Maitiro ekugadzirisa Mota Amplifier yeMids uye Highs (Nhungamiro ine Mifananidzo)

19.02.2023 /

Muchinyorwa chino, ini ndichakudzidzisa nzira yekumisikidza mota amplifier yepakati uye yakakwirira frequencies mumaminetsi mashoma.

Kukanganiswa kweaudhiyo kunoitika kana iyo yekudzora frequency yakasetwa yakanyanya. Semunhu mukuru westereo hobbyist aishanda muchitoro chestereo chemota, ndine ruzivo rwekugadzirisa maamplifiers kuti ndivandudze ruzha. Iwe unogona kubvisa kukanganisa mu stereo yako nekugadzirisa zvakanaka mids uye trebles ine treble uye bass marongero. Iwe zvakare unodzivirira kukanganisa kwekurira kunokuvadza vatauri uye zvimwe zvikamu zve stereo system, uye haungaite kurasikirwa kana imwe mari yekugadzirisa yako odhiyo system.

Kurumidza Kutarisisa: Aya anotevera matanho anozonyatso gadzirisa mota yako amplifier yepakati uye yakakwirira:

  • Kuridza odhiyo yako yaunofarira kana mimhanzi
  • Tsvaga iyo yekuwana control kuseri kweamplifier uye woitendeudzira yakananga pakati.
  • Rongedza vhoriyamu kusvika pa75 muzana
  • Dzorera iyo yekuwana kutonga uye zvishoma nezvishoma kuwedzera kuwanda kusvika zviratidzo zvekutanga zvekukanganisa zvionekwe.
  • Iwe unogona zvakare kushandisa multimeter kugadzirisa kuwana kutonga.
  • Flip iyo HPF switch pane amplifier uye isa iyo HPF ku80Hz kuseta yakakwirira ma frequency.
  • Gadzirisa ma frequency ari pakati pe59 Hz ne60 Hz kuti uwane ruzha rwakanyanya kunaka.
  • Bvisa hutsinye hwepamusoro uye dips neamp's EQ control.

Pazasi ini ndichapinda mukati meizvi.

Kugadzirisa ma frequency epakati uye akakwira

Iyo amplifier kuseta zvakare zvinoenderana nerudzi rweamplifier mumotokari yako stereo. Vanotangisa vanofanirwa kuve nechokwadi chekuti hapana yakaderera frequency padyo nevatauri vavo.

Zvakare, iwe unoda yakakodzera Gain kuseta kuti uwane iyo chaiyo ipf uye hpf yema mods uye maxes. Dzivisa kukanganisa, kunyange zvazvo inogona kuderedzwa kana kubviswa nyore nyore. Kukanganisa kunogona kukonzera kukanganisa kusinga taurike kune vatauri nenzeve dzako. Kukanganisa kunoitika kana iwe ukaisa iyo yekuwana yekudzora zvakanyanya uye ipapo amplifier inotumira akachekwa odhiyo masaini kune vatauri. Mimhanzi ine ruzha inoita kuti zvinhu zvitonyanya kuipa nekuti maspeakers anenge atoremerwa.

Maitiro ekuseta kuwana control

Kuti uite izvi:

vanotsika 1. Ridza rwiyo rwaunoziva nokuti unoziva kuti runonzwika sei.

Pane amp, tsvaga iyo Gain knob woitenderedza ingangoita hafu yenzira - usaise kusimba rakazara.

vanotsika 2. Shandura vhoriyamu kusvika pamakumi manomwe neshanu muzana - kukanganisa kunotanga pamavhoriyamu akanyanya, saka usaise vhoriyamu kusvika pakakwirira.

vanotsika 3. Teerera mumhanzi uri kuridzwa uone kana wakanaka.

vanotsika 4. Dzokera kune kuwana kutonga kumashure kweamplifier uye gadzirisa (zvakaoma) kusvikira kukanganisa kwatanga. Rega kukwidza vhoriyamu kana wangoona kukanganiswa.

Neimwe nzira, unogona kushandisa multimeter kugadzirisa kutonga kwekuwana.

Kuisa the maximums

Kana iwe uchida chete ma frequency epamusoro muvatauri vako, saka HPF yakakwira pass sefa ndiyo yaunoda. Iyo HPF inovhara yakaderera frequency masiginecha ayo asina kunyatso kuburitswa nevatauri uye ma tweeters. Low frequency masaini anogona kupisa vatauri vako, saka HPF inobatsira kudzivirira izvi.

Matanho anotevera achakubatsira iwe kurongedza treble:

Danho 1: Flip iyo Hpf switch pane amplifier, kana shandisa screwdriver kuigadzirisa kana pasina switch pairi.

Kuti uvhure zvigadziriso, shandura iyo yakakwirira pass filter switch pane yako amplifier. Mazhinji amps ane switch, asi zvinoenderana neOEM.

Danho rechipiri: Isa iyo High Pass Sefa ku2Hz

HPFs vanoona maitiro avo ekugadzirisa kubva pa80Hz kusvika 200Hz, asi yekutanga ndiyo yakanyanya kunaka.

Chero frequency pazasi 80Hz inofanirwa kuendeswa kune subwoofer uye bass speaker. Mushure mekuisa iyo HPF ku80Hz, gadzirisa iyo LPF kutora ma frequency pazasi 80Hz. Saka, iwe unobvisa mikaha mukugadzirwa kwezwi - hapana frequency inosiiwa isina kutariswa.

Kuisa ma frequency epakati

Vanhu vazhinji vanondibvunza kuti ndeipi frequency kuseta yakanakira yepakati mafrequency. Apa chienda!

Danho 1: Gadzirisa pakati pakati pe50Hz ne60Hz.

Izvo zvakakosha zvakanyanya kuyeuka kuti avhareji frequency yemutauri mukuru wemota iri pakati pe50 Hz ne60 Hz. Nekudaro, mamwe maaudiophiles anoshandisa maequalizer kune akanyanya kujeka kuravira. Saka, tsvaga iyo midrange knob pane amp woisa ku50Hz kana 60Hz.

Danho 2: Bvisa nhongonya dzakapinza uye dips

Kuti uite izvi, shandisa modulation kana equalizer marongero. Akapinza peaks uye dips anogadzira manzwi akashata, saka ive shuwa yekuabvisa neako amp's EQ marongero. (1)

Equalizer marongero zvakare anopatsanura ruzha kuita yakaderera, yepakati uye yakakwirira frequency. Izvi zvinokutendera kuti uzvigadzirise sezvaunoda; zvisinei, vamwe vanosarudza kushandisa Anwendung tune ari amplifier. Asi kazhinji iwe unofanirwa kuseta zvakakwirira zvishoma pane mids kune yakanakisa ruzha.

Chekupedzisira, kana uchimisikidza amplifier marongero, ita shuwa kuti anoenderana nezvido zvako. Vanhu vane zvavanofarira zvakasiyana muruzha, uye zvinonzwika zvakanaka kwauri zvinogona kunge zvisina kunaka kune mumwe munhu. Iko hakuna yakaipa kana yakanaka ruzha kana amplifier marongero; Nyaya yacho ndeyokubvisa kukanganisa.

Basic mazwi uye amplifier marongero

Izvo zvinodikanwa kuti unzwisise mazwi ekutanga uye maitiro ekumisikidza mota amplifier usati wagadzirisa mids uye yakakwirira. Zvinosiyana zvakaita semumhanzi uri kuridzwa, mutauri, kana hurongwa hwese hunokanganisa pakati nepamusoro frequency tuning.

Mukuwedzera, kune akati wandei mabhatani kana marongero kumashure kweamplifier inoda ruzivo rwakanaka rweamplifier. Zvikasadaro, unogona kuvhiringika kana kukanganisa marongero. Pazasi ini ndichakurukura pfungwa huru zvakadzama.

frequency

Frequency ndiyo nhamba yekutenderera pasekondi, kuyerwa muHertz, Hz. [1 Hertz == 1 kutenderera pasekondi]

Pamafaro epamusoro, masaini masaini anoburitsa manzwi akakwira. Naizvozvo, frequency chinhu chakakosha chepakati uye yakakwira frequency mune odhiyo kana mimhanzi.

Bass inosanganiswa nebass, uye iwe unofanirwa kuve uine bass vatauri kuti unzwe yakaderera frequency. Zvikasadaro, low frequency radio waves inogona kukuvadza vamwe vatauri.

Kusiyana neizvi, mafrequency akakwira anogadzirwazve nezviridzwa zvakaita semakwakwakwa esimba nemimwe michina yakakwira-frequency. Nekudaro, isu hatigone kunzwa ese ma frequency - frequency renji yezeve ndeye 20 Hz kusvika 20 kHz.

Mamwe ma frequency units mumotokari amplifiers

Vamwe vagadziri vanonyora frequency muma decibels (dB) eLPF, HPF, super bass, zvichingodaro.

Gain (input sensitivity)

Gain inotsanangura kunzwisiswa kweamplifier. Iwe unogona kuchengetedza yako stereo system kubva pakukanganiswa kweodhiyo nekugadzirisa kuwana zvinoenderana. Nekudaro, nekugadzirisa kuwana, iwe unowana yakawedzera kana kushoma vhoriyamu pakuiswa kweiyo amplifier. Ukuwo, vhoriyamu inongokanganisa kubuda kwemutauri.

Masetirwo epamusoro anounza ruzha pedyo nekukanganiswa. Mune iyi vheji, iwe unofanirwa kukwenenzvera zvigadziriso zvekuwana kuti ubvise kukanganisa pakubuda kwemutauri. Iwe unozoona kuti mutauri anongopa simba rakakwana rekubvisa kukanganiswa kweodhiyo.

Crossovers

Crossovers inova nechokwadi chekuti chiratidzo chakakodzera chinosvika mutyairi akakodzera. Ichi chigadziriso chemagetsi chakavakirwa mukati memotokari inonzwika sedunhu kuti iparadzanise frequency yekuteerera muzvikamu zvakasiyana. Imwe neimwe frequency renji inoendeswa kune akakodzera mutauri - tweeters, subwoofers uye woofers. Iwo ma tweeters anogashira ma frequency epamusoro, nepo subwoofers uye woofers vachigamuchira yakaderera frequencies.

High Pass Filters

Vanodzikamisa mafrequency anopinda mumaspeaker kune mafrequency akakwira chete - kusvika kune imwe muganhu. Saizvozvo, low frequency inovharika. Saka, mafirita epamusoro-soro haashande nema tweeters kana matauriro madiki anogona kukuvadzwa kana masaini epasi-frequency achipfuura nepasefa.

Low Pass Filters

Masefa epasi pasi ndiwo anopesana nemasefa epamusoro. Ivo vanokutendera kuti utumire akadzika ma frequency (kusvika kune imwe muganho) kune subwoofers uye woofers - bass speaker. Uye zvakare, ivo vanosefa kunze ruzha kubva kune masaini masaini, vachisiya yakatsetseka bass masaini kumashure.

Summing up

Kugadzirisa amplifier yemotokari yepakati uye yakakwirira frequencies haina kuoma. Nekudaro, iwe unofanirwa kunzwisisa izvo zvakakosha zvikamu kana zvinhu zveodhiyo tuning - frequency, crossovers, kuwana kutonga, uye kupfuura mafirita. Nemumhanzi waunofarira uye ruzivo rwakakwana, unogona kuwana zvinofema zvinonzwika mune yako stereo system. (2)
