Txheem
Hauv tsab xov xwm no, kuv yuav qhia koj yuav ua li cas teeb tsa lub tsheb amplifier rau nruab nrab thiab siab zaus hauv ob peb feeb.
Suab distortion tshwm sim yog tias qhov nce tswj zaus tau teeb tsa siab dhau. Raws li ib tus neeg nyiam lub tso suab loj uas ua haujlwm hauv lub khw tso suab tsheb, kuv muaj kev paub tweaking amplifiers los txhim kho suab zoo. Koj tuaj yeem tshem tawm qhov tsis sib haum xeeb hauv koj lub tso suab los ntawm kev ua kom zoo ntawm nruab nrab thiab trebles nrog lub suab nrov thiab cov ntses bass thaj tsam. Koj tseem yuav zam lub suab distortion uas ua rau cov neeg hais lus tsis zoo thiab lwm yam khoom siv lub tso suab, thiab koj yuav tsis raug kev poob lossis nqi ntxiv los kho koj lub suab.
Ceev Txheej Txheem: Cov kauj ruam hauv qab no yuav kho koj lub tsheb amplifier kom zoo rau nruab nrab thiab siab:
- Ua si koj nyiam suab lossis suab paj nruag
- Nrhiav qhov nce tswj qab lub amplifier thiab tig nws mus rau nruab nrab.
- Kho qhov ntim kom txog li 75 feem pua
- Rov qab tswj qhov nce thiab maj mam nce qhov zaus kom txog thaum thawj cov cim qhia ntawm distortion tshwm.
- Koj tuaj yeem siv multimeter los kho qhov nce tswj.
- Tig lub HPF hloov ntawm lub amplifier thiab teem lub HPF rau 80Hz los teeb lub siab zaus.

- Tshem tawm qhov siab siab thiab poob nrog lub amp's EQ tswj.
Hauv qab no kuv yuav mus tob rau hauv qhov no.
Kho qhov nruab nrab thiab siab zaus
Qhov chaw amplifier kuj nyob ntawm hom amplifier hauv koj lub tso suab tsheb. Cov pib tshiab yuav tsum xyuas kom meej tias tsis muaj qhov tsawg zaus nyob ze lawv cov neeg hais lus.
Tsis tas li, koj xav tau qhov tsim nyog Tau Txais kom tau txais qhov tseeb ipf thiab hpf rau mods thiab maxes. Tsis txhob cuam tshuam, txawm tias nws tuaj yeem txo qis lossis tshem tawm yooj yim. Distortion tuaj yeem ua rau muaj kev puas tsuaj rau koj cov neeg hais lus thiab pob ntseg. Distortion tshwm sim thaum koj teeb tsa qhov nce qib siab dhau lawm thiab tom qab ntawd lub amplifier xa cov cim suab rau cov neeg hais lus. Suab nrov ua rau tej yam phem dua vim cov hais lus twb dhau lawm.
Yuav ua li cas thiaj tswj tau qhov nce
Ua li no:
kauj ruam 1. Ua ib zaj nkauj uas koj paub vim koj paub tias nws suab zoo li cas.
Ntawm lub amp, nrhiav qhov Gain pob qhov rooj thiab tig nws yuav luag ib nrab ntawm txoj kev - tsis txhob muab tso rau tag nrho lub zog.
kauj ruam 2. Tig lub ntim mus txog 75 feem pua - distortion pib ntawm cov ntim siab heev, yog li tsis txhob teeb lub ntim kom siab tshaj plaws.
kauj ruam 3. Mloog nkauj ua si thiab saib seb puas zoo.
kauj ruam 4. Rov qab mus rau qhov nce tswj nyob rau sab nraum qab ntawm lub amplifier thiab kho nws (nyuaj) kom txog rau thaum distortion pib. Tsis txhob tig lub ntim kom sai li sai tau thaum koj pom cov cim ntawm qhov tsis sib xws.
Xwb, koj tuaj yeem siv multimeter los kho qhov nce tswj.
Teeb tsa qhov siab tshaj plaws
Yog tias koj xav tau tsuas yog siab zaus hauv koj cov neeg hais lus, ces HPF siab dhau lim yog qhov koj xav tau. HPF thaiv cov cim qis zaus uas tsis zoo rov ua dua los ntawm cov neeg hais lus thiab tweeters. Cov teeb liab tsawg zaus tuaj yeem hlawv koj cov neeg hais lus, yog li HPF pab tiv thaiv qhov no.
Cov kauj ruam hauv qab no yuav pab koj kho lub treble:
Kauj Ruam 1: Tig lub Hpf hloov ntawm lub amplifier, los yog siv lub hau ntswj los kho nws yog tias tsis muaj qhov hloov ntawm nws.
Txhawm rau qhib qhov chaw, toggle lub high pass lim hloov ntawm koj lub amplifier. Feem ntau amps muaj qhov hloov pauv, tab sis nws nyob ntawm OEM.
Kauj ruam 2: Teem lub High Pass Lim rau 80Hz
HPFs paub txog lawv qhov kev ua tau zoo tshaj plaws ntawm 80Hz txog 200Hz, tab sis qhov qub yog qhov zoo tshaj plaws.
Txhua zaus qis dua 80Hz yuav tsum tau xa mus rau lub subwoofer thiab cov ntses bass thaj tsam. Tom qab teeb tsa HPF rau 80Hz, kho LPF kom ntes cov zaus hauv qab 80Hz. Yog li, koj tshem tawm qhov tsis sib xws hauv kev tsim tawm suab - tsis muaj zaus tawm tsis muaj kev saib xyuas.
Kev teeb tsa nruab nrab zaus
Cov neeg feem coob nug kuv seb qhov kev teeb tsa zaus twg yog qhov zoo tshaj plaws rau nruab nrab zaus. Ntawm no koj mus!
Kauj Ruam 1: Kho qhov nruab nrab ntawm 50Hz thiab 60Hz.
Nws yog ib qho tseem ceeb heev uas yuav tsum nco ntsoov tias qhov nruab nrab zaus ntawm lub tsheb lub ntsiab lus yog nyob nruab nrab ntawm 50 Hz thiab 60 Hz. Txawm li cas los xij, qee qhov audiophiles siv qhov sib npaug rau qhov saj me dua. Yog li, nrhiav lub pob qhov nruab nrab ntawm lub amp thiab teeb tsa rau 50Hz lossis 60Hz.
Kauj Ruam 2: Tshem tawm cov ntse peaks thiab dips
Txhawm rau ua qhov no, siv cov kev hloov pauv lossis qhov sib npaug. Ntse peaks thiab dips tsim lub suab hnyav, yog li nco ntsoov tshem tawm lawv nrog koj lub amp's EQ nqis. (1)
Equalizer nqis kuj cais lub suab rau hauv qis, nruab nrab thiab siab zaus. Qhov no tso cai rau koj los kho lawv li cas koj nyiam; Txawm li cas los xij, qee tus nyiam siv lub app los kho lub amplifier. Tab sis feem ntau koj yuav tsum tau teeb tsa qhov siab me ntsis siab dua qhov nruab nrab rau lub suab zoo tshaj.
Thaum kawg, thaum teeb tsa lub amplifier nqis, xyuas kom lawv phim koj cov kev xav tau. Tib neeg muaj qhov sib txawv ntawm lub suab, thiab qhov zoo li cas rau koj tej zaum yuav phem rau lwm tus. Tsis muaj suab nrov lossis suab nrov lossis suab nrov nrov; Lub ntsiab lus yog kom tshem tawm distortion.
Cov ntsiab lus tseem ceeb thiab kev teeb tsa amplifier
Nws yog ib qho tsim nyog kom nkag siab cov ntsiab lus yooj yim thiab yuav ua li cas teeb tsa lub tsheb amplifier ua ntej kho qhov nruab nrab thiab siab. Cov kev hloov pauv xws li cov suab paj nruag raug ntaus, tus hais lus, lossis tag nrho cov kab ke cuam tshuam rau nruab nrab thiab siab zaus.
Tsis tas li ntawd, muaj ob peb lub nyees khawm lossis qhov chaw nyob tom qab ntawm lub amplifier uas yuav tsum tau muaj kev paub zoo ntawm lub amplifier. Txwv tsis pub, koj tuaj yeem tsis meej pem lossis cuam tshuam qhov chaw. Hauv qab no kuv yuav tham txog cov ntsiab lus tseem ceeb hauv kev nthuav dav.
zaus
Zaus yog tus naj npawb ntawm oscillations ib ob, ntsuas hauv Hertz, Hz. [1 Hertz == 1 cycle per second]
Ntawm cov frequencies siab, cov suab paj nruag tsim cov suab nrov. Yog li ntawd, zaus yog qhov tseem ceeb ntawm nruab nrab thiab siab zaus hauv suab lossis suab paj nruag.
Cov ntses bass thaj tsam cuam tshuam nrog cov ntses bass thaj tsam, thiab koj yuav tsum muaj cov neeg hais lus ntses bass thaj tsam kom hnov cov suab qis. Txwv tsis pub, cov xov tooj cua tsis tshua muaj suab nrov yuav ua rau lwm tus hais lus puas tsuaj.
Nyob rau hauv sib piv, siab zaus yog reproduced los ntawm cov twj paj nruag xws li cymbals thiab lwm yam high-frequency khoom. Txawm li cas los xij, peb tsis tuaj yeem hnov txhua zaus - qhov ntau zaus rau pob ntseg yog 20 Hz txog 20 kHz.
Lwm zaus units hauv tsheb amplifiers
Qee lub tuam txhab tau teev cov zaus hauv decibels (dB) ntawm LPF, HPF, super ntses bass thaj tsam, thiab lwm yam.
Tau txais (input rhiab heev)
Gain piav qhia qhov rhiab heev ntawm lub amplifier. Koj tuaj yeem tiv thaiv koj lub tso suab ntawm lub suab distortion los ntawm kev kho qhov nce raws li. Yog li, los ntawm kev kho qhov nce, koj ua tiav qhov ntim ntau dua lossis tsawg dua ntawm cov tswv yim ntawm lub amplifier. Ntawm qhov tod tes, ntim tsuas yog cuam tshuam rau cov lus tso zis.
Kev nqis peev ntau dua ua rau lub suab ze dua rau kev cuam tshuam. Hauv cov hlab ntsha no, koj yuav tsum tau kho qhov kev nce qib kom tshem tawm kev cuam tshuam ntawm cov lus tso tawm. Koj yuav xyuas kom meej tias tus neeg hais lus tsuas yog muab lub zog txaus los tshem tawm cov suab distortion.
Lub Caij Hla
Crossovers xyuas kom meej tias lub teeb liab raug mus txog nws txoj cai tsav tsheb. Qhov no yog ib qho khoom siv hluav taws xob tsim rau hauv lub tsheb lub suab hluav taws xob kom cais cov suab zaus mus rau ntau qhov sib txawv. Txhua qhov ntau zaus raug xa mus rau tus neeg hais lus tsim nyog - tweeters, subwoofers thiab woofers. Cov tweeters tau txais cov zaus siab, thaum lub subwoofers thiab woofers tau txais qhov qis tshaj plaws.
High Pass Lim
Lawv txwv cov zaus uas nkag mus rau cov neeg hais lus tsuas yog cov zaus siab - mus txog qhov txwv. Raws li, tsawg zaus raug thaiv. Yog li, cov ntxaij lim dej siab dhau yuav tsis ua haujlwm nrog tweeters lossis cov neeg hais lus me me uas tuaj yeem raug puas tsuaj thaum cov teeb liab tsawg dhau los ntawm lub lim.
Low Pass Filters
Low pass filters yog qhov opposite ntawm high pass lim. Lawv tso cai rau koj xa cov zaus qis dua (txog ib qho kev txwv) rau subwoofers thiab woofers - cov neeg hais lus ntses bass thaj tsam. Tsis tas li ntawd, lawv lim tawm suab nrov los ntawm cov cim suab, tawm hauv cov suab bass thaj tsam qab.
Summing txog
Kev teeb tsa lub tsheb amplifier rau nruab nrab thiab siab zaus tsis yog qhov nyuaj. Txawm li cas los xij, koj yuav tsum nkag siab txog cov ntsiab lus tseem ceeb lossis cov ntsiab lus ntawm lub suab tuning - zaus, crossovers, nce tswj, thiab dhau cov lim dej. Nrog koj cov suab paj nruag nyiam thiab kev paub zoo, koj tuaj yeem ua tiav cov suab nrov zoo hauv koj lub tso suab. (2)
