5. Ukungazinzi kwamandla kagesi esizeni
Kwesinye isikhathi i-voltage endaweni yesehlakalo ishintshashintsha isuka phezulu iye phansi, okuzokwenza ukuthi isipika sishise.I-voltage engazinzile ibangela ukuthi izingxenye zishise.Uma i-voltage iphezulu kakhulu, i-amplifier yamandla idlula i-voltage eningi, okuzokwenza ukuthi isipika sishise.
6.Ukusetshenziswa okuxubile kwezikhulisamandla ezahlukene
I-EVC-100 Trs Professional Karaoke Amplifier
Ebunjiniyela, kuvame ukuba nesimo esinjalo: ama-amplifiers amandla emikhiqizo ehlukene namamodeli ahlanganisiwe.Kunenkinga enganakwa kalula-inkinga yokuzwela okokufaka kwesikhulisi samandla.Kukhona enye inkinga evame ukunganakwa, okungukuthi, izikhulisamandla zamandla afanayo kanye namamodeli ahlukene angase abe nama-voltages okuzwela okungahambisani.
I-FU-450 Professional Digital Echo Mixer Power Amplifier
Isibonelo, amandla okukhiphayo ama-amplifier amabili angu-300W, ukuzwela okokufaka kwe-A power amplifier ngu-0.775V, kanye nokuzwela okokufaka kwe-amplifier yamandla ka-B kungu-1.0V, khona-ke uma izikhulisamandla ezimbili zithola isignali efanayo ngesikhathi esisodwa. , lapho i-voltage yesignali ifinyelela ku-0.775V, Imiphumela ye-amplifier yamandla Ifinyelele ku-300W, kodwa ukukhishwa kwe-amplifier yamandla B kufinyelele ku-150W kuphela.Qhubeka ukhuphule izinga lesignali.Lapho amandla esignali efinyelela ku-1.0V, isikhulisi samandla A sasilayishwe kakhulu, futhi isikhulisi samandla B sisanda kufinyelela emandleni okukhiphayo alinganiselwe angu-300W.Esimeni esinjalo, nakanjani izodala umonakalo kuyunithi yesipika exhunywe kusiginali yokulayisha ngokweqile.
Uma izikhulisamandla ezinamandla afanayo kanye nama-voltage ahlukene okuzwela kuxutshwa, izinga lokufakwayo lesikhulisamandla esinokuzwela okuphezulu kufanele lincishiswe.Ukuhlanganiswa kungafinyelelwa ngokulungisa izinga lokuphumayo lemishini engaphambili noma ukunciphisa i-potentiometer yokufaka ye-amplifier yamandla ngokuzwela okuphezulu.
E-48 China Professional Amplifier Brands
Isibonelo, ama-amplifiers amabili angenhla angama-300W okukhipha amandla okukhulisa amandla, i-voltage ezwelayo kwenye ingu-1.0V, kanti enye ingu-0.775V.Ngalesi sikhathi, nciphisa izinga lokufakwayo le-amplifier engu-0.775V ngama-decibel angu-3 noma vula inkinobho yezinga le-amplifier Ibeke endaweni -3dB.Ngalesi sikhathi, lapho ama-amplifiers amabili efaka isignali efanayo, amandla okukhiphayo azofana.
7.Isignali enkulu inqanyulwa khona manjalo
I-DSP-8600 I-Karaoke Digital Processor
Ku-KTV, izikhathi eziningi izihambeli ezisebhokisini noma u-DJ zinomkhuba omubi kakhulu, okungukuthi, ukusika izingoma noma ukuthulisa umsindo ngaphansi kwengcindezi enkulu, ikakhulukazi uma udlala i-Di, kulula ukubangela ukuba ikhoyili yezwi ye-woofer inqamuke. noma ushise.
