Momwe Mungasankhire Wokamba Nkhani Wabwino wa PA wa Patsamba Lanu

Wokamba nkhani woyenera wa PA wa mafakitale amasankhidwa malinga ndi malo, ntchito ya mawu, ndi zosowa zogwirizanitsa. Ngati malo ali ndi phokoso lalikulu lozungulira, sankhani chitsanzo chokhala ndi malangizo olamulidwa komanso kutulutsa kokwanira kuti mawu asamamveke bwino. Ngati malowo ndi onyowa, fumbi, kapena akunja, perekani chitetezo cha m'chipinda ndi kulimba kwa zinthu. Ngati pulojekitiyi ndi gawo la makina akuluakulu olumikizirana ndi fakitale, onetsetsani kuti ikugwirizana ndi ma amplifiers, ma paging controllers, ma emergency override logic, ndi zofunikira zowunikira.

Ogula nthawi zambiri amaganizira kwambiri mtengo wa mayunitsi, koma chiopsezo cha polojekiti nthawi zambiri chimachokera ku nthawi yogwira ntchito, kukonzanso, komanso kusalandira bwino malo. Pulatifomu yodalirika yolankhulira imachepetsa kuyimba kwautumiki ndikuwonjezera kutsatira malamulo a ogwira ntchito chifukwa mauthenga ndi osavuta kumva ndikuwakhulupirira. Kwa magulu ogula, kuyerekeza kothandiza kwambiri sikungokhala ma watts ndi dB okha, koma ngati mzere wazinthu ungathandizire kulumikizana konse kuyambira paging yachizolowezi mpaka kuyankha kwa ngozi.

Mafunso Ofunsidwa Kawirikawiri Zokhudza Kutumizidwa kwa Okamba Nkhani a Industrial PA mu PA System

1. Kodi cholinga chachikulu cha wokamba nkhani wa mafakitale mu fakitale ndi chiyani?

Cholinga chachikulu ndikulankhula momveka bwino pamalo ogwirira ntchito pomwe pali phokoso, kuti ogwira ntchito athe kumvetsetsa mauthenga achizolowezi komanso adzidzidzi nthawi yomweyo.

2. Kodi ndikufunika ma speaker angati pa makina a PA a fakitale?

Chiwerengerocho chimadalira kukula kwa malo, kuchuluka kwa phokoso, kutalika kwa malo oikira, ndi kuwongolera kwa sipika, kotero yankho lolondola limachokera ku kapangidwe ka mawu osati lamulo lokhazikika.

3. Kodi cholankhulira champhamvu nthawi zonse chimakhala chabwino kwambiri pakupanga mawu m'mafakitale?

Ayi, chifukwa kutulutsa mawu mokweza kungamvekebe ngati malo, kuwala, ndi kukweza mawu molakwika.

4. Ndi miyezo iti yomwe ndiyenera kuyang'ana ndisanayambe kugwiritsa ntchito?
