Muaj ntau qhov peev txheej hais txog kev tsim cov raj ua ntej ntawm lub vev xaib thiab luam tawm, yog li kuv xav tias kuv yuav qhia qee yam txawv me ntsis. Cov lus qhia no qhia txog kev tsim kho qhov qhib qhov raj preamp ntawm kuv qhov kev tsim thiab tsis tsuas yog qhov kev tsim tshwj xeeb no, tab sis muaj qhov tshwj xeeb hais txog kev nrhiav thiab khaws cov khoom siv hluav taws xob qub rau cov khoom loj tshaj plaws thiab txuag lub zog thaum tsim kho. Cov ntawv qhia no suav nrog cov tshuab nqus tsev nqus hluav taws xob yooj yim thiab suav nrog kev tshuaj xyuas ntawm cov txheej txheem nrog rau kev daws teeb meem siab virtual tsim uas piav qhia tag nrho cov txheej txheem preamp Circuit Court. Qhov kev npaj ua ntej no muaj qee qhov tshwj xeeb tshwj xeeb, thawj lub phaj hluav taws xob rau cov raj tau muab los ntawm SMPS kom tshem tawm cov suab nrov feem ntau tawm ntawm tib neeg lub ntsej muag. Qhov no tseem pab txhim kho kev ua tau zoo ntawm preamp. Qhov thib ob nws muaj lub zog me me tso zis ntu uas zoo ib yam li cov tsheb npav amplifiers pom hauv cov khoom qub sib xyaw thiab kaw cov cuab yeej xws li kaw cov ntawv txiav lossis reel rau reel tshuab. Qhov thib peb qhov kev npaj ua ntej no tsis muaj qhov xaiv tau-lim lossis tswj lub suab, qhov no tso cai rau siab tshaj plaws kom dhau nrog lub suab nrov tsawg. Hloov chaw lub suab tau teeb tsa los ntawm kev xaiv cov khoom sib txuas ua ke thiab lwm yam kev xaiv tsim hluav taws xob. Kuv vam tias qhov kev qhia no muaj txiaj ntsig thiab muab kev nkag siab rau cov pib thiab cov tsim kev paub zoo ib yam.

Kauj Ruam 1: Mloog thiab txiav txim siab yog tias koj xav tsim nws

Qhov kev qhia no yog ntawm Republic Republic tricone resonator guitar kaw nrog PA1 DIY raj preamp thiab qub mxl2001 condenser microphone.

Lub suab thaum pib ntawm daim vis dis aus raug kaw nrog teeb tsa tib yam.

Kuv siv qhov kev npaj ua ntej no rau txhua lub suab-ua haujlwm ntawm txhua qhov ntawm kuv cov vis dis aus.

Kauj Ruam 2: Nrhiav Qhov Project Case

Txhua tus neeg tsim khoom sib txawv, tab sis ntawm no yog daim vis dis aus uas qhia txog yuav ua li cas kom tshem tawm ib qho ntawm cov khoom siv khib.

Kauj Ruam 4: Npaj Cov Txheej Txheem ntawm Kev Tsim Txoj Hauv Kev Uas Txo Cov Nyiaj Txiag Siv

Npaj cov txheej txheem ntawm kev tsim kho hauv txoj hauv kev uas txo qis lub zog uas koj yuav tsum tau haus dej.

Yog tias muaj qhov nyob hauv rooj plaub uas yuav haum rau lub hwj chim thiab lub jacks siv lawv. Koj yuav zoo li yuav tsum tau siv cov txheej txheem xyaum thiab lossis cov ntaub ntawv hlau txhawm rau txhawm rau lub qhov kom txaus kom haum rau lub qhov (socket). Koj kuj tseem yuav tsum tau laum lub qhov rau cov txiv ntoo thiab cov ntsia liaj qhov rooj uas tuav lub raj ntsaws hauv qhov chaw. Sim rov siv lub fuse thiab hloov ntawm lub qub khib mount chav tsev, qhov no txuag qhov chaw, nyiaj txiag thiab lub zog. Tsuas yog lwm qhov uas koj xav tau rau frill yog rau cov dav hlau dav hlau, SMPS board thiab hloov pauv. Rau SMPS lub rooj tsavxwm txiav ib daim yas los tso rau nruab nrab ntawm lub rooj tsavxwm thiab lub cev los ua lub rwb thaiv tsev. Kuv siv lub yas yas dej qab zib yas qub.

Kev npaj yog qhov tseem ceeb kom yooj yim rau txheej txheem sib dhos.

Koj yuav tsum kos tawm qhov twg txhua yam yuav tsum mus hauv theem no.

Yog tias koj tau ntsib nrog CAD software kev tsim kho virtual tuaj yeem pab kom txoj haujlwm mus tau zoo dua.

Txheeb xyuas qhov haum rau txhua qhov thiab xyuas kom muaj chav txaus tsis yog rau qhov khoom nkaus xwb tab sis rau koj txhais tes thiab cov cuab yeej thaum sib dhos.

Kauj Ruam 5: Tsim SMPS Board

Cov txheej txheem sib dhos tau pom nyob hauv cov txheej txheem thiab tsim cov vis dis aus virtual.

Cov vis dis aus saum toj no SMPS yog txhua yam hais txog Taylor SMPS siv hauv txoj haujlwm no.

Kauj Ruam 6: Mount Transformer, Pots, Jacks thiab Terminal Strips

Koj yuav tau txiav txim siab qhov chaw nyob hauv qib 3.

Mount tag nrho cov khoom loj xws li hloov pauv, jacks potentiometer, SMPS board thiab cov davhlau ya nyob twg.

Kauj Ruam 7: Muab Cov Cheeb Tsam tso rau ntawm cov dav hlau dav hlau

Khiav cov khoom tiv thaiv ua los ntawm lub qhov muag ntawm cov davhlau ya nyob twg thiab khoov lawv kom tuav cov khoom nyob hauv qhov chaw.

Kauj Ruam 8: Khiav Cov Hluav Taws Xob Hluav Taws Xob rau Cov Cua Kub ntawm Cov Tub

Peb yuav siv 12 volt DC cua sov kom sib tw tsis tas yuav tsum tau, tab sis tseem pom zoo.

Kauj Ruam 9: Txiav thiab Muab Cov Hluav Taws Xob

Txiav cov xov hlau ib ntawm ib lub sijhawm uas mus los ntawm lub qhov (socket) mus rau cov kab hluav taws xob dav dav. Trim cov rwb thaiv tsev los ntawm ib kawg, pub nws los ntawm lub qhov muag ntawm lub davhlau ya nyob twg sawb thiab ntswj nws nrog cov khoom siv coj los tuav nws hauv qhov chaw ntawm lub davhlau ya nyob twg raug.. Hloov cov xaim mus rau tus pin tseeb ntawm lub qhov (socket) lub raj thiab txiav nws kom ntev.

Khiav cov xov hlau hauv av los ntawm cov kab dav dav mus rau cov ntsiab lus hauv av ib yam nkaus li koj tau siv cov xov hlau los ntawm cov kab dav dav mus rau lub qhov (socket).

Khiav lub teeb liab lub suab los ntawm cov kab hluav taws xob dav hlau thiab cov raj mus rau qhov chaw tsim nyog rau jacks thiab lub zog potentiometer.

Kauj Ruam 10: Txhim Kho Txhua Qhov Kev Sib Txuas

Txheeb ob zaug txhua qhov txhuas mus los ntawm qhov chaw tsim nyog ntawm lub davhlau ya nyob twg mus rau lub ntsiab lus raug ntawm lub jack, lub zog loj lossis lub qhov (socket). Yog tias koj tsis tau paub txog kev siv tshuaj zuam txheeb xyuas qhov vis dis aus no txog kev xaiv cov laug thiab ntws.

Kauj Ruam 11: Ua tiav Kev Txuas Hluav Taws Xob

Ua kom tiav cov xov hluav taws xob thiab ntxiv cov khoom sib txuas rau jacks xws li kab sib chaws xau tiv thaiv ntawm lub qhov nkag.

Triple xyuas txhua qhov kev sib txuas yog nyob hauv qhov chaw raug.

Kauj Ruam 12: Ua raws Diagnostic Checks hauv Virtual Tsim Video

Cov vis dis aus tsim cov npe teev tseg ob peb daim tshev los ua ua ntej txhim kho cov raj lossis ua kom muaj zog ntawm preamp.

Kauj Ruam 13: Txhim Kho Koj Txoj Kev Nkag Siab

Koj tuaj yeem saib cov yeeb yaj kiab tsim 1 kom paub ntau ntxiv txog cov khoom siv hauv cov cuab yeej no.

Tsim cov vis dis aus 2 coj koj mus rau hauv cov phiaj xwm, piav qhia yuav ua li cas Circuit Court ua haujlwm, qee qhov hloov pauv tau, ntxiv rau teeb liab thiab txoj hauv kev.
