Mokhoa oa ho theha amplifier ka multimeter

'Mino o matla' me tsamaiso e ntle ea molumo e etsa hore e be betere le ho feta. Fumana molemo ka ho fetisisa ho stereo ea koloi ea hau le tsamaiso ea molumo ka ho lokisa amplifier ea hau hantle ka multimeter. Ha e sireletse lisebelisoa tsa hau feela, empa hape e fana ka boleng bo botle ba molumo.

O ka fetola phaello ea amplifier ea hau ka ho bapisa motlakase oa karolo ea hlooho ea AC le matla a kenyelletso ea amplifier. E boetse e thibela ho fokotsa molumo.

Ho theha taolo ea phaello, o tla hloka tse latelang:

Multimeter ea dijithale, libui, bukana ea amplifier ea hau, sebali, le CD ea matšoao a tlhahlobo kapa flash drive. Mona ke litaelo tsa mohato ka mohato tsa ho lokisa amplifier ka mekhoa e fapaneng.

Mokhoa oa ho theha amplifier ka multimeter?

Mohato oa 1: Lekanya ho se sebetse ha sebui ka multimeter.

Sheba ho se sebetse ha sebui. U tla be u hokahanya le amplifier u sebelisa multimeter ea digital. Ho etsa sena, tima matla ho sebui. Ebe u etsa qeto ea hore na ke terminal efe ea sebui e nepahetseng le e mpe. Hokela tlhahlobo e khubelu ho terminal ebe tlhahlobo e ntšo e lebisa ho terminal e fosahetseng.

Ngola khanyetso ka li-ohm tse bonoang ho multimeter. Hopola hore boholo ba sebui se sitisang ke 2, 4, 8 kapa 16 ohms. Ka hona, boleng bo haufi-ufi ba boleng bo tlalehiloeng bo ka tsejoa ka kholiseho.

Mohato oa 2: Ela hloko matla a khothaletsoang a amplifier.

Nka buka ea mosebelisi ea amplifier 'me u fumane matla a khothaletsoang. Bapisa sena le khanyetso ea sebui sa hau ka li-ohms.

Mohato oa 3: Bala motlakase o hlokahalang oa AC

Hona joale re hloka ho fumana matla a sepheo sa amplifier. Ena ke motlakase o hlahisoang oo re o hlokang ho beha phaello ea amplifier. Ho e bala, re hloka ho sebelisa mofuta o fapaneng oa molao oa Ohm, V = √ (PR), moo V e leng sepheo sa motlakase oa AC, P ke matla, 'me R ke ho hanyetsa (Ω).

Ha re re bukana ea hau e re amplifier e lokela ho ba li-watts tse 500, 'me ho se sebetse ha sebui sa hau, seo u se fumaneng ka multimeter, ke 2 ohms. Ho rarolla equation, atisa li-watts tse 500 ka 2 ohms ho fumana 1000. Joale sebelisa sebali ho fumana "square root" ea 1000 'me motlakase oa hau o tsoang e lokela ho ba 31.62V tabeng ea phetoho ea phaello ea bonngoe.

Haeba u na le amplifier e nang le li-control tse peli tsa phaello, li tla sebetsoa ka boithaopo.

Ka mohlala, haeba amplifier e na le li-watts tse 200 bakeng sa likanale tse 'nè, sebelisa matla a hlahisoang ke mocha o le mong ho bala motlakase. Matla a matla bakeng sa taolo e 'ngoe le e' ngoe ea phaello ke "square root" ea 200 watts x 2 ohms.

Mohato oa 4 Tlosa Lisebelisoa Tsohle

Hakolla lisebelisoa tsohle tse ling, ho kenyeletsoa libui le li-subwoofers, ho tsoa ho amplifier tlas'a teko. Hakolla feela li-terminals tse nepahetseng hore u hopole tlhophiso ha u hloka ho li hokela hape.

Mohato oa 5: Ho beha Equalizer ho Zero

Eka tima se leka-lekaneng kapa u behe litlhophiso tsohle tsa eona joalo ka bophahamo ba modumo, bass, treble, processing, bass boost le mesebetsi e lekanyang ho zero. Sena se thibela maqhubu a molumo hore a se ke a sefshoa 'me ka hona se eketsa boholo ba bandwidth.

Mohato oa 6: Beha Gain to Zero

Bakeng sa li-amplifiers tse ngata, boemo bo fokolang bo fihlelleha ka ho chencha daela ka tsela e fapaneng ho ea moo e tla ea teng.

Mehato ea 4, ea 5 le ea 6 e siea amplifier e hokahane le phepelo ea motlakase feela.

Mohato oa 7: Beha molumo ho 75%

Bulela yuniti ya hlooho ho 75% ya bophahamo ba modumo. Sena se tla thibela melumo e sothehileng ea stereo hore e romelloe ho amplifier.

Mohato oa 8 Bapala Molumo oa Teko

Pele o fetela pele, etsa bonnete ba hore sebui se khaotsoe ho amplifier.

Joale o hloka molumo o llang oa teko ho lekola sistimi ea hau. Bapala lets'oao la liteko ho sistimi ea stereo ka sine wave ho 0 dB. Molumo o lokela ho ba le maqhubu a 50-60 Hz bakeng sa amplifier ea subwoofer le wavelength ea 100 Hz bakeng sa amplifier ea bohareng ba marang-rang. E ka etsoa ka lenaneo le kang Audacity kapa ea khoasolla ho tsoa Marang-rang. (1)

Kenya unit ea hlooho e le hore molumo o bapaloe ka ho tsoelang pele.

Hata 9: Hokela Multimeter ho Amplifier

Beha motlakase oa DMM ho ea ho AC ebe u khetha mofuta o nang le motlakase o lebeletsoeng. Hokela multimeter ho isa likoung tsa tlhahiso ea libui tsa amplifier. Tlhahlobo e ntle ea multimeter e lokela ho behoa sebakeng se setle, 'me probe e mpe ea multimeter e lokela ho behoa sebakeng se fosahetseng. Sena se o nolofalletsa ho lekanya motlakase oa AC ho amplifier.

Haeba motlakase o hlahisoang hang-hang o bontšitsoeng ho multimeter o phahame ho feta 6V, pheta mehato ea 5 le 6.

Mohato oa 10: Fetola Knob ea Gain

Butle-butle fetola knob ea amplifier ha u ntse u shebile palo ea motlakase ho multimeter. Emisa ho lokisa konopo hang ha multimeter e bontša sepheo sa motlakase oa AC oo u o balileng pejana.

Kea u lebohela, u fetotse phaello ka nepo ho amplifier ea hau!

Mohato oa 11: Pheta li-amps tse ling

U sebelisa mokhoa ona, fetola li-amplifiers tsohle tsamaisong ea hau ea 'mino. Sena se tla u fa sephetho seo u neng u se batla - se molemohali.

Mohato oa 12: Beha molumo ho zero.

Fokotsa molumo oa yuniti ea hlooho ho ea ho zero ebe o tima sistimi ea stereo.

Mohato oa 13: Kopanya ntho e 'ngoe le e' ngoe hape

Hokela hape lisebelisoa tsohle joalo ka ha u ka etsa li-amplifiers le libui tse ling; o tlositse pele o kenya phaello. Etsa bonnete ba hore lithapo tsohle li hoketsoe ka nepo 'me u bulele hlooho.

Mohato oa 14: Natefeloa ke 'Mino

Tlosa pina ea teko ho stereo ea hau ebe u bapala e 'ngoe ea lipina tseo u li ratang haholo. Ikakhele ka setotsoana ka 'mino o bohale 'me u natefeloe ke lintho tse sothehileng.

Mekhoa e meng ea ho lokisa amplifier

O ka fetola phaello ea amp ea hau le bass boost ka ho e fetola ka letsoho le ho mamela molumo o monate ka ho fetisisa. Empa mokhoa ona ha o khothalletsoe hobane hangata re hloleha ho tšoara liphoso tse nyane ka ho fetisisa.

fihlela qeto e

Ho sebelisa multimeter ea digital ho fetola phaello ke o mong oa mekhoa e sebetsang ka ho fetisisa le e bonolo ka ho fetisisa. Sena se o nolofalletsa ho beha molemo bakeng sa hoo e batlang e le li-amplifiers tsohle. Tsela e molemohali ea ho thibela ho khopama leha e le efe tsamaisong ea hau ke ho sebelisa oscilloscope. E lemoha ka nepo ho khaola le ho sotha hohle. (2)

Ka multimeter e ntle ka ho fetisisa e teng, re tšepa hore tataiso ena e tla u thusa ho theha amplifier ea hau hantle.

U ka boela ua sheba le ho bala libuka tse ling u sebelisa multimeter e ka u thusang nakong e tlang. Lingoloa tse 'maloa li kenyelletsa: Mokhoa oa ho lekola capacitor ka multimeter le Mokhoa oa ho lekola betri ka multimeter.
