Sisitemu zo Gutanga Aderesi Rusange (PA)bikoreshwa cyane mu nganda, mu mashuri, mu duce tw’ubwikorezi, no mu nyubako z’ubucuruzi mu gutangaza amatangazo, umuziki wo inyuma, no mu itumanaho ryihutirwa.

Mu gushushanya sisitemu ya PA, kimwe mu bibazo bikunze kugaragara ni iki:

Ni irihe tandukaniro riri hagati y'indangururamajwi zifite voltage ihoraho n'indangururamajwi zifite impedance nke?

Ubwo bwoko bwombi bukoreshwa cyane muri sisitemu z'amajwi, ariko bugira akamaro gatandukanye bitewe n'ingano n'ibisabwa mu gushyiraho.

Indangururamajwi za Voltage zihoraho ni iki?

Indangururamajwi zihoraho zikoreshwa cyane murisisitemu nini zo kuvugira mu ruhameIzi sisitemu zisanzwe zikorera kuri70V cyangwa 100V, niyo mpamvu bakunze kwitwaSisitemu z'indangururamajwi za 70V/100V.

Muri sisitemu y'amashanyarazi ahoraho, amplifier itanga ikimenyetso cy'amashanyarazi menshi, kandi buri ndangururamajwi ikubiyemotransformer yubatswemoIyi transformateur yemerera abashyiraho porogaramu guhitamo urwego rw'ingufu zitandukanye nka:

3W

6W

10W

20W

Kubera iyi miterere, indangururamajwi nyinshi zishobora guhuzwamu buryo buteganye ku murongo umwe w'insinga.

Ibyiza bya sisitemu ya Voltage ihoraho

Byoroshye guhuza indangururamajwi nyinshi

Bikwiriye kohereza amajwi mu ntera ndende

Ikwirakwizwa ry'ingufu rihindagurika

Gushushanya no gushyiraho sisitemu byoroshye

Porogaramu zisanzwe

Indangururamajwi zihoraho zikoreshwa cyane muri:

inganda n'inganda

ibibuga by'indege na sitasiyo za gari ya moshi

amashuri n'ibigo by'amashuri

amaduka manini

aho guparika imodoka n'ahantu ho hanze

Ibi bidukikije akenshi bisabaumubare munini w'abavuga rikijyana n'ahantu hanini hakwirakwizwa.

Indangururamajwi zo mu bwoko bwa Low Impedance ni iki?

Indangururamajwi zo hasi zikoresha impedance nke4 ohms cyangwa 8 ohmskandi ugahuza neza na amplifier nta transformer.

Ubusanzwe izi sisitemu zikoreshwa mu bidukikije ahoIreme ry'amajwi ni ryo shingiro ry'ingenzi.

Ibyiza bya sisitemu ntoya zo gukumira impanuka

Ubwiza bw'amajwi bwiza kurushaho

Guhuza amplifier mu buryo butaziguye

Kohereza ingufu neza

Porogaramu zisanzwe

Indangururamajwi zo mu bwoko bwa "low impedance" zikunze gukoreshwa muri:

sisitemu z'amajwi zo mu rugo

ibyumba by'inama

resitora n'utubari

Ahantu ho gucuranga umuziki wa Live

sisitemu z'amajwi n'iz'ikinamico

Ariko, ubusanzwe izi sisitemu zigeneweibikoresho bito bifite indangururamajwi nke.

Voltage ihoraho vs Impedance ntoya: Itandukaniro ry'ingenzi

Ni iyihe sisitemu y'ivugabutumwa ukwiye guhitamo?

Guhitamo hagati y'indangururamajwi zihoraho na indangururamajwi nke biterwa n'ikoreshwa.

Sisitemu z'amashanyarazi zihoraho ni nziza iyo:

ahantu ho gushyiramo ni hanini

hakenewe abavuga benshi

intera ya cable ni ndende cyane

sisitemu ikoreshwa mu gutangaza cyangwa mu muziki ucuranga inyuma

Sisitemu nke za impedance ziba nziza iyo:

Ireme ry'amajwi ni ryo rigomba gushyirwa imbere cyane

hakenewe indangururamajwi nke gusa

ahantu ho gushyiramo ni hato ugereranyije

Umwanzuro

Indangururamajwi zihoraho hamwe n'indangururamajwi nkeya ni ingenzi mu gushushanya sisitemu y'amajwi.

Sisitemu z'amashanyarazi zihorahoni amahitamo asanzwe yo gushyiraho aderesi nini kuko zishyigikira indangururamajwi nyinshi n'intera ndende y'insinga.

Sisitemu nto zo kubuza impedanceKu rundi ruhande, zikwiriye cyane sisitemu nto z'amajwi aho amajwi aba afite ireme ryinshi.

Gusobanukirwa aya tandukaniro bifasha injeniyeri n'abashyiramo porogaramu guhitamo igisubizo cyiza cyane ku mishinga yabo ya sisitemu ya PA.
