2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Nyob zoo txhua tus, hauv kab lus no kuv yuav qhia koj kom tsim koj tus kheej 3 CHANNEL AUDIO MIXER ua ke nrog FM xov tooj cua xa xov

Kauj ruam 1: Taw qhia

Koj puas tau xav txuas koj lub suab lub suab mus rau lub tshuab ua kom nrov nrov, lossis txawm tias muaj koj cov phooj ywg hais lus ib txhij ntawm tib lub tshuab hluav taws xob. Muaj qhov nyuaj ntawm kev tsim cov kab ke zoo li ntawd, thiab hauv kab lus no, peb yuav qhia koj ib qib zuj zus ntawm yuav ua li cas thiaj ua tau 3 CHANNEL AUDIO MIXER koom ua ke nrog FM xov tooj cua xa xov. Qhov uas koj tsis tuaj yeem tsuas yog tham nrog koj cov phooj ywg, tab sis koj yuav muaj ntau tus neeg mloog koj ntawm qhov zaus uas koj tau npaj ua ntej, qhov twg hauv kuv qhov system yog 87.9fm. Koj tuaj yeem saib cov kauj ruam rau kauj ruam yees duab ntawm qhov txuas

Kauj Ruam 2: Thaiv Daim Duab

Hauv kev tsim qauv no, lub tsev thaiv ntawm qhov system tau pom tseeb nthuav tawm siv daim duab thaiv yooj yim, raws li nthuav tawm

Kauj Ruam 3: Lub Suab input input thiab Circuit

ua lub suab tawm tswv yim, txiav txim siab yuav tsum tau ua, thiab rau kuv tus qauv, kuv xaiv siv lub condenser microphone. Qhov hom microphones ua zoo li lub tshuab hluav taws xob tsis zoo li lwm lub microphone uas muaj kev sib txheeb txheeb ze rau lub suab siv los ntawm txhua qhov chaw, yog tib neeg lub suab. Yog tias koj txuas lub condenser mic rau lub kaw lus siv nws sojntsuam (+ve thiab -ve), koj yuav tsis tau txais lub teeb liab tso tawm, koj yuav tsum tau ua kom nws tsim lossis hloov lub suab lub suab mus rau lub teeb liab hluav taws xob, thiab qhov ntawd qhov hloov pauv ntawm txhua qhov hluav taws xob ntawm txhua lub mic yog rau kev tswj hwm, thiab yog vim li cas kuv thiaj siv lub teeb liab rau 3 lub suab tawm tswv yim, thiab LED ntsuab rau qhov qhia.

Kauj ruam 4: CIRCUIT pre-amplifier

Kev teeb tsa ua ntej lub tshuab ua suab nrov los ntawm cov duab saum toj no, siv lub teeb liab los ntawm 3 lub condenser microphone, thiab tom qab ntawd muab nws tso rau lub transistor puag lub teeb liab amplifier. Koj tuaj yeem xaiv ob peb lub microphone teeb liab mus rau lub suab ua ntej, yog tias koj xav ua lub tshuab xa xov tsis txuas nrog lub tshuab sib tov. Qhov kev xaiv no muaj txiaj ntsig, vim nws yuav mus ntev los ua kom tsim qauv yooj yim thiab yooj yim los daws teeb meem. Tab sis yog tias koj xav txuas ntxiv txoj kev txhim kho ib yam li peb tau ua, koj tom qab ntawd tsis txhob ua ob theem ua ntej lub tshuab ua kom nrov nrov, raws li peb tab tom yuav ua kom nrov nrov nrog lawv siv lub tshuab ua haujlwm ua haujlwm, uas peb yuav txuas ntxiv coj cov teeb liab tso rau hauv cov khoom sib tov.

Kauj Ruam 5: OPERATIONAL AMPLIFIER

Cov txheej txheem tov khoom suav nrog op-amp IC nrog ob peb lwm yam sib xyaw ua ke rau nws. Cov duab saum toj no, qhia txog kev teeb tsa raug rau op -amp Hauv qhov teeb tsa no, Kuv teeb tsa lub suab nce mus rau 200 chav siv 10uf electrolytic capacitor ntawm C4. qhov no yooj yim txhais tau tias IC sib tw ua lub teeb liab nkag los ntawm 200 chav. Cia hais tias kuv muaj lub teeb liab los ntawm lub microphone lossis aux cable ua 2 decibels, yog tias lub teeb liab xa mus rau op amp, nws yuav ua kom nrov nrov los ntawm qhov 200, uas yog 400 decibels. Tsis yog qhov loj heev? Kuv txuas C4 nrog qhov sib txawv resistor txhawm rau txhawm rau kho lub suab nce ntawm txhua kis hauv lub sijhawm.

Kauj Ruam 6: MIXER CIRCUIT

Cov duab hauv qab no qhia txog kev sib xyaw ua ke kom tiav. Los ntawm daim duab saum toj no, ntau qhov kev hloov kho tsis tau ua, tsuas yog ob peb qhov sib txawv resistor tau ntxiv thiab ob peb hloov. 3 op-amp nti tau siv raws li peb muaj hauv cov duab hauv qab no.

Kauj Ruam 7: PHYSICAL BOARD

Tom qab OP-AMP channel tau tsim, koj yuav muaj Qhov System zoo li qhov no. Muaj ntau cov lus piav qhia yuav tsis ua ntawm no, vim peb muaj daim duab kos duab los nthuav qhia kev sib txuas. Qhov teeb tsa peb muaj ntawm cov khoom sib txuas hluav taws xob lub tsev sib txawv suab kev tawm tswv yim thiab kev hloov kho kom haum sib xws. Qhov sib xyaw tau teeb tsa los ntawm txhua tus neeg siv, raws li lub suab zoo, ib qho yuav tsum ua raws li Circuit kom raug.

Kauj Ruam 8: HLOOV AUDIO AMPLIFIER

Hoob A AUDIO AMPLIFIER The class A audio amplifier was used as auxiliary amplifier for music, in case one don't want to broadcast. Using a linear adjustable switch, I can always flip to any amplifier (op-amp and class A amplifier) input thiab cov zis.

Kauj Ruam 9: FM Transmitter

Kuv tau sib sau ua ke FM xov tooj cua xa xov module, thiab nthuav tawm Circuit Court.

Kauj Ruam 10: PHYSICAL BOARD

Pawg tswj hwm lub cev ntawm theem no yuav zoo li no.

Kauj Ruam 11: ZOO TSHAJ PLAWS ZOO TSHAJ PLAWS

Txij ntawm no mus, koj yuav txuas tag nrho cov kev sib txuas ua ke raws li qhov kawg ntawm txhua qhov kev faib khoom tau qhia tseg. Txhawm rau kom tau txais daim ntawv PDF ntawm kev txuas txuas, txheeb xyuas qhov txuas hauv qab no.https://m.facebook.com/story.php ? story_fbid = 161398148748024 & id = 102574637963709

Kauj Ruam 12: PACKAGING

Kuv siv lub thawv 6/9 patrex rau ntim, kuv puas tau siv lub qhov tsim nyog rau kev teeb tsa.u

Kauj Ruam 13: TSHUAJ TIV THAIV

Kuv siv cov xim dub thiab grey rau txoj haujlwm txau.

Kauj Ruam 14: QHOV TSEEM CEEB TSHAJ PLAWS RAU INSTALLATION

Txhua lub Cheebtsam tau sib sau ua ke rau kev teeb tsa.

Kauj ruam 15: INSTALLATION

Kuv tau teeb tsa cov khoom siv nrog txhua lwm yam khoom siv hluav taws xob ntawm lub system.

Kauj Ruam 16: Ua tiav TUS TSWV YIM

Tam sim no Cov Txheej Txheem tau npaj rau kev sim !!!

Kauj Ruam 17: TEST

Lub kaw lus tau sim, thiab cov txiaj ntsig tau loj heev.

Kauj Ruam 18: TSEV KAWM NTAWV TSHIAB

Txog tam sim no, tam sim no koj tuaj yeem caw cov phooj ywg los tshaj tawm… Peb tau tshaj tawm thiab ua yeeb yaj kiab nyob uas peb tau tshaj tawm hauv Facebook, peb muaj cov neeg hu tuaj rau peb tshaj tawm thiab qhov ntawd zoo kawg. Txhawm rau saib cov vis dis aus nyem qhov txuas hauv qab no,

Kauj Ruam 19: Koom Nrog Peb Lub Zej Zog

Peb tshaj tawm txoj haujlwm ntawm Kev Siv Hluav Taws Xob, Tshuab Hluav Taws Xob, thiab kev ua haujlwm. Ua raws peb ntawm txhua qhov peb tshaj tawm xov xwm rau kev hloov tshiab, Txuas hauv qab no, Facebook nplooj ntawv https://m.facebook.com/MagnumTechnicalAcademy/YouTube channelhttps://www.youtube.com/channel/ UC3PNnFCNMPbdEHsUdfVJCjAInstagram accounthttps://www.instagram.com/magnum_technical_concept/Telegram accounthttps://t.me/magnumtechnicalconceptTwitterhttps://mobile.twitter.com/MagnusEmenuga
