Uma kukhulunywa ngokuthiimishini yomsindo, i-amplifier idlala indima ebalulekile ekunqumeni ikhwalithi yomsindo iyonke yesistimu. Phakathi kwemininingwane eminingi edingekayochaza ukusebenza kwe-amplifier, ububanzi bempendulo yemvamisa bungenye yezindlela ezibaluleke kakhulu. Ukuqonda ukuthi ububanzi bempendulo yemvamisa buthinta kanjaniikhwalithi yomsindokungasiza abantu abathanda ukulalela kanye nezilaleli ezivamile ukuthi benze izinqumo ezinolwazi lapho bekhetha imishini yokulalela.

Kuyini impendulo yemvamisa?

Impendulo yemvamisa ibhekisela ebangeni lamaza angase akhiqizwe ngempumelelo yi-amplifier. Ngokuvamile ilinganiswa nge-Hertz (Hz) futhi ivezwe njengobubanzi, njenge-20 Hz kuya ku-20 kHz. Lolu bubanzi luhlanganisa ububanzi bamaza azwakalayo kubantu futhi ngokuvamile lubhekwa njengolusukela ku-20 Hz (i-bass ephansi kakhulu) kuya ku-20 kHz (i-treble ephezulu kakhulu). I-amplifier enebanga lokuphendula imvamisa ebanzi ingakhiqiza ububanzi obubanzi, ithuthukise kakhulu ulwazi lokulalela.

Ukubaluleka Kobubanzi Bokuphendula Okuvamile

1. Ukukhiqizwa kwe-Bass: Ingxenye ephansi ye-frequency spectrum, ngokuvamile engaphansi kwe-100 Hz, yilapho kuhlala khona ama-bass frequency. I-amplifier engakwazi ukukhiqiza kabusha la ma-frequency aphansi izoholela ekucebeni okukhulu, okukhulu.umuzwa womsindo ojulile.Ngezinhlobo ezidingai-bass ejulile, njengomculo we-elekthronikhi, we-hip-hop, noweklasikhi, i-amplifier enempendulo yemvamisa efinyelela ku-20 Hz ingathuthukisa kakhulu ikhwalithi yomsindo.

2. Ukucaca Kwebanga Eliphakathi: Amaza omsindo aphakathi (cishe angu-300 Hz kuya ku-3 kHz) abalulekile ekucaciseni izwi kanye nokushaya kwezwi kwemvelo kwezinsimbi zomculo. I-amplifier ehamba phambili kulolu hlu iqinisekisa ukuthi amazwi nezinsimbi zomculokuzwakale kucacilefuthi kufana nokuphila. Uma impendulo yemvamisa ikhawulelwe kuleli banga, umsindo uzoba mdaka futhi ungacaci, okuthinta ulwazi lokulalela lonke.

3. Imininingwane ye-Treble: Amaza aphezulu, ikakhulukazi lawo angaphezu kwe-3 kHz, anegalelo emininingwaneni nasekucaceni komsindo. Izinsimbi zomculo ezifana nama-cymbals, ama-flute, nama-violin zikhiqiza imisindo kulolu hlu. I-amplifier engaphinda ngokunembile lawa maza inganikeza isikhala nemininingwane, ithuthukise ikhwalithi yomsindo iyonke. Impendulo enganele yamaza amaningi kuhlu lwe-treble ingabangela ukufiphala noma ukucasuka.umsindo ongaphili.

Indlela impendulo yemvamisa ethinta ngayo ikhwalithi yomsindo

Uhla lwempendulo yemvamisa ye-amplifier luthinta ngqo ukuthi ikhiqiza kahle kangakanani izinhlobo ezahlukene ze-izimpawu zomsindo.Nazi ezinye zezindlela eziyinhloko impendulo yemvamisa ethinta ngazo ikhwalithi yomsindo:

1. Ukuhlanekezela Nokufaka Umbala: Uma i-amplifier ingakwazi ukuphinda ikhiqize amaza athile, ingase ilethe ukuhlanekezela noma umbala emsindweni. Isibonelo, uma i-amplifier ingakwazi ukuphatha amaza aphansi kahle, ingase ikhiqize i-bass ehlanekezelwe engenakho ukucaca. Lokhu kuhlanekezela kubonakala kakhulu ezindaweni eziyinkimbinkimbi lapho kudlala khona izinsimbi eziningi ngesikhathi esisodwa.

2. Uhla Oluguquguqukayo: Anububanzi obuguqukayo be-amplifierlibhekisela emehluko phakathi kwevolumu ethule kakhulu nenomsindo kakhulu engayikhiqiza. Ububanzi bempendulo yemvamisa ebanzi ngokuvamile busho ububanzi obukhulu obuguquguqukayo, okuvumela i-amplifier ukuthi iphathe ama-nuances amancane kanye nama-crescendos anamandla ngaphandle kokuphazamiseka. Leli khono libalulekile ezinhlotsheni ezithembele ekuhlukeni okuguquguqukayo, njengomculo weklasikhi kanye ne-jazz.

3. Impendulo Yesigaba: Impendulo yemvamisa ayibhekiseli kuphela ekuphakameni komsindo kumaza ahlukene, kodwa futhi ihilela impendulo yesigaba, okuyisikhathi sesikhathiamaza omsindoAma-amplifier anempendulo engemihle yesigaba angabangela izinkinga zesikhathi, okwenza umsindo ungahambisani noma ungavumelani. Lokhu kuyingozi kakhulu ekusethweni kwe-stereo, lapho ukuthwebula izithombe okunembile kanye nensimu yomsindo kubalulekile ku-isipiliyoni sokulalela esijulile.

4. Ukuhambisana ne izipikha: Impendulo yemvamisa ye-amplifier kumele futhi ihambisane nezipikha ezishayelayo. Uma i-amplifier inempendulo yemvamisa elinganiselwe, ingase ingasebenzisi ngokugcwele ukusebenza kwesipikha sekhwalithi ephezulu. Ngokuphambene nalokho, i-amplifier yekhwalithi ephezulu enempendulo yemvamisa ebanzi ingasebenzisa ngokugcwele ukusebenza kwesipikha ngamandla ayo aphezulu.

Ukukhetha i-Amplifier Efanele

Niniukukhetha i-amplifier, kubalulekile ukucabangela ububanzi bempendulo yemvamisa kanye nezinye izici ezifana nokuhlanekezelwa kwe-harmonic okuphelele (i-THD), isilinganiso sesignali-kuya-kumsindo (i-SNR), kanye nokukhipha amandla. I-amplifier esebenza kahle ayinayo nje impendulo yemvamisa ebanzi kodwa futhi nokuhlanekezelwa okuphansi kanyeamandla aphezulu okukhiphaukushayela izikhulumi ngempumelelo.

Kwabathanda ukuzwa umsindo, kunconywa ukulalela ama-amplifier ahlukene endaweni elawulwayo ukuze kuhlolwe ikhwalithi yomsindo wabo. Naka ukuthi i-amplifier iphinda kahle kangakanani i-bass, i-mid-range, kanye ne-treble frequency. I-amplifier enhle kufanele inikeze umsindo olinganiselayo kuyo yonke i-frequency spectrum, okuholela ekuhlangenwe nakho okumnandi kokulalela.

Ekuphetheni

Ngamafuphi, ububanzi bokuphendula imvamisa ye-amplifier buyinto ebalulekile ethinta kakhulu ikhwalithi yomsindo. Impendulo ebanzi yemvamisa ivumela ukukhiqizwa okungcono kwe-bass, ukucaca kwebanga eliphakathi, kanye nemininingwane ye-treble, konke okunikela ekuhlangenwe nakho kokulalela okujulile nokujabulisayo. Ngokuqonda ukubaluleka kokuphendula imvamisa, abathengi bangenza izinqumo ezinolwazi lapho bekhetha ama-amplifier, baqinisekise ukuthi bathola ikhwalithi yomsindo engcono kakhulu ezinhlelweni zabo zomsindo. Kungakhathaliseki ukuthi ungumlaleli ovamile noma ungumuntu othanda kakhulu i-audio, ukunaka impendulo yemvamisa kungathatha ulwazi lwakho lomsindo luye ezingeni elisha.
