Kwihlabathi lobunjineli beaudio, ukufezekisa ukuveliswa kwesandi esikumgangatho ophezulu kubaluleke kakhulu, ngakumbi kwiindawo zokusebenza eziphilayo. Esinye sezona zixhobo zisebenzayo zokufumana umgangatho obalaseleyo wesandi yinkqubo yomsindo yoluhlu. Obu bugcisa butshintshe indlela isandi esisasazwa ngayo kwiindawo ezinkulu, senza indawo yesandi esimangalisayo esithimba ingqalelo yabaphulaphuli. Kweli nqaku, siza kuphonononga ukuba zisebenza njani izixhobo zeaudio zoluhlu, izibonelelo zazo, kunye nendlela yokwenza amava esandi esintywilayo.

Ukuqonda Line Array Audio Systems

Iisistim zesandi zoluhlu lwemigca ziquka izipikha ezininzi ezicwangciswe ngokuthe nkqo. Olu yilo luvumela ulawulo olusebenzayo ngakumbi lokusasazwa kwamaza esandi kunoyilo lwesiqhelo lwesandisi-lizwi. Isitshixo ekusebenzeni kakuhle kweenkqubo zomsindo we-line array kukwazi kwabo ukwenza i-wave wave front ehambelanayo, ngaloo ndlela kuncitshiswe ukuphazamiseka kwesigaba kunye nokwandisa ukucaca kwesandi.

Xa uluhlu lwelayini luvelisa isandi, izithethi zisebenza kunye ukuze zivelise isandi kwicala elithile. Olu lawulo lwesikhokelo lubalulekile kwiindawo ezinkulu, apho kulula ukuba isandi sibe nodaka kwaye sigqwetheke. Ngokugxininisa amandla omsindo, uluhlu lomgca lunokubonelela ngomgangatho ohambelanayo wesandi kwimigama emide, ukuqinisekisa ukuba ilungu ngalinye labaphulaphuli lifumana amava okusebenza ayifunayo.

Inzululwazi emva kokudalwa kwebala elivakalayo

Ingqikelelo ye "soundstage" ibhekisa kumava omsindo antywilayo asonga abaphulaphuli kwaye abenze bazive ngathi bakwintsebenzo. Iisistim zoluhlu lwemigca zifezekisa oku ngemigaqo emininzi engundoqo:

1. Lawula ukunatyiswa kwamagunya

Enye yezona zinto zibalaseleyo zesixhobo somsindo welayini yipatheni yayo elawulekayo yokusasazwa. Ngokungafaniyo nezithethi zemveli ezikhupha isandi kuwo onke amacala, uluhlu lwemigca luyilwe ngokuyintloko ukwenza isandi kwinqwelomoya ethe tye. Oku kuthetha ukuba amaza omsindo ajoliswe ngqo kubaphulaphuli, kunokuba abonise ngaphandle kweendonga kunye neesilingi, ngaloo ndlela enqanda i-echoes kunye nokurhoxiswa kwesigaba.

Ukusasazwa okulawulwayo kudala indawo enesandi esithe chatha, ukugcina umthamo kunye nokucaca kuhambelana kuyo yonke indawo. Oku kubaluleke kakhulu kwiinkundla ezinkulu okanye kwimikhosi yangaphandle, apho umgama phakathi kweqonga kunye nabaphulaphuli unokuhluka kakhulu.

2. Umphambili wamaza ojinisiweyo

Xa izithethi ezininzi zisetyenziswa kuqwalaselo loluhlu lomgca, zenza umphambili wamaza odibeneyo. Oku kuthetha ukuba amaza esandi akhutshwa sisithethi ngasinye ayadibana ngendlela eya kwandisa umphumo wawo. Ekugqibeleni, abaphulaphuli babona umthombo wesandi omnye, odibeneyo endaweni yengqokelela yezithethi ezininzi, okukhokelela kumava anamandla ngakumbi, antywilayo.

Ukukwazi ukwenza i-wavefront edibeneyo yongezwa ngakumbi ngeteknoloji ye-digital signal processing (DSP) . I-DSP yenza ukuba iinjineli zesandi zilungelelanise kakuhle ukusebenza kwesithethi ngasinye kuluhlu, ziqinisekisa ukuba zisebenza kunye ngemvisiswano. Oku kuchanekileyo kubalulekile ekufezekiseni inqanaba lesandi elinamandla elaziwa ngalo uluhlu lwemigca.

3. Isakhono sokudubula kuluhlu olude

Iisistim zoluhlu lwemigca ziyilelwe usetyenziso oluphoswayo ixesha elide, okuthetha ukuba banokuvelisa isandi esivakalayo ngaphandle kokuphulukana nomgangatho. Oku kuyingenelo ngokukhethekileyo kwiindawo ezinkulu apho abaphulaphuli besasazeke kwindawo ebanzi. Ulungelelwaniso oluthe nkqo lwezithethi luvumela isandi esigxininise ngakumbi, siqinisekisa isandi esicacileyo nesinamandla naxa sihleli kude neqonga.

Ikhono lokuphosa ixesha elide loluhlu lomgca lunciphisa imfuno yeenkqubo ezongezelelweyo zesithethi, ukuphepha ukufakwa okongeziweyo kunye neendleko ezongezelelweyo. Ngokuthembela kuluhlu lwenkqubo yoluhlu olunye, iinjineli zesandi zinokwenza lula iimfuno zesixhobo ngelixa zisazisa umgangatho wesandi obalaseleyo.

Izinto eziluncedo zeLine Array Audio Equipment

Iinzuzo zokusebenzisa inkqubo yomsindo yoluhlu lwandiswe ngaphaya komgangatho wesandi. Nazi ezinye izizathu zokuba kutheni idumile kwizicelo zokuqinisa isandi:

1. Ukubaleka

Iinkqubo ze-line array scalable kakhulu kwaye zifanelekile kwiziganeko ezininzi, ukusuka kwiikonsathi ezincinci ukuya kwimikhosi emikhulu yomculo. Iinjineli zesandi zinokongeza okanye zisuse ngokulula izithethi kuluhlu ngokusekwe kwiimfuno ezithile zendawo nganye. Oku bhetyebhetye kuqinisekisa ukugqunywa kwesandi esifanelekileyo ngaphandle kokubeka esichengeni umgangatho wesandi.

2. Nciphisa imiba yengxelo

Impendulo yingxaki eqhelekileyo kwiindawo zokuqinisa isandi esiphilayo, esihlala sikhokelela kwingxolo engathandekiyo, ephezulu. Uyilo olulawulwayo lokusasazwa koluhlu lomgca lunceda ukunciphisa iingxaki zempendulo ngokusalathisa isandi kude ne-microphone kunye nezinye izixhobo ezinovakalelo. Oku kuvumela abadlali ukuba bahambe ngokukhululekileyo kwiqonga ngaphandle koloyiko oluqhubekayo lwempendulo ephazamisa ukusebenza.

3. Isibheno sobuhle

Ukongeza kwiinzuzo zobugcisa, iinkqubo zomgca wemigca nazo zineenzuzo zobuhle. Uluhlu lwemigca lubonisa uyilo oluthe tye oluthe nkqo oludibanisa ngokungenamthungo kunye nokuhlelwa kweqonga, okukhokelela kumboniso obonakalayo obonakalayo. Oku kubaluleke kakhulu kwiziganeko apho ixabiso lemveliso jikelele libalulekile.

ukuququmbela

Iisistim zoluhlu lwezandi zoluhlu ziguqule ubunjineli besandi esiphilayo, zenza ibala lesandi elinamandla elingathathi kuphela ingqalelo yabaphulaphuli kodwa likwaphucula ukusebenza. Ngokusasazwa okulawulwayo, amaza angaphambili agxininisiweyo kunye nobuchule bokuqikelela umgama omde, ezi nkqubo zinokubonelela ngomgangatho wesandi ontywilayo kunye omangalisayo. Njengoko itekhnoloji iqhubeka nokuphuhliswa, izixhobo zesandi zomgca ngokungathandabuzekiyo ziya kuqhubeka zikhokelela kwindlela entsha yokuvelisa isandi, ukuqinisekisa ukuba abaphulaphuli kwihlabathi liphela banokonwabela amava esandi angalibalekiyo. Ingaba iholo yekonsathi, ibala lezemidlalo okanye umnyhadala womculo wangaphandle, impembelelo yeenkqubo zomsindo we-line array ayithandabuzeki, iyenza ibe sisixhobo esiyimfuneko kwiinjineli zesandi kunye nabadlali.
