Emkhakheni wezikhulumi zemultimedia, umqondo we-Independent Power Amplifier okokuqala uvele ngo-2002. Ngemuva kwesikhathi sokutshala kwemakethe, cishe ngo-2005 no-2006, lo mbono omusha we-muldimedia wezikhulumi wemultimedia ubhekwe kabanzi ngabathengi. Abakhiqizi abakhulu besikhulumi baphinde baletha izipikha ezintsha ze-2.1 ngemiklamo yokuphakama yamandla yamandla, ehlele igagasi le- "Independent Power Amplifiers" Ukuthenga kwePanic ". Eqinisweni, eqinisweni, ngokwekhwalithi yomsoco ozwakalayo, ngeke ithuthukiswe kakhulu ngenxa yokwakhiwa kwamandla okusiza amandla azimele. Ama-amplifiers wamandla azimele anganciphisa ngempumelelo umthelela wokuphazanyiswa kwe-electromagnetic ngekhwalithi yomsindo, futhi akwanele ukudala ukuthuthuka okukhulu ngekhwalithi ephezulu. Noma kunjalo, umklamo we-amplifier ozimele wamandla asanele nezinzuzo eziningi ezihlangene ezijwayelekile ze-2.1 multimedia azinayo:

Okokuqala, i-Independent Power Amplifier ayinakho mkhawulo owakhelwe ngaphakathi, ngakho-ke kungafinyelela ukudicilela phansi okungcono kokushisa. Izikhulumi ezijwayelekile ezinama-amplifiers ezakhelwe ngaphakathi zingakwazi kuphela ukuqeda ukushisa nge-insector tube ngoba zivalwe ebhokisini lokhuni elinokuphamba okungekho emthethweni. Ngokuqondene ne-Independent Power Amplifier, yize i-Power Amplifier Circuit nayo ivalwe ebhokisini, ngoba ibhokisi le-amplifier yamandla alifani nesipika, ngakho-ke inani elikhulu lezimbobo zokushisa livulwe esikhundleni sendali yokushisa, ukuze ukushisa kudlule ekuxhumeni kwezemvelo. Hlakaza ngokushesha. Lokhu kubaluleke kakhulu kuma-amplifier aphezulu aphezulu.

Okwesibili, kusuka esicini se-Power Amplifier, i-amplifier ezimele yamandla inenzuzo ukuzuzisa ukuzuza. Kumakhuluma ajwayelekile, ngenxa yezici eziningi ezifana nevolumu nokuqina, ukwakheka kwesifunda kuhlangene kakhulu, futhi kunzima ukufeza isakhiwo seseketheli esilungiselelwe. I-Independent Power Amplifier, ngoba inebhokisi le-amplifier elizimele, linesikhala esanele, ngakho-ke ukwakheka kwesifunda kungaqhubeka kusuka ezidingweni zomklamo kagesi ngaphandle kokuphazanyiswa yizici zenhloso. I-Independent Power Amplifier inenzuzo ekusebenzeni okuzinzile komjikelezo.

Okwesithathu, ngezikhulumi ezinama-amplifiers ezakhelwe ngaphakathi, umoya osebhokisini uhlala udlidliza, kubangela amandla e-PCPBIFIRE we-PCPlifier kanye ne-vibration yama-capacitors nezinye izingxenye zizodlalwa emuva kuzwakala. Ngaphezu kwalokho, isikhulumi sizophinde sibe nemiphumela ye-electromagnetic, noma ngabe isikhulumi sokulwa ngokuphelele se-anti-kazibuthe, kuzoba nokuvuza kobude obungenakugwenywa, ikakhulukazi i-woofer enkulu. Izakhi ze-elekthronikhi ezifana namabhodi wesifunda nama-ics athintwa yi-magnetic flux ukuvuza, okuzophazamisa amanje kusifunda, okuholela ekuphazamiseni umsindo wamanje.

Ngaphezu kwalokho, izikhulumi ezinomklamo ozimele we-Power Amplifier Sebenzisa indlela yokulawula i-Power Amplifier Control, ekhulula kakhulu ukubekwa kwe-subwoofer futhi ilondoloze isikhala sedeskithophu ebalulekile.

Ekhuluma ngezinzuzo zamandla amaningi aunfer ama-polic amplifiers, eqinisweni, angafingqwa emshweni owodwa - uma ungacabangi ngosayizi, intengo, njll.
