Ohlelweni lomsindo, okuvuthayo koPhiko Lomkhulumi kungukuthi ikhanda kakhulu labasebenzisi be-alalelwayo, noma ngabe kusendaweni ye-KTV, noma ibha kanye nesigameko. Imvamisa, umbono ovame kakhulu ukuthi uma umthamo we-amplifier yamandla uvulwe kakhulu, kulula ukusishisa isipika. Eqinisweni, kunezizathu eziningi zokuthi uSomlomo ashise ngaphandle.
1. Ukucushwa okungenangqondo kweizikhulumina-Amandla Amplifiers
Abangani abaningi abadlala umsindo bazocabanga ukuthi amandla okukhipha we-amplifier yamandla amakhulu kakhulu, okuyimbangela yomonakalo ku-tweeter. Eqinisweni, akunjalo. Ezimweni zobungcweti, isipikha singamelana nokushaqeka okukhulu kwesiginali kabili amandla alinganisiwe, futhi singamelana izikhathi ezi-3 ngaso leso sikhathi. I-Peak iqala kabili amandla akalwe ngaphandle kwezinkinga. Ngakho-ke, kuyaqabukela kakhulu ukuthi i-tweeter ishiswe ngamandla aphezulu we-amplifier yamandla, hhayi ngenxa yomthelela onamandla ongalindelekile noma ukukhala kwesikhathi eside kwemakrofoni.
Uchungechunge lwe-AX -Ifektri ye-Pro Audio Amplifier Factory Iziteshi ezi-2 ze-Big Power Power Amplifier
Lapho isinali lingahlanekezwa, amandla anamandla wesiginali esifushane agcwala ngokweqile awela ku-woofer ngamandla aphezulu, angadluli emandleni esifushane sesipika. Ngokuvamile, ngeke kubangele ukuphambuka kwamandla kaSomlomo futhi kulimaze iyunithi yesipika. Ngakho-ke, ngaphansi kwezimo ezijwayelekile zokusetshenziswa, amandla okukhishwa alinganiselwe we-amplifier yamandla kufanele abe yi-1--2 izikhathi zamandla alinganiselwe kaSomlomo, ukuze aqinisekise ukuthi kusetshenziswa amandla lapho amandla kasomlomo.
2. Ukusetshenziswa okungafanele kokuhlukaniswa imvamisa
Ukusetshenziswa okungafanele kwe-Frequency Division Point ye-terminal yokufaka lapho kusetshenziswa ukwahlukaniswa imvamisa yangaphandle, noma ububanzi obujwayelekile bokusebenza kwesipika buyimbangela yokulimala kwe-tweeter. Lapho usebenzisa isihlukanisi esivalekelelayo, i-Frequency Division Point kufanele ikhethwe ngokuqinile ngokuya ngobubanzi bamamvamisa osebenzayo onikezwe ngumenzi. Uma iphuzu le-crossover le-tweeter likhethwe ukuthi liphansi futhi umthwalo wamandla unzima kakhulu, kulula ukushisa i-tweeter.
3. Ukulungiswa okungafanele kwesilinganisi
Ukulungiswa kwesilinganisi nakho kubalulekile. I-Frequency Equalizer isethwe ukunxephezela iziphambeko ezahlukahlukene zensimu yomsindo wangaphakathi namandla angalingani nezikhulumi, futhi kufanele zikhohliswe ngokuhlaziywa kwe-spectrum noma ezinye izinsimbi. Izici zemvamisa yokudlulisela ngemuva kokulungisa iphutha kufanele kube yiflethi elingaphansi kwebanga elithile. Ama-terter amaningi angenalo ulwazi oluzwakalayo enza izinguquko zentando, futhi ngisho nabantu abambalwa baphakamisa imvamisa ephezulu kanye nezindawo ezivame kakhulu zesilinganisi esiphakeme kakhulu, zakha ukwakheka kwe- "v". Uma la mafrikhwensi akhuphuka ngaphezu kwe-10DB uma kuqhathaniswa imvamisa yasemuva (inani lokulungiswa kwesilinganisi livame ukufaka imisindo yomculo, kodwa futhi lingenza kalula ukuthi lesi sigaba sokuhlanekezelwa sivutha kakhulu, lolu hlobo lwesimo luphinde lushiswe khona, lolu hlobo lwesimo luyimbangela enkulu yezikhulumi ezishisiwe.
- Ukulungiswa kwevolumu
Abasebenzisi abaningi babeka i-attenuator ye-post-stage amplifier ku -6DB, -10DB, okungukuthi, ama-70% - 80% we-knob yevolumu, noma isikhundla esijwayelekile, futhi akhuphule okokufaka kwesigaba sokuqala ukuze kufinyelelwe umthamo ofanele. Kucatshangelwa ukuthi isikhulumi siphephile uma kukhona umugqa esikhungweni samandla esikhulisiwe. Eqinisweni, lokhu futhi akukubi. I-Attenuation knobed ye-amplifier yamandla ifaka isiginali yokufaka. Uma okokufaka kwe-amplifier yamandla kufakwa nge-6DB, kusho ukuthi ukulondolozela ivolumu efanayo, isiteji sangaphambili kufanele siphumelwe nge-6DB ngaphezulu, i-voltage yekhanda lokufaka, lizonqunywa ngesigamu. Ngalesi sikhathi, uma kunesiginali enkulu engazelelwe, okuphumayo kuzolayishwa kakhulu i-6DB kusenesikhathi, kuzovela i-waveform ehlanganisiwe. Yize i-amplifier yamandla engalayishwa ngokweqile, okufakwayo kungukuqaqa i-waveform, ingxenye ebabazekayo inzima kakhulu, hhayi kuphela i-treble ehlanekezelwe, kepha i-tweeter ingashisa futhi
When we use the microphone, if the microphone is too close to the speaker or facing the speaker, and the volume of the power amplifier is turned on relatively loudly, it is easy to generate high-frequency sound feedback and cause howling, which will cause the tweeter to burn out. Ngoba iningi lezimpawu zaseMidrange kanye ne-Treble zithunyelwa kusuka kuyunithi ye-Treble ngemuva kokudlula ezahlukaniso zemvamisa, lokhu kudlula okushisa okuthe xaxa, okuqhuma i-coil ephakeme, i-tweeter yephule ngemuva kokwenza i- "Woo" iskere.
Indlela eyiyo ukusebenzisa imakrofoni engasondelene noma ebhekene neyunithi yesipika, futhi umthamo we-amplifier wamandla kufanele andiswe kancane kancane ukusuka kokuncane kuya kokukhulu kuya kokukhulu. Le khasiIsikhalazoUzolinyazwa uma ivolumu iphakeme kakhulu, kepha isimo esingenzeka kakhulu ukuthi amandla esikhulisi se-amplifier angezelele futhi ilawudi le-amplifier elingelona isikhathi esijwayelekile, kepha isibonakaliso nezinye izinto ezinamabala, ezizoshisa isipika.
