- Ukongeza kumsebenzi wokuqhuba ukuqinisa isandisi-lizwi ngophawu olwandisiweyo lwe-amplifier yamandla eqhelekileyo, Ingacinezela ngempumelelo ukugquma kwendawo, ukuqinisekisa umgangatho wokudluliselwa kwelizwi, nokuba kwimeko-bume kukho amaxesha amabi, kodwa ingayicinezela kakhulu ukugquma umva ukukhusela izixhobo zesandi aziyi kutsha ngenxa yokugquma.

- Ngokwemisebenzi, ngokwemisebenzi eyahlukeneyo, ine-pre-amplifier (ekwaziwa njengesigaba sangaphambili), i-power amplifier (ekwaziwa njengesigaba seposi) kunye ne-amplifier edibeneyo. I-Power amplifier isetyenziselwa ukuphucula amandla esignali ukuqhuba isandi sesixhobo se-elektroniki. Akukho kukhetha umthombo wesignali, i-amplifier yokulawula ivolumu.

- Ngokweentlobo ezahlukeneyo zeetyhubhu ze-power amplifier, inokwahlulwa ibe ngumatshini we-duct kunye nomatshini wamatye. Umatshini wamatye si-amplifier esisebenzisa ii-transistors. Ngokweendlela ezahlukeneyo zokusetyenziswa, inokwahlulwa ibe yi-AV amplifier, i-Hi-Fi amplifier. I-AV power amplifier yenzelwe ngokukodwa iinjongo zethiyetha yasekhaya kwaye i-amplifier ngokubanzi ineziteshi ezingaphezu kwe-4 kunye nomsebenzi wokwahlula isandi esijikelezayo, kunye nesikrini sokubonisa. Injongo ephambili yolu hlobo lwe-power amplifier kukudala isiphumo sesandi sendawo yefilimu yokwenyani kwaye ivumele abaphulaphuli bafumane isiphumo se-cinema.

Uthotho lwe-AX 400/600/800W Isandisi-lizwi sobuchwephesha esineetshaneli ezimbini

Indima ye-Power Amplifier

Umsebenzi we-power amplifier kukwandisa isignali ebuthathaka evela kumthombo wesandi okanye kwi-pre-amplifier kunye nokukhuthaza isandi sesithethi. I-power amplifier yenkqubo yesandi elungileyo iyimfuneko.

I-Power amplifier, lolona sapho lukhulu kuzo zonke iintlobo zezixhobo zesandi, indima ephambili kukwandisa igalelo lesignali elibuthathaka elivela kwizixhobo zesandi, kunye nokuvelisa amandla aneleyo okukhuthaza isithethi ukuba sidlale isandi. Ngenxa yokuqwalaselwa kwamandla, ukungakwazi ukujikeleza, ukuphambuka, amandla kunye neendlela ezahlukeneyo zokusetyenziswa kunye nemisebenzi yokulungisa ulawulo, ii-power amplifier ezahlukeneyo zahlukile kwindlela yokucubungula isignali yangaphakathi, uyilo lwesekethe kunye netekhnoloji yemveliso.
