Qhov kev txiav txim ntawm kev txuas cov teebmeem thiab daim duab ntawm ib qho yooj yim pedalboard

Thaum kawg peb tau txais cov teebmeem guitar, nws yog lub sijhawm los ntsaws rau hauv. Tsis muaj teeb meem nrog ib qho teebmeem, tab sis thaum peb twb muaj ob peb ntawm lawv, lawv yuav suab txawv nyob ntawm qhov kev txiav txim uas lawv txuas. Kuv tseem yuav qhia rau koj qee cov lus tseem ceeb thiab txawm tias ib qho lus ceeb toom, uas kuv yuav pib.

Powering cov teebmeem los ntawm lub mains

Lub pedalboard feem ntau yog siv los ntawm ib qho chaw sab nraud, tsuas yog los ntawm lub qhov hluav taws xob. Yuav tsis muaj teeb meem yog tias nws tsis yog rau qhov tseeb tias cov tuam ntxhab sib txawv siv cov polarity sib txawv. Peb yuav tsis delve rau hauv nws los ntawm scientific point of view, vim hais tias qhov no tsis yog dab tsi yog hais txog. Nws yog txaus los siv ib txoj cai. Yog hais tias cov nyhuv muaj ib tug ntxiv nyob rau hauv nruab nrab, txuas mus rau lub hwj chim mov uas kuj muaj ib tug ntxiv nyob rau hauv nruab nrab. Yog hais tias cov nyhuv muaj ib tug minus nyob rau hauv nruab nrab, txuas mus rau lub hwj chim mov uas kuj muaj ib tug rho tawm nyob rau hauv nruab nrab. Txwv tsis pub koj tuaj yeem pin cov nyhuv tsis raug txuas nrog. Thaum xaiv lub pedalboard fais fab mov, nws yog qhov zoo tshaj plaws los xaiv ib qho uas muaj ib ceg rau hauv ob ntu vim qhov polarity. Lwm txoj hauv kev tsuas yog siv cov teebmeem nrog ib qho polarity, ob lub zog sib txawv, lossis kom muaj zog tag nrho cov teebmeem ntawm cov roj teeb nkaus xwb. Tag nrho cov txheej txheem no yog, muab nws me me, tedious.

Cov teebmeem voj

Ua ntej sim ua kom tiav lub pedalboard, xyuas kom meej tias peb lub amplifier muaj cov teebmeem loops (FX LOOP). Yog tsis muaj loops, koj tuaj yeem ua tiav kev siv sab nraud distortion, compressor thiab wah-wah. Cov kev cuam tshuam no yuav tsum tsis txhob txuas nrog nws. Nws yog qhov zoo dua los txuas cov teebmeem ntxiv rau lub voj. Qhov no yog, ntawm chav kawm, tsis tsim nyog heev, tab sis tom qab tag nrho, cov teebmeem voj voog nyob rau hauv high-class amplifiers tsis yog rau kho kom zoo nkauj, tab sis muaj ib tug tseem ceeb muaj nuj nqi.

Boosting lub amplifier

Qhov no kuj yog ib lub ncauj lus hais txog cov teebmeem. Feem ntau nws siv lub teeb los yog nruab nrab overdrive los yog distortion hom distortion thiab lub built-in distortion channel hauv amplifier. Nws yog qhov zoo tshaj plaws los hlawv cov tube-raws li amplifiers, vim hais tias lawv cov built-in distortion nyiam lub thiaj li hu ua tube amplifiers vim lawv cov yam ntxwv raj. txawm tias harmonics. Lub suab nrov hauv lub voos xwmfab qhia txog qhov txawv ntawm kev sib haum xeeb nrog rau qhov sib txawv ua rau hauv cov amplifiers raws li cov transistors. Tsuas yog qhov sib xyaw ua ke thiab khib nyiab tau ntxiv nrog cov yam ntxwv tom qab hlawv. Qhov no yuav ua li cas? Nyob rau tib lub sij hawm, lub distortion channel thiab sab nraud distortion koom. Nws pib nrog qhov "tau txais" ntawm xoom. Ob qho "tau txais" maj mam nce mus txog thaum muaj kev cuam tshuam txaus siab ua tiav. Koj tuaj yeem sim, nres ob qho "tau txais" ntawm ib qho chaw nyab xeeb thiab maj mam tsa tsuas yog ib qho ntawm lawv, lwm yam tsis tsiv. Koj yuav tsum tsis txhob siv ob qho tib si distortions puv!

Muaj Tseeb

Nws yog qhov zoo tshaj los nrhiav cov teebmeem nrog True Bypass thev naus laus zis. Ua tsaug rau nws, cov nyhuv hloov pauv tsis cuam tshuam rau lub teeb liab uas ntws los ntawm nws. Qhov no yog qhov tseem ceeb tshwj xeeb nrog lub voj voog ntev ntev, thaum peb muaj ob peb qhov hloov pauv thiab ntau qhov kev hloov pauv ntawm cov teebmeem txuas rau hauv lub tshuab hluav taws xob tib lub sijhawm, vim tias cov teebmeem tsis muaj cov thev naus laus zis no, txawm tias lawv tau hloov pauv, xim lub suab.

Kev txiav txim

Cia peb mus rau qhov kev txiav txim ntawm cov teebmeem. Peb paub qhov txawv ntawm ob "chains". Ib qho ntawm lub guitar thiab lub amp lub ntsiab lus tswv yim, lwm qhov ntawm cov teebmeem voj xa thiab cov teebmeem voj rov qab. Ua ntej txuas cov ntxaij lim dej rau thawj cov saw hlau. Nws suab tsis meej, tab sis cov lim feem ntau yog wah-wah, yog li txhua yam yog qhov tseeb. Tom qab ntawd peb muaj compressor, yog tias peb muaj ib qho. Qhov no yog qhov laj thawj vim tias tom qab lim nws compresses lub teeb liab ua ntej ua ntej rau kev txiav txuas ntxiv. Tom ntej no peb muaj teeb liab clipping teebmeem. Qhov ntawd txhais li cas clipping? Koj tuaj yeem siv lwm lo lus nrov dua - distortion. Thiab txhua yam yog tseeb dua. Tag nrho cov overdrive, distortion thiab fuzz cuam tshuam ntawm no.

Tej zaum yuav muaj qee lub sijhawm thaum qee qhov cuam tshuam cuam tshuam tsis ua haujlwm nrog cov os ntawm qhov no. Tom qab ntawd peb ntsaws lawv ua ntej wah-wah. Tau kawg, peb tuaj yeem txuas rau cov teebmeem cuam tshuam uas suab zoo tom qab os. Peb mam li tau txais lub suab sib txawv thaum ntawd. Qhov thib ob saw, cov nyhuv voj saw, pib nrog cov teebmeem modulation. Lawv hloov lub suab, tab sis tsis txhob ncua nws (tsawg kawg rau qhov tseem ceeb). Yog li muaj cov teebmeem xws li flanger, phaser, chorus, tremolo, pitch shifter thiab octaver. Thaum kawg, peb txuas ncua kev cuam tshuam xws li ncua sij hawm thiab reverb. Raws li lub npe qhia, lawv ncua lub suab tab sis tsis hloov nws (tseem tsawg kawg rau qhov tseem ceeb). Hauv kev xyaum, peb hnov ​​​​cov suab nrov ntawm guitar, thiab tom qab ntawd nws qhov kev sib tw lossis ob peb qhov sib npaug hauv qhov me me (reverb) lossis loj dua (ntev). Ib zaug ntxiv, qhov kev txiav txim no yog qhov laj thawj, vim hais tias lub suab yuav tsum "hloov" ua ntej thiab tom qab ntawd duplicated. Nws tuaj yeem ua suab tsis zoo rau kev siv cov kev hloov pauv rau qhov "tsim" cov ntawv luam ntawm lub suab, thiab yog li qhov sib lawv liag.

Yuav ua li cas txuas cov teebmeem rau cov teebmeem voj?

Lub cable yog coj tawm ntawm lub qhov (sex) nyob rau hauv lub voj. Peb txuas nws mus rau "cov tswv yim" ntawm thawj cov nyhuv. Tom qab ntawd peb muab cov "tso tawm" ntawm cov nyhuv no nrog "cov tswv yim" ntawm cov nyhuv tom ntej. Thaum peb tau siv tag nrho cov teebmeem, peb ntsaws qhov "ouput" ntawm qhov kawg rau hauv "rov qab" qhov (socket) hauv lub voj.

Summation

Hauv lub npe peb muaj "daim duab duab ntawm ib qho yooj yim pedalboard". Qhov tseeb, tsis muaj qhov zoo li no, vim tias peb txuas cov teebmeem raws li cov cai tshwj xeeb, yog li tsis muaj dab tsi phem tuaj yeem tshwm sim yog tias peb tsis ua yuam kev ntawm polarity thaum muab khoom. Qhov yooj yim tshaj plaws "pedalboards" yog qhov ua tau ntau yam. Nws yog ib qho kev xaiv rau ntau qhov teebmeem thiab, tib lub sijhawm, kev daws teeb meem pheej yig dua. Txawm li cas los xij, tsis txhob ntshai ua kom tiav lub pedalboard uas muaj cov teebmeem ntawm tus kheej. Nws yuav tsim lub suab zoo dua thiab, qhov tseem ceeb tshaj, lub suab tshwj xeeb. Muaj pes tsawg tus guitarists nyob hauv lub ntiaj teb, muaj ntau lub tswv yim rau lub pedalboard. Yog li cia peb tsis quav ntsej li qhov teeb meem tseem ceeb.
