Muri iki gihesisitemu y'amajwi,nta gushidikanya ko ari kimwe mu bintu bikomeye.Ntabwo bigira ingaruka gusa kumiterere yijwi, ahubwo inagena imikorere rusange nuburambe bwabakoresha ba sisitemu.Iyi ngingo izacengera mubintu by'ibanze byaimbaraga zongera imbaragakugufasha kumva impamvu ibi bintu ari ngombwa.
1. Ibisohoka ingufu: Twara umutima wihembe
Imwe mumikorere yingenzi ya amplifier nugutanga imbaraga zihagije zo gutwara disikuru.Imbaraga zisohoka zerekana niba sisitemu yijwi ishobora kugumana amajwi asobanutse kandi atagabanijwe kumajwi atandukanye.Imbaraga ziva mumashanyarazi zisanzwe zigaragara muri watts (W).Guhitamo imbaraga zongerewe imbaraga bisaba gusuzuma ingingo zikurikira:
Imbaraga zagereranijwe za disikuru: Imbaraga za amplifier zigomba guhuza imbaraga zapimwe za disikuru.Imbaraga nke cyane zishobora gutera amajwi adahagije no kugoreka, mugihe imbaraga nyinshi zishobora kwangiza abavuga.
Ingano yicyumba hamwe n’ibidukikije bya acoustique: Mu byumba binini cyangwa ibidukikije bifite amajwi mabi, imbaraga zongererwa imbaraga zirasabwa kugirango amajwi yuzuye kandi asobanutse.
Ubwoko bwumuziki hamwe ningeso zo gutegera: Abakoresha bakunda kumva umuziki uringaniye urashobora gukenera imbaraga zongererwa imbaraga kugirango bakomeze ibisobanuro hamwe nimbaraga za muzika ku bwinshi.
2. Kugoreka: Umwicanyi utagaragara wubwiza bwamajwi
Kugoreka ni kimwe mu bipimo byingenzi byo gusuzuma ubuziranenge bwongera ingufu.Yerekeza ku mpinduka zose zidakenewe mubimenyetso byinjira mugihe cyo kwagura.Hariho ubwoko bukurikira bwo kugoreka:
Kugoreka kwa Harmonic: Inshuro nyinshi zakozwe mugihe cyo kongera ibimenyetso.Uku kugoreka gushobora gutuma amajwi adasanzwe kandi akagira ingaruka kumajwi.
Kugoreka hagati ya modulasiyo: inshuro nshya yakozwe mugihe ibimenyetso byumurongo utandukanye bivanze muri amplifier, bishobora kuganisha kumajwi udashaka mubimenyetso byamajwi.
Kugoreka trans-imyitwarire: Isano itari umurongo hagati yumusaruro wimbaraga zongerera imbaraga nibimenyetso byinjira, mubisanzwe bibaho mugihe kirenze urugero.
Igishushanyo cyiza cya amplifier kizagabanya ibyo kugoreka no gutanga amajwi asobanutse kandi asanzwe.
3. Igisubizo cyinshyi: Kugarura ubugari nuburebure bwijwi
Igisubizo cyinshyi bivuga intera yumurongo imbaraga zongera imbaraga zishobora kwaguka neza, mubisanzwe bipimirwa muri Hertz (Hz).Amplifier nziza igomba gutanga amplification yoroheje kandi imwe murwego rwamajwi yose (mubisanzwe kuva 20Hz kugeza 20kHz).Impuzandengo yumurongo wibisubizo bigira ingaruka muburyo bwo kugarura amajwi:
Igisubizo gike gike: kigira ubujyakuzimu n'ingaruka za bass.Amplifiers hamwe nigisubizo cyiza gito-gishobora gutanga ingaruka zikomeye za bass.
Hagati yumurongo wo gusubiza: cyane cyane bigira ingaruka kumikorere yijwi nibikoresho, kandi nigice cyibanze cyubwiza bwamajwi.
Igisubizo cyumuvuduko mwinshi: Bigira ingaruka kumikorere no muburyo burambuye imikorere yinyandiko ndende, kandi imbaraga zongerera imbaraga hamwe nigisubizo cyiza cyinshi gishobora gutuma ijwi rirushaho gukorera mu mucyo kandi rifatika.
4. Ikimenyetso cyerekana urusaku (SNR): garanti yubwiza bwijwi
Ikimenyetso kuri Urusaku rw'Ijwi ni ikimenyetso cyerekana igipimo kiri hagati yikimenyetso cyingirakamaro n urusaku mu kimenyetso gisohora imbaraga zongera imbaraga, ubusanzwe kigaragara muri decibels (dB).Ikigereranyo kinini-cy-urusaku bivuze ko imbaraga zongera imbaraga zitanga urusaku ruto rwambere iyo rwongereye ibimenyetso, rwemeza ubuziranenge bwijwi.Guhitamo imbaraga zongerera imbaraga hamwe nikimenyetso kinini-cyerekana urusaku birashobora kugabanya kwumva no gutanga uburambe bwo gutegera.
5. Igishushanyo cyizunguruka cyingufu zongera imbaraga: ibuye ryimfuruka yo kugena imikorere
Igishushanyo mbonera cyimbere cyimbaraga zongerera imbaraga imikorere yacyo nuburyo bwiza bwijwi.Hariho ibishushanyo byinshi bisanzwe bizunguruka:
Icyiciro A amplifier: Hamwe nijwi ryiza ryiza ariko rikora neza, irakwiriye sisitemu yo mumajwi yohejuru ikurikirana amajwi meza.
Icyiciro cya B cyongera imbaraga: Gukora neza ariko kugoreka gukomeye, bikunze gukoreshwa hagati ya sisitemu yo hagati.
Icyiciro cya AB amplifier: Ihuza ibyiza byicyiciro cya A na B B, hamwe nubushobozi buhanitse hamwe nijwi ryiza ryiza, kandi kuri ubu ni igishushanyo mbonera cya amplifier.
Icyiciro cya D amplifier: Hamwe nubushobozi buhanitse nubunini buto, burakwiriye kubikoresho byimukanwa hamwe na sisitemu yo murugo igezweho.
Igishushanyo mbonera cyose gifite ibyiza n'ibibi, kandi guhitamo ubwoko bwa amplifier bujyanye nibyo ukeneye ni ngombwa.
6. Imikorere nintera yimbaraga zongera imbaraga: guhuza ibikenewe bitandukanye
Amplifiers zigezweho ntizisaba gusa amajwi meza, ariko kandi igomba gutanga imikorere ikungahaye hamwe ninteruro kugirango ihuze nuburyo butandukanye bwo gukoresha.Urugero:
Imigaragarire myinshi yinjiza, nka RCA, fibre optique, coaxial, HDMI, nibindi, byorohereza guhuza ibikoresho bitandukanye byamajwi.
Wireless connection: nka Bluetooth na Wi Fi, byoroshye guhuza nibikoresho bigendanwa kandisisitemu yo murugo ifite ubwenge.
Inkunga y'imiyoboro myinshi: ibereyesisitemu yo murugo, gutanga amajwi meza cyane.
Guhitamo amplifier nziza cyane bisaba gutekereza cyane kubintu nkibisohoka ingufu, kugoreka, gusubiza inshuro, kugereranya-urusaku, igishushanyo mbonera, imikorere, hamwe nintera.Gusa murubu buryo turashobora kwemeza imikorere myiza nuburambe bwabakoresha sisitemu yamajwi.Waba ukunda umuziki cyangwa ukunda inzu yimikino, gusobanukirwa no kwitondera ibi bintu byingenzi bizagufasha guhitamo ibikoresho byongera imbaraga bikwiranye neza, bigatuma uburambe bwo gutega amatwi bushimisha.
