Momwe mungakhazikitsire amplifier 4-channel? (Njira 3)

18.02.2023 /

Kukhazikitsa 4-channel amplifier kungakhale kovuta. Nazi njira zitatu zomwe zingathetsere chirichonse.

Kukhazikitsa molondola amplifier 4-channel kuli ndi maubwino ambiri. Kumveka bwino kwa mawu, moyo wautali wolankhula komanso kuthetsa kupotoza ndi zina mwa izo. Koma kwa oyamba kumene, kukhazikitsa amplifier kungakhale kosadziwika chifukwa cha zovuta za ndondomekoyi. Kotero, ndikuphunzitsani njira zitatu zosiyana zokhazikitsira amplifier ya 4-channel popanda kuwononga makina omvera a galimoto yanu.

Nthawi zambiri, kuti mukhazikitse amplifier 4-channel, tsatirani njira zitatu izi.

  • Kukhazikitsa pamanja
  • Gwiritsani Ntchito Distortion Detector
  • Gwiritsani ntchito oscilloscope

Werengani njira ina pansipa kuti mumve zambiri.

Njira 1 - Kukhazikitsa pamanja

Njira yosinthira pamanja ikhoza kukhala njira yabwino kwambiri ngati mukufuna kukhazikitsa mwachangu. Kuti muchite izi, mumangofunika screwdriver ya flathead. Ndipo muyenera kuwona zosokoneza pongomvetsera.

Gawo 1 Zimitsani phindu, zosefera ndi zina.

Choyamba, sinthani kuchuluka kwa amplifier kukhala osachepera. Ndipo chitaninso chimodzimodzi kwa zosefera zotsika komanso zapamwamba. Ngati mukugwiritsa ntchito zapadera monga bass boost kapena treble boost, zimitsani.

Onetsetsani kuti mwaletsa zomwe zili pamwambapa pamutu wamutu komanso. Sungani voliyumu ya mutu paziro.

Khwerero 2 - Sinthani ndi kutsitsa voliyumu pamutu wanu

Kenako onjezerani pang'onopang'ono kuchuluka kwa mutu wa mutu ndikuyamba kusewera nyimbo yodziwika bwino. Kwezani voliyumu mpaka mumve kusokonekera. Kenako tembenuzani voliyumu pansi pamlingo umodzi kapena awiri mpaka kupotozako kutatha.

Khwerero 3 - Wonjezerani ndi kuchepetsa phindu la amplifier

Tsopano tengani screwdriver ya flathead ndikupeza mfundo yopindulitsa pa amp. Pang'onopang'ono tembenuzirani mfundoyi molunjika mpaka mutamva kupotoza. Mukamva kupotoza, tembenuzirani mfundo molunjika mpaka mutachotsa kupotoza.

Kumbukirani: Nyimboyi iyenera kuyimba bwino mu masitepe 3 ndi 4.

Khwerero 4. Zimitsani mphamvu ya bass ndikusintha zosefera.

Kenako tembenuzirani knob ya bass kukhala ziro. Kugwira ntchito ndi bass boost kungakhale kovuta. Chifukwa chake khalani kutali ndi bass boost.

Kenako ikani ma frequency omwe mukufuna otsika komanso apamwamba. Ma frequency awa amatha kusiyanasiyana kutengera ma subwoofers ndi ma tweeters omwe amagwiritsidwa ntchito.

Komabe, kuyika sefa yotsika ku 70-80 Hz ndi fyuluta yopita ku 2000 Hz ndizomveka (mtundu wa lamulo la chala chachikulu).

Gawo 5 - Bwerezani

Bwerezani masitepe 2 ndi 3 mpaka mufikire kuchuluka kwa mawu osachepera 80%. Mungafunike kubwereza ndondomekoyi 2 kapena 3 zina.

Amplifier yanu 4 tsopano yakhazikitsidwa molondola.

zofunika: Ngakhale njira yosinthira pamanja ndi yosavuta, ena amatha kukhala ndi vuto lozindikira kusokonekera. Ngati ndi choncho, gwiritsani ntchito njira iliyonse mwa njira ziwirizi.

Njira 2 - Gwiritsani Ntchito Chowunikira Chosokoneza

Chowunikira chosokoneza ndi chida chabwino kwambiri chosinthira amplifier yanjira zinayi. Apa mutha kuphunzira momwe mungagwiritsire ntchito.

Zinthu Zomwe Mudzafunika

  • Distortion detector
  • Zowonongeka

Gawo 1 Zimitsani phindu, zosefera ndi zina.

Choyamba, zimitsani makonda onse, monga momwe zilili mu njira 1.

Gawo 2 - Lumikizani masensa

Chowunikira chosokoneza chimabwera ndi masensa awiri. Alumikizeni ku zotulutsa zoyankhulira za amplifier.

Khwerero 3 - Sinthani Volume ya Mutu Wachigawo

Kenako onjezerani kuchuluka kwa mutu wa mutu. Ndipo nthawi yomweyo, yang'anani ma LED detector detector. Chofiira pamwamba ndi chosokoneza. Choncho, chipangizochi chikazindikira kupotoza kulikonse, kuwala kofiira kudzayatsa.

Panthawiyi, siyani kuwonjezera voliyumu ndi kuchepetsa voliyumu mpaka kuwala kofiira kuzimitsa.

Khwerero 4 - Sinthani Kupindula

Tsatirani njira yomweyo pakukulitsa amplifier monga gawo 3 (onjezani ndi kuchepetsa phindu malinga ndi kupotoza). Gwiritsani ntchito screwdriver kuti musinthe gulu la amplification.

Khwerero 5 - Konzani zosefera

Khazikitsani zosefera zotsika ndi zapamwamba kuti zikhale zolondola. Ndipo zimitsani bass boost.

Gawo 6 - Bwerezani

Bwerezani masitepe 3 ndi 4 mpaka mufikire 80% voliyumu popanda kupotoza.

Njira 3 - Gwiritsani ntchito oscilloscope

Kugwiritsa ntchito oscilloscope ndi njira ina yosinthira amplifier yanjira zinayi. Koma ndondomekoyi ndi yovuta kwambiri.

Zinthu Zomwe Mudzafunika

  • oscilloscope
  • Smartphone yakale
  • Aux-in chingwe cha foni
  • Matani angapo oyesera
  • Zowonongeka

Gawo 1 Zimitsani phindu, zosefera ndi zina.

Choyamba, zimitsani phindu, fyuluta, ndi zina zapadera za amplifier. Chitani chimodzimodzi pa mutu wa mutu. Komanso ikani voliyumu ya mutu wa mutu kukhala ziro.

Khwerero 2 - Letsani okamba onse

Kenako chotsani zokamba zonse kuchokera ku amplifier. Pakukhazikitsa uku, mutha kuwononga mwangozi okamba anu. Chifukwa chake, asungeni olumala.

Gawo 3 - Lumikizani foni yamakono yanu

Kenako, gwirizanitsani foni yamakono yanu kuzinthu zothandizira za mutu wa mutu. Gwiritsani ntchito chingwe choyenera cha Aux-In pa izi. Kenako seweranso kamvekedwe ka mayeso. Pakuchita izi, ndimasankha kamvekedwe ka mayeso a 1000 Hz.

Taonani: Osayiwala kuyatsa mutu wagawo panthawiyi.

Khwerero 4 - Konzani oscilloscope

Oscilloscope yapangidwa kuti iwonetse graph ya chizindikiro chamagetsi. Apa mutha kuwona graph yamagetsi. Koma chifukwa cha izi, choyamba muyenera kukhazikitsa oscilloscope.

Oscilloscope ndi yofanana kwambiri ndi multimeter ya digito. Payenera kukhala zofufuza ziwiri; Chofiira ndi chakuda. Lumikizani chowongolera chofiira ku doko la VΩ ndi chiwongolero chakuda ku doko la COM. Kenako tembenuzirani kuyimba kwa makonda a AC voltage.

Chonde dziwani: Ngati ndi kotheka, sinthani zosefera zotsika ndi zapamwamba musanayambe sitepe 5. Ndipo zimitsani mphamvu ya bass.

Khwerero 5 Lumikizani sensor ku zotulutsa za speaker.

Tsopano gwirizanitsani zofufuza za oscilloscope ku zotulutsa za speaker.

Mu amplifier 4-channel iyi, njira ziwiri zimaperekedwa kwa oyankhula awiri akutsogolo. Ndipo zina ziwirizo ndi za oyankhula akumbuyo. Monga mukuwonera, ndidalumikiza ma probe kunjira imodzi yakutsogolo.

Ma oscilloscopes ambiri amakhala ndi mawonekedwe osasinthika ndi manambala owonetsera (magetsi, apano, ndi kukana). Koma muyenera graph mode. Choncho, tsatirani izi.

Gwirani pansi batani la R kwa masekondi awiri kapena atatu (pansi pa batani la F2).

Sinthani chidwi cha graph ndi batani la F1.

Khwerero 6 - Wonjezerani voliyumu

Pambuyo pake yonjezerani voliyumu ya mutu mpaka pamwamba ndi pansi pa chizindikirocho ndi chathyathyathya (chizindikirochi chimadziwika ngati chizindikiro chodulidwa).

Kenako tsitsani voliyumuyo mpaka mutapeza mawonekedwe omveka bwino.

Umu ndi momwe mungachotsere kupotoza pogwiritsa ntchito oscilloscope.

Khwerero 7 - Sinthani Kupindula

Tsopano mutha kusintha kuchuluka kwa amplifier. Kuti muchite izi, ikani masensa awiri panjira imodzi yakutsogolo monga gawo 6.

Tengani screwdriver ya flathead ndikusintha chiwongolero cha amplifier molunjika. Muyenera kuchita izi mpaka oscilloscope ikuwonetsa chizindikiro chodulidwa. Kenako tembenuzirani mutu molunjika mpaka mutapeza mawonekedwe omveka bwino.

Bwerezani masitepe 6 ndi 7 ngati kuli kofunikira (yesetsani kukwaniritsa voliyumu 80% popanda kupotoza).

Khwerero 8 - Konzani mayendedwe akumbuyo

Tsatirani njira zomwezo monga masitepe 5,6, 7, 4 ndi XNUMX kuti mukhazikitse njira zakumbuyo. Yesani tchanelo chimodzi kuti mupeze tchanelo chakutsogolo ndi chakumbuyo. Amplifier yanu ya XNUMX channel tsopano yakhazikitsidwa ndipo yakonzeka kugwiritsidwa ntchito.

Onani zina mwazolemba zathu pansipa.

  • Momwe mungayatse amplifier popanda waya wakutali
  • Momwe mungakhazikitsire amplifier ndi multimeter
  • Komwe mungalumikizire waya wakutali wa amplifier
