Yuav ua li cas xaiv amplifiers thiab hais lus rau bass guitars?

Puas yog lub bass guitar tseem ceeb dua lub amplifier uas peb txuas nws? Cov lus nug no yog tawm ntawm qhov chaw, vim hais tias cov ntses bass thaj tsam uas tsis zoo yuav ua rau lub suab tsis zoo ntawm lub suab nrov zoo, tab sis cov cuab yeej zoo ua ke nrog lub suab tsis zoo yuav tsis zoo ib yam. Hauv phau ntawv qhia no, peb yuav hais txog amplifiers thiab hais lus nrov.

Lub teeb lossis transistor?

"Tsev" - kev lig kev cai rau xyoo lawm, classic, rounder suab. Hmoov tsis zoo, kev siv lub raj xa hluav taws xob suav nrog qhov yuav tsum tau hloov cov raj ntawm lub sijhawm, uas ua rau cov nqi khiav lag luam ntawm lub raj "furnaces", uas tseem kim dua lawv cov neeg sib tw. Qhov kev sib tw no muaj xws li transistor amplifiers. Lub suab tsis sib haum rau lub tshuab raj amplifiers, txawm hais tias niaj hnub no cov thev naus laus zis tau txav nrawm heev uas cov engineers tau los ze zog mus txog rau cov yam ntxwv sonic ntawm cov raj los ntawm transistors. Nyob rau hauv lub "transistors" koj tsis tas yuav hloov cov hlab, thiab dua li, lub transistor "furnaces" yog pheej yig dua lub raj. Ib qho kev daws teeb meem yog hybrid amplifiers, sib txuas lub raj preamplifier nrog lub transistor fais fab amplifier. Lawv pheej yig dua li lub raj amplifiers, tab sis tseem ntes tau qee lub suab "tube".

"Musical" cov neeg nyob sib ze

Koj yuav tsum xav txog qhov tseeb tias txhua lub raj amplifier yuav tsum tau tig mus rau ib theem kom suab zoo. Transistor amplifiers tsis muaj teeb meem nrog qhov ntawd, lawv suab zoo txawm tias qis dua qib. Yog tias peb tsis muaj cov neeg nyob ze ua si, piv txwv li, lub suab raj lossis lub saxophone, disassembling "teeb" tuaj yeem yog qhov teeb meem loj. Tsis tas li ntawd, nws yog aggravated los ntawm qhov tseeb hais tias tsawg zaus yog zoo dua kis tau tus kab mob ntev dua. Nyob hauv lub nroog, koj tuaj yeem ua ib nrab ntawm qhov thaiv tsis nyiam peb. Peb tuaj yeem ua si ntsiag to hauv tsev ntawm lub tshuab hluav taws xob loj-xeev thiab pob zeb tawm ntawm kev hais kwv txhiaj. Koj tuaj yeem xaiv ib lub raj me me amplifier nrog tus hais lus me me, tab sis hmoov tsis muaj ib qho "tab sis". Ntawm cov ntses bass thaj tsam, cov neeg hais lus me me suab tsis zoo dua li cov loj vim tias lawv tsis zoo txaus los xa cov zaus tsawg, tab sis ntau ntxiv tom qab ntawd.

Lub taub hau + kem lossis combo?

Combo yog ib qho amplifier nrog lub suab nrov hauv ib lub tsev. Lub taub hau yog chav tsev uas nthuav tawm cov teeb liab los ntawm lub cuab yeej, txoj haujlwm uas yog coj cov teeb liab uas twb muaj lawm mus rau lub suab nrov. Lub taub hau thiab kem ua ke yog ib pawg. Qhov zoo ntawm lub comba yog twv yuav raug hu zoo dua mus. Hmoov tsis zoo, lawv ua rau nws nyuaj los hloov lub suab nrov, thiab dhau li ntawd, cov transistors lossis cov raj xa ncaj qha rau lub suab nrov. Qhov no muaj qhov tsis zoo rau lawv txoj haujlwm rau qee qhov. Nyob rau hauv ntau lub combos nws muaj tseeb hais tias ib tug nyias hais lus yuav tsum tau kev cob cog rua, tab sis txawm yog hais tias peb tua lub built-in ib tug, peb tseem raug yuam kom thauj tag nrho cov qauv combo thaum tsiv lub amplifier los ntawm qhov chaw mus rau qhov chaw, tab sis lub sij hawm no nrog ib tug. cais tus neeg hais lus. Nyob rau hauv cov ntaub ntawv ntawm stacks, peb muaj ib tug heev mobile lub taub hau thiab tsawg mobile txhua, uas nyob rau hauv ua ke nrog yog ib qho teeb meem nyuaj rau kev thauj mus los. Txawm li cas los xij, peb tuaj yeem xaiv lub taub hau nrov nrov raws li peb nyiam. Tsis tas li ntawd, cov transistors lossis cov raj hauv "lub taub hau" tsis raug lub suab nrov, vim tias lawv nyob hauv ib lub tsev txawv dua li cov hais lus nrov.

Hais lus loj thiab tus naj npawb ntawm kab

Rau bass guitars, 15 "hais lus yog tus qauv. Nws yog ib qho tsim nyog yuav tsum tau saib xyuas seb lub suab nrov (qhov no kuj tseem siv tau rau lub suab nrov nrov hauv combach) yog nruab nrog lub tweeter. Feem ntau nws yog 1 "thiab nyob rau hauv tib kem raws li tus neeg hais lus tseem ceeb. Nws yog qhov tseeb tsis tsim nyog, tab sis ua tsaug rau nws, cov ntses bass thaj tsam tau txais lub suab nrov dua, qhov tseem ceeb hauv kev tawg los ntawm kev sib xyaw thaum ua si nrog koj cov ntiv tes lossis plaub, thiab tshwj xeeb tshaj yog nrog cov txheej txheem clang.

Qhov loj dua lub suab nrov, qhov zoo dua nws tuaj yeem ua haujlwm tsawg zaus. Tias yog vim li cas bassists feem ntau xaiv cov hais lus nrov nrog 15 "lossis txawm tias 2 x 15" lossis 4 x 15 "hais lus. Qee zaum kev sib txuas nrog 10 "hais lus kuj tau siv. Lub 15 "hais lus muab cov ntses bass thaj tsam zoo, thiab 10" yog lub luag haujlwm rau kev sib tsoo hauv pawg sab sauv (lub luag haujlwm zoo sib xws yog ua los ntawm tweeters ua rau cov neeg hais lus nrog 15 "hais lus). Qee lub sij hawm cov ntses bass thaj tsam txawm txiav txim siab mus txawm tias 2 x 10 "lossis 4 x 10" los hais txog qhov kev sib tw hauv pawg sab saud. Cov ntses bass thaj tsam tawm ntawm qhov ntawd yuav nyuaj dua thiab tsom mus ntxiv, uas tej zaum yuav xav tau ntau zaus.

Muaj qee txoj cai kom nco ntsoov thaum xaiv kab. Kuv yuav muab txoj kev nyab xeeb tshaj rau koj. Muaj, ntawm chav kawm, lwm tus, tab sis cia peb tsom mus rau cov tsis muaj kev pheej hmoo siab. Yog tias koj tsis paub meej txog dab tsi, nrog tus kws tshaj lij. Tsis muaj hluav taws xob.

Thaum nws los txog rau lub hwj chim, peb tuaj yeem xaiv lub suab nrov sib npaug rau lub zog ntawm lub amplifier. Peb kuj tuaj yeem xaiv lub suab nrov nrog lub zog qis dua lub suab nrov, tab sis tom qab ntawd koj yuav tsum nco ntsoov tsis txhob disassemble lub amplifier ntau dhau, vim tias koj tuaj yeem ua rau cov neeg hais lus puas. Tsis tas li ntawd, koj tuaj yeem xaiv lub suab nrov nrog lub zog siab dua li lub suab nrov. Nyob rau hauv rooj plaub no, koj yuav tsum tsis txhob overdo nws nrog disassembled lub amplifier, thiaj li tsis mus ua puas nws, vim hais tias tej zaum nws yuav tshwm sim hais tias peb yuav sim siv tag nrho cov peev xwm ntawm cov neeg hais lus ntawm tag nrho cov nqi. Yog tias peb siv qhov nruab nrab, txhua yam yuav tsum zoo. Ib qho ntxiv. Piv txwv li, lub amplifier nrog lub zog ntawm 100 W, hais lus, "xa" 200 W rau 100 W hais lus. txhua tus ntawm lawv.

Thaum nws los txog rau impedance, nws txawv me ntsis. Ua ntej koj yuav tsum xyuas seb koj puas muaj kev sib txuas los yog sib txuas. Feem ntau, nws tshwm sim thaum uas tig mus. Yog li yog tias peb muaj ib qho kev sib txuas mus rau ib qho amplifier, piv txwv li nrog lub impedance ntawm 8 ohms, peb txuas ib tus hais lus 8-ohm. Yog tias koj txiav txim siab siv 2 lub suab nrov, koj yuav tsum siv 2 16 - ohm loudspeakers rau tib lub amplifier. Txawm li cas los xij, yog tias peb muaj kev sib txuas ua ke, peb kuj txuas ib tus neeg hais lus 8-ohm mus rau lub amplifier nrog lub impedance ntawm 8 ohms, tab sis qhov no yog qhov zoo sib xws kawg. Nyob rau hauv cov ntaub ntawv ntawm ib tug series kev twb kev txuas, ob 2-ohm kab yuav siv tau rau tib lub amplifier. Qee qhov kev zam tuaj yeem ua tau, tab sis qhov yuam kev tuaj yeem ua rau muaj qhov tshwm sim loj. Yog tias koj tsis paub meej 4%, ua raws li cov cai no.

Yuav nrhiav dab tsi?

Bass amplifiers feem ntau tsuas muaj 1 channel uas huv si, los yog 2 channel uas huv si thiab distorted. Yog hais tias peb xaiv lub amplifier yam tsis muaj distortion channel, peb yuav plam qhov tau txais lub suab distorted tsuas yog ua tsaug rau lub amplifier. Qhov no tsis yog qhov teeb meem loj. Nyob rau hauv tas li ntawd, tsuas yog muas sab nraud distortion. Koj yuav tsum tau them sai sai rau qhov kho. Qee cov amplifiers muaj ntau pawg EQ rau cov neeg ib leeg, tab sis feem ntau tsuas yog muab "bass - nruab nrab - treble" EQ. Heev feem ntau, bass amplifiers yog nruab nrog ib tug limiter (ib tug tshwj xeeb teeb compressor), uas tiv thaiv lub amplifier los ntawm pliaj distortion. Tsis tas li ntawd, koj tuaj yeem nrhiav tau lub compressor classic uas sib npaug ntawm cov qib ntim ntawm kev ua si nruj thiab nruj. Qee zaum kev hloov kho thiab cov teebmeem spatial tau tsim hauv, tab sis cov no tsuas yog ntxiv thiab tsis cuam tshuam rau lub suab yooj yim. Yog tias koj xav siv cov kev hloov pauv sab nraud thiab cov teebmeem ib puag ncig, xyuas seb lub tshuab hluav taws xob puas muaj lub voj voog FX built-in. Cov kev hloov pauv thiab cov teebmeem spatial ua haujlwm zoo dua nrog lub amp los ntawm lub voj voog dua li ntawm cov ntses bass thaj tsam thiab lub amp. Lub wah - wah, distortion thiab compressor yog ib txwm ntsaws ntawm lub amplifier thiab lub ntsuas. Nws yog ib qho tseem ceeb heev uas yuav tau xyuas seb lub amplifier muaj cov khoom tso tawm. Cov ntses bass thaj tsam feem ntau kaw linearly, thiab tsis muaj cov zis zoo li no tsis tuaj yeem ua tau. Yog hais tias ib tug neeg xav tau lub mloog pob ntseg tso zis, nws tseem tsim nyog ua kom paub tseeb tias nws yog nyob rau hauv lub amplifier muab.

Summation

Nws tsim nyog txuas cov ntses bass thaj tsam rau ib yam dab tsi tseem ceeb, vim hais tias lub luag hauj lwm ntawm lub amplifier tsim lub suab yog loj heev. Qhov teeb meem ntawm "lub qhov cub" yuav tsum tsis txhob kwv yees yog tias koj xav kom suab zoo.
