Kwinkalo yobunjineli bomsindo, ukusukelaisandi esikumgangatho ophezuluiqhube uphuhliso oluqhubekayo lwetekhnoloji yezixhobo zomsindo ezahlukeneyo. Phakathi kwazo, iisistim zoluhlu lwemigca ziye zaba sisisombululo soguqulo lokufumana umgangatho obalaseleyo wesandi, ngakumbi kwiindawo ezinkulu. Eli nqaku liphonononga indlela iisistim zomsindo we-line array zingadala amava esandi esintywilayo, eqinisekisa ukuba yonke ikona yendawo izaliswe ziziphumo zomsindo ezothusayo.
Ukuqonda Line Array Audio Systems
Isixokelelwano soluhlu lwesandi sinezipikha ezininzi ezicwangciswe ngokuthe nkqo. Olu lungelelwaniso luvumela ulawulo olungcono lokusasazwa kwamaza esandi kunobumbeko besandisi-lizwi esiqhelekileyo. Uyilo loluhlu lwemigca luyenza ikwazi ukwenza isandi kwimigama emide ngelixa igcina ukucaca kunye nokungaguquguquki. Oku kuluncedo ngakumbi kwiiholo ezinkulu, iiholo zekonsathi, kunye nemisitho yangaphandle apho isandi sifuna ukufikelela kuwo onke amalungu abaphulaphuli ngokulinganayo.
Isitshixo ekusebenzeni kweenkqubo zomgca woluhlu kukukwazi kwabo ukulawula ukusasazwa kwesandi. Ukusebenzisa iteknoloji ephakamileyo, ezi nkqubo zinokujolisa amandla omsindo kwicala elithile, ukunciphisa ukubonakaliswa kunye ne-echoes ezinokuchaphazela umgangatho wesandi. Olu lawulo lwe-directivity luqinisekisa ukuba isandi sifikelela kubaphulaphuli ngokuchaneka kwe-pin, ukudala amava okuntywila ngokuqinisekileyo okukuntywilisela.
Isandi esintywilayo ngetekhnoloji yoluhlu lomgca
Enye yeenzuzo eziphawulekayo zeenkqubo zesandi zomgca woluhlu kukukwazi ukubonelela ngesandi esintywilayo. Nokuba yikonsathi ephilayo, umdlalo weqonga okanye umsitho weshishini,umgangatho wesandiibaluleke kakhulu. Uluhlu lwemigca luyagqwesa kule ndawo, lubonelela ngolungelelwaniso, imveliso yeaudio eguqukayo eyandisa i-ambience iyonke.
1. Ukuhanjiswa kwesandi esifanayo: Iisistim zoluhlu lwemigca ziyilelwe ukubonelela ngesandi esifanayo kwindawo ebanzi. Oku kuthetha ukuba kungakhathaliseki ukuba abaphulaphuli bahlala phi, baya kufumana isandi esikumgangatho ophezulu ofanayo. Oku kufana kubalulekile ekudaleni imeko-bume yokuntywila kuba iqinisekisa iziphumo zesandi ezingaguqukiyo nokuba uphi na.
2. Ukucaca okuphuculweyo kunye neenkcukacha:Iinkqubo zoluhlu lwemigcasebenzisa ubuchwephesha bobunjineli obuphambili ukuphumeza ukuzala kwesandi esicacileyo, esityebileyo. Oku kubaluleke ngakumbi kwizandi ezichuliweyo, njengokurhashaza kwamagqabi okanye ukuduma kwendudumo. Iisistim zoluhlu lwemigca zinokugcina ezi nkcukacha, zivumela abaphulaphuli ukuba bangene ngokupheleleyo ekusebenzeni.
3. Uluhlu lweDynamic: Iisistim zoluhlu lwemigca ziyakwazi ukuphatha uluhlu olubanzi oluguquguqukayo, oku kuthetha ukuba banokuphinda bavelise ngokugqibeleleyo zombini izandi ezithambileyo nezikhwazayo ngaphandle kokuphazamiseka. Obu buchule bubalulekile ekudaleni izandi ezinamandla ezihambelana nabaphulaphuli. Ngokomzekelo, ukuqhuma ngokukhawuleza kwe-cannon kwintsebenzo yethiyetha okanye ukusebeza okuthambileyo komlinganiswa kunokubonakaliswa ngokuchaneka okulinganayo, ukuphucula impembelelo yemvakalelo yokusebenza.
4. Nciphisa ingxelo kunye nokuphazamiseka: Omnye wemingeni yokuqinisa isandi esiphilayo kukulawula ingxelo kunye nokuphazamiseka. Iisistim zoluhlu lwemigca ziyilelwe ukunciphisa le miba, okukhokelela kwisandi esicacileyo. Oku kubaluleke kakhulu kwiindawo apho kusetyenziswa ii-microphone ezininzi, njengoko kuqinisekisa ukuba imiphumo yesandi idityaniswe ngaphandle komthungo kwaye igweme ingxolo engadingekile.
Indima yezixhobo zeaudio kwiinkqubo zoluhlu lwemigca
Ukufezekisa ezona ziphumo zibalaseleyo ukusuka kwisixokelelwano soluhlu lwesandi, umgangatho wesixhobo somsindo esisetyenzisiweyo ubalulekile. I-amplifiers ezikumgangatho ophezulu,abaxubi, kunye neeyunithi zokusetyenzwa zisebenza ngokubambisana nezithethi zoluhlu lwemigca ukwenza amava omsindo angenamthungo. Nanga amanye amalungu aphambili achaphazela umgangatho wesandi ngokubanzi:
-Izandisi zamandla: Zinamandlaizikhulisa-zwizibalulekile kwiinkqubo zoluhlu lokuqhuba. Banikezela ngamandla ayimfuneko ukuqinisekisa ukuba isandi siphuma kwivolumu efunekayo ngaphandle kokuphazamiseka. I-amplifier efanelekileyo inokwandisa uluhlu oluguquguqukayo kunye nokucaca kwesandi, okwenza kube nefuthe ngakumbi.
-Umxube: Umxube okumgangatho ophezulu unika injineli yesandi ukulawula amanqanaba omsindo, i-EQ, kunye neziphumo ezisetyenziswa kumthombo ngamnye wesandi. Olu lawulo luyimfuneko ekulinganiseni izinto ezahlukeneyo zokusebenza, ukuqinisekisa ukuba iziphumo zesandi zihamba kakuhle kumxube wonke.
- I-Digital Signal Processor (DSP): Ii-DSPs zidlala indima ebalulekileyo ekuphuculeni umgangatho wesandi. Zingasetyenziselwa ukulungelelanisa ukuphendulwa rhoqo kweesistim ze-line array, ukuhlawulela i-acoustics yegumbi, kunye nokusebenzisa iziphumo eziphucula amava okuphulaphula. Ngokulungisa kakuhle imveliso yeaudiyo, ii-DSP zinceda ekudaleni indawo entywilayo ngakumbi.
ukuququmbela
Lilonke, iisistim zeaudio zoluhlu lwelayini zibonisa ukuqhubela phambili okubonakalayo kwitekhnoloji yomsindo, ukubonelela ngomgangatho wesandi ongenakulinganiswa kunye nesandi esintywilayo. Ukusasazwa kwayo okuvakalayo, ukucaca okuphuculweyo kunye noluhlu oluguquguqukayo luyenza ibe lolona khetho lufanelekileyo lweendawo ezinkulu kunye nemisitho. Idityaniswe nezixhobo zomsindo ezikumgangatho ophezulu, imigca yoluhlu inokuguqula nayiphi na indawo ibe yindawo emangalisayo yokuva, iqinisekisa ukuba yonke ikona izaliswe ziziphumo zomsindo ezothusayo ezitsala kwaye zibandakanye abaphulaphuli. Njengoko imfuno yomsindo wekhwalithi ephezulu iqhubeka ikhula, iinkqubo zomgca womgca ngokungathandabuzekiyo ziya kudlala indima ephambili ekubumbeni amava omsindo wexesha elizayo.
