Zviri mukati

Method 1 - Manual setup
Nzira 2 - Shandisa Distortion Detector
Nzira 3 - Shandisa oscilloscope

Kumisikidza 4-channel amplifier kunogona kuve kwakaoma. Hedzino nzira nhatu dzinogona kugadzirisa zvese.

Kunyatso kumisa 4-channel amplifier kune akawanda mabhenefiti. Hunhu hwakanaka hwekurira, hupenyu hwemutauri hurefu uye kubvisa kukanganisa ndezvimwe zvacho. Asi kune vanotanga, kumisikidza amplifier inogona kunge isina kuongororwa nekuda kwekuoma kwemaitiro. Saka, ini ndichakudzidzisa nzira nhatu dzakasiyana dzekumisikidza 4-channel amplifier pasina kuparadza mota yako yekuteerera.

Kazhinji, kumisikidza 4-channel amplifier, tevera nzira nhatu idzi.

Method 1 - Manual setup

Iyo yemanyorero tuning process inogona kunge iri yakanakisa sarudzo kana iwe uchitsvaga nekukurumidza kuseta. Kuti uite izvi, iwe unongoda flathead screwdriver. Uye iwe unofanirwa kukwanisa kuona kukanganisa nekungoteerera.

Nhanho 1 Dzima kuwana, mafirita uye zvimwe zvinokonzeresa.

Chekutanga pane zvese, gadzirisa iyo amplifier kuwana kune iyo shoma. Uye ita zvimwechete kune yakaderera uye yakakwirira pass filters. Kana iwe uri kushandisa yakakosha mhedzisiro senge bass boost kana treble boost, vadzima.

Ita shuwa yekudzima zviri pamusoro apa mumusoro unit futi. Chengetedza kuwanda kwechikamu chemusoro pa zero.

Nhanho 2 - Dhonza kumusoro uye pasi vhoriyamu pamusoro wako unit

Wobva wawedzera zvishoma nezvishoma vhoriyamu yemusoro uye wotanga kuridza rwiyo rwunozivikanwa. Wedzera inzwi kusvika wanzwa kukanganisa. Wobva wadzora vhoriyamu pasi nhanho imwe kana maviri kusvika kukanganisa kwabviswa.

Nhanho 3 - Wedzera uye kuderedza kuwana mune amplifier

Zvino tora flathead screwdriver uye tsvaga kuwana knob pane amp. Zvinyoro shandura bundu rekuwedzera kusvika wanzwa kukanganisa. Paunonzwa kukanganisa, shandura knob counterclockwise kusvikira wabvisa kukanganisa.

Ramba uchifunga: Rwiyo runofanira kuridza zvakanaka mumatanho 3 ne4.

Nhanho 4. Bvisa bass boost uye gadzirisa mafiritsi.

Wobva washandura bass boost knob kusvika zero. Kushanda nebass boost kunogona kunetsa. Saka gara kure nebass boost.

Wobva waisa yaidiwa yakaderera uye yakakwirira pass sefa frequency. Aya ma frequency anogona kusiyana zvichienderana ne subwoofers uye tweeters anoshandiswa.

Nekudaro, kuseta iyo yakaderera pass sefa kusvika 70-80 Hz uye iyo yakakwirira pass sefa kusvika 2000 Hz zvine musoro (rudzi rwemutemo wechigunwe).

Danho 5 - Dzokorora

Dzokorora nhanho 2 uye 3 kusvikira wasvika pavhoriyamu pamwero we80%. Ungangoda kudzokorora maitiro 2 kana 3 nguva.

Yako 4 chiteshi amplifier ikozvino yakagadzirirwa nemazvo.

zvakakosha: Kunyangwe manyorerwo ekugadzirisa ari nyore, vamwe vanogona kunetseka kuona kukanganisa. Kana zvakadaro, shandisa imwe yenzira mbiri dziri pasi apa.

Nzira 2 - Shandisa Distortion Detector

Iyo distortion detector chishandiso chikuru chekugadzirisa ina-channel amplifier. Pano unogona kudzidza kuishandisa.

Nhanho 1 Dzima kuwana, sefa uye zvimwe zvinokonzeresa.

Chekutanga, dzima marongero ese, senge nzira 1.

Nhanho 2 - Batanidza masensa

Iyo distortion detector inouya nemasensa maviri. Vabatanidza kune zvinobuda zvemutauriri weamplifier.

Nhanho 3 - Gadzirisa Head Unit Vhoriyamu

Zvadaro wedzera huwandu hwemusoro wemusoro. Uye panguva imwe chete, tarisa kukanganisa detector LED zviratidzo. Iyo tsvuku yepamusoro ndeyekukanganisa. Saka, kana mudziyo ukaona chero kukanganisa, mwenje mutsvuku unobatidzwa.

Panguva ino, mira kuwedzera vhoriyamu uye kuderedza vhoriyamu kusvika mwenje dzvuku wadzima.

Nhanho 4 - Gadzirisa Kuwana

Tevedza iwo maitiro akafanana ekukwidziridza amplifier semudanho rechitatu (wedzera uye kudzikisira kuwana zvinoenderana nekukanganisa). Shandisa screwdriver kugadzirisa iyo amplification musangano.

Nhanho 5 - Gadzirisa mafirita

Gadzirisa mafirita epasi uye akakwira kune iwo chaiwo ma frequency. Uye dzima bass boost.

Danho 6 - Dzokorora

Dzokorora nhanho 3 uye 4 kusvika wasvika 80% vhoriyamu pasina kukanganisa.

Nzira 3 - Shandisa oscilloscope

Kushandisa oscilloscope ndiyo imwe nzira yekumhanyisa mana-channel amplifier. Asi maitiro aya akati omei.

Nhanho 1 Dzima kuwana, sefa uye zvimwe zvinokonzeresa.

Chekutanga, dzima kuwana, sefa, uye zvimwe zvakakosha zveamplifier. Ita zvakafanana kune musoro wepamusoro. Isawo head unit volume kusvika zero.

Danho 2 - Dzima vatauri vese

Wobva wabvisa vese vatauri kubva kune amplifier. Munguva iyi yekuseta, unogona kukuvadza vatauri vako netsaona. Nokudaro, vachengete vakaremara.

Nhanho 3 - Batanidza yako smartphone

Tevere, batanidza yako smartphone kune ebetsero mapipu eiyo musoro unit. Shandisa yakakodzera Aux-In tambo kune izvi. Wobva waridza toni yebvunzo. Nekuita uku, ini ndinosarudza toni yekuyedza ye1000 Hz.

Cherechedza: Usakanganwa kubatidza head unit panguva ino.

Nhanho 4 - Gadzira oscilloscope

Iyo oscilloscope yakagadzirirwa kuratidza girafu yechiratidzo chemagetsi. Pano unogona kutarisa voltage graph. Asi nokuda kweizvi, iwe unofanira kutanga wagadzirira zvakanaka oscilloscope.

An oscilloscope yakafanana chaizvo nedhijitari multimeter. Panofanira kunge paine maprobe maviri; Tsvuku uye dema. Batanidza iyo tsvuku inotungamira kuVΩ chiteshi uye dema inotungamira kune COM port. Wobva watendeutsa dial kune AC voltage marongero.

Tapota cherechedza: Kana zvichidikanwa, gadzirisa mafirita epasi uye akakwira usati watanga nhanho yechishanu. Uye dzima bass boost.

Nhanho 5 Batanidza sensor kune zvinobuda mutauri.

Zvino batanidza oscilloscope probes kune zvinobuda mutauri.

Mune iyi 4-channel amplifier, maviri chiteshi akatsaurirwa kune vaviri vatauri vepamberi. Uye mamwe maviri ndeevatauri vekumashure. Sezvauri kuona, ndakabatanidza ma probe kune imwe yekumberi chiteshi.

Mazhinji oscilloscopes ane default mode uye anoratidza manhamba (voltage, yazvino, uye kuramba). Asi iwe unoda girafu mode. Saka, tevera matanho aya.

Bata pasi bhatani reR kwemasekonzi maviri kana matatu (pasi pebhatani reF2).

Gadzirisa kunzwisiswa kwegirafu nebhatani reF1.

Nhanho 6 - Wedzera vhoriyamu

Mushure mezvo simudza vhoriyamu yemusoro weyuniti kusvika kumusoro nepasi kwechiratidzo kwati sandara (chiratidzo ichi chinozivikanwa sechiratidzo chakachekwa).

Wobva wadzikisa vhoriyamu kusvika wawana waveform yakajeka.

Iyi ndiyo nzira yaunogona kubvisa nayo kukanganisa uchishandisa oscilloscope.

Nhanho 7 - Gadzirisa Kuwana

Iye zvino unogona kugadzirisa iyo amplifier kuwana. Kuti uite izvi, isa ma sensor maviri pane imwechete yekumberi chiteshi sepadanho 6.

Tora flathead screwdriver uye shandura iyo amplifier kuwana kudzora wachi. Iwe unofanirwa kuita izvi kusvikira oscilloscope ichiratidza chiratidzo chakadimburwa. Wobva watendeutsa nod counterclockwise kusvika wawana yakajeka waveform.

Dzokorora nhanho 6 uye 7 kana zvichidikanwa (edza kuwana kanenge 80% vhoriyamu pasina kukanganisa).

Nhanho 8 - Gadzira machaneli ekumashure

Tevedza nhanho dzakafanana senhanho 5,6, 7, 4 uye XNUMX kumisikidza nzira dzekumashure. Edzai chiteshi chimwe nechimwe chemberi nekumashure. Yako XNUMX chiteshi amplifier ikozvino yakagadzirirwa uye yagadzirira kushandisa.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.
