Lub amplifier yog lub plawv thiab tus ntsuj plig ntawm lub suab system. Lub amplifier siv lub zog me me (electromotive force). Nws mam li pub nws mus rau hauv lub transistor lossis lub tshuab nqus tsev vacuum, uas ua haujlwm zoo li qhov hloov pauv thiab tig rau / tawm ntawm kev kub ceev nyob ntawm qhov amplified voltage los ntawm nws lub hwj chim mov. Thaum lub hwj huam mov ntawm lub amplifier tau muab, lub hwj chim nkag mus rau (lub teeb liab input) los ntawm lub input connector thiab yog amplified mus rau ib tug ntau dua voltage theem. Qhov no txhais tau hais tias lub teeb liab hluav taws xob qis los ntawm lub tshuab hluav taws xob pem hauv ntej tau nce mus rau theem txaus rau tus neeg hais lus lossis lub mloog pob ntseg los tsim lub suab, tso cai rau peb mloog suab paj nruag nrog peb pob ntseg.

4 Channels loj fais fab amplifier rau sab hauv tsev lossis sab nraum zoov yeeb yam

Txoj Cai ntawm Fais Amplifier

Lub suab nrov plays ntau yam suab paj nruag los ua kom lub suab nrov nrov.

Zoo li Class D Magnum

Class-D fais fab amplifier yog hom amplification uas lub amplifier lub ntsiab nyob rau hauv lub xeev hloov.

Tsis muaj teeb liab tawm tswv yim: amplifier nyob rau hauv lub xeev txiav tawm, tsis muaj hwj chim noj.

Muaj lub teeb liab tawm tswv yim: Lub teeb liab input ua rau lub transistor nkag mus rau hauv lub xeev saturation, lub transistor tig rau ntawm tus tes hloov, lub hwj huam mov thiab lub load yog txuas ncaj qha.

Class D Power amplifier rau cov kws tshaj lij

Cov ntsiab lus tseem ceeb ntawm kev xaiv thiab yuav khoom

1.Qhov thawj yog saib yog tias lub interface tiav

Qhov yooj yim tshaj plaws cov tswv yim thiab cov zis interface uas AV fais fab amplifier yuav tsum muaj cov hauv qab no: coaxial, optical fiber, RCA multi-channel input interface rau cov tswv yim digital lossis analog suab teeb liab; horn output interface rau tso zis teeb liab rau suab.

2.Qhov thib ob yog saib seb lub suab ib puag ncig yog ua tiav.

Cov hom suab nrov ib puag ncig yog DD thiab DTS, ob qho tib si yog 5.1 raws. Tam sim no ob hom no tau tsim los rau DD EX thiab DTS ES, ob qho tib si yog 6.1channel.

3.Saib seb tag nrho cov channel fais fab tuaj yeem hloov kho cais

Qee qhov pheej yig amplifiers faib ob txoj hauv kev rau tsib txoj kab. Yog tias cov channel loj, nws yuav loj thiab me, thiab qhov tsim nyog AV amplifier tiag tiag tuaj yeem hloov kho nyias.

4.Saib qhov hnyav ntawm lub amplifier.

Feem ntau hais lus, peb yuav tsum sim peb qhov zoo tshaj plaws los xaiv lub tshuab hnyav dua, vim li cas cov cuab yeej hnyav dua thawj lub zog hluav taws xob muaj zog dua, feem ntau ntawm qhov hnyav ntawm lub tshuab hluav taws xob yog los ntawm cov khoom siv hluav taws xob thiab chassis, cov khoom siv hnyav dua, uas txhais tau hais tias tus nqi transformer siv los ntawm nws loj dua, lossis lub peev xwm loj dua yog siv, uas yog ib txoj hauv kev los txhim kho qhov zoo. Qhov thib ob, lub chassis hnyav, cov khoom siv thiab qhov hnyav ntawm lub chassis muaj qee qhov cuam tshuam rau lub suab. Lub chassis ua los ntawm qee cov ntaub ntawv yuav pab tau rau kev sib cais ntawm cov xov tooj cua yoj ntawm lub voj voog hauv lub chassis thiab lub ntiaj teb sab nraud. Qhov hnyav ntawm lub chassis yog siab dua lossis cov qauv ruaj khov dua, thiab nws tseem tuaj yeem zam qhov kev vibration tsis tsim nyog ntawm cov khoom siv thiab cuam tshuam rau lub suab. Thib peb, qhov hnyav zog amplifier, cov khoom siv feem ntau yog nplua nuj thiab ruaj khov.
