Izixhobo zeKaraoke ukongeza kwizithethi, izixhobo zomculo zibaluleke kakhulu, umgangatho wesandisi ngokwawo nawo ubaluleke kakhulu. Umsebenzi weKTV kufuneka udityaniswe nobungakanani begumbi lakho kunye nezinto zokuhombisa. Iindawo ezahlukeneyo zamagumbi kufuneka zisebenzise izixhobo zokukhulisa amandla. Nika ingqalelo ukuthelekiswa kwesikhulisi samandla kunye nesithethi.

Amandla esixhobo sokukhulisa amandla edlala ikaraoke eyilelwe kwinqanaba lokuqala ngokubanzi sincinci, kwaye izithethi ezixhasayo zizithethi zamandla ezincinci ezinemvakalelo ephezulu. Eyona ngxaki ixhaphakileyo kukukhwaza ngempendulo. Isizathu kukuba ugcino lwamandla alonelanga xa ivolumu iphezulu, okukhokelela kukuphazamiseka kwemiqondiso. Ukongeza, ukugqwethwa kwesithethi esinovakalelo oluphezulu yingxelo, kunye nokugqwetha kukhuliswe ngokujikeleza, kukhokelela kwingxolo yengxelo. Ngokomgaqo, oyena nobangela uphambili wokubhomboloza kwengxelo kukugqwetha. Ukunciphisa ukugqwetha kunokunciphisa ukubakho kwengxelo yengxolo. Nangona kunjalo, akunakuthethwa ukuba akuyi kubakho mpendulo yengxelo. Kuphela kuluhlu lwenzuzo olukhoyo, xa inzuzo inkulu ngokwaneleyo, iya kuthi ikhokelele kwingxelo yokubhomboloza. Oko kukuthi, i-karaoke amplifier yamandla kufuneka ikhethe amandla aphezulu kangangoko kunokwenzeka. Nangona kunjalo, ukuphakama kwamandla kwesikhulisi samandla, kokukhona amandla esandi evakala. Ngamava asebenzayo, ijelo ngalinye ngaphakathi kwe-8 Ω 450W linokukhethwa.

Igumbi elingaphantsi kwe-18 yeemitha zesikwere sisiseko esenziwe kakuhle sendalo somculo we-karaoke. Nangona kunjalo, i-echo yesiko iya kubangela ukungaqiniseki kwesiphumo sesandi, kunye nefuthe lokulungisa ingxaki kwindwendwe nganye kunokwenza umphathi angaze akwazi ukumisela isiphumo kwindawo emanyeneyo, eya kuthi nayo idinise uDJ. Isizathu sesibini sokusebenzisa i-amplifier yamandla kunye neprosesa ye-DSP kukuba inkqubo ye-echo yesiphumo sokulungisa inebala elincinci lokuphendula rhoqo (ngaphantsi kwe-8kHz) kunye nokuhamba rhoqo kwesampulu, okwenza ukuba kungabikho zinkcukacha kwimeko efuna amandla aphezulu. Ubungakanani beesampulu ze-DSP ze-48K kunye nobubanzi obubanzi be-20hz-23khz buzisa umgangatho ophucukileyo wesandi kunye namandla aphakathi kunye aphantsi e-dynamics. Kungenxa yoko le nto singenakukwazi ukucula abantu, nje ukuba kusetyenziswe isixhobo sokukhulisa amandla e-DSP, ilizwi labo lenziwe ngesiquphe, linomtsalane ngakumbi, litsala ngakumbi, livakala kamnandi.

Isizathu sesithathu sokusebenzisa i-amplifier yamandla kunye neprosesa ye-DSP kukuba iprosesa yempembelelo ye-DSP inokugcina idatha yeziphumo ezininzi, kwaye inokuzisa isiphumo se- "reverb" esisebenzisekayo, inike abathengi ngakumbi amava e-k, baqonde ngokwenyani inkonzo yokuzenzela yabathengi, kunye nokunciphisa kakhulu iimfuno zenkonzo ye-DJ. Ukongeza, ngokusebenza okuzenzekelayo kwenkqubo yeVOD, isiphumo segumbi labucala sinokufikelela kwinqanaba kwinqanaba elifanayo. Ukulunga, kwigumbi labucala elingaphantsi kwe-18 yeemitha zesikwere, ukuba sivavanya kuphela umgangatho wesandi, isiphumo sendalo esenziwe kakuhle asikho ngaphantsi kwe-DSP, kodwa kubonakala ngathi sityebile kwaye sithambile. I-DSP inencasa yedijithali, engathambanga ngokwaneleyo. Ukuba i-LPF ye-DSP ihlengahlengisiwe yaya kwi-8kHz, uthelekiso phakathi kwezi zinto zombini lucacile. Umahluko ophambili kukwi-frequency frequency amandla, intshisakalo kunye nobukhulu.

Ukukhethwa kwesikhulisi samandla esidlala ikaraoke kunye nokucwangciswa kwangaphambili nangasemva kokuqhekeka ikakhulu kuxhomekeke kwiimfuno zokwenyani zegumbi lesicelo. Kwamagumbi ngaphakathi kwe-18 yeemitha zesikwere, kuyacetyiswa ukuba ukhethe i-DSP edibeneyo yamandla ekaraoke yamandla malunga ne-200W; kumagumbi anendawo engaphezulu kwe-18 yeemitha zesikwere ukuya kuthi ga kwi-25 yeemitha zesikwere, amajelo amathathu ama-200 W DSP amandla okhulisa amandla anokukhethwa ukuba anyuse isithethi esiphakathi njengeziko eliphakathi lesongezelelo selizwi lomntu; Igumbi labucala elinendawo engaphezulu kwe-25 yeemitha zesikwere kufuneka ithathelwe ingqalelo ngokobume begumbi, izinto ezinje ngenqanaba loxinzelelo lwesandi, ukufana kwentsimi yesandi kunye nokusekwa kwakhona kwentsimi kujongwa ikakhulu. Amandla afanelekileyo akhethwe ngokudibanisa iimpawu zesithethi kunye nesikhululo samandla esiphakamileyo samandla esithethi esiphambili. Isikhululo samandla esinezixhobo ezininzi ezinamandla asezantsi sinokusetyenziselwa ukunciphisa iindleko zesithethi esinamandla esincedayo.
