Emhlabeni wobunjiniyela bomsindo, ukuzuza ukukhiqizwa komsindo wekhwalithi ephezulu kubaluleke kakhulu, ikakhulukazi ezindaweni zokusebenza okubukhoma. Elinye lamathuluzi asebenza kahle kakhulu okuthola ikhwalithi yomsindo enhle kakhulu isistimu yomsindo womugqa womugqa. Lobu buchwepheshe bushintshe indlela umsindo osatshalaliswa ngayo ezindaweni ezinkulu, kwakha inkundla yomsindo emangalisayo edonsa ukunaka kwababukeli. Kulesi sihloko, sizohlola ukuthi imishini yomsindo yomugqa womugqa isebenza kanjani, izinzuzo zayo, nokuthi ungawakha kanjani umuzwa womsindo ogxilile.

Ukuqonda Line Array Audio Systems

Amasistimu omsindo afanayo emigqa aqukethe izipikha eziningi ezihlelwe zibheke phezulu. Lo mklamo uvumela ukulawula okuphumelelayo kokusakazwa kwamagagasi omsindo kunezakhiwo zesipikha esivamile. Isihluthulelo ekusebenzeni kahle kwamasistimu omsindo womugqa yikhono lawo lokwakha i-wave front ehambisanayo, ngaleyo ndlela kuncishiswe ukuphazamiseka kwesigaba nokukhulisa ukucaca komsindo.

Lapho uhlu lomugqa lukhiqiza umsindo, izikhulumi ngazinye zisebenza ndawonye ukuze ziveze umsindo ngendlela ethile. Lokhu kulawulwa kokuqondisa kubalulekile ezindaweni ezinkulu, lapho kulula khona ukuthi umsindo udideke futhi uhlanekezelwe. Ngokugxilisa amandla omsindo, uhlu lomugqa lunganikeza ikhwalithi yomsindo engaguquki kumabanga amade, iqinisekise ukuthi ilungu ngalinye lezethameli lithola ukuzizwisa kokusebenza elikuhlosile.

Isayensi ngemuva kokudalwa kwenkundla yomsindo

Umqondo "wesiteji somsindo" ubhekise kokuhlangenwe nakho komsindo okugxilile okugoqa izethameli futhi kuzenze zizizwe sengathi zisemsebenzini. Amasistimu we-line array afinyelela lokhu ngezimiso ezimbalwa ezibalulekile:

1. Lawula Ukwahlukaniswa Kwamazwe

Okunye okugqamile kwemishini yomsindo yohlu lomugqa iphethini yayo yokusabalalisa elawulekayo. Ngokungafani nezipikha ezivamile ezikhipha umsindo kuzo zonke izinhlangothi, amalungu afanayo emigqa aklanywe ngokuyinhloko ukuze akhiqize umsindo endizeni evundlile. Lokhu kusho ukuthi amaza omsindo aqondiswe ngqo ezithamelini, kunokuba abonakale ezindongeni nosilingi, ngaleyo ndlela agweme ukunanela nokukhanselwa kwesigaba.

Ukusabalalisa okulawulwayo kudala inkambu ezwakalayo, egcina ivolumu nokucaca kuhambisana kuyo yonke indawo. Lokhu kubaluleke kakhulu ezinkundleni ezinkulu noma emikhosini yangaphandle, lapho ibanga phakathi kwesiteji nezethameli lingahluka kakhulu.

2. Ingaphambili legagasi elijiyile

Uma izipikha eziningi zisetshenziswa ekucushweni komugqa, zakha i-wavefront ehlangene. Lokhu kusho ukuthi amaza omsindo akhiqizwa isikhulumi ngasinye ahlangana ngendlela ethuthukisa umphumela wawo wonke. Ekugcineni, izethameli zibona umthombo womsindo owodwa, obumbene kuneqoqo lezipikha eziningi, okuholela kumuzwa onamandla kakhulu, ozwakalayo ozwakalayo.

Ikhono lokudala i-wavefront ehlangene liphinde lithuthukiswe ubuchwepheshe obuthuthukisiwe be-digital signal processing (DSP). I-DSP yenza onjiniyela bomsindo bakwazi ukushuna kahle ukusebenza kwesipikha ngasinye kuhlelo, iqinisekise ukuthi basebenza ndawonye ngokuvumelana. Lokhu kunemba kubalulekile ukuze kuzuzwe isiteji somsindo esinamandla ama-array omugqa aziwa ngaso.

3. Ikhono lokudubula ibanga elide

Amasistimu we-line array adizayinelwe izinhlelo zokusebenza zokuphonswa isikhathi eside, okusho ukuthi angakhiqiza umsindo webanga elide ngaphandle kokulahlekelwa ikhwalithi. Lokhu kuzuzisa ngokukhethekile ezindaweni ezinkulu lapho izethameli zisakazeke endaweni ebanzi. Ukuhlelwa okuqondile kwezipikha kuvumela ukuqagela komsindo ogxile kakhulu, okuqinisekisa umsindo ocacile futhi onamandla ngisho nalapho uhlezi kude nesiteji.

Amandla okujikijela isikhathi eside we-array yomugqa nawo anciphisa isidingo samasistimu engeziwe wezipikha, ukugwema ukufaka okwengeziwe kanye nezindleko ezikhulayo. Ngokuthembela kusistimu yomugqa owodwa, onjiniyela bomsindo bangenza izidingo zemishini zibe lula kuyilapho besaletha ikhwalithi yomsindo ehlukile.

Izinzuzo Zemishini Yomsindo Ye-Line Array

Izinzuzo zokusebenzisa isistimu yomsindo womugqa zidlulela ngale kwekhwalithi yomsindo. Nazi ezinye izizathu zokuthi kungani idume ezinhlelweni zokusebenza zokuqinisa umsindo:

1. Ukuqina

Amasistimu we-line array scalable kakhulu futhi afanele imicimbi eminingi, kusukela kumakhonsathi amancane kuya emikhosini emikhulu yomculo. Onjiniyela bomsindo bangangeza noma basuse kalula izipikha ohlwini ngokusekelwe ezidingweni ezithile zendawo ngayinye. Lokhu kuvumelana nezimo kuqinisekisa ukumbozwa komsindo okuphelele ngaphandle kokuphazamisa ikhwalithi yomsindo.

2. Yehlisa izinkinga zempendulo

Impendulo iyinkinga evamile ezindaweni zokuqinisa umsindo obukhoma, ngokuvamile okuholela kumsindo ongemuhle, ophakeme. Idizayini elawulwayo yokusabalalisa yomugqa isiza ukunciphisa izinkinga zempendulo ngokuqondisa umsindo kude kumakrofoni nezinye izisetshenziswa ezibucayi. Lokhu kuvumela abadlali ukuthi bahambe ngokukhululeka esiteji ngaphandle kokwesaba njalo impendulo ephazamisa ukusebenza.

3. Isikhalazo Sobuhle

Ngaphezu kwezinzuzo zobuchwepheshe, amasistimu we-line array nawo anezinzuzo zobuhle. Amalungu afanayo emigqa afaka idizayini eqondile eqondile ehlangana kalula nesilungiselelo sesiteji, okuholela embukisweni obukeka kakhudlwana. Lokhu kubaluleke kakhulu emicimbini lapho inani lokukhiqiza libalulekile.

Ekuphetheni

Amasistimu omsindo afanayo aguqule ubunjiniyela bomsindo obukhoma, adala inkundla yomsindo enamandla engagcini nje ngokuthumba ukunaka kwezithameli kodwa futhi ethuthukisa ukusebenza. Ngokuhlakazeka okulawulwayo, amaza angaphambili agxilile namandla okuqagela ebanga elide, lezi zinhlelo zinganikeza ikhwalithi yomsindo egxilile nemangalisayo. Njengoba ubuchwepheshe buqhubeka buthuthuka, amathuluzi omsindo we-line array ngokungangabazeki azoqhubeka nokuhola indlela emisha yomsindo, iqinisekisa ukuthi izethameli emhlabeni wonke zingajabulela imizwa yomsindo engalibaleki. Kungakhathaliseki ukuthi ihholo lekhonsathi, inkundla yezemidlalo noma ifestivali yomculo yangaphandle, umthelela wamasistimu omsindo womugqa awungabazeki, okuwenza ithuluzi elibalulekile konjiniyela bomsindo nabadlali.
