Kev sib dhos ntawm lub suab nthuav tawm suab tau yooj yim heev los ntawm kev siv ib tus qauv npaj hauv nws. Rau qhov no koj xav tau ntxiv lub ntim tswj, lub decoupling capacitor, lub zog muab hluav taws xob, thiab txhua lub ntim ntim uas tsim nyog.
Cov Lus Qhia
Kauj ruam 1
Yuav lub rooj tsavxwm kom tiav (ua ntej thiab thaum kawg) suab nrov ntawm UM1-3 hom ntawm xov tooj cua. Sij hawm dhau los, lawv tau teeb tsa hauv ntau lub xov tooj xim. Yog tias koj xav ua tus tswg nrov dua, yuav ob ntawm cov qauv no. Ntxiv rau lawv, tau txais lub zog hluav taws xob nrog qhov tso tawm hluav taws xob ntawm 7 txog 12 V (ruaj khov lossis tsis ruaj khov) nrog qhov tso tawm tam sim no ntawm tsawg kawg 200 mA, ntxiv rau oxide capacitors uas muaj peev xwm ntawm 1000 μF, tsim rau qhov hluav taws xob ntawm tsawg kawg 25 V, raws li cov xov tooj ntawm cov amplifier raws. Koj kuj tseem yuav xav tau ib qho lossis ob qho tib si (rau lub tso suab stereo) kuj tsis paub meej resistor ntawm pab pawg B ntawm 100 kilo ohms.
Kauj ruam 2
Txuas lub hwj huam mov rau lub rooj tsavxwm (lossis ob daim txiag), tab sis tsis txhob ntsaws rau nws. Txuas lub ntxiv rau tus lej module 4, kev rho tawm mus rau tus pin 3.
Kauj ruam 3
Coj ib tug resistor. Nthuav nws nrog cov txo qis thiab axis rau koj. Txuas cov pins laug ntawm ob ntu los ua rau tus thib rau pob ntawm ob lub laug cam. Txuas cov nruab nrab lub davhlau ya nyob twg ntawm ib ntu mus rau lub davhlau ya nyob twg thib ob ntawm ib lub rooj tsav xwm, nruab nrab lub davhlau ya nyob twg ntawm lwm ntu - mus tib lub davhlau ya nyob twg ntawm lub rooj tsav xwm thib ob. Txuas cov pins txoj cai ntawm lub resistors rau cov tso suab tawm ntawm cov paib teeb liab. Txuas cov kev sib tshuam taw tes ntawm cov seem txuas ntawm seem tsis sib xws resistor feem rau nws cov hlau. Nyob rau hauv mono amplifier, txuas ib ntu txuas rau qhov tsis paub meej resistor rau ib pawg ntawm tib txoj kev.
Kauj ruam 4
Nqa electrolytic capacitors. Muag lub davhlau ya nyob twg zoo ntawm ib qho ntawm lawv tus pin 5 ntawm ib qho ntawm cov ntsa. Hauv cov khoom siv stereophonic, ua tib txoj haujlwm rau lub ntsuas hluav taws xob thib ob thiab pawg tswj hwm thib ob.
Kauj ruam 5
Txuas tus hais lus ntawm ib qho ntawm cov kab (nrog ib qho cuam tshuam ntawm tsawg kawg 8 ohms) nruab nrab ntawm kev rho tawm ntawm lub hwj chim sib txuas thiab qhov rho tawm ntawm ib qho ntawm lub zog. Nyob hauv lub tso suab txuas ntxiv mus txuas tus ntuav lus ob hais tib yam nkaus, tab sis txuas mus rau tus lej zaum ob.
Kauj ruam 6
Nruab lub zog txuas rau hauv qhov ntim. Ntsuas ceev txhua qhov ntawm nws cov nodes thiab ntu. Qhib lub teeb liab kis thiab lub tshuab hluav taws xob loj. Kuaj xyuas yog tias nws ua haujlwm.
