5. Ukungazinzi kombane kwindawo
Ngamanye amaxesha i-voltage kwindawo yesiganeko iyatshintshatshintsha ukusuka phezulu ukuya ezantsi, nto leyo eya kubangela ukuba isithethi sitshise. I-voltage engaguqukiyo ibangela ukuba izinto zitshise. Xa i-voltage iphezulu kakhulu, i-power amplifier idlula i-voltage eninzi kakhulu, nto leyo eya kubangela ukuba isithethi sitshise.
6. Ukusetyenziswa okuxutyiweyo kwee-amplifier zamandla ezahlukeneyo
I-EVC-100 Trs Professional Karaoke Amplifier
Kwinjineli, kukho imeko enjalo rhoqo: ii-power amplifier zeempawu ezahlukeneyo kunye neemodeli ziyaxutywa. Kukho ingxaki enokungahoywa lula-ingxaki yovakalelo lokufaka lwe-power amplifier. Kukho enye ingxaki edla ngokungahoywa, oko kukuthi, ii-power amplifier zamandla afanayo kwaye iimodeli ezahlukeneyo zinokuba ne-sensitivity voltages ezingahambelaniyo.
I-FU-450 Professional Digital Echo Mixer Power Amplifier
Umzekelo, amandla okukhupha amandla e-amplifiers ezimbini zamandla yi-300W, uvakalelo lokufaka lwe-amplifier yamandla yi-0.775V, kwaye uvakalelo lokufaka lwe-amplifier yamandla ye-B yi-1.0V, ngoko ke ukuba ii-amplifiers ezimbini zamandla zifumana isignali efanayo ngexesha elinye, xa i-voltage yesignali ifikelela kwi-0.775V, i-amplifier yamandla ye-A ifikelela kwi-300W, kodwa i-output ye-amplifier yamandla B ifikelele kwi-150W kuphela. Qhubeka unyusa inqanaba lesignali. Xa amandla esignali efikelela kwi-1.0V, i-amplifier yamandla A yayigcwele kakhulu, kwaye i-amplifier yamandla B ifikelele kumandla okukhupha alinganiselweyo angama-300W. Kwimeko enjalo, ngokuqinisekileyo iya kubangela umonakalo kwiyunithi yesithethi eqhagamshelwe kwisignali yokugqithisa.
Xa zidityanisiwe ii-amplifiers zamandla ezinamandla afanayo kunye nee-voltages ezahlukeneyo zovakalelo, inqanaba lokungena le-amplifier yamandla enovakalelo oluphezulu kufuneka lincitshiswe. Ukumanyaniswa kunokufezekiswa ngokulungisa inqanaba lokukhupha lesixhobo sangaphambili okanye ukunciphisa i-potentiometer yokufaka ye-amplifier yamandla enovakalelo oluphezulu.
Iimpawu ze-E-48 China Professional Amplifier
Umzekelo, ezi amplifiers zimbini zingasentla zii-300W output power amplifiers, i-sensitivity voltage yesinye yi-1.0V, kwaye esinye yi-0.775V. Ngeli xesha, yehlisa inqanaba lokufaka le-amplifier ye-0.775V ngee-decibels ezi-3 okanye ujike iqhosha le-amplifier. Yibeke kwindawo ye--3dB. Ngeli xesha, xa ii-amplifier ezimbini zifaka isignali efanayo, amandla okukhupha aya kufana.
7.Isignali enkulu iqhawuka ngoko nangoko
Iprosesa yeDijithali yeKaraoke ye-DSP-8600
Kwi-KTV, amaxesha amaninzi iindwendwe ezisebhokisini okanye i-DJ zinemikhwa emibi kakhulu, oko kukuthi, zinqumle iingoma okanye zithule isandi phantsi koxinzelelo olukhulu, ingakumbi xa kudlala i-Di, kulula ukubangela ukuba i-voice coil ye-woofer iqhawuke okanye itshiswe.
Iprosesa ye-Audio yeDijithali ye-DAP-4080III yaseTshayina
Isignali yesandi ifakwa kwisithethi ngendlela yangoku, kwaye isithethi sisebenzisa amandla e-electromagnetic ukutyhala ikhowuni yephepha ukuze ihambe ngasemva nangaphambili ukuze umoya ungcangcazele ube sisandi. Xa i-input yesignali inqanyulwa ngequbuliso ngexesha lentshukumo enkulu, kulula ukubangela ukulahleka kwamandla okubuyisela emva kokuba intshukumo ifikelele kwinqanaba elithile, ukuze iyunithi yonakale.
