Pib dai ib ncig ntawm txhua hom kev kaw cia, rov xyaum ua haujlwm lossis ua haujlwm nyob thiab koj yuav hnov cov lus hais tias 'qib mic' thiab 'kab theem' raug pov ib ncig ntau.
Qib Mic yog hais txog cov khoom siv nyob qhov twg microphones tau ntsaws rau hauv, whereas kab theem hais txog cov tswv yim rau lwm yam khoom siv suab lossis ntsuas.
Qhov sib txawv tseem ceeb ntawm microphone thiab kab-hauv suav nrog cov hauv qab no:
- muaj nuj nqi: Mics feem ntau yog siv rau microphones thaum kab hauv yog siv rau cov twj paj nruag
- inputs: Mics siv lub tswv yim XLR thaum kab siv a jack tswv yim
- Theem: Cov qib sib txawv raws qhov ntsuas uas lawv haum
- voltage: Qhov hluav taws xob ntawm hom teeb liab sib txawv ntau yam
Kab lus no yuav tshuaj xyuas qhov sib txawv ntawm lub microphone thiab kab hauv yog li koj muaj qee qhov kev paub zoo txog kev paub suab thev naus laus zis.
Mic Level yog dab tsi?
Mic qib yog hais txog qhov hluav taws xob uas tau tsim thaum lub microphone khaws lub suab.
Feem ntau, qhov no tsuas yog ob peb txhiab ntawm ib volt. Txawm li cas los xij, nws tuaj yeem sib txawv nyob ntawm qib suab thiab qhov deb ntawm lub mic.
Raws li piv rau lwm cov khoom siv suab, qib mic feem ntau yog qhov tsis muaj zog tshaj plaws thiab feem ntau xav tau lub tshuab ua ntej lossis lub mic rau kab ua kom nrov nrov los pab nws mus txog qib kab hauv cov twj paj nruag.
Cov no muaj nyob raws li ib leeg-channel thiab ntau-channel cov cuab yeej.
Cov khoom sib tov kuj tseem tuaj yeem siv rau txoj haujlwm no thiab yog qhov tseeb, cov cuab yeej nyiam rau txoj haujlwm vim tias nws tuaj yeem ua ke ntau lub cim rau hauv ib qho kev tso tawm.
Cov qib mic feem ntau ntsuas los ntawm kev ntsuas decibel dBu thiab dBV. Feem ntau nws poob ntawm -60 thiab -40 dBu.
Kab Kab yog Dab Tsi?
Qib kab yog kwv yees li 1,000 zaug muaj zog raws li qib mic. Yog li ntawd, ob qho feem ntau tsis siv tib cov zis.
Lub teeb liab txav los ntawm preamp mus rau lub tshuab ua kom nrov nrov los ntawm nws cov neeg hais lus.
Muaj ob txheej txheem kab theem suav nrog cov hauv qab no:
- -10 dBV rau cov neeg siv khoom siv xws li DVD thiab MP3 players
- +4 dBu rau cov cuab yeej tshaj lij xws li sib xyaw cov rooj thiab teeb liab ua cov iav
Koj tseem yuav pom lub suab cim hauv qib ntsuas thiab hais lus. Cov twj paj nruag zoo li guitar thiab ntses bass thaj tsam xav tau kev npaj ua ntej kom coj lawv mus txog qib kab.
Kev tshaj tawm tus neeg hais lus qib yog dab tsi tawm ntawm lub amp rau hauv tus hais lus.
Cov no muaj qhov hluav taws xob uas siab dua qib kab thiab xav kom cov neeg hais lus txuas lus kom hloov lub teeb liab kom nyab xeeb.
Qhov tseem ceeb ntawm Kev Sib Tw Qib
Nws yog qhov tseem ceeb kom phim cov cuab yeej raug nrog cov tswv yim raug.
Yog tias koj tsis ua, koj yuav tsis tau txais qhov txiaj ntsig xav tau, thiab koj yuav muaj kev pheej hmoo txaj muag rau koj tus kheej hauv kev tshaj lij.
Nov yog qee qhov piv txwv ntawm dab tsi tuaj yeem ua tsis raug.
- Yog tias koj txuas lub microphone nrog kab kab nkag, koj yuav tsis tshua muaj lub suab. Qhov no yog vim tias lub teeb liab mic tsis muaj zog txaus los tsav lub zog zoo li no.
- Yog tias koj txuas kab kab theem los rau qib mic, nws yuav dhau lub zog tawm tswv yim uas ua rau lub suab tsis raug. (Nco tseg: Ntawm qee qhov sib xyaw ua ke siab dua, qib kab thiab qib mic cov tswv yim tuaj yeem sib pauv tau).
Tswv yim pab
Nov yog qee qhov lus qhia uas yuav pab koj thaum koj nyob hauv chav studio.
- Cov tswv yim ntawm qib mic feem ntau muaj poj niam XLR txuas. Cov kab hauv kab nkag tau yog txiv neej thiab tuaj yeem yog RCA jacks, lub xov tooj 3.5mm, lossis "phone" xov tooj.
- Tsuas yog vim ib tus txuas txuas mus rau lwm qhov, qhov ntawd tsis txhais tau tias qib sib phim. Feem ntau, cov tswv yim yuav raug cim meej. Cov cim no yuav tsum yog koj mus-rau.
- Lub tshuab ua kom qis lossis lub DI (Kev Txhaj Tshuaj Ncaj) lub thawv tuaj yeem siv los txo qhov hluav taws xob ntawm lub cuab yeej. Qhov no tuaj yeem muaj txiaj ntsig yog tias koj xav tau ntsaws kab kab rau hauv cov khoom xws li cov kaw suab digital thiab khoos phis tawj uas tsuas muaj lub mloog pob ntseg nkaus xwb. Cov no tuaj yeem yuav tau ntawm cov khw muag khoom suab paj nruag thiab tseem tuaj hauv cov kab hluav taws xob nrog cov ua tawm hauv.
Tam sim no koj paub qee qhov pib ua suab, koj tau npaj zoo dua rau koj thawj txoj haujlwm thev naus laus zis.
Dab tsi yog qee qhov kev qhia tseem ceeb uas koj xav tias techs yuav tsum paub?
