Kugadzira subwoofer mumotokari

Iyo subwoofer yakanaka yekuwedzera kune inonzwika system yemotokari. Asi zvakakosha kufunga kuti kutenga subwoofer inodhura haivimbisi ruzha rwemhando yepamusoro, nekuti chishandiso ichi chinoda kunyatsogadziriswa. Kuti ubatanidze uye ugadzire subwoofer zvakanaka, haufaniri kungova nekunzwa kwakanaka chete, asiwo ruzivo rwakadzika rwemotokari audio theory.

Zvechokwadi, usati wamisa subwoofer mumotokari, zvakanakisisa kutsvaga rubatsiro kubva kune nyanzvi, uye kune avo vanofambisa motokari vanoda kuzviita ivo pachavo, chinyorwa ichi chichabatsira.

Ndekupi kwekutanga kugadzira subwoofer?

Subwoofer tuning inotanga kubva panguva iyo bhokisi rinogadzirwa. Nekuchinja maitiro ebhokisi (vhoriyamu, kureba kwechiteshi), unogona kuzadzisa manzwi akasiyana. Panguva imwecheteyo, iwe unofanirwa kuziva pachine nguva kuti maodhiyo mafaira achanyanya kuridzwa mumotokari, uye kuti ndeipi amplifier ichabatanidzwa kune odhiyo system. Kana iyo subwoofer yatopihwa mune yemugadziri, ipapo kuchinjika kwekugadzika kuri, hongu, kushoma, kunyangwe neruzivo rwunodiwa zvinogoneka kuwana yaunoda ruzha mhando.

Chimwe chezvinhu zvakakosha zvinokanganisa kunaka kwezwi ndeye amplifier, tinokupa zano kuti uverenge chinyorwa "Maitiro ekusarudza amplifier".

LPF (lowpassfilter) kuseta kuseta

Kutanga iwe unofanirwa kuseta yakaderera-pass sefa (LPF). Yese subwoofer nhasi ine yakavakirwa-mukati LPF sefa. Iyo sefa inobvumidza iwe kuti usarudze chikumbaridzo painotangira kuvharira ma frequency epamusoro, ichibvumira iyo subwoofer chiratidzo kusanganisa zvakasikwa nevamwe vatauri.

Kuisa sefa, sekumisikidza inoshanda subwoofer, ine yakawanda yekuedza - hapana chakanangana "formula" chaiyo.

Iyo subwoofer yakagadzirirwa kubereka yakaderera frequencies, haigone kuimba, iri ibasa revatauri. Nekuda kweLPF yakaderera frequency sefa, tinogona kuita iyo subwoofer kutamba bass ikozvino. Iwe unofanirwa kuve nechokwadi chekuti kukosha kwesefa hakuna kukwirisa zvakanyanya uye iyo subwoofer haina kupindirana newoofers yeako mataurirwo akazara. Izvi zvinogona kukonzera kunyanya-kusimbisa pane imwe frequency renji (taura, yakatenderedza 120 Hz) uye ine fuzzy speaker system. Kune rimwe divi, kana iwe ukaisa sefa yakaderera zvakanyanya, panogona kunge paine misiyano yakawandisa pakati peiyo subwoofer siginecha uye mutauri chiratidzo.

Iyo subwoofer range inowanzoita 60 kusvika 120. Edza kuseta LPF sefa pa80 Hz kutanga, wozoedza ruzha. Kana iwe usingazvifarire, gadzirisa switch kusvika vatauri vanzwika sezvaunoda.

Paredhiyo pachayo, sefa inofanira kudzimwa.

Subsonic tuning

Tevere, iwe unofanirwa kumisa iyo infrasonic sefa, iyo inonzi "subsonic". Iyo subsonic inovhara iyo yekupedzisira-yakaderera ma frequency anowanzoitika mune dzimwe nziyo. Iwe haugone kunzwa mafambiro aya nekuti aripo pazasi pemukumbaridzo wekunzwa kwevanhu.

Asi kana dzisina kuchekwa, iyo subwoofer inoshandisa simba rekuwedzera kudziridza. Nekuvhara infra-low frequencies, mudziyo unozokwanisa kunyatso kubereka chaizvo iwo ma frequency ari mukati meinonzwika renji. Uyezve, mune iyi kesi, kukundikana kweiyo subwoofer coil nekuda kwekukurumidza kufamba kweiyo diffuser kunobviswa.

Chii chinonzi Bassboost?

Mazhinji amplifiers anosanganisirawo Bassboost switch iyo inogona kuwedzera simba reiyo subwoofer nekuiisa kune yakatarwa frequency. Vamwe vatyairi vanoshandisa switch kuti inzwi rive "rakapfuma", kunyangwe richiwanzo shandiswa kugovera zvakaenzana mabhasi. Kana iwe ukaisa shanduko kune iyo yakanyanya kukosha, ipapo subwoofer inogona kupisa kunze, zvisinei, kudzima Bassboost zvachose hakukodzeri zvakare, nekuti mune iyi nyaya, mabhasi anogona kusanzwika zvachose.

Kugadzirisa Sensitivity Yekupinza (GAIN)

Vamwe vatyairi havanzwisise nzira yekuseta nemazvo senitivity yekupinza. Input sensitivity inoratidza kuti ingani siginecha inogona kuiswa kune yekuisa kuitira kuti uwane yakatemerwa inobuda simba. Inofanirwa kugadziridzwa kuti ive yakajairika yekupinza chiratidzo voltage.

Izvo zvakanyanya kukosha kuseta yekupinza senitivity nenzira kwayo, sezvo izvi zvichabatsira kudzivirira kukanganiswa kwechiratidzo, hurombo husina kunaka hwekunzwika, kana kukuvadzwa kwevatauri.

Kugadzirisa "GAIN", unoda

1. digital voltmeter inogona kuyera AC voltage values;
2. bvunzo CD kana faira rine 0 dB sine wave (yakanyanya kukosha kuti usashandise yakadzikira bvunzo chiratidzo);
3. mirairo ye subwoofer, iyo inoratidza inobvumirwa kubuda voltage.

Kutanga iwe unoda kubvisa waya dzekutaura kubva kune subwoofer. Tevere, iwe unofanirwa kuve nechokwadi chekuti bass, equalizers uye mamwe ma parameter akadzimwa pane iyo musoro unit kuitira kuti uwane ruzha rwakajeka. Muchiitiko ichi, iyo yekupinda senitivity level inofanira kunge yakaderera sezvinobvira.

Ita shuwa kuti digital voltmeter inokwanisa kuverenga AC voltage uye kuibatanidza kune masipika maspeaker pazvitauriri zvako (unogona kuichengetedza nescrewdriver). Mushure meizvozvo, iwe uchafanirwa kushandura senitivity "twist" kusvikira voltmeter ichiratidza kukosha kwevoltage inodiwa, iyo yakaratidzwa mune zvakatemwa.

Tevere, iyo yakanyorwa faira redhiyo ine sinusoid inofanirwa kupihwa kune subwoofer nguva nenguva nekushandura vhoriyamu yeaudio system kusvika kupindira kwaitika. Muchiitiko chekuvhiringidza, ivhu rinofanira kudzorerwa kune kukosha kwayo kwekare. Izvo zvakafanana zvinoenda pakugadzirisa sensitivity. An oscilloscope inogona kushandiswa kuwana iyo yakanyanya data data.

Acoustic phase

Mazhinji subwoofers ane switch kumusana inonzi "Phase" inogona kuiswa ku 0 kana 180 madhigirii. Kubva pakuona kwemagetsi, ichi ndicho chinhu chechipiri chiri nyore kuita mushure mekudzima/kudzima.

Kana iwe ukaseta chinja chemagetsi kune rimwe divi, ipapo makondakita maviri anotakura chiratidzo kubva painobuda kuenda kune mamwe emagetsi mune imwe nzira. Zvakakwana kuti flip chinja uye vaviri conductor kuchinja nzvimbo. Izvi zvinoreva kuti chimiro cheruzha chichadzoserwa kumashure (ndizvo zvinorehwa nemainjiniya pavanotaura nezve kudzosera chikamu, kana kuchichinja 180 madhigirii).

Asi muteereri wenguva dzose anowanei semugumisiro wechikamu chekugadzirisa?

Icho chokwadi ndechekuti nerubatsiro rwemanipulations neiyo phase switch, unogona kuwana yakanyanya kuona yepakati nepamusoro bass uchiteerera. Izvo ndezvekutenda kune phase shifter kuti iwe unogona kuwana ese mabass awakabhadharira.

Uye zvakare, iyo chikamu chinogadziriswa chemonoblock chinobatsira kuwana chaizvo ruzha rwepamberi. Zvinowanzoitika kuti inzwi rinoparadzirwa zvisina kuenzana muimba yose (mimhanzi inonzwika chete kubva pahunde).

Kunonoka

Subwoofers inowanzoita kunonoka kudiki, uye inoenderana zvakananga nehukuru hwechinhambwe. Semuenzaniso, vatauri vanobva kuAmerican mugadziri Audissey vakaisa nemaune chinhambwe kuti vadzivise kunonoka uku.

Izvo zvakakosha kucherechedza kuti manyorero ekugadzirisa amplifier ye subwoofer inogoneka chete kana paine yekunze processor kana yakabatanidzwa processor. Chiratidzo chekuti subwoofer iri kukonzeresa kunonoka ndeye kunonoka bass, iyo dzimwe nguva inoparadza ruzha. Chinangwa chekunonoka kuseta ndeyekuzadzisa panguva imwe chete yekutamba kwe subwoofer uye vatauri vepamberi (inzwi harifanirwe kubvumidzwa kurembera kunyangwe kwemasekonzi akati wandei).

Nei zvakakosha kuti dock subwoofers uye midbass nenzira kwayo?

Kana iyo subwoofer isina kuvharwa neiyo midbass, ipapo ruzha ruchava rwehurombo uye yakaderera. Izvi zvinonyanya kuoneka pane yakaderera frequencies, kana imwe mhando yezvisina maturo inowanikwa panzvimbo pechene bass. Dzimwe nguva sarudzo dzakaipa dzakadaro dzinogoneka, kana ruzha runobva kune subwoofer ruchiwanzo kurira rwakazvimiririra.

Muchokwadi, izvi zvinoshanda kumarudzi ese emimhanzi, uye kwete kungotaura, classical kana rock mimhanzi, uko kuridzwa kwe "kurarama" zviridzwa zvemimhanzi kunoonekwa.

Semuenzaniso, mumakwara ari emhando yeEDM, iyo inonyanya kufarirwa pakati pevechidiki, mabhesi akajeka anowanikwa padhuze nepakati. Kana ukaamisa zvisizvo, ipapo low-frequency loud bass hazvizonyanya kushamisira, uye zvakanyanya kutadza kunzwika.

Sezvo zvichidikanwa kurongedza amplifier kune imwechete frequency, zvinokurudzirwa kushandisa audio spectrum analyzer kuti uwane iyo yakanyanya data data.

Nzira yekunzwisisa sei kuti wakamisa subwoofer zvakarurama?

Kana iyo subwoofer yakabatana zvakanaka, saka vanhu vari mumotokari havagoni kuinzwa, nokuti haifaniri kupindira nechiratidzo chikuru.

Kana iwe ukateerera mimhanzi nezwi rakaderera, zvingaita sekuti hapana mabhesi akakwana. Kushaikwa kwebass pamavhoriyamu akaderera chiratidzo chechokwadi chekuti subwoofer yakabatana nemazvo.

Ehezve, hapafanirwe kuve neruzha, kukanganisa kana kunonoka muchiratidzo cheodhiyo, uye hazvina mhosva kuti rudzii rwekugadzira runoshandiswa.

Iperesenti yemabass mune yega yega track inofanira kunge yakasiyana, kureva kuti, kutamba kunofanirwa kunyatsoenderana neyekutanga track yakanyorwa nemugadziri.
