5. Ukungazinzi kombane kwisiza
Ngamanye amaxesha i-voltage kwindawo yesiganeko iyatshintsha ukusuka phezulu ukuya ezantsi, nto leyo eya kubangela ukuba isithethi siphele. Amandla ombane angazinzanga abangela ukuba amalungu atshise. Xa i-voltage iphezulu kakhulu, i-amplifier yamandla idlula i-voltage eninzi, eya kubangela ukuba isithethi sitshise.
6.Ukusetyenziswa okuxutyiweyo kwezandisi zamandla ezahlukeneyo
EVC-100 Trs Professional Karaoke Amplifier
Kwinjineli, kukho rhoqo imeko enjalo: i-amplifiers yamandla yeempawu ezahlukeneyo kunye neemodeli zixutywe. Kukho ingxaki engahoywa ngokulula-ingxaki yobuntununtunu begalelo le-amplifier yamandla. Kukho enye ingxaki ehlala ingahoywa, oko kukuthi, i-amplifiers yamandla afanayo kunye neemodeli ezahlukeneyo zinokuba ne-voltages engahambelaniyo yovakalelo.
FU-450 Professional Digital Echo Umxhubi Amandla Amandla
Umzekelo, amandla aphumayo ezikhulisi zamandla ezimbini yi-300W, uvakalelo lwegalelo le-A amplifier yamandla yi-0.775V, kunye nobuntununtunu begalelo le-B amplifier yamandla yi-1.0V, ke ukuba i-amplifier zamandla ezibini zifumana umqondiso ofanayo ngaxeshanye, xa umbane wesiginali ufikelela ku-0.775V, I-amplifier yamandla ifikelele kwimveliso ye-B30W kuphela, yafikelela kwimveliso ye-B. 150W. Qhubeka ukwandisa inqanaba lomqondiso. Xa amandla omqondiso afikelela kwi-1.0V, iamplifier yamandla A yayigcwele kakhulu, kunye neamplifier yamandla B ifike kumandla aphumayo alinganisiweyo angama-300W. Kwimeko enjalo, ngokuqinisekileyo iya kubangela umonakalo kwiyunithi yesithethi eqhagamshelwe kwisiginali yokulayisha ngaphezulu.
Xa ii-amplifier zamandla ezinamandla afanayo kunye ne-voltage ezahlukeneyo zovakalelo zixutywe, inqanaba legalelo le-amplifier yamandla enovakalelo oluphezulu kufuneka lincitshiswe. Ukuhlanganiswa kunokufezekiswa ngokulungelelanisa umgangatho wokuphuma kwezixhobo zangaphambili okanye ukunciphisa i-potentiometer yegalelo le-amplifier yamandla kunye novakalelo oluphezulu.
E-48 China IiNgcaciso zeAmplifaya zoBuchule
Umzekelo, ezi amplifiers zimbini zingentla ziyi-300W imveliso yamandla ekhupha amandla ombane, amandla obuntununtunu yenye yi-1.0V, kwaye enye yi-0.775V. Ngeli xesha, nciphisa inqanaba legalelo le-0.775V amplifier nge-3 decibels okanye ujike i-knob yezinga le-amplifier Yibeke kwindawo -3dB. Ngeli xesha, xa i-amplifiers ezimbini zifakela umqondiso ofanayo, amandla okuphuma aya kufana.
7.Umqondiso omkhulu uqhawulwa ngoko nangoko
DSP-8600 Karaoke Digital Processor
Kwi-KTV, amaxesha amaninzi iindwendwe ezisebhokisini okanye i-DJ inomkhwa ombi kakhulu, oko kukuthi, ukusika iingoma okanye ukuthulisa isandi phantsi koxinzelelo olukhulu, ngakumbi xa udlala i-Di, kulula ukubangela ukuba i-coil yezwi ye-woofer ikhuphe okanye itshise.
DAP-4080III China Karaoke Professional Digital Audio Processor
Isignali ye-audio igalelo kwisithethi ngokusebenzisa indlela yangoku, kwaye isithethi sisebenzisa amandla ombane ukutyhala ikhowuni yephepha ukuya emva naphambili ukwenza umoya ungcangcazele ube sisandi. Xa igalelo lesignali linqunyulwa ngokukhawuleza ngexesha lokunyakaza okukhulu, kulula ukubangela ukulahlekelwa amandla okubuyisela emva kokuba ukunyakaza kufikelele kwinqanaba elithile, ukwenzela ukuba iyunithi yonakaliswe.
