutauri. Iyi nzira iri nyore.
Zvese iwe zvunofanirwa kuita plug majoini muzvigadziko zvawo; iyo yekuverenga inobuda yekubatanidza inobatanidza kuVΩMa chinongedzo, uye dema rekubatanidza rinobatana neCOM yekubatanidza.
Kana izvi zvangoitwa, iwe unofambisa iyo multimeter yekusarudza kune "Ohm" logo (inowanzo inomiririrwa ne "Ω") uye ita shuwa kuti inoverenga 0 isati yatora chero mamwe matanho. Izvi zvinoratidza kuti zvinotungamirira zvinobatanidza hazvisi kubata.
Wave kubata zvinhu zvakafumurwa zvemasekete pamutauri nemapini aya. Apa ndipo paunoteerera kune ohm kuverenga pane multimeter.
Kupokana ukoshi muohms kuchinjika kutenderedza 2 ohms, 4 ohms, 8 ohms uye 16 ohms. Heino gwara rekuyera mutauri impedance.
- Verenga Target AC Voltage
Apa ndipo panopinda fomula yataurwa pamusoro apa. Iwe unoda kuona iyo yakananga voltage uchishandisa yakakurudzirwa amplifier simba uye mutauri impedance tsika dzawacherekedza pasi.
Apa ndipo paunoisa kukosha mufomula.
Semuyenzaniso, kana yako amplifier inobuda iine mazana matatu watts uye iyo impedance iri gumi nembiri, chaunovavarira AC voltage (E) ichave makumi matanhatu (square mudzi we (300(P) × 12(R); 60).
Iwe unozoona kubva pane izvi kuti kana iwe uchigadzirisa amplifier yako, iwe unoda kuve nechokwadi chekuti multimeter inoverenga makumi matanhatu.
Kana iwe uine amplifiers ane akawanda kuwana ekutonga, iwo maverengero anofanirwa kuiswa mufomura yakazvimirira.
Iye zvino kune matanho anotevera.
- Bvisa waya dzebetsero
Waona iyo yakananga voltage, unoenderera mberi nekubvisa zvese zvishandiso kubva kune amplifier. Izvi zvinosanganisira vatauri uye subwoofers.
Imwe muromo ndeyekubvisa chete materminal akanaka. Izvi zvinokutendera kuti uzive kwekuvabatanidza zvakare mushure mekupedza maitiro ese.
Usati waenderera, ita shuwa kuti vatauri vakabviswa zvachose kubva kune amplifier.
- Shandura zviyero kusvika zero
Iye zvino iwe unoisa ese akaenzana kukosha kune zero. Nekutenderedza mapfumo ekuwana paari pasi (kazhinji anopikisa-wachi), iwe unowana iyo yakanyanya bandwidth renji.
Equalizers anosanganisira Bass, Bass Boost Treble, uye Loudness, pakati pevamwe.
- Seta iyo head unit volume
Kuti uchengetedze zvinobuda zvestereo zvakachena, unoisa musoro wako unit kusvika 75% yehuwandu hwehuwandu.
- Play toni
Uku ndiko kubuda kweodhiyo kubva kuCD kana imwe sosi yekuisa iyo yaunoshandisa kuyedza uye kugadzirisa yako amplifier.
Chero ipi yekuisa sosi yaunoshandisa, iwe unofanirwa kuve nechokwadi chekuti toni yako sine wave iri pa0dB. Inzwi rinofanirawo kuva pakati pe50Hz ne60Hz yesubwoofer uye pa100Hz yepakati-renji amplifier.
Chengetedza inzwi muchiuno.
- Gadzirisa amplifier
Iyo multimeter inoshandiswa zvakare. Iwe unobatanidza zvibatanidza kune amplifier's speaker ports; pini yakanaka inoiswa pachiteshi chakanaka uye pini isina kunaka inoiswa pachiteshi chisina kunaka.
Iye zvino iwe unoshandura zvishoma nezvishoma iyo amplifier's gain control kusvika iwe wasvika kune chinangwa AC voltage yakanyorwa mudanho 3. Kana izvi zvangoitwa, amplifier yako ichave yakabudirira uye nemazvo.
Ehe, kuve nechokwadi chekuti ruzha kubva kune yako gudzanzwi rakachena sezvinobvira, unodzokorora izvi kune ako ese maamps.
- Reset head unit volume
Pano iwe unoshandura vhoriyamu yemusoro weuniti kusvika ku zero. Inourayawo stereo.
- Batanidza zvese zvishandiso uye unakirwe nemimhanzi
Zvese zvishongedzo zvakadimburwa mudanho rechina zvinozobatanidzwazve kune yavo materminals. Mushure mekuita chokwadi chekuti zvese zvinongedzo zvakabatana zvakanaka, iwe unowedzera huwandu hwemusoro weuniti uye wovhura mimhanzi yaunoda kuteerera.
Migumisiro
Iwe unogona kuona kubva pamatanho ari pamusoro kuti yako amp setup inoita senge hunyanzvi. Nekudaro, kuve nemultimeter inobata kunokupa iwe kuverenga kwakaringana kunokupa iwe ruzha rwakanyanya.
Kunze kwekushandisa nzeve dzako zvisina kuvimbika, dzimwe nzira dzekubvisa kukanganisa dzinosanganisira kushandisa oscilloscope.
Kana matanho ese aya akatinetsa kutevedzera, vhidhiyo iyi inogona kukubatsira.
