Thaum muab tso ua ke lub tsev ua yeeb yam zoo hauv tsev, lub subwoofer yog qhov tsim nyog yuav khoom. Lub subwoofer yog tus hais lus tshwj xeeb uas tau tsim los tsim cov zaus qis heev.
Rau suab paj nruag, txhais tau hais tias acoustic lossis hluav taws xob ntses bass thaj tsam, thiab ntau cov yeeb yaj kiab uas txhais tau hais tias lub tsheb ciav hlau khiav hauv txoj kev tsheb ciav hlau, hluav taws kub nyhiab thiab tawg, thiab qhov kev sim loj: qhov sib sib zog nqus ntawm av qeeg.
Txawm li cas los xij, ua ntej koj tuaj yeem txaus siab rau txhua yam, koj yuav tsum ua ke nrog lub subwoofer nrog rau qhov seem ntawm koj lub cev, thiab koj txuas lub subwoofer li cas rau tag nrho koj lub tsev ua yeeb yam teeb tsa nyob ntawm seb nws puas yog Powered los yog Passive.
Passive Subwoofers
Passive subwoofers yog hu ua "passive" vim tias lawv yuav tsum tau siv lub tshuab hluav taws xob sab nraud, zoo ib yam li cov neeg hais lus nrov.
Qhov kev txiav txim siab tseem ceeb yog vim tias cov subwoofer xav tau ntau lub zog los tsim cov suab nrov tsawg, lub suab nrov lossis lub receiver yuav tsum muaj peev xwm tsim tau lub zog txaus los txhawb nqa cov txiaj ntsig bass uas tau tsim los ntawm subwoofer yam tsis tau tso lub receiver los yog amplifier lub hwj chim mov.. Lub hwj chim ntau npaum li cas nyob ntawm qhov yuav tsum tau ua ntawm tus hais lus subwoofer thiab qhov loj ntawm chav tsev (thiab ntau npaum li cas ntses bass thaj tsam koj tuaj yeem ua rau plab, lossis ntau npaum li cas koj xav cuam tshuam cov neeg nyob ze!).
Ib yam li lwm tus hais lus nrov hauv kev teeb tsa hauv tsev ua yeeb yam, koj txuas tus neeg hais lus xov tooj ntawm lub tshuab hluav taws xob mus rau qhov tsis muaj zog subwoofer. Qhov zoo tshaj plaws, koj yuav tsum xub txuas lub subwoofer kab tawm ntawm lub tsev ua yeeb yam txais lossis AV preamp processor, mus rau cov kab nkag ntawm lub tshuab hluav taws xob sab nraud.
Koj mam li txuas tus hais lus tawm ntawm lub tshuab hluav taws xob subwoofer mus rau tus hais lus terminals ntawm passive subwoofer.
Passive subwoofers feem ntau yog siv rau hauv kev teeb tsa kev cai qhov twg lub subwoofer yuav raug ntsia rau hauv ib phab ntsa, txawm hais tias muaj qee cov khoom siv hluav taws xob zoo li lub subwoofer uas tseem ua tau. Tsis tas li ntawd, qee qhov pheej yig hauv tsev-theatre-hauv-ib-lub thawv tshuab suav nrog lub tshuab hluav taws xob tsis zoo, xws li Onkyo HT-S7800.
Powered Subwoofers
Yuav daws qhov teeb meem ntawm lub hwj chim tsis txaus los ntawm ib qho chaw txais lossis lub tshuab hluav taws xob, Powered Subwoofers (tseem hu ua Active Subwoofers) tau siv. Hom subwoofer no yog tus kheej muaj. Nws nta tus hais lus / amplifier configuration nyob rau hauv uas cov yam ntxwv ntawm lub amplifier thiab subwoofer hais lus yog optimally matched thiab encased nyob rau hauv tib lub enclosure.
Raws li ib qho txiaj ntsig, tag nrho cov kev xav tau ntawm lub tshuab hluav taws xob subwoofer yog ib qho kev sib txuas ntawm ib qho kev sib txuas ntawm lub tsev ua yeeb yam los yog ib puag ncig lub suab preamp / processor kab tawm (tseem hu ua subwoofer preamp tso zis lossis LFE tso zis).
Lub cable ces mus ntawm sub preamp / LFE cov zis tawm mus rau cov khoom siv sib txuas ntawm lub tshuab hluav taws xob subwoofer.
Qhov kev npaj no siv ntau lub zog thauj khoom kom deb ntawm lub receiver thiab tso cai rau lub receiver tus kheej amplifiers kom lub zog nruab nrab thiab tweeter hais lus yooj yim dua.
Qhov twg Zoo dua - Passive lossis Powered?
Txawm hais tias lub subwoofer passive lossis powered tsis yog qhov kev txiav txim siab ntawm qhov zoo ntawm lub subwoofer. Txawm li cas los xij, Powered subwoofers yog nyob deb ntawm feem ntau siv raws li lawv muaj lawv tus kheej built-in amplifiers thiab tsis nyob ntawm ib qho kev txwv amplifier ntawm lwm lub receiver lossis amplifier. Qhov no ua rau lawv yooj yim heev rau siv nrog tsev ua yeeb yam txais tos. Txhua lub tsev ua yeeb yam hauv tsev tuaj yeem nruab nrog ib lossis ob lub subwoofer pre-amp kab tawm uas tau tsim tshwj xeeb los txuas rau lub zog subwoofer.
Ntawm qhov tod tes, lub tshuab hluav taws xob sab nraud yuav tsum tau khiav lub passive subwoofer tej zaum yuav kim dua li passive subwoofer koj muaj.
Feem ntau, nws raug nqi ntau dua los yuav lub tshuab hluav taws xob subwoofer los ntawm Passive Subwoofer. Yog tias koj tseem xaiv qhov kev xaiv passive, lub subwoofer ua ntej tawm los ntawm lub tsev ua yeeb yam hauv tsev yuav tsum txuas mus rau sab nraud subwoofer amplifier txoj kab-hauv kev sib txuas, nrog rau sab nraud amplifier lub subwoofer hais lus txuas mus rau passive subwoofer.
Tsuas yog lwm txoj kev sib txuas yog muaj rau lub subwoofer passive yog tias yog tias lub subwoofer passive muaj nyob rau hauv thiab tawm tus qauv hais lus sib txuas, koj tuaj yeem txuas cov lus sib txuas sab laug thiab sab xis ntawm lub receiver lossis amplifier rau passive subwoofer. thiab tom qab ntawd txuas rau sab laug thiab sab xis cov lus tso tawm kev sib txuas ntawm passive subwoofer rau koj lub ntsiab lus sab laug thiab sab xis.
Nyob rau hauv hom kev teeb tsa no, lub subwoofer yuav "tshem tawm" cov zaus qis uas siv qhov kev sib tshuam sab hauv, xa cov nruab nrab thiab siab zaus mus rau cov neeg hais lus ntxiv txuas nrog lub subwoofer tus hais lus tawm. Qhov no tshem tawm qhov xav tau rau ib qho ntxiv amplifier rau lub passive subwoofer tab sis tej zaum yuav ua rau muaj kev nyuaj siab ntau dua rau koj lub receiver lossis amplifier vim qhov xav tau rau cov suab nrov tsawg zaus.
Kev zam rau txoj cai sib txuas ntawm Subwoofer
Ntau lub tshuab hluav taws xob subwoofer muaj ob qho tib si kab lus thiab cov lus sib txuas. Qhov no ua rau nws lees txais cov teeb liab los ntawm ib qho amplifier tus hais lus sib txuas lossis lub suab nrov / lub tsev ua yeeb yam receiver subwoofer preamp tso zis kev sib txuas. Txawm li cas los xij, nyob rau hauv ob qho tib si, cov teeb liab tuaj dhau los ntawm lub zog hluav taws xob hauv lub amps, nqa cov khoom tawm ntawm lub receiver.
Qhov no txhais tau tias yog tias koj muaj lub tsev ua yeeb yam qub lossis lub suab nrov uas tsis muaj kev sib txuas ntawm subwoofer preamp tso zis, koj tseem tuaj yeem siv lub tshuab hluav taws xob subwoofer nrog ob tus qauv hais lus sib txuas thiab cov kab nkag.
Txoj Kev Sib Txuas Wireless
Lwm txoj kev sib txuas ntawm subwoofer uas tau txais kev nrov dua (tsuas yog ua haujlwm nrog lub tshuab hluav taws xob subwoofer) yog kev sib txuas wireless ntawm lub subwoofer thiab lub tsev ua yeeb yam txais lossis amplifier. Qhov no tuaj yeem siv tau ob txoj hauv kev.
- Thaum lub subwoofer los nrog lub wireless receiver built-in thiab tseem muab lub wireless transmitter sab nraud uas ntsaws rau hauv subwoofer kab tawm ntawm lub tsev ua yeeb yam receiver lossis amplifier.
- Koj tuaj yeem yuav cov khoom siv wireless transmitter / receiver uas tuaj yeem txuas rau txhua lub tshuab hluav taws xob subwoofer uas muaj cov kab nkag thiab txhua lub tsev ua yeeb yam receiver, AV processor, lossis amplifier uas muaj subwoofer lossis LFE kab tawm (saib piv txwv kev sib txuas rau ib pob khoom hauv qab).
Txoj kab hauv qab
Ua ntej yuav ib lub subwoofer siv nrog koj lub tsev ua yeeb yam, xyuas seb koj lub tsev ua yeeb yam, AV, los yog ib puag ncig lub suab receiver muaj lub subwoofer preamp tso zis (feem ntau sau npe Sub Pre-Out, Sub Out, los yog LFE Out). Yog tias muaj, ces koj yuav tsum siv lub tshuab hluav taws xob subwoofer.
Tsis tas li, yog tias koj nyuam qhuav yuav lub tsev ua yeeb yaj kiab tshiab hauv tsev, thiab muaj lub subwoofer sab laug uas tau los nrog lub tsev ua yeeb yam-hauv-ib-lub thawv, kos saib seb lub subwoofer puas yog qhov tsis zoo. subwoofer. Qhov muab yog tias nws tsis muaj cov kab ntawv subwoofer thiab tsuas yog muaj kev sib txuas lus. Yog tias muaj, koj yuav tsum tau yuav ib qho amplifier ntxiv rau lub zog subwoofer.
