Lub taub hau amp yog ib hom Amplifier uas tsis muaj cov neeg hais lus. Hloov chaw, nws yog txhais tau tias yuav tsum tau siv nrog lub txee sab nraud. Qhov no ua rau nws txav tau ntau dua li lub tshuab hluav taws xob combo, uas muaj ob qho tib si amplifier thiab ib lossis ntau tus neeg hais lus hauv lub txee ntoo.
Amp taub hau feem ntau muaj zog dua li combo amps, ua rau lawv xaiv zoo dua rau qhov chaw loj dua. Lawv kuj nyiam tsim lub suab huv dua, vim tias cov neeg hais lus tsis raug tsav nyuaj.
Txawm li cas los xij, qhov no tuaj yeem ua rau lawv nyuaj dua kom tau lub suab zoo tawm yog tias koj tsis yog tus neeg ua si paub txog.
Introduction
Lub taub hau amplifier yog hom khoom siv suab uas muab cov hwj chim thiab tone rau amplifier. Nws yog lub hwj chim qhov chaw rau lub amplifier thiab muab lub siab voltage hluav taws xob rau cov neeg hais lus. Lub taub hau amplifier feem ntau yog siv thaum koj xav tau wattage ntau dua li qhov muaj los ntawm combo lossis pawg amplifier. Cia peb dhia dej rau hauv cov ntsiab lus kom nkag siab meej thaum koj yuav tsum xaiv lub taub hau amplifier.
Lub taub hau amplifier yog dab tsi?
Lub taub hau amplifier yog cov khoom siv hluav taws xob hluav taws xob uas ua kom lub suab nrov ua ntej nws xa mus rau cov khoom nrov nrov. Hauv cov suab paj nruag amplifiers, suav nrog guitar, ntses bass thaj tsam thiab keyboard amplifiers, lub taub hau amplifier pab hloov cov teeb liab uas tsim los ntawm cov khoom siv lossis microphones. Feem ntau hais lus, thaum xaiv lub taub hau amplifier, muaj ntau yam tseem ceeb los xav txog.
Lub wattage thiab impedance yog qhov tseem ceeb. Wattage yog qhov ntsuas ntawm lub zog uas lub amp tuaj yeem tsim tau. Impedance yog hais txog tus nqi ntawm qhov tsis kam ntawm qhov chaw thiab thauj khoom hauv ib qho hluav taws xob hluav taws xob. Cov impedance siab dua tso cai rau cov zis ntau dua los ntawm koj cov neeg hais lus uas muaj teeb meem tsawg dua los ntawm cov khoom tsis sib haum. Lub taub hau amplifier kuj txawv ntawm lawv cov hom xws li cov raj lossis cov khoom siv hauv lub xeev, uas tsim cov suab analog lossis digital nyob ntawm qhov nyiam tsim.
Feem ntau, xaiv lub taub hau amplifier nyob ntawm tus kheej nyiam thiab npaj siv cov cuab yeej amplifying system. Yog tias koj npaj yuav ua si qhov chaw me me xws li nightclubs lossis bars uas tsis muaj PA systems, koj tsuas yog xav tau 15-30 watts qhov chaw loj dua yuav xav tau tsawg kawg yog 300 watts yam tsawg kawg nkaus nrog cov wattage ntau dua kom pom tseeb thiab muaj nyob hauv thaj chaw loj. Tau kawg nyob ntawm koj cov kev xav tau koj kuj yuav xav tau kev sib txuas ntawm ob qho tib si uas yog vim li cas nws tseem ceeb kom qhia koj tus kheej txog txhua yam kev xaiv muaj ua ntej txiav txim siab yuav khoom!
Hom Amplifier Heads
Lub taub hau amplifier yog lub tshuab hluav taws xob hluav taws xob uas muaj peev xwm ua kom muaj zog ib lossis ntau lub suab nrov. Nws feem ntau yog siv los tsim lub suab loj dua rau kev ua yeeb yam nyob. Muaj ntau ntau hom amplifier lub taub hau xaiv los ntawm, txhua tus muaj lawv tus kheej lub zog thiab qhov tsis zoo ntawm lub suab zoo, lub zog tso zis, thiab ntau dua. Hauv qab no, peb yuav saib qee yam ntawm cov hom nrov tshaj plaws ntawm lub taub hau amplifier thiab sib tham thaum twg nws yuav ua rau kev txiav txim siab xaiv txhua tus.
Tau-xeev
Solid-state amplifier taub hau muab kev ntseeg tau zoo thiab raug nqi tsawg dua li lub raj amplifiers. Cov taub hau no tau txais lawv lub npe los ntawm kev tsim tawm ntawm cov khoom siv hluav taws xob hauv lub xeev. Hom lub taub hau no ua rau lub suab sib txawv dua li lub tshuab ua suab paj nruag thiab tuaj yeem muaj lub suab hnyav dua, lub suab zoo dua nrog lub suab qis dua. Nws yog qhov kev xaiv zoo yog tias koj xav tau lub suab zoo meej uas zoo thaum kaw hauv lub studio vim nws qhov meej, nthuav dav thiab punchy nres. Solid-state amplifier taub hau tuaj yeem pom muaj zog lossis tsis muaj zog, yog li yog tias koj xav tau kev txav mus los, cov no yog qhov kev xaiv zoo tshaj plaws vim tias lawv feem ntau sib dua thiab yuav tsis tas yuav tsum muaj kev nthuav dav ntxiv uas yuav tuaj nrog lawv cov kwv tij neej tsa.
Tube
Tube amplifier hau yog guitar amplifiers uas siv lub tshuab nqus tsev vacuum nyob rau hauv preamplifier thiab tso zis theem, as opposed to transistors. Tube amps tau nyob ib puag ncig txij li xyoo 1940s thiab tsis ntev los no tau pom qhov rov qab los raws li cov kws ntaus kis las tau rov tshawb pom lub suab tshwj xeeb uas tsuas yog lub raj amp taub hau tuaj yeem muab tau.
Tube amp taub hau zoo li suab sov thiab meej. Lawv kuj teb tau zoo rau kev sib txawv ntawm kev ua si los ntawm kev sib tw muag muag mus rau kev sib tsoo hnyav. Ntau lub raj amps muaj ntau txoj hauv kev, tso cai rau koj hloov ntawm qhov chaw sai sai rau ntau lub suab. Ib lub raj amp lub taub hau yuav yog qhov loj heev piv rau cov qauv transistor, tab sis niaj hnub no cov kev xaiv me me thiab pheej yig yog portable heev.
Thaum xav txog lub raj amp lub taub hau, nws yog ib qho tseem ceeb uas yuav tsum xav txog hom lub hwj chim raj koj lub amp muaj - lawv txhua tus muab cov suab sib txawv, xws li cov suab nrov ntawm 6L6 lub hwj chim raj mus rau lub suab nrov ntawm EL34s lossis KT-88s. Nws tseem ceeb heev uas yuav tau xav txog pes tsawg watts koj lub amplifier tuaj yeem ua tau. Ntau lub zog amps yuav nrov dua tab sis lawv kuj xav tau kev saib xyuas ntau dua li xav tau lawv li qub hloov nquag thaum siv hnyav lossis gigging tsis tu ncua nrog lawv. Koj yuav tsum tau xav txog yog tias nws yog tag nrho-valve tsim los yog nws muaj cov khoom hauv lub xeev rau kev cuam tshuam thiab lwm yam, vim qhov no yuav cuam tshuam rau tus nqi thiab lub suab zoo raws li.
hybrid
Hybrid amplifier heads tuaj nyob rau hauv ntau yam sib txawv powered designs thiab muaj peev xwm ua ke ob leeg-lub xeev thiab tube technologies. Cov hybrid feem ntau siv cov khoom siv hauv lub xeev kom xa lub zog thaum lub raj tivthaiv ua si ntau dua ntawm lub luag haujlwm preamp, muab kev tsav tsheb thiab kev ntxhib los mos. Hom kev siv tshuab no yog qhov zoo rau cov neeg nrhiav ntau yam amp yam tsis tas yuav yuav cov amplifiers cais.
Hybrid amplifiers tau dhau los ua neeg nyiam ntawm cov neeg ntaus suab paj nruag niaj hnub nrog ntau cov qauv high-end tam sim no muaj nyob hauv khw. Cov taub hau no muaj kev hloov pauv yooj yim, sib txuas ob lub ntiaj teb ntawm kev huv, nkig khoom lub xeev amplification nrog warmer, distortion-driven raj Cheebtsam - muab koj nrog ib tug dav palette ntawm tones los ntawm uas koj muaj peev xwm tsim koj tus kheej style. Hybrid amps kuj tseem tso cai rau kev nkag tau yooj yim rau cov teebmeem xws li reverb lossis ncua hauv lub taub hau amp nws tus kheej, tso cai rau kev siv ntau yam tsis hais koj hom lossis kev ua si.
Cov txiaj ntsig ntawm Amplifier Head
Lub taub hau amplifier yog ib chav tsev uas muab lub zog sib cais rau lub guitar lossis ntses bass thaj tsam, qhov tseem ceeb sib txuas cov haujlwm ntawm lub preamp thiab lub zog amp rau hauv ib chav. Qhov no tuaj yeem muaj txiaj ntsig zoo rau cov kws ntaus nkauj hauv ntau txoj kev sib txawv; los ntawm kev ua kom muaj zog ntxiv thaum sib xyaw suab kom muaj zog ntxiv piv rau cov kab ke amp. Peb mam li tham txog qhov tshwj xeeb ntawm amplifier lub taub hau cov txiaj ntsig hauv cov ntsiab lus hauv qab no.
Kev tswj hwm koj lub suab ntau dua
