Xaiv lub amplifier rau koj lub kaw lus

Thaum xub thawj siab ib muag, tej zaum nws yuav zoo li hais tias cov txheej txheem ntawm kev xaiv ib tug amplifier nyob rau hauv lub tsheb rau hais lus los yog ib tug subwoofer tsis yog li ntawd yooj yim. Tab sis muaj cov lus qhia luv luv "Yuav ua li cas xaiv lub amplifier" yuav tsis ua teeb meem. Lub hom phiaj ntawm lub amplifier rau lub kaw lus suab yog coj lub teeb liab qis thiab hloov mus rau lub teeb liab siab kom tsav tus neeg hais lus.

Tej zaum lawv yuav txawv ntawm cov xov tooj ntawm amplification channel, lub zog thiab tus nqi. Ob thiab plaub-channel amplifiers yog nyob rau hauv qhov xav tau loj tshaj plaws ntawm cov neeg tsav tsheb. Thiab tam sim no cia peb teb cov lus nug ntawm yuav ua li cas xaiv lub amplifier hauv lub tsheb kom ntxaws ntxiv.

Tsheb Amplifier Chav Kawm

Ua ntej tshaj plaws, kuv xav tham txog cov chav kawm amplifier, thaum lub sijhawm muaj ntau tus ntawm lawv, tab sis peb yuav xav txog ob lub ntsiab uas muaj ntau heev hauv lub tsheb suab. Yog tias koj txaus siab rau cov ncauj lus no kom ntxaws ntxiv, thaum kawg ntawm tsab xov xwm muaj ib daim vis dis aus uas hais txog txhua chav kawm ntawm nws pib amplifiers uas tam sim no pom.

• Class AB amplifier. Cov amplifiers muaj lub suab zoo heev, nrog rau txoj kev sib txuas lawv muaj kev ntseeg siab thiab ruaj khov. Yog hais tias AB chav kawm amplifier muaj lub zog siab, ces nws muaj tag nrho qhov ntev, cov amplifiers muaj qhov ua haujlwm qis ntawm li 50-60%, piv txwv li yog 100 watts tau pub rau hauv lawv. lub zog, ces tam sim no ntawm 50-60 watts yuav ncav cuag cov neeg hais lus. Tus so ntawm lub zog tsuas yog hloov mus rau hauv tshav kub. Nws yog tsis yooj yim sua rau nruab chav kawm AB amplifiers nyob rau hauv qhov chaw kaw, txwv tsis pub, nyob rau hauv cov huab cua kub, nws muaj peev xwm mus rau hauv kev tiv thaiv.
• Class D amplifier (digital amplifier). Yeej, chav kawm D muaj nyob rau hauv monoblocks (ib leeg-channel amplifiers), tab sis kuj muaj plaub thiab ob-channel sib txuas rau acoustics. Qhov no amplifier muaj ntau yam zoo. Piv nrog rau chav kawm AB, nrog tib lub zog, nws muaj qhov loj me me. Kev ua haujlwm ntawm cov amplifiers tuaj yeem ncav cuag 90%, nws xyaum tsis ua kom sov. D chav kawm tuaj yeem ua haujlwm ruaj khov hauv qis ohmic load. Txhua yam yuav zoo, tab sis lub suab zoo ntawm cov amplifiers yog qis dua rau chav kawm AB.

Peb xaus nqe lus no nrog kev xaus. Yog tias koj tab tom nrhiav suab zoo (SQ), ces nws yuav yog qhov tseeb dua los siv chav kawm AB amplifiers. Yog tias koj xav tsim kom muaj lub suab nrov heev, nws yog qhov zoo dua los xaiv rau Class D amplifiers.

Tus naj npawb ntawm amplifier channel.

Cov ntsiab lus tseem ceeb tom ntej no yog tus naj npawb ntawm amplifier channel, nws nyob ntawm seb koj tuaj yeem txuas rau nws. Txhua yam yooj yim ntawm no, tab sis cia peb saib ze dua:

         

• Ib leeg-channel amplifiers, lawv tseem hu ua monoblocks, lawv tau tsim los txuas cov subwoofers, feem ntau lawv muaj chav kawm D thiab muaj peev xwm ua haujlwm ntawm qhov tsis muaj zog. Cov chaw (filter) yog npaj rau lub subwoofer, piv txwv li yog tias koj txuas tus hais lus yooj yim rau lub monoblock, nws yuav rov tsim cov ntses bass thaj tsam tam sim no.

 

• Ob-channel amplifiers, raws li koj yuav twv, koj tuaj yeem txuas ob peb tus neeg hais lus rau nws. Tab sis kuj feem ntau ob-channel amplifiers tuaj yeem ua haujlwm hauv kev sib txuas. Qhov no yog thaum lub subwoofer txuas nrog ob lub channel. Cov amplifiers muaj universal (filter) teeb tsa, piv txwv li lawv muaj HPF hloov, hom no rov tsim cov zaus tam sim no, thiab thaum hloov mus rau LPF lim, lub amplifier yuav tso tawm tsawg zaus rau cov zis tam sim no (qhov teeb tsa no tsim nyog rau lub subwoofer) .
• Yog tias koj nkag siab tias ob-channel amplifier yog dab tsi, ces txhua yam yog yooj yim nrog plaub-channel, cov no yog ob-channel amplifiers, piv txwv li koj tuaj yeem txuas plaub tus neeg hais lus rau nws, lossis 2 tus neeg hais lus thiab ib lub subwoofer, muaj tsawg zaus ob lub subwoofer yog. txuas, tab sis peb tsis pom zoo ua qhov no. Lub amplifier yuav kub heev thiab yav tom ntej nws yuav siv tsis tau.
  
  Peb thiab tsib channel amplifiers yog qhov tsawg kawg nkaus. Txhua yam yooj yim ntawm no, koj tuaj yeem txuas ob tus neeg hais lus thiab lub subwoofer rau peb-channel amplifier, 4 tus neeg hais lus thiab subwoofer rau tsib-channel amplifier. Lawv muaj tag nrho cov ntxaij lim dej rau kev kho cov khoom txuas nrog lawv, tab sis raws li txoj cai, lub zog ntawm cov amplifiers yog me me.

Thaum kawg, kuv xav hais cov lus hauv qab no. Yog tias koj tshiab rau lub tsheb suab thiab xav kom tau txais cov suab zoo, sib npaug, peb qhia koj xaiv plaub-channel amplifier. Nrog nws, koj tuaj yeem txuas cov hais lus pem hauv ntej thiab ib qho passive subwoofer. Qhov no yuav muab koj qhov zoo tshaj plaws pem hauv ntej, thaub qab los ntawm subwoofer txuas.

Amplifier zog.

Lub zog yog ib qho tseem ceeb tshaj plaws. Ua ntej, cia peb xam seb qhov txawv ntawm qhov ntsuas thiab lub zog siab tshaj plaws yog dab tsi. Lub tom kawg, raws li txoj cai, yog qhia nyob rau hauv lub cev ntawm lub amplifier, nws tsis sib haum mus rau qhov tseeb thiab yog siv raws li ib tug promo pass. Thaum muas, koj yuav tsum tau them sai sai rau qhov ntsuas hluav taws xob (RMS). Koj tuaj yeem saib cov ntaub ntawv no hauv cov lus qhia, yog tias tus qauv hais lus paub, koj tuaj yeem pom cov yam ntxwv hauv Is Taws Nem.

Tam sim no ob peb lo lus yuav ua li cas xaiv lub hwj chim ntawm lub amplifier thiab hais lus. Koj puas xav kawm ntxiv txog kev xaiv tus neeg hais lus? Nyeem tsab xov xwm "yuav ua li cas xaiv lub tsheb acoustics". Lub tsheb hais lus kuj muaj lub zog ntsuas, hauv cov lus qhia nws raug xa mus rau RMS. Ntawd yog, yog tias lub suab nrov muaj lub zog ntsuas ntawm 70 watts. Ces lub nominal hwj chim ntawm lub amplifier yuav tsum yog tib yam, los ntawm 55 mus rau 85 watts. Piv txwv li ob, hom amplifier xav tau rau lub subwoofer? Yog tias peb muaj lub subwoofer nrog lub zog ntsuas (RMS) ntawm 300 watts. Lub hwj chim ntawm lub amplifier yuav tsum yog 250-350 watts.

Tshooj xaus. Ntau lub zog yeej zoo, tab sis koj yuav tsum tsis txhob caum tom qab nws, vim tias muaj cov amplifiers nrog lub zog tsawg, thiab lawv ua si zoo dua thiab nrov dua li tsis kim tab sis nrog qee qhov kev ua tau zoo.

Tus tsim lub npe.

 

Thaum muas lub amplifier, nws yog ib qho tseem ceeb heev uas yuav tsum tau them sai sai rau qhov chaw tsim khoom tsim nws. Yog tias koj yuav cov khoom siv tes ua, koj tsis tuaj yeem suav cov suab nrov zoo. Nws yog qhov zoo tshaj plaws los tig rau cov npe vwm uas tau nyob hauv kev ua lag luam ntev thiab twb tau txais kev hwm thiab muaj txiaj ntsig rau lawv lub koob npe nrov. Piv txwv li, cov tuam txhab xws li Hertz, Alpine, DLS, Focal. Los ntawm kev siv nyiaj ntau dua, koj tuaj yeem tig koj cov xim rau cov hom xws li; Alphard, Blaupunkt, JBL, Ural, Swat, thiab lwm yam.

Txiav txim siab rau qhov kev xaiv ntawm amplifier? Cov tshooj tom ntej uas yuav pab tau rau koj yog "yuav ua li cas txuas lub tsheb amplifier."

Tau kawg, cov no tsis yog txhua qhov ntsuas uas koj yuav tsum tau them sai sai rau thaum xaiv lub amplifier, tab sis lawv yog cov tseem ceeb. Ua raws li cov lus pom zoo tau teev tseg hauv tsab xov xwm, koj tuaj yeem xaiv lub suab nrov zoo rau koj lub suab. Peb vam tias peb tau teb koj cov lus nug txog yuav ua li cas xaiv lub amplifier rau cov neeg hais lus lossis lub subwoofer, tab sis yog tias koj tseem muaj cov ntsiab lus tsis meej lossis xav tau, peb yuav zoo siab los teb nws hauv cov lus hauv qab no!
