Momwe Mungasinthire Amplifier Yagalimoto ya Mids ndi Highs (Guide with Photos)
Zamkatimu
M'nkhaniyi, ndikuphunzitsani momwe mungakhazikitsire amplifier yamagalimoto apakati komanso apamwamba mumphindi zochepa.
Kusokoneza kwa audio kumachitika ngati kuchuluka kwa kuwongolera kumayikidwa kwambiri. Monga wokonda kwambiri stereo yemwe amagwira ntchito mu shopu ya stereo yamagalimoto, ndili ndi luso lopanga zokulitsa mawu kuti ndimveke bwino. Mutha kuthetsa kupotoza mu stereo yanu mwa kukonza bwino ma mids ndi ma trebles ndi ma treble ndi ma bass. Mudzapewanso kupotoza kwamawu komwe kumawononga okamba ndi zida zina zamawu, ndipo simungawononge kapena kuwononga ndalama zina kuti mukonzere makina anu omvera.
Mwachangu Mwachidule: Njira zotsatirazi zidzasinthiratu amplifier yamagalimoto anu amkatikati ndi okwera:
- Kusewera nyimbo zomwe mumakonda kapena nyimbo
- Pezani chowongolera kuseri kwa amplifier ndikutembenuzira chapakati.
- Sinthani voliyumu kukhala pafupifupi 75 peresenti
- Bweretsani kuwongolera kopindulitsa ndikuwonjezera pang'onopang'ono pafupipafupi mpaka zizindikiro zoyamba zosokoneza ziwonekere.
- Mutha kugwiritsanso ntchito ma multimeter kuti musinthe kuwongolera kopindulitsa.
- Yendetsani kusintha kwa HPF pa amplifier ndikuyika HPF ku 80Hz kuti muyike ma frequency apamwamba.
- Sinthani ma frequency apakati pakati pa 59 Hz ndi 60 Hz kuti mukhale ndi mawu abwino kwambiri.
- Chotsani nsonga zolimba ndikuviika ndi amp's EQ control.
Pansipa ndipita mozama mu izi.
Kusintha ma frequency apakati ndi apamwamba
Kuyika kwa amplifier kumadaliranso mtundu wa amplifier mu stereo yagalimoto yanu. Oyamba ayenera kuwonetsetsa kuti palibe ma frequency otsika pafupi ndi okamba awo.
Komanso, mukufunikira Kupeza koyenera kuti mupeze ipf ndi hpf zolondola zama mods ndi max. Pewani kupotoza, ngakhale kungathe kuchepetsedwa kapena kuthetsedwa mosavuta. Kusokoneza kungayambitse kuwonongeka kosaneneka kwa okamba ndi makutu anu. Kusokonekera kumachitika mukayika chiwongolero chokwera kwambiri ndiyeno amplifier imatumiza ma siginecha odulidwa kwa okamba. Nyimbo zaphokoso zimapangitsa kuti zinthu ziipireipire chifukwa okamba nkhani amakhala atadzaza kale.
Momwe mungakhazikitsire ulamuliro wopeza
Kuti muchite izi:
mwatsatane 1. Sewani nyimbo yomwe mukuidziwa chifukwa mukudziwa momwe ikumvekera.
Pa amp, pezani mfundo ya Gain ndikutembenuzira pafupifupi theka la njira - osayiyika kukhala mphamvu zonse.
mwatsatane 2. Sinthani voliyumu mpaka 75 peresenti - kusokoneza kumayambira pama voliyumu okwera kwambiri, chifukwa chake musakhazikitse kuchuluka kwake.
mwatsatane 3. Mvetserani nyimbo zikuyimba ndikuwona ngati zili zabwino.
mwatsatane 4. Bwererani ku chiwongolero chopindula kumbuyo kwa amplifier ndikusintha (zovuta) mpaka kusokoneza kuyambika. Siyani kukweza voliyumu mukangowona kuti zasokonekera.
Kapenanso, mutha kugwiritsa ntchito ma multimeter kuti musinthe kuwongolera kopindulitsa.
Kukhazikitsa ma maximums
Ngati mukufuna ma frequency okwera pama speaker anu, ndiye kuti fyuluta ya HPF high pass ndi yomwe mukufuna. HPF imaletsa ma siginecha otsika omwe samapangidwanso bwino ndi olankhula ndi ma tweeters. Zizindikiro zochepa zimatha kuwotcha okamba anu, kotero HPF imathandiza kupewa izi.
Njira zotsatirazi zikuthandizani kuyitanira treble:
Khwerero 1: Yendetsani chosinthira cha Hpf pa amplifier, kapena gwiritsani ntchito screwdriver kuti musinthe ngati palibe chosinthira.
Kuti mutsegule zoikamo, sinthani chosinthira chokwera kwambiri pa amplifier yanu. Ma amps ambiri amakhala ndi chosinthira, koma zimatengera OEM.
Gawo 2: Khazikitsani Zosefera Zapamwamba kukhala 80Hz
Ma HPF amazindikira momwe amagwirira ntchito bwino kuyambira 80Hz mpaka 200Hz, koma akale ndi abwino kwambiri.
Mafupipafupi aliwonse omwe ali pansi pa 80Hz akuyenera kutumizidwa ku subwoofer ndi ma bass speaker. Mukakhazikitsa HPF ku 80Hz, sinthani LPF kuti igwire ma frequency pansi pa 80Hz. Chifukwa chake, mumachotsa mipata pakutulutsa mawu - palibe ma frequency omwe amasiyidwa popanda chidwi.
Kukhazikitsa ma frequency apakati
Anthu ambiri amandifunsa kuti ma frequency amtundu wanji ndi abwino kwa ma frequency apakati. Nazi!
Gawo 1: Sinthani pakati pa 50Hz ndi 60Hz.
Ndikofunikira kwambiri kukumbukira kuti ma frequency amtundu wa choyankhulira chachikulu chagalimoto ndi pakati pa 50 Hz ndi 60 Hz. Komabe, ma audiophiles ena amagwiritsa ntchito zofananira kuti amve bwino kwambiri. Chifukwa chake, pezani mfundo yapakati pa amp ndikuyiyika ku 50Hz kapena 60Hz.
Gawo 2: Chotsani nsonga zakuthwa ndi ma dips
Kuti muchite izi, gwiritsani ntchito ma modulation kapena ma equalizer. Kukwera nsonga zakuthwa ndi kuviika kumapanga mawu ankhanza, choncho onetsetsani kuti mwawachotsa ndi ma EQ anu amp. (1)
Zokonda za Equalizer zimalekanitsanso mawuwo kukhala ma frequency otsika, apakati komanso apamwamba. Izi zimakupatsani mwayi wosintha momwe mungakonde; Komabe, ena amakonda kugwiritsa ntchito pulogalamu kuti asinthe amplifier. Koma kawirikawiri muyenera kuyika zokwera pang'ono kuposa zapakati kuti mumveke bwino kwambiri.
Pomaliza, pokhazikitsa zoikamo amplifier, onetsetsani kuti zikugwirizana ndi zosowa zanu. Anthu amakonda mawu osiyanasiyana, ndipo zomwe zimamveka bwino kwa inu zitha kukhala zaphokoso kwa munthu wina. Palibe zoikamo zoipa kapena zabwino kapena amplifier; Mfundo yake ndi kuthetsa kupotoza.
Mawu oyambira ndi zoikamo amplifier
Ndikofunikira kumvetsetsa mawu ofunikira komanso momwe mungakhazikitsire amplifier yamagalimoto musanayambe kusintha pakati ndi ma highs. Zosintha monga nyimbo zomwe zikuimbidwa, choyankhulira, kapena makina onse zimakhudza kusintha kwapakati komanso pafupipafupi.
Kuphatikiza apo, pali mabatani angapo kapena zosintha kumbuyo kwa amplifier zomwe zimafuna kudziwa bwino za amplifier. Kupanda kutero, mutha kusokonezeka kapena kusokoneza makonzedwe. Pansipa ndikambirana mfundo zazikulu mwatsatanetsatane.
pafupipafupi
Frequency ndi kuchuluka kwa ma oscillation pa sekondi iliyonse, kuyezedwa mu Hertz, Hz. [1 Hertz == kuzungulira 1 pamphindikati]
Pamaulendo apamwamba, ma siginecha amawu amatulutsa mawu okweza kwambiri. Chifukwa chake, ma frequency ndi chinthu chofunikira kwambiri pamayendedwe apakatikati komanso apamwamba pamawu kapena nyimbo.
Bass imalumikizidwa ndi mabass, ndipo muyenera kukhala ndi oyankhula kuti mumve ma frequency otsika. Kupanda kutero, mafunde otsika a wailesi amatha kuwononga olankhula ena.
Mosiyana ndi izi, ma frequency apamwamba amapangidwanso ndi zida monga zinganga ndi zida zina zapamwamba kwambiri. Komabe, sitingamve ma frequency onse - ma frequency a khutu ndi 20 Hz mpaka 20 kHz.
Magawo ena pafupipafupi pama amplifiers agalimoto
Opanga ena amalemba pafupipafupi ma decibel (dB) a LPF, HPF, super bass, ndi zina zotero.
Kupeza (kutengera chidwi)
Gain amafotokoza kukhudzika kwa amplifier. Mutha kuteteza makina anu a stereo kuti asasokonezedwe ndi ma audio posintha phindu moyenera. Chifukwa chake, posintha phindu, mumakwaniritsa voliyumu yochulukirapo kapena yocheperako pakulowetsa kwa amplifier. Kumbali ina, kuchuluka kwa mawu kumangokhudza kutulutsa kwa speaker.
Zokonda zopindula kwambiri zimabweretsa phokoso pafupi ndi kusokoneza. Mwanjira iyi, muyenera kukonzanso zosintha kuti muchepetse kupotoza kwa speaker. Mudzawonetsetsa kuti wokamba nkhani amangopereka mphamvu zokwanira kuti athetse kusokoneza kwa mawu.
Otsutsa
Crossovers amaonetsetsa kuti chizindikiro cholondola chikufikira dalaivala wake woyenera. Ichi ndi chipangizo chamagetsi chomwe chimapangidwa mumayendedwe omvera agalimoto kuti alekanitse ma frequency amawu m'magawo osiyanasiyana. Ma frequency aliwonse amaperekedwa kwa olankhula oyenera - ma tweeters, subwoofers ndi woofers. Ma tweeter amalandira ma frequency apamwamba, pomwe ma subwoofers ndi woofer amalandila ma frequency otsika kwambiri.
Zosefera Zapamwamba
Amachepetsa ma frequency omwe amalowetsa okamba ku ma frequency apamwamba okha - mpaka malire ena. Chifukwa chake, ma frequency otsika amatsekedwa. Chifukwa chake, zosefera zapamwamba sizingagwire ntchito ndi ma tweeters kapena oyankhula ang'onoang'ono omwe amatha kuonongeka pamene zizindikiro zotsika zimadutsa mu fyuluta.
Zosefera za Low Pass
Zosefera zotsika ndizosiyana ndi zosefera zapamwamba. Amakulolani kuti mutumize maulendo otsika (mpaka malire ena) kwa ma subwoofers ndi woofers - oyankhula bass. Kuphatikiza apo, amasefa phokoso pamasinthidwe amawu, ndikusiya ma bass osalala kumbuyo.
Kufotokozera mwachidule
Kukhazikitsa amplifier yamagalimoto apakati ndi ma frequency apamwamba sikovuta. Komabe, muyenera kumvetsetsa zigawo zikuluzikulu kapena zinthu zosinthira mawu - pafupipafupi, ma crossover, kuwongolera, ndikudutsa zosefera. Ndi nyimbo zomwe mumakonda komanso chidziwitso choyenera, mutha kukwaniritsa mawu opatsa chidwi pamakina anu a stereo. (2)
Onani zina mwazolemba zathu pansipa.
- Momwe mungalumikizire okamba zigawo
- Kodi waya wapinki pa wailesi ndi chiyani?
- Ndi ma watt angati omwe amatha kupanga chogwirira cha waya cha 16 gauge
