Indlela ukusetha i-subwoofer emotweni? Ikhishiwe inqubo incazelo

Subwoofer - iphupho abanikazi abaningi imoto. Nale divayisi, ungakwazi ukujabulela amathoni ongenamkhawulo umculo futhi ubukele amehlo nomona abanye abashayeli. Kodwa ngemva ukuthengwa kanye ukufakwa kudivayisi akufanele uphumule, ngakho indlela ukufaka ngokufanelekile subwoofer emotweni - kungcono kuyigxathu. Lokho-ke kwakuzwakala kukuhle, udinga ukuphatha kahle ke.

Ngakho-ke, ngemva yokufuna idivayisi cishe bonke abashayeli uyazibuza "indlela ukusetha subwoofer emotweni." Impendulo ke, uzofunda sihloko lanamuhla.

Endaweni yokuqala ngemva kokumiswa leli thuluzi, udinga ukusetha kabusha wonke amasethingi we kuyunithi. Bese ukhethe isikhundla lemifanekiso LPF amplifier wesiteshi adalule imvamisa oyifunayo (cishe 50-70 Hz). Ngemva kwalokho, kubalulekile ukuba bahumushe isihlungi ngaphambili isiteshi ukuze HPF. Mshini ngokwayo isendaweni amplifier. imvamisa wesiteshi kumele kungabi ngaphansi kuka-70 futhi engekho ngaphezulu kuka-90 Hertz.

Uma usebenzisa division yokwenziwa, kulesigaba umbuzo "indlela ukusetha subwoofer e umshini" ngawe kuqedile. Nokho, uma usebenzisa Per-isiteshi okhulisa, ngaphambi ukwenze lomnyenti, kusukela ngaphezu amplifier, kubalulekile ukuba ulungise Dynamics ngokwehlukile. Kulokhu siqinisa isiteshi isihlungi HPF ukwenzela ukubeka kuhle nokuhlela ulungiselele it ukuvama 2500 Hertz.

Kufanele ke ulungise nozwela isikhulumi. Ukuze wenze lokhu, thina kabusha amplifier imvamisa kuqanda, futhi umthamo lenziwe laba likhulu. Khona-ke vula isilawuli ukuzwela phezulu. Uma, ngemva kwalezi izilungiselelo uke waphawula yini ukuthi umsindo livela ukuhlanekezela, ukunciphisa ukubaluleka control.

Ngemva kwakho konke lokhu, thina hlola izinga lomsebenzi. Kahle kahle, umsindo kufanele isuke subwoofer ngaphandle ukuhlanekezela nokugxambukela. Kodwa ngisho noma umculo muhle, umbuzo uwukuthi "indlela ukusetha subwoofer e umshini" akakabi sikhathele siyingcuba. Nakani ekhethekile isikhathi uvale umsakazo. Uma ngalesi sikhathi uzwa umsindo ongaziwa ngesimo cod noma ukuchofoza, ukwazi ukuthi izikhulumi kufanele umsindo isilinganiso lophansi. Ukuxazulula lenkinga, hlola indawo izintambo lonke uhlelo. Khumbula ukuthi udinga hhayi kuphela ukwazi ukuthi ukulungisa kahle Dynamics, kodwa futhi ngokuphumelelayo ukufaka subwoofer ngezandla zakhe emotweni. Uma kudingeka, ukuhambisa izintambo ku kwenye indawo. Uma ezingemuva bass zenzeka, futhi akufanele, xhuma amplifier e antiphase. Ukuze wenze lokhu, kufanele uvule ama-degree angu-180 isigaba isilawuli, esemgwaqweni ku ebiyelwe subwoofer. Uma ungenayo lokhu, vele ushintshe phakathi wire uxhumano isikhulumi "+" futhi "-". Khona-ke kuyodingeka babe nomuzwa wokuthi lo umculo asizwakali emuva, futhi kusukela phakathi gumbi. Awukho umsindo futhi umsindo angahleliwe kusukela subwoofer ngeke okusezingeni eliphezulu.

Kuleli drive Dynamics angabhekwa igcwaliswe. Ngemva kokwenza lezi zinyathelo, ngeke usakwazi uzibuze "indlela ukusetha subwoofer emotweni."
