Ungashuna Kanjani Isihlelamsindo Semoto seMids kanye Nokuphakama (Umhlahlandlela onezithombe)

Kulesi sihloko, ngizokufundisa indlela yokusetha i-amplifier yemoto yamafrikhwensi aphakathi nendawo aphezulu ngemizuzu embalwa.

Ukuhlanekezelwa komsindo kwenzeka uma ifrikhwensi yokulawula inzuzo isethwe phezulu kakhulu. Njengomuntu omkhulu wokuzilibazisa we-stereo obesebenza esitolo se-stereo sezimoto, nginolwazi lokushintsha izikhulisamsindo ukuze ngithuthukise ikhwalithi yomsindo. Ungakwazi ukuqeda ukuhlanekezela kusitiriyo sakho ngokulungisa kahle ama-mids nama-trebles ngezilungiselelo ze-treble ne-bass. Uzophinda ugweme ukuhlanekezela komsindo okulimaza izipikha nezinye izingxenye zesistimu ye-stereo, futhi ngeke uhlangabezane nokulahlekelwa noma izindleko ezengeziwe zokulungisa isistimu yakho yomsindo.

Ukubuka Konke Okusheshayo: Izinyathelo ezilandelayo zizoshuna kahle isikhulisi semoto yakho phakathi nokuphakama:

• Idlala umsindo owuthandayo noma umculo
• Thola isilawuli sokuzuza ngemuva kwe-amplifier bese usibhekisa phakathi nendawo.
• Lungisa ivolumu ibe ngamaphesenti angaba ngu-75
• Buyisela isilawuli sokuzuza futhi kancane kancane wandise imvamisa kuze kuvele izimpawu zokuqala zokuhlanekezela.
• Ungasebenzisa futhi i-multimeter ukulungisa isilawuli sokuzuza.
• Phenya iswishi ye-HPF kuamplifier bese usetha i-HPF iye ku-80Hz ukuze usethe amaza aphezulu.
• Lungisa amaza amaphakathi phakathi kuka-59 Hz no-60 Hz ukuze uthole umsindo ongcono kakhulu.
• Susa iziqongo ezinzima kanye nokucwiliswa ngokulawula kwe-EQ ye-amp.

Ngezansi ngizojula kulokhu.

Ukulungisa amaza amaphakathi naphezulu

Ukulungiselelwa kwe-amplifier nakho kuncike ohlotsheni lwe-amplifier ku-stereo yemoto yakho. Abaqalayo kufanele baqinisekise ukuthi awekho amaza aphansi eduze kwezipikha zabo.

Futhi, udinga isilungiselelo esifanelekile se-Gain ukuze uthole i-ipf ne-hpf elungile yama-mods nama-max. Gwema ukuhlanekezela, nakuba kungase kuncishiswe noma kuqedwe kalula. Ukuhlanekezela kungabangela umonakalo omkhulu ezipikheni nasezindlebeni zakho. Ukuhlanekezela kwenzeka uma usetha isilawuli senzuzo sibe phezulu kakhulu bese isikhulisi sithumela amasiginali omsindo asikiwe kuzipikha. Umculo onomsindo wenza izinto zibe zimbi kakhulu ngoba vele izipikha sezigcwele kakhulu.

Indlela yokusetha ukulawulwa kwenzuzo

Ukwenza lokhu:

Isinyathelo 1. Dlala ingoma oyaziyo ngoba uyazi ukuthi izwakala kanjani.

Ku-amp, thola i-Gain knob bese uyiphendulela cishe phakathi nendawo - ungayisethi ibe namandla aphelele.

Isinyathelo 2. Guqula ivolumu ibe amaphesenti angu-75 - ukuhlanekezela kuqala kumavolumu aphezulu kakhulu, ngakho-ke ungasethi ivolumu ibe phezulu.

Isinyathelo 3. Lalela umculo odlalayo futhi ubone ukuthi muhle yini.

Isinyathelo 4. Buyela emuva ekulawuleni inzuzo ngemuva kwe-amplifier futhi uyilungise (kanzima) kuze kuqale ukuhlanekezela. Yeka ukunyusa ivolumu ngokushesha nje lapho ubona iminonjana yokuhlanekezela.

Kungenjalo, ungasebenzisa i-multimeter ukulungisa isilawuli sokuzuza.

Ukusetha ubukhulu

Uma ufuna amafrikhwensi aphezulu kuphela kuzipikha zakho, khona-ke isihlungi se-HPF ephezulu siyilokho okudingayo. I-HPF ivimba amasiginali aphansi akhiqizwa kabi izikhulumi nama-tweeter. Amasiginali wefrikhwensi ephansi angashisa izipikha zakho, ngakho i-HPF isiza ukuvikela lokhu.

Izinyathelo ezilandelayo zizokusiza ukuthi ushune i-treble:

Isinyathelo 1: Phenya iswishi ye-Hpf kuamplifier, noma sebenzisa i-screwdriver ukuze uyilungise uma ingekho iswishi kuyo.

Ukuze wenze izilungiselelo zisebenze, shintsha inkinobho yesihlungi se-high pass ku-amplifier yakho. Ama-amps amaningi anokushintsha, kepha kuya nge-OEM.

Isinyathelo sesi-2: Setha Isihlungi Se-High Pass sibe ngu-80Hz

Ama-HPF abona ukusebenza kwawo okuhle kakhulu kokucubungula kusuka ku-80Hz kuya ku-200Hz, kodwa eyangaphambili ihamba phambili.

Noma iyiphi imvamisa engaphansi kuka-80Hz kufanele ihanjiswe ku-subwoofer kanye nezipikha ze-bass. Ngemva kokusetha i-HPF ku-80Hz, lungisa i-LPF ukuze uthwebule amaza angaphansi kuka-80Hz. Ngakho-ke, ususa izikhala ekukhiqizeni umsindo - akukho imvamisa eshiywe ngaphandle kokunakwa.

Ukusetha amafrikhwensi aphakathi

Abantu abaningi bayangibuza ukuthi iyiphi i-frequency setting engcono kakhulu kumaza amaphakathi. Nakhu ke!

Isinyathelo 1: Lungisa i-midrange phakathi kuka-50Hz no-60Hz.

Kubaluleke kakhulu ukukhumbula ukuthi imvamisa emaphakathi yesipikha esikhulu semoto iphakathi kuka-50 Hz no-60 Hz. Kodwa-ke, amanye ama-audiophiles asebenzisa izilinganisi zokunambitheka okucashile. Ngakho-ke, thola i-midrange knob ku-amp bese usetha ku-50Hz noma ku-60Hz.

Isinyathelo sesi-2: Susa iziqongo ezibukhali namadiphu

Ukuze wenze lokhu, sebenzisa izilungiselelo ze-modulation noma zokulinganisa. Iziqongo ezibukhali namadiphu kudala imisindo enokhahlo, ngakho qiniseka ukuthi uyayiqeda ngezilungiselelo zakho ze-amp EQ. (1)

Izilungiselelo zesilinganisi ziphinde zehlukanise umsindo kumafrikhwensi aphansi, aphakathi nendawo naphezulu. Lokhu kukuvumela ukuthi uzenze ngendlela othanda ngayo; Nokho, abanye bancamela ukusebenzisa uhlelo lokusebenza ukushuna isikhulisi. Kodwa ngokuvamile udinga ukusetha ukuphakama kancane kunama-mids ukuze uthole umsindo ongcono kakhulu.

Ekugcineni, lapho usetha izilungiselelo ze-amplifier, qiniseka ukuthi zihambisana nezidingo zakho. Abantu bathanda ukungezwani emsindweni, futhi okuzwakala kukuhle kuwe kungase kube umsindo komunye umuntu. Akukho msindo omubi noma omuhle noma izilungiselelo ze-amp; Iphuzu liwukuqeda ukuhlanekezela.

Imigomo eyisisekelo nezilungiselelo ze-amplifier

Kuyadingeka ukuqonda imigomo eyisisekelo kanye nendlela yokusetha i-amplifier yemoto ngaphambi kokulungisa ama-mids kanye nokuphakama. Izinto eziguquguqukayo ezinjengomculo odlalwayo, isipikha, noma yonke isistimu ithinta ukushuna kwefrikhwensi emaphakathi nephezulu.

Ngaphezu kwalokho, kunezinkinobho ezimbalwa noma izilungiselelo ngemuva kwe-amplifier ezidinga ulwazi oluhle lwe-amplifier. Uma kungenjalo, ungase udideke noma uhlanekezele ukulungiselelwa. Ngezansi ngizoxoxa ngemiqondo eyinhloko ngokuningiliziwe.

imvamisa

Imvamisa inombolo yama-oscillation ngomzuzwana, akalwa ngo-Hertz, Hz. [1 Hertz == 1 umjikelezo ngomzuzwana]

Kumafrikhwensi aphezulu, amasignali omsindo akhiqiza imisindo ephezulu. Ngakho-ke, imvamisa iyisici esiyinhloko samafrikhwensi amaphakathi naphezulu kumsindo noma emculweni.

I-Bass ihlotshaniswa ne-bass, futhi kufanele ube nezipikha ze-bass ukuze uzwe amaza aphansi. Uma kungenjalo, amaza omsakazo aphansi angalimaza ezinye izipikha.

Ngokuphambene, amafrikhwensi aphezulu akhiqizwa kabusha izinsimbi ezifana namasimbali nezinye izinto zokusebenza zamafrikhwensi aphezulu. Kodwa-ke, asikwazi ukuzwa wonke amafrikhwensi - ububanzi bemvamisa yendlebe bungu-20 Hz ukuya ku-20 kHz.

Amanye amayunithi amafrikhwensi kuma-amplifiers emoto

Abanye abakhiqizi babala imvamisa kuma-decibel (dB) we-LPF, HPF, super bass, njalonjalo.

Inzuzo (ukuzwela kokokufaka)

I-Gain ichaza ukuzwela kwe-amplifier. Ungavikela isistimu yakho ye-stereo ekuhlanekezweni komsindo ngokulungisa inzuzo ngokufanele. Ngakho-ke, ngokulungisa inzuzo, ufinyelela ivolumu engaphezulu noma encane ekufakweni kwe-amplifier. Ngakolunye uhlangothi, ivolumu ithinta kuphela ukuphuma kwesipika.

Izilungiselelo zokuzuza okuphezulu ziletha umsindo eduze nokuhlanekezela. Kulokhu, kufanele ulungise kahle izilungiselelo zenzuzo ukuze ususe ukuhlanekezela ekuphumeni kwesipika. Uzoqinisekisa ukuthi isipika siletha kuphela amandla anele ukuqeda ukuhlanekezela komsindo.

AmaCrossovers

Ama-Crossovers aqinisekisa ukuthi isignali efanele ifinyelela umshayeli wayo ofanele. Lesi isisetshenziswa se-elekthronikhi esakhelwe kumjikelezo womsindo wemoto ukuze kuhlukaniswe imvamisa yomsindo kumabanga ahlukene. Ibanga ngalinye lefrikhwensi lihanjiswa kusipika esifanelekile - ama-tweeter, ama-subwoofers nama-woofers. Ama-tweeters athola amaza aphezulu, kuyilapho ama-subwoofers nama-woofer athola amaza aphansi kakhulu.

Izihlungi ze-High Pass

Bakhawulela amafrikhwensi afaka izipikha kumafrikhwensi aphezulu kuphela - aze afike kumkhawulo othile. Ngokunjalo, amaza aphansi ayavinjwa. Ngakho-ke, izihlungi ze-high-pass ngeke zisebenze nama-tweeter noma izipikha ezincane ezingalimala lapho amasiginali we-low-frequency edlula esihlungini.

Izihlungi ze-Low Pass

Izihlungi zokudlula okuphansi ziphambene nezihlungi zokudlula okuphezulu. Zikuvumela ukuthi udlulise amaza aphansi (kufika kumkhawulo othile) kuma-subwoofers nama-woofers - izipikha ze-bass. Ngaphezu kwalokho, bahlunga umsindo kumasignali alalelwayo, bashiye amasignali ebhesi abushelelezi ngemuva.

Ukufingqa

Ukusetha i-amplifier yemoto yamafrikhwensi aphakathi nendawo naphezulu akunzima. Kodwa-ke, kufanele uqonde izingxenye eziyisisekelo noma izakhi zokushuna komsindo - imvamisa, ama-crossovers, zuza ukulawula, nezihlungi zokudlula. Ngomculo wakho owuthandayo nolwazi olulungile, ungafinyelela imiphumela yomsindo ebabazekayo kusistimu yakho ye-stereo. (2)
