Kwihlabathi labantu abathanda isandi kunye neengcali, ii-amplifiers zidlala indima ebalulekileyo. Aziyonxalenye nje yenkqubo yesandi, kodwa zikwayimpembelelo yemiqondiso yesandi. Nangona kunjalo, ukugweba umgangatho we-amplifier akulula. Kweli nqaku, siza kujonga iimpawu eziphambili zee-amplifiers size sityhile indlela yokuvavanya umgangatho we-amplifier.

1. Ukusebenza komgangatho wesandi:

Okokuqala, umgangatho wesandi yenye yezona ndlela ziphambili zokuvavanya umgangatho we-amplifier. I-amplifier egqwesileyo kufuneka ikwazi ukubuyisela imiqondiso yesandi, inciphise ukugqwetheka kangangoko kunokwenzeka, kwaye igcine iimpawu zokuqala zesandi. Izalathisi eziphambili ziquka impendulo yefrikhwensi, inqanaba lokugqwetheka, umlinganiselo wesignali-kwingxolo, njl. I-amplifier elungileyo kufuneka ikwazi ukubonelela ngomgangatho wesandi ocacileyo, ocacileyo, noguquguqukayo, endaweni yokongeza imibala yayo okanye ukugqwetha imiqondiso yesandi.

2. Imveliso yamandla kunye nozinzo:

Ukuphuma kwamandla lolunye uphawu olubalulekileyo lovavanyo. I-amplifier egqwesileyo kufuneka ikwazi ukubonelela ngamandla aneleyo okuqhuba isithethi kwaye igcine uzinzo phantsi kweemeko ezahlukeneyo zomthwalo. Ukongeza kumandla aqhelekileyo, amandla aguqukayo, uzinzo, kunye nenqanaba lokuphambuka kwe-amplifier yamandla nazo kufuneka ziqwalaselwe. I-amplifier elungileyo kufuneka ikwazi ukusebenza kakuhle ngevolumu ephezulu kunye nevolumu ephantsi ngaphandle kokuphambuka okanye ukulahleka kwamandla.

3. Umgangatho wokwakha kunye nokuthembeka:

Umgangatho wokwakha kunye nokuthembeka kwee-amplifiers zamandla kuchaphazela ngokuthe ngqo ukusebenza kwazo kunye nobomi benkonzo. I-amplifier elungileyo kufuneka isebenzise izinto ezikumgangatho ophezulu kunye nezixhobo, kwaye idlule kubuchule obungqongqo kunye novavanyo. I-chassis ehlala ixesha elide, inkqubo yokupholisa esebenzayo, kunye nombane ozinzileyo zonke zizinto ezibalulekileyo kumgangatho wokwakha. Ukongeza, iisekethe ezilungileyo zokukhusela kunye nezihlanganisi ezithembekileyo nazo zizinto ezibalulekileyo ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwee-amplifiers zamandla.

 4. Uqhagamshelo kunye nomsebenzi:

Ii-amplifier zanamhlanje zihlala zineendlela ezahlukeneyo zonxibelelwano kunye nemisebenzi, njengokufaka okuninzi, uqhagamshelo lwenethiwekhi, ukucubungula ngedijithali, njl. I-amplifier elungileyo kufuneka ikwazi ukuhlangabezana neemfuno ezahlukeneyo zabasebenzisi kwaye ibonelele ngeendlela zonxibelelwano kunye nokusebenza ezilula. Ukongeza, iimpawu ezongezelelweyo ezifana nokulungiswa kwe-EQ, iziphumo zokucubungula isandi, njl. nazo zinokuba yenye yezinto abasebenzisi abaziqwalaselayo xa bekhetha i-amplifier.

5. Ingxelo yabasebenzisi kunye nodumo lwabo:

Okokugqibela, impendulo yomsebenzisi kunye nodumo lwe-amplifier brand nazo zizinto ezibalulekileyo ekuvavanyweni komgangatho we-amplifier. Ngokuphonononga uphononongo lwabasebenzisi, uphononongo lobuchwephesha, kunye nembali ye-brand, umntu unokuqonda ukusebenza kokwenyani kunye namava omsebenzisi we-amplifier. I-brand ethembekileyo idla ngokubonelela ngeemveliso ezithembekileyo ngakumbi kunye nenkonzo elungileyo emva kokuthengisa, nto leyo ikwayinto ebalulekileyo ekukhetheni i-amplifier elungileyo.

Ngamafutshane, ukuvavanya umgangatho we-power amplifier kufuna ukuqwalaselwa ngokubanzi kwezinto ezininzi ezifana nokusebenza komgangatho wesandi, imveliso yamandla, umgangatho wokwakha, uqhagamshelo kunye nokusebenza, kunye nempendulo yabasebenzisi. Kuphela xa ezi mpawu ziphambili zifezekisiwe apho i-power amplifier ingathathwa njengegqwesileyo. Ke ngoko, xa ukhetha i-power amplifier, akufuneki nje kuphela ukuba unike ingqalelo kwiinkcukacha zayo zobugcisa, kodwa kwakhona ukuqwalasela ukusebenza kwayo kunye namava omsebenzisi, ukuze ufumane imveliso efanelekileyo kwiimfuno zakho.
