Muri sisitemu y'amajwi, gutwika indangururamajwi ni ikibazo gikomeye ku bakoresha amajwi, haba ahantu ha KTV, cyangwa ahantu hagaragara. Akenshi, igitekerezo gikunze kugaragara ni uko iyo ingano y'ingufu z'amashanyarazi irenze urugero, biroroshye gutwika indangururamajwi. Mu by'ukuri, hari impamvu nyinshi zituma indangururamajwi zishira.
1. Imiterere idahwitse yaabavuganaamplifier z'amashanyarazi
Inshuti nyinshi zicuranga amajwi zitekereza ko imbaraga zisohoka za amplifier y'amashanyarazi ari nini cyane, ari nabyo byangiza tweeter. Mu by'ukuri, si byo. Mu bihe by'umwuga, indangururamajwi muri rusange ishobora kwihanganira guhungabana gukomeye kw'amajwi inshuro ebyiri z'imbaraga zisanzwe, kandi ishobora kwihanganira inshuro 3 ako kanya. Guhungabana gukomeye gukabije inshuro ebyiri z'imbaraga zisanzwe nta kibazo. Kubwibyo, ni gake cyane ko tweeter itwikwa n'imbaraga nyinshi za amplifier y'amashanyarazi, atari ukubera ingaruka zikomeye zitunguranye cyangwa urusaku rw'igihe kirekire rwa mikoro.
Iyo ikimenyetso kidahinduwe, ingufu z'ingufu z'ikimenyetso cy'igihe gito cyuzuye zigwa kuri woofer ifite imbaraga nyinshi, zitarenze imbaraga z'igihe gito z'ikimenyetso. Muri rusange, ntabwo bizatera guhindagurika kw'ikwirakwizwa ry'ingufu z'ikimenyetso no kwangiza igice cy'ikimenyetso. Kubwibyo, mu mikoreshereze isanzwe, imbaraga z'ingufu z'ikimenyetso cy'ingufu zigomba kuba inshuro 1-2 z'ingufu z'ikimenyetso cy'ingufu, kugira ngo hamenyekane ko amplifier y'ingufu idahindura ingufu iyo imbaraga z'ikimenyetso cy'ingufu zikoreshejwe.
2. Gukoresha nabi igabanywa ry'inshuro
Gukoresha nabi aho umurongo ugabanya inshuro z'umuvuduko w'icyuma gitanga amakuru iyo hakoreshejwe umurongo ugabanya inshuro z'umuvuduko wo hanze, cyangwa aho umurongo ugabanya inshuro z'umuvuduko w ...
3. Guhindura nabi icyuma gipima ingano
Guhindura equalizer nabyo ni ingenzi cyane. Equalizer ya frequence igenewe kwishyura inenge zitandukanye z'amajwi yo mu nzu n'imivugire idahuye y'indangururamajwi, kandi igomba gukosorwa hakoreshejwe icyuma gipima spectrum cyangwa ibindi bikoresho. Imiterere y'impinduka zo kohereza amajwi nyuma yo gukosora amajwi igomba kuba iringaniye mu rugero runaka. Abatuner benshi badafite ubumenyi bw'amajwi bakora impinduka uko bishakiye, ndetse n'abantu benshi bazamura frequence yo hejuru n'imivugire mike y'indangururamajwi hejuru cyane, bigatuma habaho ishusho ya "V". Iyo iyi frequences yongereweho 10dB ugereranije n'imivugire yo hagati (ingano y'impinduka muri equalizer muri rusange ni 12dB), si ukugoreka gusa kwa phase guterwa na equalizer bizahindura cyane ijwi ry'umuziki, ahubwo binatera treble unit y'amajwi. Burned out, ubu bwoko bw'ibintu ni nabyo bitera indangururamajwi zaburiye.
- Guhindura ijwi
Abakoresha benshi bashyira attenuator ya amplifier y'amashanyarazi nyuma y'urwego kuri -6dB, -10dB, ni ukuvuga 70%--80% by'akabuto k'ijwi, cyangwa se ahantu hasanzwe, hanyuma bongera ubwinjiriro bw'urwego rw'imbere kugira ngo bagere ku ijwi rikwiye. Bikekwa ko indangururamajwi ari nziza niba hari agace gato muri amplifier y'amashanyarazi. Mu by'ukuri, ibi nabyo si byo. Akabuto k'ingufu ka amplifier y'amashanyarazi kagabanya ikimenyetso cy'ubwinjiriro. Niba ubwinjiriro bw'amplifier y'amashanyarazi bwagabanutseho 6dB, bivuze ko kugira ngo ingano ikomeze kuba imwe, urwego rw'imbere rugomba kongera 6dB, voltage igomba gukuba kabiri, kandi headroom yo hejuru y'ubwinjiriro, izacibwamo kabiri. Muri iki gihe, niba habayeho ikimenyetso kinini gitunguranye, umusaruro uzarengerwa 6dB hakiri kare, kandi hakagaragara waveform yaciwe. Nubwo amplifier y'amashanyarazi idaremerewe cyane, input ni clipping waveform, igice cya treble kiraremereye cyane, si treble gusa ihindagurika, ahubwo na tweeter ishobora no gushya.
Imbonankubone-2.18B Amplifier nini y'ingufu kuri Subwoofer--Umutanga Amplifier Pro
Iyo dukoresheje mikoro, iyo mikoro yegereye cyane indangururamajwi cyangwa ireba indangururamajwi, kandi ingano y'imashini itera imbaraga ikaba yafunguye cyane, biroroshye gutanga amajwi menshi kandi bigatera urusaku, ibyo bigatuma tweeter isha. Kubera ko ibimenyetso byinshi byo hagati na treble byoherezwa bivuye kuri treble unit nyuma yo kunyura mu gice gitandukanya frequence, iki kimenyetso gifite ingufu nyinshi kinyura muri treble unit gifite coil nto cyane, kikabyara umuyoboro munini w'amashanyarazi uhita utera, bigatera ubushyuhe bwinshi ako kanya, kandi kikavuza insinga y'ijwi, tweeter yacitse nyuma yo gutaka "woo".
Uburyo bwiza ni ugukoresha mikoro itari hafi cyangwa ngo yerekeze ku gice cy'indangururamajwi, kandi ubushobozi bwo kongera ingufu bugomba kwiyongera buhoro buhoro kuva ku ntoya kugera ku nini.indangururamajwibizangirika niba ijwi riri hejuru cyane, ariko birashoboka cyane ko imbaraga za amplifier y'amashanyarazi zidahagije kandi indangururamajwi ikaranze cyane, ku buryo umusaruro wa amplifier y'amashanyarazi utaba umuraba usanzwe, ahubwo ari ikimenyetso kirimo ibindi bice by'akajagari, bizatwika indangururamajwi.
