Ntau tus neeg nkauj paj nruag nyiam sau lawv cov kev ua si thiab kev ua yeeb yam ntawm kev hais lus sib hais nrog cov twj paj nruag qhuav, tshwj xeeb cov twj paj nruag tsis muaj zog thiab luv luv. Cov no suav nrog tshwj xeeb tsis muaj kev zam ntawm daim ntawv lo, tshwj xeeb yog cov hluav taws xob guitarists, uas lawv tau ua dua tshiab tsis tuaj yeem hais tawm, tsis muaj me nyuam muaj suab. Nyob rau hauv tib txoj hauj lwm muaj ob qho tib si cov kws luam ntawv ntawm lwm cov ntawv tshaj tawm hauv hluav taws xob lossis hluav taws xob cov twj paj nruag.
Lub suab muaj zog muaj zog tau pom hauv cov twj paj nruag me me (raj nplaim, nqa pob tw, cov ris tsho thiab lwm cov kav dej). Nyob rau hauv cov kev hais lus loj loj, txawm tias Bayan thiab accordion yuav tau hnov heev tsis muaj zog. Tau kawg, tseem muaj hluav taws xob, tsim tsis tsuas yog rau kev sib tw ntau dua, tab sis kuj tseem yuav sib tw nrog lwm cov cuab yeej txawm hais tias cov kev hais lus, xws li chaw ntau pob thiab cov chaw ntau pob.
Xav txog hauv cov kab lus no tshwj xeeb ntawm lub teeb Guitar guitar amplifiers rau lub tsev thiab lawv teeb tsa ntawm lawv tus kheej.
Peculiarities
Rau cov guitarists, tshwj xeeb tshaj yog cov neeg uas ua ntawm kev sib hais los yog ua hluav taws xob guitar, nws yog ib qho tseem ceeb heev los xaiv lub suab zoo tshaj plaws, muab cov suab zoo sib dhos. Txawm li cas los xij, tsis yog txhua novice cov suab paj nruag muaj txoj hauv kev los txais cov cuab yeej kim kim uas muaj cov tshuab kws paub zoo koom nrog.
Nws tau ntev tau paub tias Lub suab nrov tshaj plaws tuaj yeem tsim lub teeb guitar guitar amplifiers (combians). Lub suab no tsis mus rau ib qho kev sib piv nrog cov khoom sib piv niaj hnub ntawm cov chips thiab ntxim nyiam thiab ntxim nyiam mloog nrog ntses bass lossis suab paj nruag siab. Tab sis tus nqi ntawm txawm tias tsis muaj kev ua tsis tau ua los ntawm Ntiaj Teb Hom yog ib qho kev txiav txim siab dua li kev sib xyaw nrog cov ua ke nrog cov semiconductors.
Muaj tseeb, cov teeb ua kom zoo tshaj plaws muaj qee qhov tsis zoo uas tsis tuaj nyob hauv cov khoom siv analog. Cov no suav nrog:
- kev sib tsoo thiab loj loj ntawm cov khoom tiav;
- Kev ntseeg tau tsis txaus ntawm lub teeb sib piv nrog cov transistors;
- Muaj zog cua sov ntawm qhov chaw, uas tuaj yeem ua rau kev puas tsuaj rau cov saw hluav taws xob thiab tsis ua tiav ntawm qee yam ntawm cov khoom siv;
- Kev ua haujlwm tsis muaj peev xwm ntawm lub teeb txawb uas tsim nyog vim tias muaj cov khoom siv hluav taws xob thiab maj mam muab cov khoom siv hluav taws xob ntau lawm ntawm cov khoom siv qub thiab khoom siv.
tiamsis Cov teeb meem no tsis txwv cov suab paj nruag ntawm txoj kev kom tau txais lub suab zoo ntawm lawv cov guitars. Yog li ntawd, feem ntau cov guitarists sim khaws cov khoom siv hauv tsev, thiab tom qab ntawd lawv yuav khaws tau tus nqi pheej yig dua li cov cuab yeej siv hluav taws xob.
Nrhiav cov kev xaiv zoo tshaj plaws rau koj tus kheej, nws yog qhov tsim nyog los tshawb xyuas nws zoo, sau cov qauv hluav taws xob ntawm lub zog hluav taws xob thiab rau nws lub hauv paus (chassis), ntawm txhua qhov teeb tsa tag nrho ntawm qhov chaw nyob thiab yog ua los ntawm cov saw mounting nruab nrab ntawm lawv.
Tes Cuab Yeej thiab Cov Ntaub Ntawv
Rau kev kawm hauv tsev ntawm kev ua si guitar lossis cov ntaub ntawv ntawm cov haujlwm yooj yim heev rau cov khoom siv tawm yooj yim ntawm 1.5-3.0 W. Nws yuav txaus kom tau ua tiav cov txheej txheem ntawm kev ua si, ua cov nkauj zoo nkauj tsuas yog cov nkauj ua ke nyob hauv koj tus kheej hauv qab ntawm cov leeg ntawm cov neeg nyob ze. Yog li ntawd, koj tuaj yeem xaiv qhov kev xaiv ntawm tus kheej tsim amplifier nrog cov ntsiab lus rau hluav taws xob Circuit Court:
- Teeb lub teeb-triode 6n1p (lossis nws qhov analogues: 6n3p, 6n2p, 6n23p), tsim nyog rau lub sijhawm ua ntej (kev tawm tswv yim) cascade ntawm tag nrho cov txheej txheem;
- 6P14P teeb (PENERER), koom rau qhov kawg (tawm) schema cascade;
- Cov tso zis Audio Transformer Twz-1-1, tsim los rau lub zog tam sim no tsis pub dhau 2 xyoos Ohms, lossis tsis tau tshwj xeeb trect hom Transformers, tab sis lawv yuav tsis muaj peev xwm ua rau muaj kev cuam tshuam zoo ntawm lub suab);
- 560 Kω nkag resistor.
- Lub resistor ntawm cathode ntawm lub teeb-trio yog 0.5 w, ntawm anode - 0.5-1.0 w;
- Capacitor nyob rau hauv shunt nrog ib tug Cathode Resistor teeb-trio nrog lub thawv siab tshaj plaws thiab ib qho hluav taws xob ntawm 10 V;
- Tus condenser ntawm cov kab kev sib txuas lus ntawm cov cascades yuav tsum yog cov voltage los ntawm tib kab tuaj yeem yog nrog cov tsis tau los ntawm 100000 kω;
- Lub resistor ntawm cathode ntawm lub teeb bither yuav tsum muaj zog tshaj nyob rau hauv lub teeb condenser muaj qhov muaj peev xwm tshaj tawm rau lub shunt hauv lub trigger ncig;
- Tus hais lus yog 8 ohms.
Rau lub platform, koj tuaj yeem thov cov ntawv tuab duralumin raws li cov khoom siv, khoov nws mus rau hauv daim ntawv sib cav, nco qab ntawm lub thawv, lossis yuav cov khoom tiav. Qee tus neeg siv siv lub computer qub rau lub platform nyob rau hauv kev tshaj tawm sai, tog ib feem ntawm lub hau ntawm qhov loj me.
Ib qho ntxiv, cov ntaub ntawv yuav xav tau xaim rau mounting hluav taws xob hluav taws xob ntawm lub suab hluav taws xob, thiab cov ntsaws rau hauv cov pob thiab cov hlua txuas ntxiv rau cov cuab yeej rau lub qhov cuab yeej.
Los ntawm cov cuab yeej mounting, solder yuav tau npaj thiab cov hlau nrog cov khoom siv hlau, kua nplaum, ntsuas cov kev cai thiab cov cim rau khij.
Cov txheej txheem ntau lawm
Cov kev thov npaj rau kev tsim cov khoom siv hluav taws xob tsawg yog ob theem system uas cov theem converter cascade tuaj yeem nkag mus. Nws cov kev ua haujlwm nyob hauv kev sib cais ntawm lub teeb liab ntawm cov inlet ntawm lub inlet rau lub amplifier ua ob ib nrab-vuag, uas yog rov qab los ntawm theem. Cov theem Inverter cov phiaj xwm yog qhov yooj yim heev thiab muab cov txiaj ntsig zoo los txhim kho kev ua haujlwm ntawm lub suab nrov, tshwj xeeb tsis yog, tshwj xeeb yog lub suab yog heev distorted. Tab sis rau cov hluav taws xob tsawg amplifiers, cov cuab yeej no yuav muaj txiaj ntsig zoo.
Thaum txhim kho cov txheej txheem hluav taws xob ntawm lub amplifier ntawm lub amplifier, cov kws tshaj lij qhia txog kev txiav txim ua haujlwm tsis yog los ntawm thawj theem (nkag), tab sis txij hnub thib ob.
Ua ntej, sau pento ib feem ntawm cov txheej txheem nrog tus hloov pauv, hais lus, lub teeb thiab shunt, thiab tom qab ntawd cov cathhode ib feem ntawm Circuit Court mus rau hluav taws xob network. Yog tias txhua yam zoo, tom qab ntawd hauv qhov muaj zog koj tuaj yeem hnov cov crackle lossis keeb kwm thaum lub teeb kov tau los ntawm tes. Tom qab xws li kev sim, koj tuaj yeem ua haujlwm txuas ntxiv. Txwv tsis pub, koj yuav tsum tau saib qhov txhaum thiab tshem tawm nws. Tom qab sau thawj theem, koj yuav tsum tau xyuas cov haujlwm ntawm cov txheej txheem. Xws li kev sib cais ntawm mounting rau cov kauj ruam yuav txiav txim siab qhov txheej txheem ntawm cov phiaj xwm yog malfunction yog ib qho keeb kwm undesirable tshwm sim hauv qhov muaj zog.
Qee lub sij hawm nws ntog los ntawm kev sim los tsim cov kev hloov kho zaum kawg ntawm lub amplifier kom tau txais cov zis zoo dua ntawm cov twj paj nruag. Rau qhov no, nws yuav muaj peev xwm hloov qee cov ntsiab lus ntawm cov analogues nrog lwm cov tsis muaj peev xwm (muaj peev xwm ntawm kev tsim tawm, thiab lwm yam). Nws tshwm sim uas lub teeb txawb tau hloov ntawm theem ntawm kev teeb tsa lub suab.
Yuav ua li cas ua lub teeb guitar amplever nrog koj tus kheej tes, saib hauv cov yeeb yaj kiab hauv qab no.
