Qhov sib txawv ntawm cov neeg hais lus hauv PA System
Main Speakers
Cov neeg hais lus tseem ceeb yog lub neej ntawm tog, cov hnub qub ntawm cov yeeb yam, cov uas ua rau cov neeg coob coob mus qus. Lawv tuaj nyob rau hauv tag nrho cov duab thiab ntau thiab tsawg, los ntawm 10 "mus rau 15" thiab txawm me me tweeters. Lawv tsim cov suab nrov ntau thiab tuaj yeem muab tso rau ntawm cov neeg hais lus sawv cev lossis txuas rau saum lub subwoofers.
Cov subwoofers
Subwoofers yog cov bass-hnyav sidekicks ntawm cov neeg hais lus tseem ceeb. Lawv feem ntau yog 15 ″ txog 20 ″ thiab tsim cov zaus qis dua li lub ntsiab. Qhov no yuav pab sau cov suab thiab ua kom tiav ntau dua. Txhawm rau cais lub suab ntawm subwoofers thiab lub ntsiab, ib chav tsev crossover feem ntau siv. Qhov no feem ntau yog khib-mounted thiab cais cov teeb liab mus los ntawm nws zaus.
Stage Monitors
Cov neeg saib xyuas theem yog cov neeg tsis paub zoo ntawm PA system. Lawv feem ntau nyob ze ntawm tus neeg ua yeeb yam lossis tus hais lus kom pab lawv hnov lawv tus kheej. Lawv nyob ntawm ib qho sib xyaw ua ke dua li cov mains thiab subs, tseem hu ua cov neeg hais lus pem hauv ntej. Theem saib feem ntau yog nyob rau hauv av, tilted ntawm lub kaum sab xis ntawm tus neeg ua yeeb yam.
Cov txiaj ntsig ntawm PA Systems
PA systems muaj txiaj ntsig ntau, los ntawm kev ua kom koj lub suab paj nruag zoo los pab koj hnov koj tus kheej ntawm theem. Nov yog qee qhov zoo ntawm kev muaj PA system:

Keeb kwm ntawm Early Sound Systems
Ancient Greek Era
Ua ntej kev tsim cov tshuab hluav taws xob thiab lub tshuab hluav taws xob, tib neeg yuav tsum tau muaj tswv yim thaum nws los ua kom lawv lub suab hnov. Cov neeg Greek thaum ub siv megaphone cones los npaj lawv lub suab rau cov neeg tuaj saib coob, thiab cov khoom siv no kuj tau siv nyob rau xyoo pua 19th.
Qhov 19 Xyoo Dhau Los
Lub xyoo pua 19th pom qhov kev tsim ntawm lub suab trumpet, ib lub tes tuav lub khob zoo li lub suab paj nruag siv los nthuav qhia tus neeg lub suab lossis lwm lub suab thiab coj nws mus rau qhov kev taw qhia. Nws tau tuav ntawm lub ntsej muag thiab hais lus rau hauv, thiab lub suab yuav tawm mus rau qhov kawg ntawm lub khob hliav qab. Nws tseem hu ua "bullhorn" lossis "loud hailer".
Qhov 20 Xyoo Dhau Los
Xyoo 1910, Lub Tuam Txhab Tsis Siv Neeg Hluav Taws Xob ntawm Chicago, Illinois, tshaj tawm tias lawv tau tsim lub suab nrov uas lawv hu ua Automatic Enunciator. Nws tau siv ntau qhov chaw, suav nrog tsev so, chaw ncaws pob ntaus pob, thiab txawm tias nyob rau hauv qhov kev sim sim hu ua Musolaphone, uas tau xa xov xwm thiab kev lom zem rau cov neeg siv khoom hauv tsev thiab kev lag luam nyob rau sab qab teb Chicago.
Tom qab ntawd xyoo 1911, Peter Jensen thiab Edwin Pridham ntawm Magnavox tau ua thawj patent rau lub suab nrov nrov. Qhov no tau siv nyob rau hauv cov txheej txheem PA thaum ntxov, thiab tseem siv nyob rau hauv feem ntau cov tshuab niaj hnub no.
Cheerleading hauv xyoo 2020
Nyob rau xyoo 2020, cheerleading yog ib qho ntawm ob peb qhov chaw uas xyoo pua 19th-style lub khob tseem siv los ua lub suab. Yog li yog tias koj puas tau pom koj tus kheej ntawm qhov kev tshwm sim cheerleading, koj yuav paub vim li cas lawv thiaj siv lub xov tooj cua!
Nkag siab txog Acoustic Feedback
Acoustic Feedback yog dab tsi?
Cov lus tawm tswv yim acoustic yog qhov nrov nrov, siab squeal lossis screech koj hnov thaum lub ntim ntawm PA system tig siab dhau lawm. Nws tshwm sim thaum lub microphone khaws lub suab los ntawm cov neeg hais lus thiab nthuav nws, tsim lub voj uas ua rau cov lus tawm tswv yim. Txhawm rau tiv thaiv nws, lub voj nce yuav tsum tau khaws cia hauv qab ib qho.
Yuav ua li cas kom tsis txhob acoustic tawm tswv yim
Txhawm rau zam kev tawm tswv yim, sound engineers ua cov kauj ruam hauv qab no:
- Khaws microphones deb ntawm cov neeg hais lus
- Xyuas kom tseeb tias lub microphones tsis tau taw qhia rau cov neeg hais lus
- Khaws nyob rau theem ntim qis
- Kev nce qib qis dua ntawm cov zaus uas muaj kev tawm tswv yim tshwm sim, siv cov duab vaj huam sib luag, parametric equalizer, lossis cov lim dej
- Siv cov khoom siv tiv thaiv kev tawm tswv yim tsis siv neeg
Siv cov cuab yeej tiv thaiv kev tiv thaiv tsis siv neeg
Cov khoom siv tiv thaiv kev tawm tswv yim tsis siv neeg yog ib txoj hauv kev zoo kom tsis txhob tawm tswv yim. Lawv kuaj pom qhov pib ntawm kev tawm tswv yim tsis xav tau thiab siv lub ntsuas ntsuas qhov tseeb kom txo qis qhov nce ntawm cov zaus uas tau pub rov qab.
Txhawm rau siv cov cuab yeej no, koj yuav tsum ua "ntiv nplhaib tawm" lossis "EQ" ntawm chav tsev / chaw. Qhov no suav nrog lub hom phiaj nce nce mus txog thaum qee qhov kev tawm tswv yim pib tshwm sim, thiab tom qab ntawd lub cuab yeej yuav nco qab cov zaus thiab npaj txiav lawv yog tias lawv pib tawm tswv yim dua. Qee qhov kev tawm tswv yim tiv thaiv cov cuab yeej tuaj yeem ntes thiab txo cov zaus tshiab dua li cov uas pom hauv lub suab kuaj.
