Kiag li tej amplifier yog tsiag ntawv los ntawm lub siab tshaj plaws teeb liab lub zog. Qhov no yog lub zog txuas tau ntev ntev uas raug tso tawm ntawm qhov siab tshaj ntawm cov tshuab ntsuas. Tab sis qee zaum cov xwm txheej yuav tsum tau tias lub nra yuav tsum siab dua, thiab cov "khoom" ntawm lub cav tsis tuaj yeem muab qhov no. Ces koj yuav tsum ua kom lub hwj chim ntawm lub amplifier.
Cov Lus Qhia

Lub hwj chim tsuas yog lub tshuab hluav taws xob uas yog nyob rau hauv rooj plaub siv hluav taws xob cais tswj kev siv hluav taws xob nrog lub zog tsim nyog. Tawm ntawm preamplifier fais fab mov los ntawm cov qauv txheem fais fab. Qhov ntsuas voltage ntawm chav tsev stabilization yuav sib npaug rau cov khoom siv voltage tsis muaj load. Qhov no yuav tsum muaj kwv yees li ob npaug zog rau lub qub load tsis kam. Txawm li cas los xij, muaj kev phom sij uas cov zis transistors yuav tsis ciaj sia.

Yog tias thawj qhov kev xaiv tsis haum rau koj, muab lub zog ntawm cov tshuab hluav taws xob sib txawv los ntawm cov hluav taws xob cais cov hluav taws xob uas muaj cov hluav taws xob ntau dua uas muaj feem rau cov qauv ib. Nrhiav Shushurin's amplifier ncig hauv Is Taws Nem. Muaj modernized cov ntsiab lus ntawm no thiab muaj, rov ua txhua yam kom haum nws cov phiaj xwm. Raws li Circuit Court no, cov zis yuav tsum yog 100 watts.

Yog tias qhov no tsis yog rau koj, siv qhov sib txuas tau txuas ntawm qhov tsim tawm. Qhov no yuav tsum yog tus thwj tshaj plaws kev txiav txim siab, tab sis nws yuav ua rau ib tug tshaj dhau locksmith redevelopment ntawm lub amplifier thiab yuav yuav tsum tau tej yam kev txawj ntse nyob rau hauv electronics los ntawm koj.

Nyob rau hauv txhua rooj plaub, ua lub tshuab hluav taws xob cais. Hauv qhov xwm txheej txheem, tus hloov hluav taws xob 250 W, thiab tseem muaj ntau tshaj li 400 W transformer, nyuaj rau cram. Ua hloov pauv ntawm sab nraud mus rau sab hauv lub zog. Sim muab tso rau hauv qhov ntsuas hluav taws xob toroidal; tsuas yog qhov no, yog lawm, yuav raug nqi ntau dua. Tsis tas li, nco ntsoov txhim kho qhov txias ntawm lub tshuab hluav taws xob kub - nruab kiv cua lub computer ze ntawm cov transistors. Tsis txhob txuas tus hais lus tsawg dua 8 ohms.

Xav txog yuav ua dab tsi nrog kev tiv thaiv. Ntxoo lossis pov tseg tsuas yog muaj qee yam xwb! Nco ntsoov tua lub sijhawm ua haujlwm thaum lub sijhawm hluav taws xob DC tshwm. Rau chav nyob, piv txwv li, 20 square metres ob-channel 25 W yuav muaj txaus, tshwj xeeb tshaj yog xav tias lub acoustics nrog cov ntses bass thaj tsam.
