I-amplifier inhliziyo nomoya wesistimu yomsindo.I-amplifier isebenzisa i-voltage encane (amandla kagesi).Ibe isiyiphakela ibe yi-transistor noma ishubhu ye-vacuum, esebenza njengeswishi futhi ivule / ivale ngesivinini esikhulu kuye nge-voltage ekhulisiwe evela kumandla ayo.Lapho ukunikezwa kwamandla kwe-amplifier kunikezwa, amandla angena (isignali yokufaka) ngesixhumi sokufaka futhi akhuliswe ezingeni eliphezulu le-voltage.Lokhu kusho ukuthi isignali yamandla aphansi evela ku-amplifier yangaphambili iphakanyiselwa ezingeni elanele ukuze isipikha noma ama-headphone akhiqize umsindo, okusivumela ukuthi silalele umculo ngezindlebe zethu.

Iziteshi ezi-4 isikhulisi samandla esikhulu sombukiso wasendlini noma wangaphandle

Isimiso Sesikhulisi Samandla

Umthombo womsindo udlala izinhlobonhlobo zezimpawu zomsindo ukukhulisa ibhokisi lomsindo.

Njenge-Class D Magnum

Isikhulisi samandla se-Class-D siyimodi yokukhulisa lapho i-elementi ye-amplifier isesimweni sokushintsha.

Akukho okokufaka kwesignali: i-amplifier esimweni sokunqanyulwa, akukho ukusetshenziswa kwamandla.

Kukhona okokufaka kwesignali: Isignali yokufaka yenza i-transistor ingene esimweni sokugcwala, i-transistor ivula iswishi, ukunikezwa kwamandla nomthwalo kuxhumeke ngokuqondile.

I-amplifier Yamandla Yekilasi D yesipikha esichwepheshile

Amaphuzu abalulekile okukhetha nokuthenga

1.Okokuqala ukubona ukuthi i-interface iphelele yini

Isixhumi esibonakalayo esiyisisekelo kakhulu sokufaka nokukhiphayo okufanele isikhulisi samandla se-AV sihlanganise okulandelayo: i-coaxial, i-fiber optical, i-RCA yokufaka iziteshi eziningi zesixhumi esibonakalayo sokufaka isignali yedijithali noma yomsindo we-analog;i-horn output interface yesignali yokuphumayo ukuya kumsindo.

2.Okwesibili ukubona ukuthi ifomethi yomsindo ozungezile iphelele yini.

Amafomethi omsindo ozungezile adumile yi-DD ne-DTS, womabili angamashaneli angu-5.1.Manje lawa mafomethi amabili athuthukiswe ku-DD EX kanye ne-DTS ES, womabili ayi-6.1channel.

3.Bona ukuthi wonke amandla esiteshi angalungiswa ngokuhlukana

Amanye ama-amplifiers ashibhile ahlukanisa iziteshi ezimbili zibe iziteshi ezinhlanu.Uma isiteshi sikhulu, sizoba sikhulu futhi sibe sincane, futhi i-AV amplifier efaneleke ngempela ingalungiswa ngokuhlukana.

4.bheka isisindo se-amplifier.

Ngokuvamile, kufanele sizame konke okusemandleni ethu ukukhetha uhlobo olusindayo lomshini, isizathu siwukuthi umshini osindayo ingxenye yokuqala yokuphakelwa kwamandla inamandla, isisindo esiningi sesikhulisi samandla sivela kumandla kagesi kanye ne-chassis, okokusebenza kusinda kakhulu. , okusho ukuthi inani le-transformer elisetshenziswa nguye likhulu, noma i-capacitance enamandla amakhulu isetshenziswa, okuyindlela yokuthuthukisa ikhwalithi ye-amplifier.Okwesibili, i-chassis iyasinda, impahla kanye nesisindo se-chassis kunezinga elithile lomthelela emsindweni.I-chassis eyenziwe ngezinto ezithile iyasiza ekuhlukaniseni amaza omsakazo kude nesekhethi ku-chassis nasemhlabeni wangaphandle.Isisindo se-chassis siphezulu noma isakhiwo sizinzile, futhi singagwema ukudlidliza okungadingekile kwemishini futhi kuthinte umsindo.Okwesithathu, i-amplifier yamandla esindayo kakhulu, impahla ngokuvamile inothile futhi iqinile.
