Hauv phau ntawv qhia no kuv yuav qhia koj li cas tuaj yeem ua rau koj tus kheej heev bass/guitar pre-amplifier thiab lub thawv cuam tshuam. Kuv xaiv los ua lub thawv sib xyaw ua ke, uas sib xyaw ua ke "Black Ice" lossis "Electra Distortion" cuam tshuam qhov cuam tshuam nrog "Bazz Fuss" fuzz effect. Qhov no yog combo zoo heev ntawm kev ua rau koj zoo li lub pob zeb/grunge lub hnub qub. Lub caij no lub tshuab ua suab nrov ua ntej ua rau cov tswv yim ntau, ntau, nrov dua rau qhov ntxiv "oompf".

Kev tsis lees paub: Qhov no yog txoj haujlwm nyuaj heev los sim yog tsim nws mus rau qhov zoo me me. Kuv tsis pom zoo kom ua kom nws me me li kuv tau ua. Tsis tas li ntawd, es tsis yog phau ntawv qhia meej txiav txim siab qhov kev qhia no ntau dua li phau ntawv qhia dav dav. Raws li cov ntsiab lus ntawm koj tsim thiab koj cov kev xav tau yuav yog tus kheej thiab sib txawv. Kuv tsis muaj lub luag haujlwm rau ib yam dab tsi yog tias koj sim tsim qhov no thiab sim muab nws tso rau hauv daim ntawv me me ua rau nws tawg lossis lwm yam.

Kauj Ruam 1: Txog Circuit (s)

Ua ntej-amp:

Lub tshuab ua ntej ua ntej yog ua raws TDA2822 lub tshuab ua kom nrov nrov, uas tau teeb tsa hauv hom choj. Txoj hauv kev no muaj ob qhov txiaj ntsig ntawm tus kheej; ib qho uas mus rau cov txiaj ntsig zoo sib xws Circuitry thaum lwm qhov mus rau bypass/amplified output. Nov yog lub hauv paus tseem ceeb thiab yog vim li cas rau qhov kev tsim no; nws yog thawj zaug yuav tsuas yog qhov pre-amp, kom txog rau thaum cov teebmeem tau ntxiv. Kuv tau siv txhua yam khoom kuv muaj hauv tes thiab ua haujlwm, tab sis txij li lub nti no txhais tau tias yog lub zog tso suab amp thiab tsis yog pre-amp nws tseem muaj qee qhov teeb meem; feem ntau yog qee qhov kev sib txawv thaum lub ntim (ntawm cov ntses bass thaj tsam) tau dhau mus siab dhau, tab sis tsis muaj dab tsi uas cuam tshuam rau kev ua haujlwm ib txwm muaj (tej zaum qhov kev cuam tshuam no tuaj yeem suav tias yog qhov cuam tshuam thib peb!)

Cov Teeb Meem:

Ob qho kev cuam tshuam tsis zoo thiab cuam tshuam cuam tshuam yog qhov ntau thiab yog ib puag ncig ib puag ncig-emitter transistor amplifier. Yog li ntawd vim li cas kuv thiaj tuaj yeem sib tshuam lawv cov kab hluav taws xob, ntxiv lub zog ntsuas kom sib xyaw cov nyiaj ntawm txhua qhov txiaj ntsig. Kuv qhia koj kom ua si ib puag ncig nrog lub voj voog no, sim sib txawv diodes, resistor thiab potentiometer qhov tseem ceeb kom txog thaum koj pom dab tsi ua haujlwm rau koj. Oddly txaus kuv kuj pom tias thaum ua khub nrog TDA2822 pre-amp, lub Circuit Court no muaj qee qhov cuam tshuam tsis zoo uas suab zoo li "wobble" uas yog qhov tau txais txiaj ntsig.

Nws suab li cas:

Hauv cov kauj ruam no muaj cov vis dis aus hais txog yuav ua li cas cov suab sib txawv.

Kauj ruam 2: Schematic

Saum toj no yog cov txheej txheem ntawm txhua yam uas nyob hauv lub thawv. Pre-amp tsuas yog TDA2822 IC hauv tus choj

teeb tsa, tib yam li cov ntawv teev tseg (ib qho kev hloov pauv me ntsis: tsuas yog hloov 10uF capacitor rau 100uF ib qho). Cov txiaj ntsig ntawm pre-amplifier mus los ntawm DPDT ntsuas phoo-hloov uas xaiv yog tias ua kom nrov nrov lossis ua kom lub teeb liab thiab cov teebmeem yuav tsum tau tso tawm. Ib lub zog ntsuas hluav taws xob tswj kev sib xyaw ntawm qhov tsis sib xws thiab cuam tshuam cuam tshuam thiab lwm qhov yog kev tswj ntim yooj yim. Tag nrho cov Circuit Court tau siv hluav taws xob 1000mAh lithium polymer roj teeb, thiab tig nws tus kheej thaum lub TRS txuas tau txuas rau hauv lub mloog pob ntseg 3.5mm. Kuv tau xub siv ob lub roj teeb AAA, tab sis lub Circuit Court muaj qhov siab me ntsis tam sim no kos ntawm kwv yees li 15mA, nrog Li-Po no nws yuav siv sijhawm kwv yees li peb hnub ntawm kev ua haujlwm txuas ntxiv thiab nws tuaj yeem them rov qab, nrog rau qhov yooj yim ntxiv TP4056 charger module.
