Kusistimu yomsindo, ukushiswa kweyunithi yesipika kuyinkinga enkulu kubasebenzisi bomsindo, noma ngabe kusendaweni ye-KTV, noma ibha kanye nesigcawu. Ngokuvamile, umbono ovame kakhulu ukuthi uma ivolumu ye-amplifier yamandla iphendulwa phezulu kakhulu, kulula ukushisa isipika. Eqinisweni, ziningi izizathu ezenza isikhulumi siphele amandla.
1. Ukucushwa okungenangqondo kweizikhulumifuthiizikhulisamandla amandla
Abangane abaningi abadlala umsindo bazocabanga ukuthi amandla okukhipha i-amplifier yamandla makhulu kakhulu, okuyimbangela yomonakalo ku-tweeter. Eqinisweni, akunjalo. Ezikhathini zobungcweti, isipika ngokuvamile singamelana nokushaqeka kwesignali okukhulu kabili kunamandla alinganiselwe, futhi singamelana izikhathi ezi-3 ngokushesha. I-Peak ishaqisa kabili amandla alinganiselwe ngaphandle kwezinkinga. Ngakho-ke, akuvamile kakhulu ukuthi i-tweeter ishiswe ngamandla aphezulu we-amplifier yamandla, hhayi ngenxa yethonya elinamandla elingalindelekile noma ukukhala kwesikhathi eside kombhobho.
Uma isignali ingahlanekezelwe, amandla wamandla esiginali egcwele kakhulu yesikhathi esifushane awela ku-woofer enamandla aphakeme, angeqi ngempela amandla esikhathi esifushane esipikha. Ngokuvamile, ngeke kubangele ukuchezuka kokusatshalaliswa kwamandla kwesipika futhi kulimaze iyunithi yesipika. Ngakho-ke, ngaphansi kwezimo ezivamile zokusetshenziswa, amandla okukhiphayo alinganiselwe we-amplifier yamandla kufanele abe izikhathi ezingu-1--2 amandla alinganiselwe esipika, ukuze kuqinisekiswe ukuthi isikhulisi samandla asibangeli ukuhlanekezela lapho kusetshenziswa amandla esipika.
2. Ukusetshenziswa okungalungile kwe-frequency division
Ukusetshenziswa okungalungile kwephoyinti lokuhlukanisa imvamisa yetheminali yokufaka lapho kusetshenziswa ukwahlukaniswa kwamafrikhwensi angaphandle, noma ububanzi befrikhwensi yokusebenza obungenangqondo yesipika nakho kuyimbangela yomonakalo ku-tweeter. Uma usebenzisa i-frequency divider, iphoyinti lokuhlukanisa imvamisa kufanele likhethwe ngokuqinile ngokuya ngebanga lefrikhwensi yokusebenza yesipika esinikezwe umenzi. Uma iphuzu le-crossover le-tweeter likhethiwe ukuba libe liphansi futhi umthwalo wamandla unzima kakhulu, kulula ukushisa i-tweeter.
3. Ukulungiswa okungalungile kwesilinganisi
Ukulungiswa kwesilinganisi nakho kubalulekile. Isilinganisi sefrequency sisethelwe ukunxephezela ububi obuhlukahlukene benkambu yomsindo wasendlini namafrikhwensi angalingani wezipikha, futhi kufanele kususwe iphutha ngesihlaziyi se-spectrum sangempela noma ezinye izisetshenziswa. Izici zokuvama kokudlulisela ngemva kokulungisa iphutha kufanele zibe ziphansi phakathi kwebanga elithile. Amashuni amaningi angenalo ulwazi oluzwakalayo enza izinguquko ngokuthanda kwakhe, futhi ngisho nabantu abambalwa bakhuphula ifrikhwensi ephezulu nezingxenye zefrikhwensi ephansi yesilinganisi phezulu kakhulu, benze umumo othi "V". Uma la mafrikhwensi anyuswa ngaphezu kuka-10dB uma kuqhathaniswa nemvamisa ye-midrange (inani elilungisiwe lesilinganisi ngokuvamile liyi-12dB), hhayi kuphela ukuhlanekezelwa kwesigaba okubangelwa isilinganisi okuzofaka umbala obala womsindo womculo, kodwa futhi kubangele kalula iyunithi ye-treble yomsindo Ishiswe, lolu hlobo lwesimo luphinde lube yimbangela enkulu yezipikha ezishile.
- Ukulungiswa kwevolumu
Abasebenzisi abaningi bamisa isikhulisi sesikhulisi samandla sangemuva kwesiteji ku--6dB, -10dB, okungukuthi, u-70%--80% weknob yevolumu, noma ngisho nendawo evamile, futhi bakhulise okokufaka kwesiteji sangaphambili ukuze kuzuzwe ivolumu efanelekile. Kucatshangwa ukuthi isikhulumi siphephile uma kukhona umkhawulo kusikhulisamandla. Eqinisweni, nalokhu akulungile. I-attenuation knob yesikhulisi samandla sinciphisa isignali yokokufaka. Uma okokufaka kwe-amplifier yamandla kuncishiswa ngu-6dB, kusho ukuthi ukugcina ivolumu efanayo, isigaba sangaphambili kufanele sikhiphe i-6dB ngaphezulu, i-voltage kufanele iphindwe kabili, futhi i-headroom eguquguqukayo ephezulu yokokufaka, izonqunywa phakathi. Ngalesi sikhathi, uma kukhona isignali enkulu kungazelelwe, okukhiphayo kuzolayishwa ngokweqile ngo-6dB kusenesikhathi, futhi kuzovela i-waveform eqoshiwe. Yize isikhulisi samandla singalayishwanga kakhulu, okokufaka kuyifomethi ye-wave clip, ingxenye ye-treble inzima kakhulu, hhayi i-treble kuphela ehlanekezelwe, kepha i-tweeter nayo ingasha.
Uma sisebenzisa imakrofoni, uma imakrofoni iseduze kakhulu nesipikha noma ibheke esipikheni, futhi ivolumu ye-amplifier yamandla ivulwa ngokuzwakalayo, kulula ukukhiqiza impendulo yomsindo we-high-frequency futhi kubangele ukukhala, okuzokwenza ukuthi i-tweeter iphele. Ngenxa yokuthi amasignali amaningi aphakathi nendawo kanye nama-treble athunyelwa esuka kuyunithi ye-treble ngemva kokudlula isihlukanisi samafrikhwensi, lesi siginali samandla aphezulu sonke sidlula kuyunithi ye-treble enekhoyili ezacile kakhulu, sikhiqize igagasi elikhulu ngokuphazima kweso, okubangela izinga lokushisa eliphezulu ngokuphazima kweso, futhi kuqhume ucingo lwekhoyili yezwi , i-tweeter yaphuka ngemva kokukhala ngokuthi "woo".
Indlela efanele iwukusebenzisa umbhobho ongasondeli noma ungabhekani neyunithi yesipika, futhi umthamo wesikhulisi samandla kufanele ukhuliswe kancane kancane usuka komncane uye omkhulu. Iisipikhaizolimala uma ivolumu iphezulu kakhulu, kodwa isimo esingenzeka kakhulu ukuthi amandla we-amplifier yamandla awanele futhi isipikha sivuliwe kanzima, ukuze ukukhishwa kwe-amplifier yamandla akuyona i-sine wave evamile, kodwa isignali enezinye izingxenye ze-clutter, ezizoshisa isikhulumi.
