KwanamuhlaIzinhlelo zomsindo,Akungabazeki ukuthi ama-amplifiers anye yezakhi ezibucayi kakhulu. Akunandaba kuphela ikhwalithi yomsindo, kepha futhi inquma ukusebenza okuphelele kanye nokuhlangenwe nakho komsebenzisi kohlelo. Le ndatshana izongena ezintweni eziyinhloko zeAmandla Amplifiersukukusiza uqonde ukuthi kungani lezi zinto zibaluleke kakhulu.
1. Ukukhishwa kwamandla: shayela inhliziyo yophondo
Eminye yemisebenzi esemqoka ye-amplifier ukuhlinzeka ngamandla anele okushayela isipika. Ukukhishwa kwamandla kunquma ukuthi uhlelo lomsindo lungagcina umsindo ocacile futhi ongaqondakali kumavolumu ahlukahlukene. Ukukhishwa kwamandla kwe-amplifier yamandla kuvame ukuvezwa kuma-watts (W). Ukukhetha i-amplifier efanele yamandla kudinga ukucatshangelwa kwamaphuzu alandelayo:
Amandla alinganiselwe kaSomlomo: Amandla we-amplifier kufanele afane namandla akalwe ngesipika. Amandla amancane kakhulu angadala ivolumu enganele nokuhlanekezela, kuyilapho amandla amaningi angalimaza isipika.
Usayizi wegumbi kanye nemvelo ye-acoustic: emakamelweni amakhulu noma ezindaweni ezinomsindo ompofu, ama-amplifiers aphezulu aphezulu ayadingeka ukuze aqinisekise ukumbozwa komqondo nokucacile.
Uhlobo lomculo kanye nemikhuba yokulalela: Abasebenzisi abakujabulela ukulalela umculo wobubanzi obunamandla angadinga ama-ampliferiers aphezulu ukuze alondoloze imininingwane namandla omculo asondelene namavolumu aphezulu.
2. Ukuhlanekezela: Ukubulala okungabonakali kwekhwalithi yomsindo
Ukuhlanekezela kungenye yezinkomba ezibalulekile zokuhlola ikhwalithi yama-amplifiers wamandla. Kubhekiswa noma yiziphi izinguquko ezingadingekile kusiginali yokufaka ngesikhathi senqubo yokukhuphula. Kunezinhlobo ezilandelayo zokuhlanekezela:
Ukuhlanekezela kwe-Harmonic: imvamisa ekhiqizwa kaningi ngesikhathi sokukhuliswa kwesiginali. Lokhu kuhlanekezela kungenza umsindo ubungemvelo futhi uthinte ikhwalithi yomsindo.
Ukuhlanekezela phakathi kwe-Inter-Modulant: Kukhiqizwe imvamisa entsha lapho amasiginali amaza ahlukene ahlanganiswa kwi-amplifier, engaholela kumathoni angafuneki esignalini somsindo.
Ukuhlanekezela kwe-Trans-Wearch: Ubudlelwano obungeyona umugqa phakathi kokukhishwa kwe-amplifier yamandla kanye nesiginali yokufaka, okuvame ukwenzeka ngesikhathi esigcwele.
Idizayini ye-Amplifier enhle kakhulu izonciphisa lokhu kuhlanekezelwa futhi kunikeze ikhwalithi ecacile nenemvelo yomsindo.
3. Ukuphendula imvamisa: Ukubuyisa ububanzi nokujula komsindo
Ukuphendula imvamisa kubhekisele kububanzi bemvamisa yokuthi isikhulisi samandla singakhula ngempumelelo, sivame ukukalwa eHertz (Hz). I-amplifier efanelekayo kufanele ihlinzeke nge-amplification ebushelelezi futhi efanayo kulo lonke elaleli audio spectrum (imvamisa kusuka ku-20hz kuya ku-20KHZ). Ibhalansi yempendulo yemvamisa ithinta ngqo umphumela wokubuyiselwa komsindo:
Impendulo yemvamisa ephansi: Ithinta ukujula kanye nomthelela we-bass. Ama-amplifiers anokuphendula okuhle okuphansi okuphansi anganikeza imiphumela enamandla ye-bass.
Impendulo ye-Mid Frequency: Ithinta kakhulu ukusebenza kwezinsimbi nezinsimbi, futhi kuyingxenye ebalulekile yekhwalithi yomsindo.
Impendulo yemvamisa ephezulu: Ithinta ukucaciswa kanye nokusebenza kwemininingwane yamanothi aphezulu, kanye ne-amplifier yamandla enokuphendula okuthe xaxa okuphezulu kungenza umsindo ucace bha futhi ube namaqiniso.
4. Isiginali ku-Noise Ratio (SNR): Isiqinisekiso sekhwalithi yomsindo omsulwa
Isiginali ku-Noise Ratio iyinkomba ekala isilinganiso phakathi kwesiginali nomsindo owusizo esisayinweni kokuphuma kwe-amplifier yamandla, evame ukuvezwa kuma-decibel (DB). Isilinganiso esiphakeme se-Signal-to-Noise sisho ukuthi i-amplifier yamandla ikhiqiza umsindo omncane wangemuva lapho khulisa isiginali, kuqinisekiswe ubumsulwa bekhwalithi yomsindo. Ukukhetha i-amplifier yamandla enesilinganiso esiphakeme se-Signal-to-Noise kunganciphisa ukuphazanyiswa kokuzwa futhi kunikeze isipiliyoni sokulalela esicwilisa.
I-5. Umklamo wesekethe wamandla ama-amplifiers: itshe lokuzimisela ukusebenza
Umklamo wesifunda wangaphakathi we-amplifier yamandla athinta ngqo ukusebenza kwawo nekhwalithi yomsindo. Kunemiklamo eminingana ejwayelekile yesifunda:
I-Class a amplifier: ngekhwalithi ephezulu yomsindo kodwa ukusebenza okuphansi kakhulu, kufanelekile amasistimu womsindo aphezulu aphishekela ikhwalithi yomsindo wokugcina.
I-Class B Amplifier: Ukusebenza okuphezulu kepha ukuphambuka okubalulekile, okuvame ukusetshenziswa maphakathi nezinhlelo zomsindo eziphansi.
I-Class Ab Amplifier: Kuhlanganisa izinzuzo zazo zombili izigaba A neClass B, ngokusebenza kahle nekhwalithi yomsindo omuhle, futhi njengamanje ingumbono we-amplifier we-mainstream.
I-Class D Amplifier: Ngokusebenza kahle kakhulu nosayizi omncane, ilungele amadivayisi aphathekayo kanye nezinhlelo zanamuhla zeshashalazi yasekhaya.
Yonke imidwebo yesifunda inezinzuzo zayo nobunzima, futhi ikhethe uhlobo lwe-amplifier evumelana nezidingo zakho zibalulekile.
I-6. Imisebenzi kanye nezinhlaka ze-Power Amplifiers: Ukuhlangabezana Nezidingo Ezihlukahlukene
Ama-Amplifiers anamuhla awadingi nje ikhwalithi enhle kakhulu yomsindo, kodwa futhi adinga futhi ukuhlinzeka ngemisebenzi ecebile futhi axhumane nezindawo zokuzivumelanisa nezimo ezahlukahlukene zokusebenzisa. Ngokwesibonelo:
Izindawo eziningi zokufaka zokufaka, njenge-RCA, i-fiber optic, i-coaxial, i-HDMI, njll.
Ukuxhumana okungenantambo: njenge-Bluetooth ne-WI FI, elula ukuhlanganiswa namadivayisi eselula kanyeizinhlelo ezinhle zasekhaya.
Ukuxhaswa kwesiteshi okuningi: KufaneleIzinhlelo zeshashalazi yasekhaya, ukuhlinzeka ngesipiliyoni somsindo esicwilisa ngokwengeziwe.
Ukukhetha i-amplifier enhle kakhulu kudinga ukucatshangelwa okuphelele kwezinto ezifana nokukhipha amandla, ukuhlanekezela, ukuphendula imvamisa, isilinganiso se-Signal-to-Noise, ukuklanywa kwesifunda, ukusebenza kanye nokusebenza. Kungale ndlela kuphela lapho singaqinisekisa ukusebenza okuhle kakhulu nokuhlangenwe nakho komsebenzisi kohlelo lomsindo. Noma ngabe ungumthandi womculo noma umdlandla weshashalazi ekhaya, ukuqonda nokunaka lezi zinto ezibalulekile kuzokusiza ukhethe idivaysi ye-Amplifier evumelana kahle nawe, yenza konke okuhlangenwe nakho kokulalela kube yinjabulo.
