5. Kurubuga rwa voltage idahungabana
Rimwe na rimwe, voltage kuri scene ihindagurika kuva hejuru kugeza hasi, nayo izatera umuvugizi gucana.Umuvuduko udahinduka utera ibice gutwika.Iyo voltage ari ndende cyane, imbaraga zongera imbaraga zinyura hejuru ya voltage nyinshi, bizatera umuvugizi gucana.
6.Gukoresha kuvanga imbaraga zinyuranye zongera imbaraga
EVC-100 Trs Yabigize umwuga Karaoke
Muri injeniyeri, akenshi usanga ibintu bimeze nkibi: imbaraga zongerera imbaraga ibirango bitandukanye na moderi bivanze.Hano hari ikibazo cyirengagijwe byoroshye-ikibazo cyo kwinjiza sensibilité ya power amplifier.Hariho ikindi kibazo gikunze kwirengagizwa, ni ukuvuga, imbaraga zongerera imbaraga imbaraga zimwe na moderi zitandukanye zishobora kugira voltage zidahuye.

Kurugero, ibisohoka imbaraga zibiri zongerera ingufu ni 300W, ibyinjira byinjira byingufu zingufu ni 0.775V, naho ibyinjira byinjira mumashanyarazi ya B ni 1.0V, hanyuma niba ingufu zombi zakira ikimenyetso kimwe icyarimwe. , iyo ibimenyetso bya voltage bigeze kuri 0.775V, Imbaraga zongera ingufu zageze kuri 300W, ariko ibisohoka byamashanyarazi B byageze kuri 150W gusa.Komeza wongere ibimenyetso byurwego.Iyo imbaraga za signal zigeze kuri 1.0V, amplifier A yaremerewe cyane, naho ingufu za B zongera ingufu za 300W.Mu bihe nk'ibi, byanze bikunze byangiza igice cya disikuru ihujwe nikimenyetso kirenze.
Iyo imbaraga zongerera imbaraga imbaraga zimwe hamwe na voltage zitandukanye zivanze zivanze, urwego rwinjiza rwingufu zongerera imbaraga hamwe na sensibilité nyinshi zigomba kwiyongera.Guhuriza hamwe birashobora kugerwaho muguhindura ibisohoka murwego rwibikoresho byimbere cyangwa kugabanya potentiometero yinjiza ya amplifier yingufu hamwe na sensibilité yo hejuru.
E-48 Ibicuruzwa byabigize umwuga byongerera imbaraga
Kurugero, ibyongeweho bibiri byavuzwe haruguru ni 300W bisohora ingufu zongera imbaraga, ibyiyumvo bya sensitivite ya 1.0V, naho ubundi ni 0.775V.Muri iki gihe, gabanya urwego rwinjiza rwa 0.775V amplifier kuri decibel 3 cyangwa uhindure urwego rwa amplifier urwego knob Shyira mumwanya wa -3dB.Muri iki gihe, iyo amplifier ebyiri zinjiza ikimenyetso kimwe, ibisohoka imbaraga bizaba bimwe.
7.Ikimenyetso kinini kirahagarikwa ako kanya
Muri KTV, inshuro nyinshi abashyitsi bari mu gasanduku cyangwa DJ bafite ingeso mbi cyane, ni ukuvuga guca indirimbo cyangwa gucecekesha amajwi munsi yumuvuduko mwinshi, cyane cyane iyo ukina Di, biroroshye gutera igiceri cyijwi ryubwoya. cyangwa gutwika.
DAP-4080III Ubushinwa Karaoke Yumwuga Utunganya amajwi
Ikimenyetso cyamajwi ninjiza mubavuga binyuze muburyo bugezweho, kandi uwatanze disikuru akoresha imbaraga za electromagnetic kugirango asunike impapuro kugirango yimuke inyuma kandi kugirango umwuka uhinduke mumajwi.Iyo ibimenyetso byinjira byaciwe gitunguranye mugihe kinini kinini, biroroshye gutera igihombo cyubushobozi bwo gukira nyuma yimikorere igeze kurwego runaka, kuburyo igice cyangiritse.
