Ukuxhobisainkqubo yesandiUkuba nee-amplifier ezifanelekileyo kubalulekile ekuphuculeni amava esandi. Ngezantsi, siza kuxoxa ngokweenkcukacha ngendlela yokukhetha kunye nokudibanisa ii-amplifier zenkqubo yakho yesandi, sinethemba lokubonelela ngeengcebiso ezibalulekileyo zokuphucula inkqubo yakho yesandi.
1. Qonda ulwazi olusisiseko lwee-amplifiers zamandla
I-amplifier, ekwaziwa ngokuba yi-isikhulisi samandla, yenye yezona zinto ziphambili kwiinkqubo zesandi. Umsebenzi wayo ophambili kukwandisa imiqondiso yesandi ukuqhuba izithethi ukuba zivelise isandi. Ngokwemisebenzi eyahlukeneyo yamandla, ii-amplifiers zamandla zinokwahlulwa zibe zezi ntlobo zilandelayo:
I-Amplifier edibeneyo: Idibanisa imisebenzi yokukhulisa i-front-end kunye ne-back-end, ifanelekile ukusetyenziswa ekhaya.
Isandisi-mandla sangaphambi/samandla:umxubeisikhulisiinoxanduva lokulawula ivolumu kunye nokukhetha umthombo wesandi, ngelixa i-post amplifier inoxanduva lokukhulisa isignali. Ihlala isetyenziswa kwiinkqubo zesandi eziphezulu.
I-Power Amplifier: I-post amplification ecocekileyo, efanelekileyo kwizicelo ezinkulu.
2. Chonga iimfuno zamandla ze-amplifier
Inyathelo lokuqala ekukhetheni i-amplifier kukufumanisa iimfuno zamandla ayo, ezixhomekeke kwiiparameter zesithethi sakho kunye nendawo yokusetyenziswa. Ngokubanzi:
Uvakalelo lweSithethi: Kubhekiselele ekusebenzeni kakuhle kwesithethi, okulinganiswe nge-dB. Okukhona uvakalelo luphezulu, kokukhona isandisi-mandla esifunekayo sincinci.
I-impedance yesithethi: idla ngokuba yi-4 Ω, 6 Ω, 8 Ω. I-amplifier kufuneka ihambelane ne-impedance yesithethi, kungenjalo inokubangela ukuphazamiseka okanye umonakalo kwisixhobo.
Ubungakanani begumbi kunye nendawo yokusetyenziswa:Izikhulisi zamandla aphezuluziyafuneka ukuze zisetyenziswe kumagumbi amakhulu okanye ngaphandle.
Ngokwesiqhelo, amandla e-amplifier kufuneka abe ngaphezu kwamandla esithethi ngokuphindwe kayi-1.5 ukuya kwezi-2 ukuqinisekisa amandla aneleyo okuqhuba isithethi kwaye kushiyeke umda othile ukuze kuthintelwe ukuphazamiseka.
3. Cinga ngomgangatho wesandi kunye nesandi
Ukongeza ekufanisweni kwamandla, umgangatho wesandi kunye nokubetha kwesandi sesandi nazo zizinto ezibalulekileyo ekukhetheni. Iimpawu ezahlukeneyo kunye neemodeli zesandisi-lizwi zineempawu ezahlukeneyo zesandi, ezinye zifudumele kwaye ezinye zipholile. Kucetyiswa ukuba umamele iziphumo zokwenyani zeempawu ezahlukeneyo kunye neemodeli ngaphambi kokuba uthenge, ukuze ufumane isandisi-lizwi esifanelana kakuhle nezinto ozikhethayo zokumamela.
4. Gxila kwimisebenzi kunye neendlela zokunxibelelana
Ukongeza kumsebenzi osisiseko wokukhulisa, ii-amplifier zanamhlanje zinemisebenzi eyahlukeneyo eyongezelelweyo kunye ne-interfaces, ezinje:
Ii-interfaces zokufaka: kuquka i-RCA, i-XLR, i-fiber optic, i-coaxial, i-HDMI, njl.njl., ukuqinisekisa ukuhambelana nesixhobo sakho sesandi.
Iimpawu ezingenazingcingo: ezifana neBluetooth kunye neWiFi, okwenza kube lula ukuqhagamshela izixhobo eziphathwayo kunye nokusasaza imidiya.
Imisebenzi yokucubungula isandi: efana ne-equalizer, ukucubungula isandi esijikelezileyo, njl.njl., ukuphucula umgangatho wesandi.
5. Uhlobo kunye nohlahlo-lwabiwo mali
Xa ukhetha i-amplifier, uphawu kunye nohlahlo lwabiwo-mali nazo zizinto ezibalulekileyo ezingenakuze zityeshelwe. Uphawu oludumileyo olunomgangatho wemveliso oqinisekisiweyo, kodwa ngexabiso eliphezulu. Kubasebenzisi abanebhajethi encinci, banokukhetha iimpawu zasekhaya ezinexabiso eliphezulu.
isishwankathelo
Ukuxhobisa inkqubo yesandi nge-amplifier efanelekileyo kufuna ukuqwalaselwa kwezinto ezininzi ezifana nokuhambelana kwamandla, umgangatho wesandi, ujongano olusebenzayo, kunye nohlahlo lwabiwo-mali lwegama. Ndiyathemba ukuba umxholo ongentla ungakunika isikhokelo, ukuze ube nobuchule ngakumbi ekukhetheni nasekuhambelaniseni ii-amplifier, kwaye wonwabele amava omculo akumgangatho ophezulu.
Khumbula, amava okwenyani okumamela ngawona abalulekileyo. Ungazama ukumamela kwiivenkile ezibonakalayo rhoqo ukuze ufumane isicwangciso sokudibanisa esifanelekileyo kuwe. Inkqubo yesandi ene-amplifier ibubugcisa kunye nesayensi.
